Hi Guys ,
This is a qustion for my 3.3 conversion , I use a Titan 775 and EVX-2 .

I notice on the slipper / spur assembly there is no spring on the nitro transmission like electric EREVO's ... on the nitro tranny it is just a washer on the back , washer on the front and the nut . do you add a spring for the conversions ?? I was getting WAY too much slipping so I just tightened it all the way down . But now its a wheely monster , just looking for a happy medium .
