It seems strange that there would be 2 different motors if they both do the same thing. Could be the only difference is the lead colors, but since the motors turn in opposite directions they may be more effecient when running their designed direction. As this heli is wired - the motors are turning the wrong directions.
Think I'll swap and wire the motors correctly and see what that does.
