GliderThrow - Model Aviation Magazine - August 2025 issue
Here is what our customers have to say about our products and service:
After years of setting up models I can no longer go back to the finger and ruler tools I used for years to set up a model. GliderCG is the essential tool needed to place all of the components inside a modern sailplane before you make the final installation. A small shift in any direction is accurately registered on GliderCG so you know exactly what the placement had done to the CG. Setting up my latest Samba Prestige using this instrument resulted in no nose or tail weight.
GliderThrow is a must have instrument to know the wing surfaces are identical on each side. This matters when you absolutely have to use that 1% extra precise control to work a light thermal. Setting up mix ratio deflections now can be seen on your phone so you know what the deflection is. I could never see that on a ruler! The other advantage of GliderThrow is seeing your control linkage resolution because it accurately shows the final deflection value in degrees at the center point. If your servo linkage is poor you will see it. Accuracy does matter!
Keith K., La Verne, CA
After finally purchasing a Glider CG V3 (after 35 years of building and flying gliders) I discovered my frustrating two jumbo pencil eraser stand was highly inaccurate. Glide CG provides a fast, accurate and repeatable way to achieve the proper CG location especially when installing servos and batteries. Not having one is being 'penny wise and pound foolish'. Whether it is used on inexpensive F3Ls or mega dollar molded F5Js it is a must have tool. Go ahead and make the purchase. You will wonder why you did not do it sooner.
John A., Stuart, VA
"What a great product. I wish I had bought this a long time ago. Super easy to use and balances gliders consistently and accurately within fractions of a millimeter. Shipping was very fast (arrived in three days) and customer support was excellent. I had a few questions and Joe got back to me within minutes. I highly recommend GliderCG."
Ian C., San Diego, CA
"This is one of those rare hobby tools that exceeds expectations on every front. The GliderCG F3K scale offers laboratory quality at hobby prices, with outstanding accuracy and, even more important, rock-solid repeatability. The design is excellent, the materials and finish are exceptional, and the after-sales service is second to none. It’s obvious the product is made and supported by people who care."
Robert R., San Jose, CA
"Received my balancer today - I am impressed. The information displayed on the screen is as sturdy as the machine itself - awesome!"
Stephen S., Cocoa Beach, FL
"I ordered a Glider Throw basic and could not be more pleased. The product was just as advertised and arrived incredibly fast. I will be ordering sensors 3 and 4. soon. I should mention that I had a question and the response was quick ... great customer service and product."
George G., Richardson, TX
"As with others who have commented here the GliderCG has shown me how inaccurate the "finger balance method" actually is. Once you get past beginner planes the GliderCG is a must have tool. It seems expensive at first, but will allow you to get your planes to fly just right, and to manage CG while you're building thus saving trial and error time. My GliderCG machine seems to have had some heat damage from shipping that warped several parts of it. I shot a brief video with my phone and sent a message off to them, I'm very pleased to report that Joe was very responsive in sending me a replacement unit that is not warped in any way and works perfectly. Bottom line: highly recommended product, and with superlative support!"
Randy L., Bend, OR
"I purchased my first GliderGG for F3K and similar sized models last year or the year before. I like the design and technology and it makes for hassle free tuning. It was especially helpful when I went from flying my eCX5 to the newer eCX6. I was able to quickly try different CG positions and come up with a balance that worked well for me at IHLGF this year. Just before attending the IHLGF I decided that I needed the larger model for my F5J and F3L gliders. It also has worked very well and I am glad to have it available as those gliders really need some attention to tuning. Thank you for providing the RC soaring community with these great products!"
Charlie M., Phoenix, AZ
"I tried my 3.4m electric sailplane that balanced out just right on my finger tips! Your scale proved my fingers all wrong flying nose heavy. Love this scale!"
Ray D., Fontana, CA
"I just received the GliderCG in the mail and it works fantastic was so easy to get the center of gravity on my Medina and see what it weighs highly recommend"
Jared K., Cordova, AK
"One thing that keeps coming back to me is the sentiment that a nose heavy plane with fly poorly but a tail heavy plane will fly once. With the criticality of CGs increasing in the highly engineered moldies of today the investment in one of your GliderCG products is cheap insurance against sub-optimal performance of a nose heavy plane, or worse - the loss of a tail-heavy plane!"
