The flight board has DSM and S-bus sockets - use a satellite receiver and your own better transmitter! Also mount the ESC outside the plane behind the prop for better cooling - some folks have reported overheating!.

Also reinforce the front section with bamboo skewers along the side of the battery area and across between them at the front. Then wrap plastic zip ties around motor mount and back to the bamboo reinforcing. The foam will just break behind the motor mount in a crash otherwise. The landing gear is only for decoration. Any even mildly rough landing will just rotate it around in the thin foam. Replace with 2 loops of zip ties or line trimmer cord glued under the wings. Much better to absorb a rough landing!
