Description
While building my Pilot-RC F-16 (1:5 scale), I ran into the same issue many owners have experienced: the supplied 3 mm plywood CG tool is simply not strong enough for a jet weighing around 24 kg (53 lbs).
In my case, the original tool cracked after only a few seconds under load.
To solve this, I designed a robust and easy-to-use 3D printable CG balance tool that allows quick and repeatable center of gravity checks.
✔ Designed specifically for the Pilot-RC F-16 1:5
✔ Supports CG positions at 270 mm, 275 mm and 280 mm
✔ Much stronger than the original plywood solution
✔ Fast and repeatable balancing process
✔ Ideal for workshop and field use
The design has been successfully tested in both PETG and PETG-CF.
Standard PETG already provides excellent strength, while PETG-CF offers even greater stiffness and durability.
This tool was designed around the Pilot-RC F-16 in 1:5 scale. Please verify the fit and support points on your own model before use.
I hope it helps make CG checks quicker, safer and more accurate.
Happy flying!