Henry B., Gold Beach, OR
"I just wanted to thank you for our efficient support on the timely shipping. You guys are the best."
Gary W., Nampa, ID
"…thank you for following up on your email, your attention to customers is amazing."
Chris C., Glendale, AZ
"Love my new GliderCG scale!"
Don V., Honolulu, HI
"That tool is so amazing. I just ran through all our planes checking them. It’s brilliant how it connects to your phone. So easy."
Chris B., Kula, HI
"Bought one a few months back. Using today after changing motor and other gear out in one of my ships. Not sure how I went so long without one.
If on the fence, then fall off and get one. You will not regret - my new favorite tool."
Mark G., Columbus, OH
"Just received Glider Throw V3 Quad. The removable, rechargeable batteries are a big step forward compared to other models with fixed batteries. I'm looking forward to being able to see the movements of all 4 wing surfaces on my F5J plane."
Jay W., Worthington, OH
"Just received the GliderCG scale. I have used it on my TD gliders and electric planes. It is a very easy to use. The most important benefit is the outstanding customer service that I have received from Joe. All questions that I had were answered promptly. This is an investment in my hobby I wish I had made a along time ago."
Stephen G., Visalia, CA
"For years I have been using the GliderCG scale for all my F3Ks and F5Ks, we recently moved from one state to another, my CG scale was damaged during that time so I contacted GliderCG with no expectation of getting any service just as I had with few other vendors and to my surprise he offered to fix it at no charge. Wow, guess there are great still vendors with out-of-this-world customer service out there! I am a lifetime advocate for GliderCG."
Ben N., Middleton, FL
"Wow! I’ve been flying and balancing model airplanes for 55 years, afforded myself one of those great planes CG machines with post and rule, then I bought your CG plus! What an amazing tool for dialing in the exact balance of any model especially sailplanes! Thank you so much for a well thought out tool to help us fly safely and enjoy our hobby!"
John B., Linden, VA
"Customer Service is second to none. This scale has become a must have tool in my shop."
Jeffrey S., Harrisburg, PA
"GliderThrow makes F5j and DLG setup a breeze! Once you use it, theres no other way!
Ian L., Kamuela, HI
"I purchased the Glider CG machine V3 and the Glider Throw sensors V3 for my F5J 4 meter glider. This was my first glider build and glad I had these two items. Very straightforward on the instructions no way could I get an accurate set up without these instruments. Easy to use. Very well built, a lot of thought when into these product to make them user friendly. Also very fast shipping. Completely satisfied."
Brad N., Forsyth, IL
"GliderThrow gauges are great. When setting up matching surfaces the gauges make it quick and simple."
Tracy E., Spokane, WA
"I have the Standard GliderCG, the GliderThrow 1 2, and the GliderThrow Wing Incidence Tools. Whether setting up a new glider or changing settings I'm assured that I have all my throws at the right starting point and my CG in the location I want. The Incidence tool is always used and integral to my set-ups. The wireless features of both units make using them a breeze. Fast Shipping, great service. I've been using these for over a year, I'm a happy customer!"
Scott H., Canaan, NH
"I'm happy with your promptness. In fact, I already have the GliderThrow Std and use it frequently in my F3A planes. I'm buying it again to give it to a friend who saw me using it and really liked it. Congratulations, the product is very useful."
Cesar R., Brazil
"Hello, this glider C.G. Makes checking and adjusting C.G. Easy. I recommend using it."
Jack B., Lincoln, NE
"The Glider CG weight, CG and angle sensors are an easy to use aircraft setup system that is superior
to any other comparable devices on the market. Well worth it in utility and ease of setup."
Otmar S., Aiea, HI
"I bought a GliderCG F3K scale at this year’s IHLGF in Poway, CA. It enabled me to dial in the CG on all my gliders and with all ballast sets and after repairs. Now all my DLGs feel the same and fly consistently regardless of ballast. Connecting to Bluetooth is great to save models and CG specs. Joe has been super supportive, especially when my brand new scale got damaged in checked baggage on the trip home from Poway. When I told him what happened he asked to me to send him the scale. A few weeks later I had it back as good as new - no charge! The GliderCG F3K is a great CG scale for DLGs and other small models. Product support could not be better. I bought a nice hard case for it to keep it safe for years to come. Thank you, Joe!!"
