In my X-6, I run the LRP 6.5T with the 12.5mm sintered rotor and it's geared on 22/78.
Reckon you've definitely got a few pinions in hand Spencer
Thanks for the info regarding the timing etc.
I'm gonna try the off-road profile but possibly up the timing to 6 deg for my X5 - reckon on gearing approx 18/108 or 17/104 to give around 11:1 ish with the 6.5 Losi.
