hello i need help with my genesis i got it second hand from a freind but the gearbox was broke so i paid £200 to fix it after taking it out for about 10 mins the gearbox broke again so i took it to the same shop and he said that they are prone to it because of the plastic being able to move a little bit and then the gears hack each other up firstly anyone got any ideas if this is true and is there any way to fix it or shall i just sell it and get a more reliable tmaxx 3.3 ???



please help!!!
