I used the throws indicated in the manual cd. The CG was a bit to far forward for my liking, I have it at 170mm from leading edge, instead of the 150-160mm indicated.

hope this helps,

Didier

The F-15 will soon be ready to fly.
Can anyone else comment regarding the CG and control throws ? this is probably a popular plane.

Hi, Skymaster´s settings are pretty good.. mine is flown on tailerons with 50mm up/down and 25mm left/right and 25% expo. CG as manual, and it is not very critical, as I didn´t notice any drastic stability change while fine tuning it to my taste.

I also flown and helped to dial a friend´s F-15 with tailerons and aleirons.. we ended with the same taileron settings and very little aleiron deflection (we matched the side view angle of both surfaces by the eyeball method. Once this was made, the airplane got as smooth as it should be.

appreciate if you can provide total weight (less fuel) on your F-15s for comparison.

Thanks, I like it, it´s quite unusual and different... took the idea from a RCU friend´s Mirage some years ago.

i just weighted mine dry with everythign but the turbine itself (ECU, pump etc all installed) and its right at 9Kg. i'd estimate about 10 Kg dry (22lbs) RTF with no fuel.
