DYS D3542 1000KV/1250KV/1450KV Brushless Outrunner Motor 2-4S for Multicopter RC Aircraft Fixed-Wing UAV (D3542 1450KV)

To anyone discovering this thread in the future, the issue was the motor - it was faulty from the factory... I ended up going with this exact motor and it works perfectly now, and it really rips!
