Well I've just sprayed the linkages with wd40 had a mess with all the spring bits and the horn and the trim setting on the controller and now when I brake and let off no throttle!! don't know whether it was sticking like you said or it was something else I'm not sure but all working properly now! Well I think it is haha this is my first 1/5 and petrol only ever had a nitro before this also with the big petrols is there normally a bit of lag (don't know if lag is the right word) but like when I try to accelerate it seems like it has to get to quite a high rpm before it moves whereas the nitro just shot off pretty much instant, is it just the clutch on it cause they're centrifugal aren't they? (When I said I'm new to this I meant more of the electrics/servo side of things with the actual engine/carb and other bits I pretty much know what I'm doing) Thanks for all the help aswell!
