1. The native battery quickly failed, maybe some kind of defective, of course, but the fact is, don’t take a ride on your native for a long time, in any case, take a second larger capacity (this is + about 3-4 thousand)
2. In the summer, for some reason, the axles of the wheels bend very easily - I rolled briskly, sharp turns, etc., and the wheel was 8th. I already bought the 2nd set of rear drives, I didn’t see the axles on them separately for sale .
3. I don’t know how it is on expensive models, but on this one there are large backlashes on the drive shafts, on the cardan, etc., a noisy mechanism. Moreover, the crosspieces of the drives are jammed over time after abrupt starts, the holes become loose, there are more backlashes, and the shock loads on the drives grow.
4. on a regular suspension it was impossible to adjust the toe and camber, out of the box one wheel was crooked, I had to buy adjustable traction to adjust the camber.
