Ansmann racing SC4

[RadioFish]

hi guys, over a year ago i bought an ansmann sc4 purely based on the price (60 quids) now I managed to build it and thought it was O.K apart from body post holes not being in the right place (eh?) and had to wait and buy servo esc rx/tx battery all separately, finally got it all working and diffs wjere dodgy i have since completely tightened the diffs using the centre screw thingy and am still having problems with rear diff (keeps sticking) anyone else had one of these cheap and cheerful trucks and had similar problems need some kinda advice oh and shocks leak like a sieve.

PLEASE HELP

The SC4 has got ball diffs from memory, which the manual doesn't describe very well how to build.

When you say that it keep sticking is it the diff action that feels sticky or the diff rotation?

Most ball diffs need to be fairly tight but not to the max ( too much load to the thrust)

Is the screw securing o ring the right side of the screw (common build error with those due to the above)?

Are the balls/plates correctly greased? (One side/not too much)
