March 27, 2013Application(s): Propulsion of a two-wheeler.
Comments: Pros: ball bearings
Cons: big dead zone (about 0.12-0.14ms); 1.5ms neutral point is not centered within the dead zone; another 0.02ms on each side of the dead zone give you shattering movement; two motors I got was so badly different I had no luck to synchronize them up to any reasonable point.
Conclusion: Do not waste your money! Go with modification of HS-422. It gives much better results for less money. I feel robbed for 34 bucks. Thanks to HiTec for manufacturing this garbage and to RoborShop.ca for having no a customer review option on their site!
