I have installed some of the parts from my old Rex X on to the eBay one.
Mainly the engine and tuned pipe (there is a nice tuned pipe included with the eBay one which I will try at some stage)
I had some difficulties getting the 2 speed clutch connected to the crank shaft on my engine as the crank shaft seemed to be a tiny bit too short. I managed to get it on using a temporary solution for now.
I also cut out the required pieces from the new body shell.
A few more bits to do tomorrow and it should be ready for a test drive 🙂
