The flaps aren't cut out on the Bix3 are they? if they're not cut you can just leave them as is.
for the rest you're a bit low in information. for the motor you may need to try calibrating. have the throttle at max when you power on the receiver, then after it beeps, reduce the throttle to lowest.
and for the aileron check the connections, does it use a Y splitter ? does white go to white on all the connections.
Take pictures of everything and provide as much info as you can.
