Held in by the clear plastic cover on the back, some rubber fittings on the wires should keep the muck out.
On the other end, there is a small gear, driving a bigger one. Two ratios are available - high and low ratio. I've plumped for the low ratio one as again, I'm a bit nervous how fast this thing is going to go. On the plus side, this means more torque for off road performance. If I get a bit more confident, swapping the gears over looks possible. I'll keep them for the future.

Motors...I remember the "standard" motor used on a lot of r/c cars being the RS540 but there was also something called the RS540SD Black Motor which was advertised as "Ball raced, very fast"! I never found out, as I couldn't afford one.
Something else I recall was the 20A(or was it more?) fuse on my buggy glowing red hot when you went from full reverse to full forward in an attempt (usually unsuccessful) at a wheelie. Oh, and Ni-Cads that lasted about 5 minutes...
Simon - I think the battery on my Boomerang lasted about 12 minutes before needing a recharge. I did think about going over to ball races in an effort to improve battery life by removing some of the friction from the drivetrain but never did. It's been in Mum's loft for far too many years now!
