Noj Posted April 8, 2014 Share Posted April 8, 2014 18 or 20 pinny, 40t spur. Use the revo spec slipper pads too. Quote Link to comment Share on other sites More sharing options...
DUBZN1 Posted April 8, 2014 Author Share Posted April 8, 2014 I take it that the revo slipper pads are tougher ? Quote Link to comment Share on other sites More sharing options...
Noj Posted April 8, 2014 Share Posted April 8, 2014 Aluminium, very durable. The 20/40 gearing is the max size that will fit. Should be fine for 3 and 4s, however, as always when changing gearing, closely monitor temps for the first run or two Quote Link to comment Share on other sites More sharing options...
DUBZN1 Posted April 8, 2014 Author Share Posted April 8, 2014 Super thank you noj , going to go for 18 first I think Quote Link to comment Share on other sites More sharing options...
Noj Posted April 8, 2014 Share Posted April 8, 2014 Wise choice, I ran with a 2650kv and temps were fine, your can will draw less current so I reckon you'll be right as ninepence fella...still check temps tho Quote Link to comment Share on other sites More sharing options...
DUBZN1 Posted April 8, 2014 Author Share Posted April 8, 2014 Super thanks againWell went out with it this afternoon and temps were fine on standard gearing but I want that bit more out of it - feels like there is room for it anyway Quote Link to comment Share on other sites More sharing options...
kkppww91 Posted April 23, 2014 Share Posted April 23, 2014 Would 20 pinion and 40 spur be fine to run on stock vxl on 2s? Quote Link to comment Share on other sites More sharing options...
Noj Posted April 25, 2014 Share Posted April 25, 2014 Unlikely, it is a big change up from the stock set up... Quote Link to comment Share on other sites More sharing options...
norcoforever Posted April 25, 2014 Share Posted April 25, 2014 20t pinny is a very very tight fit, i tried it and wasn't satisfied with the fit, now run 40/19 with a 2350kv alphastar motor on 3S and it's an animal 1 Quote Link to comment Share on other sites More sharing options...
