I could, but what fun would that be?:027:

Actually, the store bought FOC doesn't address the issue of locking the second gear to the Primary clutch. Which means you can't use the motor to reverse the geartrain, correct? (I haven't seen a Revo FOC installed, so I don't know). Do you keep first gear in the tranny with a FOC installed?

My other rationale was to try this as if I had zero budget (there are always folks who save all their pennies for new motors/controllers, and have nothing left for anything else). Usually, this quickly degrades to me building/milling some elaborate piece that costs 50 times what a store bought piece would - but that is one of the most enjoyable parts of this hobby for me...
...building parts!
Fortunately, this is a pretty simple conversion that requires no extra parts to purchase. Wouldn't even need a tap if you were to drill/pin/epoxy the parts together.
