Hi adrian-RCU,
Thats a nice FUNTANA
I have some questions. How easy is it to hover and what setup are you using? Servos, distance of CG etc..
Didier, what ignition are you using? Are you sure that with an 18*8 prop you're getting 8500 rpm!!! That is quite amazing. I have yet to buy a good prop becasue I have been breaking in the engine with an old Zinger 18*10 wide prop that does not have a good airfoil and I get 6300 to 6400 rpm. Also, I'm using an ZDZ ignition.
Thanks
Sebastian
