It came to my attention that there is a possibility that the front and rear diffs in the RTR versions of the Hyper 7 (RTR, PBS and PCR RTR) may not have lube in from the factory. This was noticed after I opened up a few diffs on peoples new rides. This only seems to be affecting the Standard diffs and not the Spiders, If you have one of the said buggies then I strongly recommend opening up the diff to check. This will also cause a loud squealing noise when in motion and premature failure of the unit.

Just looking after your pockets.
