Hi I did a search and did not find any thing about this so I will post something I posted on another forum here. This is a mod that I did to my Raider XL but it also should work on all of the other Arrma RC's that seem to have this same problem. The stock ball studs in this spot are to short to do there job properly. I was half way though my third run when this ball stud "UNSCREWED ITSELF" and the other side was on its way to doing the same thing. The turnbuckles will act like a wrench and slowly turn the ball studs out. Arrma sells the 4.5 X 13mm ball studs for $6 a pair, or you can get the Duratrax 4.5 X 15mm ball stud 4 pack for $2.70. After putting the longer ball studs on, put a locking nut on the other side like I did in the picture. Doing this will prevent the ball studs from ever coming out again.
