Hi all,
I've got the servos at the back and a Saito '65 at the front running an APC 13x6 and the balance is spot on. I've no stall problems even when using flapperons just the elevator goes a bit mushy. It takes off in about 25 feet and flies in whatever wind we have, in fact it flies so smoothly two others at my club now want one. I think the u/c must have been up-rated slightly as my landings are not he best and we fly on rough moorland, yet no bending so far (12 flights). I have reinforced the spats and modded the engine mount to take the saito but other than that it is stock.
