Thank you CHRIS ! At last someone has given me a solution . Replacing parts left right and centre does not make sense to me . Once again thank you CHRIS I will invest in some alloy diffs etc !
A solution to a problem at last ! Wonder why HPI could not give me this info ?
I own 2 and if the diff packs up after 1 1/2 fuel tanks on a flat surface and whilst treating the vehicle with care as I am not yet used to its handling , it is a BABY !!!!!
I am most definitely not new to the Rc game , I have owned 4 GS RACING VEHICLES ( 2 BUGGIES AND 2 TRUGGY ).Never have I...
As far as I can see there is no repair here .You have shimmed the diff shafts , however the problem is the insufficient gear tooth contact in the diff between the diff gears 86023a ( large gears ) and 86032b ( small gears ).
This is a factory fault and HPI IS NOT TAKING RESPONSIBILITY TO REPAIR...
