After the successful start with the cordless drill I decided to replace the broken pull starter with a drill start
I got the Fastrax Force Backplate Torque Start and I also got the Fastrax Start Shaft
I also ordered a new body shell, wheels and tires
And I decided to buy a second had Rex-X on eBay, I was looking for a doner car however the one I have purchased looks in very good nick. I will wait to see when it arrives but my old car may become the doner car if the eBay one is as good as it looks in the photos. Its a rolling chassis with servos, no engine and has a 2 speed upgrade. It cost about €145 including delivery.
