5mm of movement is obviously not enough. Maybe 10mm would begin to give you decent response.
if I did that it would roll faster than an Extra or Edge, even the dealer says to use only 6mm of throw..
That is definitely not a warbird flying characteristic. If your pilot thinks that’s how a warbird flys you might want to find another pilot. Lol. I think the opinions you have seen here could be the issue, too much expo, not enough control throw, weak servos.
the friend that flew it is a very capable pilot that has a P-40, you should have seen him land it on it's first flight, he landed it like he had been flying it for 30 years, it was one of the best landings ever.
I agree that the servos are weak, I have some new, stronger ones I will install. but I want to fly it before doing so to test the new balancing.
thanks guys !!
