Hi All, thanks to everyone for the advice on brushless systems for my ZX5.
I just want to make sure I've set my buggy up right for the change in power (plan to run 5.5 motor), if anyone can offer any more tips on what I should do to ensure reliability, that would be most welcome. Here's what I've done so far (RTR version) -
Proline tyres
Ceramic balls in diffs (shimmed fairly tight)
3 Racing heavy duty diff tubes
Ceramic outdrive bearings
Aluminium suspension hinges
Lunsford turnbuckles
Decent oil in shocks
SP motor mount
3 Racing Aluminium hubs front and rear
10 degree front hubs
20 tooth pinion ready for new motor
Now before anyone bags me for buying the RTR version, that was my best choice offered by my wife's budget, now that I have it, she has no idea of what I spend on it

, so I don't mind spending money to get it right.
