VM-engines are now being produced with state of the art machines and methods.

The Valach Motors VM R7-800 just looks like a real radial engine, only smaller, above all it sounds like a real aero radial engine. Not improperly smooth, like smaller radials. The absolute scale flight with the marvellous sound from that large capacity radial engine can, if at all possible, only be bettered with a full-size machine.

The big capacity per cylinder, the valve timing and the supplied ring shaped silencer are responsible for the realistic sound on idle and on part load. Like all Valach engines, the response to the throttle being opened is so smooth without the slightest attempt to surge.
Valves and their seats are manufactured by Honda, ensuring a very high quality. Due to the inclined valves, the combustion chamber is shaped more like a hemisphere. This improves the combustion and the engine has a higher performance. In addition the fuel consumption is lower than otherwise.

The crankcase, cylinders and cylinder heads are cast like with full-size aero engines, which enables a light weight and the VM R7-800 with the casting surface finish has a very realistic appearance. Due to the steel cylinder liners this engine will have a long life.

We have fitted an electric petrol pump, the VM R7-800 is easy to start and in every flying attitude has a reliable petrol feed. After sucking in with choke closed the VM R7-800 starts after the first or second flip.

The processor controlled ignition allows easy starting and a exceptionally smooth running in all throttle settings. The ignition can be operated with a two cell Lipo battery

We had tried many oils, but recommend Valvoline SynPower 2T oil.

We recommend Aral Ultimate 102, as the smell is not so penetrating and it can be stored without deteriorating. It does not contain any ethanol.
For a good throttle response in all RPM ranges, we recommend the use of an intake RAM tube.
