Got both trucks finished up Friday night and delivered on Saturday. I ended up using the output shaft I made because the replacement from FLM still hasn't arrived. In the future I will keep using my proven parts with the GA bulks and UE diffs, they have never given me any troubles and don't require any mill or lathe time. Im sure it won't be long and both trucks will be on lipos as soon as the kids get used to the NiMH speed.