Jens S., Seattle, WA
"Works very well. I like the adjustability and ease of use. The staff was able to help me with a shipping solution."
Gregg V., Leeming, Australia
"The GliderCG is an essential tool for glider setup. The "Standard v3" with the included small wing adapter is perfect for measuring the C.G. of F3K and F5J models. You don't need instructions; you just turn it on, and it works exactly as expected. It folds up nicely and fits in a small tool bag that goes with the models. Measuring and tuning a glider's center of gravity has always been somewhat of a black art, but with this device, you can measure the CG of your models and, more importantly, use and share measurements with other pilots with confidence that everyone using this tool is getting consistent and precise results."
Luke W., Wilson, WY
"Makes measuring so much easier! The throw meters are working great, really great how light weight they are and doesn't affect control surface throws. The bars are a boon to get the right decalage. Perfect every time. Looking at the CG machine now for F5J, from what I've read it looks the way to go, seen other CG rigs but they seem low quality and don't have features like GliderCG have. Great stuff guys."
Adrian D., Stanthorpe, Australia
"I just used it for the first time today. Works well and seems solid."
Alan S., Arlington, TX
"One of the guys at our flying field had a GliderCG and I was impressed. So I bought one for myself. It took the uncertainty out of measuring and tweaking the CG. Unlike balancing on two fingers, this unit gives repeatable results, and measures the weight too. It is a well thought out and nicely built piece of kit."
Ken H., Wilsonville, OR
"I have been using the GliderThrow for a while now and the results are impressive. It is simple to use."
Dan B., Santa Ana, CA
"GliderCG is a technical wonder. It provides measurements of my model's CG to a fraction of a millimeter! So much more precise than the ol' finger-tip technique that I've used for over 60 years. How did I get along without it???"
Tom W., Iuka, MS
"I Love my GliderCG F3k! So accurate and easy to use without any guess work. I like it so much I came back for the GliderCG Standard and Glider Throws. Thank you Joe for your outstanding customer service!"
Scott H., Medford, OR
"I have almost finished building a 5 meter scale Diana 2 and decided it is worth spending the money on the GliderCG Scale unit to ensure that I get the CG correct - I have too much time and money invested in the glider to crash it because the CG is off a little. As I have seen, with my other gliders, just how important it is to get the CG just right. I have one that I really struggled to fly until I used the GliderCG, now it is one of my favorites."
David B., Pittsboro, NC
"I have recently transitioned to F5K and smaller gliders and my standard CG scale was just too wide to accommodate the narrower wing cords of F5K glider. This GliderGC scale is perfect for these smaller gliders. I also really appreciate the rechargeable built in battery, the bright readable screen. "
John H., Peyton, CO
"My Glider CG machine works like a champ. I use it on my F5J competition gliders to fine tune the CG for the best in-flight thermal indication performance."
Larry A., Forestell, MO
"The GliderCG scale is fantastic! Easy to use and sure more accurate than the manual one. Glad I purchased the product. Thanks, Joe!"
Mark K., Westlake Village, CA
"I’ve used GliderCG scales for all my gliders, ranging from 235 gram DLGs to 26# 1:3 Scale glider. I have two scales and two sets of the digital throw meters that have enabled me to precision tune & balance all of my planes. The customer service is exemplary and I highly recommend these devices to anyone interested in getting the most performance out of their models as possible."
Steve L., Fremont, CA
"If you are serious about flying a properly setup glider, this CG scale is a must have. Previously I used the finger method, and a home made jig. Both of those methods were not accurate and awkward. With the CG scale I know my precise CG and weight in a matter of seconds. My gliders are now flying much better."
Tom C., Marietta, GA
"The GliderCG is a great piece of equipment. Now using on everything!!! Buy with confidence!"
James T., Folsom, CA
"I would like to thank all the good people at GliderCG and GliderCG USA for helping me with a recent problem. I dropped my scale and broke some parts. I contacted GliderCG and they respond quickly. They were able to replace the parts and even sent me pictures with instructions to make the repair - all at no charge! Great service from a great company. Thank You!"
