Well folks, bit of an update on this thing,
Currently running this combo in it but cant remember what kv the motor is, its either 3400 or 3800, and with a 16T pinion if I remember correctly.

Also with these batteries, fits nicely so they do

over all I am rather happy with it, Ive broke both A arms and the rear spoiler, A arms broke from a rather slight tap off a kerb and the other one was a tap off a wall, so some bits seem a wee bit weak.
with the power combo i have in it i haven't managed full throttle with it as its stupid fast, gonna go to a big car park at the weekend and see what it does might also strap my old Blackberry to it and put the gps app on it to see what speed i can get outta it.
haven't tried jumping it yet as i fear alot more parts might start to break but if i get a chance I'll give it ago lol
anyway so far so good, for the meantime anyway
