I got my kit on Wednesday and built it for a shakedown run at SHRCCC indoor on Thursday night.
Had the same issues as other people on this thread, but nothing to major.
I moved my ball joints on the steering drag link to the rear and set the EPA lower to stop the steering going over centre and jamming. Not ideal I know but it worked, and I was definatly not lacking in steering.
Regarding the diff, I set it the same as other diffs, fully tightened and backed off 1/8", this was fine and didn't think it an issue. To note, the ears on the nylon nut did not go all the way down to the end of the diff out drive, I tightened it up by feel, and when the suspensions goes up the drive shaft has the absolute minimal movement so it will not be in contact with the nut.
My issue has been with the rear shocks. With the shock fully compressed the piston protrudes past the damper body by 2/3 its hight. This doesnt seem right, but not noticeable on the bench or the track. Has any body else noticed this?
To add, Im running SMC lipo's that are 24mm tall, and the battery strap didnt secure this, in fact it was quite a long way off with refrence to the strap locater at the rear. With the lipo blocks fitted it also had 5mm movement fore and aft. I have addressed this with foam but it would have been good to have the option in the kit.
When I built my B4 there was an explination to the technical steps, damper filling and bleeding, starting set up on the diff and slipper and a base set up (albeit for US dirt tracks), while not essential to experienced racers it would have been good to have it in the manual, and yes I know there is an online resource
The car ran extremly well though, and changed some things and it should be good to race next week. On the whole a very good kit and should be an excellent car.
