On this site you can see the complete conversion of a Mathe Competition. My friend Klaus Detro has reengineered all parts by his own ideas. The result is an engine with less weight, more power and smaller sizes. He uses an ignition from a Zenoah G230Rc car engine. The pullstarter is replaced by a pulley to start the engine with an external starter like the nitros.
The pics shows all details and, of course, the assembly of all parts.
Now the engine is installed into a Supercat II from Paul Swaelen. More from that next time...
