gmaxx trans question

[Rivermaxx]

So I assume somebody made them @ one time? I am pretty new with the emaxx and dont know the complete history of aftermarket parts for the tranny. Can you fill me in? I found a gear maker that can make any gears too your specs out of delrin,phenolic, aluminum ,steel, brass.stainless ,cast iron, hardsteel. Not sure on prices but I will check it out on monday to make a delrin or phenolic gear to replace the 2nd speed gear in the g-maxx tranny.
