I need a little info on a motor. In April i bought an Arrma Big Rock 3s V3 version. I have run it less than 15 times (never in wet) and the front motor bearing has blown out, I am currently trying to get it warrantied, but if i can't, I'm looking at the 1412 1y as a replacement for it.
My issue with it is the stock pinion shaft size is 5mm, where the castle site shows the 1412 1y as having a 3.175 shaft (1/8"). If the castle guys are still lurking, Can the 1412 1y be ordered with a 5mm pinion shaft?
I'm not worried about the overall strength of the 1/8" shaft, I am more than certain that it'll be plenty strong enough. But if I don't need to buy a new pinion, I'd rather not.


Thank you for any info you can share
