|M.V.V.S. powerful 2-stroke engines|
|These are powerful engines, make no mistake, they are light in weight with twin ballraces for extra power. Now with the addition of ballraces their performance is unsurpassed by others, and all this at a very reasonable cost. This makes MVVS the choice for experienced modellers and a good idea for learners who are planning to stick with flying model aircraft, and want a reliable, strong engine that will last years.
A special rotation feature of the MVVS S/R type
engines allows either side or rear exhaust configuration. Choose side or rear
exhaust configuration according to your preference, before you run the engine
for the first time.
The fuel for small MVVS engines, is 80% methanol
and 20% castor oil eg GX-5. The small sizes of 2cc up to 4.6cc prefer
The fuel can be have up to 5% Nitromethane for normal use. If you want to use more nitro, the head can be shimmed with an extra gasket in order to lower the compression ratio. But the simple thing is to stick with 5% of nitro which works well. For running-in an MVVs always use Castor fuel such as GX-5.

For glow plugs use the Novarossi C5 , OS No 8, Model Technics F4 or OS-F. These are all available in good model shops.
MVVS mufflers are tuned mufflers: These are very
much like the normal single chamber mufflers, except their volume is tuned to
the engine. Back pressure is increased, and power output is increased. We have
quiet mufflers with added second muffler chamber for ultra-quiet operation
to as low as 74 dB(A) at 7 meters. The quiet muffler removes the high pitched
note from the exhaust sound. it seems to remove every second firing and the
sound that remains is very like that of a 4-stroke engine.
