N8B, actually the mod is pretty simple. I don't have the time, means or machinery to do it, but a machinist could easily make the spindle on a CNC lathe, the Traxxas 32p clutch bell is readily available and the stock motor plate only requires two new holes (actually only one for the new motor mount, as the spindle uses the upper motor mount hole and only needs a bevel so the screw fits flush). I want to do a lot more testing, but the mod looks very promising.
