HI,BREL,This was a simular pblem i had with mine ,but mine was the airsoft gun ,had it fixed now when i switch on my tank it recoils out of its own,to get a decent operation out of them you must get a better electronic system and its costing money.My plem is nobody here does the hop ups in south africa so with the exhange rate its costing a arm and a leg,my other one the left rear track keeps on jumping in the split of the idler then i must remove the track and refit it .i take of the front idler and then without splitting the tracks i take the track of and refit it,its saving a lot of pt but i havent got a fix for it. frans muller gauteng s africa[sm=cry_smile.gif][sm=drowning.gif][sm=punching.gif][sm=spinnyeyes.gif][sm=thumbs_down.gif][sm=angry_smile.gif]