Brad J., Surprise, AZ
"My GliderCG scale is really nice - it is simple to use and very accurate. Now that I own one, I use it a lot more than I expected. Thanks for a great product!"
Art C., Thousand Oaks, CA
"Have balanced my 4# gliders (Explorer) with a lightweight balance tool – to the mm. New glider is 14# so the normal balancer was way too lightweight. So I did some checking and it appeared that people made what’s called a ‘Vanessa Rig’ – a piece of wood, dowel, and two loops of line, one around each wing root. Plumb bob attached to the dowel, get the plane level and wherever the plumb bob points is your CG. Did that with the new plane, maidened it and the CG was WAY too far aft. As the saying goes, a nose heavy plane fly’s but not well, a tail heavy plane fly’s once. That was accurate! Purchased the GliderCG machine and it worked very well – to the tenth of a mm if you want. Very pricey but it’s accurate.”
Rick S., Reno, NV
"Terrific products and incredible customer service. Highly recommend!"
Jon H., Kaneohe, HI
"Really easy to use. Gives CG and weight of the model instantly”
Dave H., Honolulu, HI
“I bought the DLG version of the GliderCG. This has allowed me to fine tune in a way never before possible the flight characteristics of my gliders. Well made and easy to use. Highly recommended.”
James D., North Vancouver, BC
“I am using the GliderCG Scale, the largest, on my 1/5 scale RC airplanes. It is great to set the CG and get the airplanes weight.”
Bill D., Kailua, HI
"Customer service was great. Scale shipped and arrived in 3 days by USPS. Scale works great! My CG was off on a couple of my sailplanes. Now that they are fixed I can't wait to fly them. Scale is simple to use and understand. The Wi-fi feature is great to keep track of all your gliders CGs. All you do is put your sailplanes name and where it should CG at, then next time click on your model and the CG is there."
Ed H., Visalia, CA
"The GliderCG is a valuable tool that exceeds my expectations. Joe has been great to work with, and has answered or got the answers I had in a very timely manner. Highly recommend his products. "
Justin R., Phoenix, AZ
"Scale nice - Andy like"
Andy T., Thousand Oaks, CA
"Great products and support. Best customer service bar none!"
Jack L., Chicago, IL
"I thought I had set the CG’s of my gliders accurately. But, was still having issues with stability, particularly the 3.4M Silent. I read reports about the GliderCG and decided to get one. The GliderCG allows me to get accurate weights and CG’s. It is amazing how just a few mm’s affects the flying characteristics of these high performance gliders. "
David B., Pittsboro, NC
"It is a really neat device."
James D., Vancouver, BC
"Works great, easy to use! Very nicely designed, and clean aesthetically. I like that the posts fold down to save space while storing. The customer service was great, helping me select the appropriate scale for my range of models, and shipping it out quickly. "
Eric I., Park City UT
"The GliderCG Scale Mini was direct shipped from the manufacturer in Spain. It was well packaged and arrived in perfect condition. The arm on the Scale Mini fold down for easy storage and have nice keeper brackets to keep the arm upright when raised. The Wifi interface works well but does take a few seconds to connect sometimes. The lateral balance feature is a nice addition. Overall, a great product."
Jim G., Portland, OR
“I am really happy with my CG scale and now use it for all my rc models. It’s very accurate and the CG scale also gives total weight. Fast shipping and really quick communication from the company”
Richard A., Smartsville, CA
"I'm truly impressed by its stability; there are absolutely no wobbles, and the readings are impressively consistent, showing less than 1mm in CG variations. I want to thank you for the exceptional customer service. It's been a pleasure dealing with your team. I will recommend your scale to my friends who are in the market for one."
Peter P., Millburn, NJ
"Valuable and convenient center of gravity and surface deflection measurement tools. Very helpful for setup of my F3L and F5J gliders. Friendly and responsive service and support."
Mike S., Woodside, CA

The customer service is exemplary and I highly recommend these devices to anyone interested in getting the most performance out of their models as possible."
Steve L., Fremont, CA
"If you are serious about flying a properly setup glider, this CG scale is a must have. Previously I used the finger method, and a home made jig. Both of those methods were not accurate and awkward. With the CG scale I know my precise CG and weight in a matter of seconds. My gliders are now flying much better."
