Awesome airplane for IMAC competition, used by a champion in southeast region, has won many times, beautifully trimmed with optimum side and up thrusts, flies straight with perfect down lines and up lines. I hate to alter for 3D, although it hovers at 1/3 throttle and easily does basic 3D maneuvers on hi rates. 3W 150 B2, mejlic 3blade prop, MTW cans, pwrrbox programmable SC12, power box spark switch, fromeoco 5200 x2, ignit 2300 lith. Hitech on ailerons and JR 8411 multiple on rudder and ailerons. It will be the prettiest and quietest, perfectly trimmed 40% in the competition line at any IMAC competition. This will be ideal for a relatively new IMAC competitor wishing to advance from basic or sportsman and aspiring to win trophies. However, It can be an awesome all around 40% for some one to fly normal aerobatics and light 3D for fun.
