The plane is gonna rip apart with that cox .049.Try a Cox .0000000000000049 at idle. Just make sure you get those big 500 oz servos for the engine. And the rudder elevator and ailerons need 100000000000 oz servos just to fly. Just worry about getting that nex 1x 1/2 prop from apc, and keep it at idle so u dont shoot upwards and break the fuse in half.
