O.S. FS91 Surpass IIFI w/F-4020 Sil
The only four-stroke engine in the world with 'fuel-injection' this is targeted at models designed for the old class of 61 two-stroke engine butwith the possibility of sound levels that are much lower and the operating technique used in the bigger 2M FAI aircraft.
The computer controlled 'fuel-injection' system is similar to that used on the Max 160FX FI and is simple to set-up and operate.
The FS 91 FI now boasts an amazing combination of power, throttle response and light weight in a compact package.
