Hi,

I have modified a couple of Mamod Roadsters. They have a few issues they are very heavy and the transmission poor driving through one rear wheel unless the floor is very flat the drive wheel can lift off the floor so loose traction.  The reversing system used isn't very good and doesn't allow the cylinders to use the steam as well as they could.

This video of the results of me playing with a Roadster might be found interesting.



I also made a three wheel version a 'Mamod/Morgan' which used plastic wheels and was a lot lighter and because of it three wheels solved the traction problem.  It performed better but still wouldn't manage much of an incline, both models would steam continuously and it was good fun converting them.

Take care Tony.
