MVVS is a Czech company who make engines ranging from 2cc to 20cc. I have used a 2.5cc glow and diesel in my rat racer and find them very impressive. The glow will start with one flick most of the time if the settings are right and with spin at about 26000rpm with the right prop. MVVS engines are of a high standard and cheap with the 2.5cc engines costing only 90 aussie dollers.
