Great product!
This is where I'm going to use the one I just purchased, so what did you use for a FDR? On of our racers was around 4.1 with a 17.5 and we are running our brushed motors at 5.1 - 5.2.

We had a pretty open track layout (100x40 track, my best lap being 10.7 seconds), and I was geared at 3.37 FDR. For more typical, tighter layouts, gearing is usually around 3.6-3.7.

pm answered if you have any more questions shoot me another pm.
I'm not 100% sure on the gearing now that I thought about it... I want to say at the nats with the 17.5 I ran 3.16-3.23 in that range for 12th scale but I was changing the timing too. ended up about a half a notch off of max timing with the lrp esc... it'll depend on your tracks length and layout so adjust accordingly.



kyle, did you get the 13.5's in yet?

thanks

Michael

You can purchase them online at stomerhobbies if they are in stock still. If not you can contact the office at (480) 726-7519 and put one on backorder.
