Hi guys. I bought a motorised kit built 03/04 today. It looks to me very much like the Airfix kit, but there are no marks to identify it. What is confusing me is that there are split axles on the engine, but they don't meet! As a result, there is nothing to stop the wheels falling out one side, with spectacular results! Has anyone replaced the axles on one of these kits, or got any suggestions what I might use to do it?
