Hi all.
very recently my son was given a thunder tiger mta4 by my brother. Something he used to use regularly but did no servicing on.
after a long period of it not being used, we got it going and today we took it out so it could stretch its legs.
we had run 2 tanks through it and all was working well after a few tweaks. Literally as we were about to pack up and leave, the car lost drive. The car was revving but it would barely drive forward. A little better in reverse. If I lifted car up and rev, all wheels spin. When on ground, it won’t move.
if I spin a wheel, the opposite wheel spins so guessing driveshafts ok? All grub screws and nuts are tight.
Any ideas what I can check to diagnose problem? Remember, we are new to this so not too technical please.
thanks
steve
