I bought my first motor few months ago- Dualsky 6355 12 DA after 20 flights- rubbish- 13 from 14 magnets was wrong- loose position. OK replacement and second motor after 17 flights- big resonance vibration on the middle trothle stick position. Noisy and strange sound. Quality of this motor is lower than Made In China 20 yrs ago. The best is only sticker.
Dualsky that is big sh....t. Now I know why only sposored people heave good opinion about Dualsky.
