Product Description

One of the strongest and most powerful engines in its class RCGF’s compact 20cc Stinger twin has been built to offer years of trouble-free service. Re-designed and re-engineered, Stinger engines incorporate a more robust metallurgy in their parts and a tougher crank system allied to exceptionally high quality bearings. Add this to a case that's manufactured from a tailored no-compromise aluminium alloy and the result is not only an impressive power output but a stronger, more attractive product all round.

Having stood the test of time by providing solid, reliable and powerful petrol engines for well over a decade, greater numbers of R/C pilots are turning to Stinger engines for their aircraft, partly due to the obvious fuel efficiency of the type but also due to the economy of scale that these particular purpose-designed two-strokes offer, especially as an alternative to traditional glow power. If you love engines, as many do, Stinger is the way to go.
