hasnt arrived yet been 10 days. the original metal wore out in a couple weeks with the stock 390 motor. the plastic 1 seems to hold up better which I just put back in, with a brushless 4800kv so hopefully these metal spares will hold up better. This needs to be metal/steel not aluminum metal. Same with the ring gears, although no probs with those yet. Perhaps it was defective? Idk until these arrive and are put to the test.
