Bought this motor to replace another of the same model that had terrible vibration problems, turns out both motors had poorly balanced bell housings from the factory that required some stickers to properly balance. Unacceptable level of quality control from Xnova factory on this one, looks like I'm not the only person whose received a poorly balanced motor from the factory lately. Please look into it. Otherwise great motor once it's properly balanced.
awesome motor. Quality looks incredible. Dealing with a main was awesome. Definitely we'll buy more product from this company.
Awesome motor as always plenty of power for the Goblin 580
I don’t what magic xnova use. But that motor runs very cool and very efficient and i love it
the motor have a lot of vibrations or that it is not balanced or that the shaft is bend not sure what, but the Icon2 detect 4 time the allowed vibration for normal operation, when I run only the motor and pinion, even not the rotor head and tail very disappointed
Reviewers largely praise the motor's power, efficiency, cool running and build quality, with several noting strong performance in 580-class helicopters. The main recurring problem is vibration: one reviewer reported a poorly balanced bell housing on a replacement unit, requiring balancing stickers, and a verified owner reported vibration readings four times the allowed limit when running the motor and pinion alone, suspecting imbalance or a bent shaft. One reviewer also praised the seller's service. One review came from a buyer who had not yet run the motor. Reviews do not specify whether the vibration issue affects all units.
