Neu motors not as good?

[superek4]

I have a 1515/3d spoil due to short wires internally. Repair won't be cheap, it makes me think that neu motors are not suitable for off road as it has a wire issue.

Should I just use it as paper weight or repair it?

I am currently using my spare tekin 1550kv. No issue.

I am trying to sell my 1512/2.5 but no luck also, seems that neu hand madr motors are not as good as neu castle as they are build for cars?

I am Disappointed.
