having a issue on my msrx. has about 80 flights on it. i have replaced the main motor already. i have batteries that are in good condition. the problem is when i give it throttle it will shut off after like 2 seconds. the binding light shuts off aswell. but when i pull the tail motor out of the socket the main blades spin up like normal and the heli dosent shut off. could it be the mosfets? also how to replace them? location??? any help would be very very much appreciated. thank you all!!
