I upgraded the boys rc from a 7.2 to a 8.4 and put in a metal axle so its 4x4 again, bad thing from ordering from a no namer is its so dam hard to get replacement parts, the dogbone is from some other rc and I had to do some grinding both ways to get it to even fit and its STILL tight. 96.4mm as the replacement length my ASS. My twin brushless comes in the mail today, not sure when I will install as 5 weeks or so I will be going on vacation and would like to bring the rc's with and as of right now mine DOES work and I would like to not chance that in time!
It can be yours for only $589.99.
What rc are you working on? I've been really good at finding parts for stuff.
