It's the sound that makes scale aeromodellers smile from ear to ear, the sound that goes hand in hand with models like the Tiger Moth, Piper Cub or even a WW2 warbird. It's the sound of the perfect marriage of airframe and powerplant, its the sound of a four stroke engine!
Who can resist turning their head when a four stroke engine fires up? There's nothing quite like it and with the ASP FS Series you will enjoy not just the sound but the solid performance of a quality designed and manufactured motor.
The ASP FS series engine has been designed by expert engineers and built using only the highest quality materials and CNC machinery. Motors of this caliber provide long life and dependability and ASP have certainly hit the mark with this series.

Good engine,you have to really run them in good because they are a sleeved and ring engine and well built for the money.I had Magnum engines and they preferred 10 percent nitro with caster oil and no lower than 18 percent after break in.The only problem is that they take a bit of time to break in.I use 20 percent for initial start.Byrons 2cycle fuel 10 percent nitro and 20 percent oil is excellent.Incredible engine, best kept secret on line. I actually have 6 of these, the latest arrived today and what a way to wake up my 46 size warbird squadron! Easy to tune and sips the glow fuel compared to a 91. Once run in and tuned, you hardly need to retune and even when so, MINOR adjustment to the top end usually takes care of it. I can't rave enough about this engine.. thank you ASP and HobbyKing!!Excelente motor, muy buenas las termnaciones.
