This is my first RC plane. I've been on simulator and feeling confident enough for first flight. Problem ... i turn on the controller (all lights are on) connect battery in plane. i hear one or more of the servos 'twitch' then .. nothin happens. not able to control any of the plane servos, motor, etc.. I've googled for solution for about an hour now, and not coming across any solid recommendations. Thanks in advance for any thoughts.</p>
