MVVS 91
 

Go to

www.justengines.co.uk

and click on the MVVS pages. they have the specs. on this engine. Performance and power to weight ratio wise it is an alternative to an OS 91FX. Rear needle valve option is available too, if you like RNV motors. Best of all, MVVS's like low or no nitro fuel.

Hello!
The MVVS runs good. It has the new MVVS carb with 10mm intake hole. It is a ABC engine with a steel muffler( but buy the quiet silencer instead as this muffler has larger volume)The crankaseis the same as for the 10cc MVVS engine.
You can see a picture of the engine at my homepage
