I maidened my Cougar this morning, I still have a smile on my face
Everything went great, I made three flights. The cougar is also way faster than my brothers panther!
The CG at 80mm was a good choice, if flew perfect from the beginning.
About the mounting of the main retracts, I just mounted my main retracts with 3 screws. It still is firmly in place, I had one rather hard landing due to being to slow during landing, but nothing happened fortunately.
Please mount the electric retracts. my brother first had the mechanical ones in this panther, the gears were perfectly set up but still he burnt the retracts servos several times! I added some pics of my gear mount, maybe it helps.
