It's not bad competition wise...I'd not win a national currently but I also suck as a driver so ROFL...
To hide the cost from the wife....I'd just use the orig kit with Ball bearings and go from there... total cost for the kit would be About £55 That's one decent trip to the pub

... the motor that comes with it is pretty decent for buzzing around
If you get the bug for buggies again The Base Madrat is quite upgradable but If you do the maths you'd be better off getting an X Pro and using the old Madrat you have for spares. That's probably how I'll progress with my 2wd racing.
