You get quality and reliability with OS

These engines are so good I normally fit OS engines in all my planes.
OS FX Series
  • All FX engines come with remote needle valve - a very good safety feature - keeps those fingers further from that prop!
  • Front and rear ball bearings increase reliability, power and life.
  • Excellent, smooth, trouble free carburator that is very easy to set up.
  • Semi-square head shape creates more fin area to increase cooling capacity, hence power and reliability.
  • With the 0.61FX & the 0.91FX there are 2 possible mounting positions for the remote needle valve. On the 1.60FX the remote needle valve assembly can be mounted three different ways.
  • A longer output crankshaft allows for fitting spinners, prop and retaining nut.
