Made a new thread for this as the old one got a bit messy and it's now only as a roller, including a servo.
I put a pack through it when it arrived and it all works well, bit of play in the front left wheel, I've not investigated what it is, but nothings snapped as far as I can see, it's just wear and tear I think (maybe a bearing at worst)
Comes with an unknwon brand servo (not took it out to check) but it works fine.
Not a right lot to say about it really, I just won't be using it now I've got used to the handling of the SC10 and I'm very happy with how it's set up as well.
Looking for £50 posted including Paypal fees.
Maybe open to trades on electrics (1/8 motor or ESC or LiPos)
