Yeah I've heard a lot of people have done this with this plane and it makes a massive improvement. Unfortunately, I've only got a 4ch transmitter so can't haver the flaperon feature :-(. Though, I was thinking about having a servo in each wing just to get better/more precise aileron control, do you reackon it would be worth doing this even though I won't get the advantage of the flaperons?? I find the current aileron servo setup is a bit poor really and never seems to return the ailerons back exactly to neutral position when you let go of the sticks...

P.S have you got any pictures of the wing with your new flaperon setup?