Tom C., Marietta, GA
"The GliderCG is a great piece of equipment. Now using on everything!!! Buy with confidence!"
James T., Folsom, CA
"I would like to thank all the good people at GliderCG and GliderCG USA for helping me with a recent problem. I dropped my scale and broke some parts. I contacted GliderCG and they respond quickly. They were able to replace the parts and even sent me pictures with instructions to make the repair - all at no charge! Great service from a great company. Thank You!"
Brad J., Surprise, AZ
"My GliderCG scale is really nice - it is simple to use and very accurate. Now that I own one, I use it a lot more than I expected. Thanks for a great product!"
Art C., Thousand Oaks, CA
"Have balanced my 4# gliders (Explorer) with a lightweight balance tool – to the mm. New glider is 14# so the normal balancer was way too lightweight. So I did some checking and it appeared that people made what’s called a ‘Vanessa Rig’ – a piece of wood, dowel, and two loops of line, one around each wing root. Plumb bob attached to the dowel, get the plane level and wherever the plumb bob points is your CG. Did that with the new plane, maidened it and the CG was WAY too far aft. As the saying goes, a nose heavy plane fly’s but not well, a tail heavy plane fly’s once. That was accurate! Purchased the GliderCG machine and it worked very well – to the tenth of a mm if you want. Very pricey but it’s accurate.”

"Terrific products and incredible customer service. Highly recommend!"
Jon H., Kaneohe, HI
"Really easy to use. Gives CG and weight of the model instantly”
Dave H., Honolulu, HI
“I bought the DLG version of the GliderCG. This has allowed me to fine tune in a way never before possible the flight characteristics of my gliders. Well made and easy to use. Highly recommended.”
James D., North Vancouver, BC
“I am using the GliderCG Scale, the largest, on my 1/5 scale RC airplanes. It is great to set the CG and get the airplanes weight.”
Bill D., Kailua, HI
"Customer service was great. Scale shipped and arrived in 3 days by USPS. Scale works great! My CG was off on a couple of my sailplanes. Now that they are fixed I can't wait to fly them. Scale is simple to use and understand. The Wi-fi feature is great to keep track of all your gliders CGs. All you do is put your sailplanes name and where it should CG at, then next time click on your model and the CG is there."
Ed H., Visalia, CA
"The GliderCG is a valuable tool that exceeds my expectations. Joe has been great to work with, and has answered or got the answers I had in a very timely manner. Highly recommend his products. "
Justin R., Phoenix, AZ
"Scale nice - Andy like"
Andy T., Thousand Oaks, CA
"Great products and support. Best customer service bar none!"
Jack L., Chicago, IL
"I thought I had set the CG’s of my gliders accurately. But, was still having issues with stability, particularly the 3.4M Silent. I read reports about the GliderCG and decided to get one. The GliderCG allows me to get accurate weights and CG’s. It is amazing how just a few mm’s affects the flying characteristics of these high performance gliders. "
David B., Pittsboro, NC
"It is a really neat device."
James D., Vancouver, BC
"Works great, easy to use! Very nicely designed, and clean aesthetically. I like that the posts fold down to save space while storing. The customer service was great, helping me select the appropriate scale for my range of models, and shipping it out quickly. "
Eric I., Park City UT
"The GliderCG Scale Mini was direct shipped from the manufacturer in Spain. It was well packaged and arrived in perfect condition. The arm on the Scale Mini fold down for easy storage and have nice keeper brackets to keep the arm upright when raised. The Wifi interface works well but does take a few seconds to connect sometimes. The lateral balance feature is a nice addition. Overall, a great product."
Jim G., Portland, OR
“I am really happy with my CG scale and now use it for all my rc models. It’s very accurate and the CG scale also gives total weight. Fast shipping and really quick communication from the company”
Richard A., Smartsville, CA
"I'm truly impressed by its stability; there are absolutely no wobbles, and the readings are impressively consistent, showing less than 1mm in CG variations. I want to thank you for the exceptional customer service. It's been a pleasure dealing with your team. I will recommend your scale to my friends who are in the market for one."
Peter P., Millburn, NJ
"Valuable and convenient center of gravity and surface deflection measurement tools. Very helpful for setup of my F3L and F5J gliders. Friendly and responsive service and support."
