Rossie is an IP engineering Rapier fitted with 4 wheel drive and onboard 2.4GHz 2 channel radio control for speed and forward / reverse. Onboard power is provided by 4 Nimh rechargable batteries with the charging socket located underneath.

A bit of a squeeze for the electronics but it all fitted in under the bonnet with the battery pack and receiver under the dashboard inside the cab.
