    DLE20 as a replacement for Saito FA-180

    I have a Sukhoi that is at least 10years old... I bought it recently from a guy who used it and other planes to accumulate dust in his garage...

    The Sukhoi has a 75 inch wing span and had a SAito FA 180 on in... the guy said it was way too much power for that plane... I don't know...

    I couldn't get the 180 to fire up so I went and bought a brand new DLE 20 for the plane... I just had a rude thought... what if the DLE20 isn't enough motor?

    the original FA-180 online reviews says it had 2.8HP and the DLE20 says 2.5HP... but horsepower doesn't mean anything.. right?

    what do you guys think?

    RE: DLE20 as a replacement for Saito FA-180

    I am sure it will fly it but I dont think it will hover it at all. From what I have read I think the 20 just falls short of the Saito 150 in power if the Saito is on 15% nitro. I also think the numbers are about 200-400 rpm short of a OS 120 AX. I know many claim it has more power than the OS 120 but in the smaller props around 13-16" it doesnt. it might be close in the 18" size props though.

    the DLE 20 will fly it and hover it but I doubtit will have much ability to pull it out of the hover vertically.

    The Saito 1.80 is a 30cc glow four stroke engine that develops almost as much power as a 30cc glow two stroke engine.
    The DLE 20cc engine is smaller in displacement and also is a gasoline engine that doesn't develop as much power as a equivalent size glow engine does.
    So it may work, but it is hard to say, one guy will claim the plane was overpowered and another buy will claim it is underpowered with a particular engine. But it doesn't hurt to try it out anyway, the engine will power the plane OK, but only you will know for sure if it has enough power for your style of flying.

    Those large glow engines don't need any nitro and not as much oil as a smaller two stroke glow.  Methanol is actually cheaper than gas right now.  If you mix the fuel yourself it will cost only a buck or so more than gas right now.  I would keep the Saito on it and try it.  If it won't fire it is either not getting fuel or has a bad glow plug.
