I'm running a sp v1 but I had some issues with it on sat. A couple of times it would not bind up so I had no throttle and it also shut off once and then just come back to life? other then that the sp has been a great speedo....
I'm sure they fixed those problems on the v2 but for the price of just the sp speedo I can have a losi combo kit
also What ever you order be sure to get the long sensor wire or You'll be sol when you go to put it in
