Hey Scoeroo,
Yes I believe you are right, composite are so perfect,& when you buy a viper or something of that arf always seems to need trimming badly, same as when you scratch build one the incidence has to be so perfect or else again you will need to trim it. I know a couple of guys with composites & they flew like it they were on rails no trim required on any movement. I can remember a while go when I went & had a look at the pylon racing a guy had a brand new viper, he was trying to start it but had flooded the engine, & cause the engine was so flooded when he went to turn it over again, sort of jammed up the crank from turning over & it broke the back end of the fuse where the v-tail connects to the fuse. Broke it in half before he even got to fly it. Man that would really piss you off ah lol
