Default RE: Walbro conversion for OS 160FX

Hey guys,

When you come to think of it, it doesnt seem feasible to buy and convert a 160FX to gasoline. And I wouldnt  have done it if it wasnt going into a pattern practice plane. Dont think about the money you spend on conversion, as it amortise fairly quickly because you are burning free gasoline fuel..  If I were in US, I wouldnt even think about this conversion, because the glow fuel is so cheap.. Here, like the rest of Europe, Im paying 40-45USD for a gallon of 15% nitro byron, wildcat or Omega..

Im still running my conversions, and this one with the pipe is over 35liters of gas, 30 liter of it with a 20:1 oil-gas mix. 30 liters ofgasoline would equal to more than 60 liters of glow fuel. Roughly 60lt= 16 gallons. that would mean around 700 USD for glow fuel. and Ive spent around 100 USD for gas and oil.. thats 600 bucks in pocket

On the 160 FX the tuned pipe and header is adjusted so that, like a 4 stroke, the engine would have optimum rpm and huge torque over the rpm band. Instant transition. It easily rivals 140RX on pipe. and I can confirm here that 160FX on gasoline with long pipe; out perform a YS140 running on 20% nitro..

If you are not going to use a pipe on the engine, there is no point of making this conversion. If the engine is going in a sport plane or slow flyer there is no need. Even for 3D, I dont recommend it. I would buy a MLD 28cc and get the nearly same performance.  But If you fly your plane alot, with a tuned system, then it may turn out to be a real money saver.
