Ansmann X4 Pro Diff problems!!!
 

Ran my X4 pro for the first time this weekend at a local race here in Sweden... having some issues wit the ball diff, only after approx 4-6 packs they are crap and feels like there are tons of dirt in them. disassemble them and there are big groves in the diff rings. Is there any other diff-rings and balls u can use from another brand? Seems like the AR stuff isn't the best in quality.

Anyone got some tips for building them and tips of "upgrade" parts!!!

Also is there anyone who know the spring rate on the standard black springs that comes with the kit?

Best regards

You get the grooves in the diff rings from have g your diff set too tight
We have never had any problems with any ansmann diffs

Trust Nic with his advice on diffs, I have first hand experiance of his work. (thanks again!)
Building and setting diffs is not a black art but you must be careful not to over or under tighten them. Additionally pre compressing the spring before assembly helps in the process.

Then ill order some new rings and balls and rebuild the diffs.. and ill be a bit more careful when thightening them...

Should i go for ceramic diffballs or the standard ones?

send a pm to jim76 on here and he will sort you out with some ceramics, cheaper than anyone else about.
To avoid yet another long debate about diff balls, in your position i would purchase ceramic balls.

was thinking of getting some of these kits... http://bfastrc.com/team_c.html
