OK thanks. I was looking at the at the rules posted on the USVTA website it doesn't state anything about gearing. Just specific speed controls and the Novak 25.5 motor only along with the spec tire and body rules.

OK. So it sounds like basically the same gearing Im running on my 17.5 TC. I wasnt sure how much taller a gear the higher wind motor would pull. I can start there and see how it goes. I just though considering the motor is fixed there may be a pretty well targeted FDR for this setup.
