So i recently bought and built my gremlin, but haven't flown it until now because of the cold. Upon first flight, after giving it the smallest amount of throttle, the quad sporadically twitched and yawed. So, i went back and hooked it up to betaflight, took off the props, and went to the receiver section. Double checked that all inputs looked good there. Then i went to motors, where i double checked the direction of each, all good. I then tried to recreate the incident, so turned on my Tx and gave it a bit of throttle. Instead of seeing all 4 motors go up, there was complete chaos. While that was happening i checked my Tx again just in case, and all good. This seems like a FC issue to me, since the motors were reacting fine one at a time through betaflight. Any one else have any other ideas? Think they will replace my FC?
