yes i added longer arms on the ailerons but they really arent needed... and i used 1.5" servo arm elev and i can get over 40 deg in any direction, and 1.25 for rudder

i used 5925(old hi speed hitecs) and 5625 on elev and rudder and a 625 on throttle...

for the maiden flight.......with the wings and hatch on i CGd it right on the wing tube.. i got some kite string and made a quick cradle

im happy to help
