hey all, new to this aircraft forum but not new to the site(had a car). ok anyways i have a plane with dual engines and when i have the trim set even(so no props are spinning) then i hit the throttle and one of the engine spins faster than the other. im not sure but i think that they are dual 180 engines. i checked all the connections but there seems to be no problem. also when i have the throttle off and i just hit the left/right the right prop is spinning slower than the left by alot. What do you guys think the problem might be? i was thinking maybe just a falty engine but i really no nothing about it.

thanks for the help Boarding
