Just visit the thread on the MVVS 26cc and see how much trouble MANY of us are having with "black goo" on our planes. I have never seen anything like it, the covering on the stab of my plane is completely discolored from it and there is no way to get it off. I have several glow planes as well as several gassers and with the proper exhaust the glow planes are no harder to clean up than the gassers. I have a pattern ship with a YS 140 / Hatori pipe that you can fly all day and not even have to clean it. Cleaner planes with a gasser is a myth if you do it right.
1 ) - The black goo on the MVVS 26 should disappear once it's broke it. It's normal for this to happen while the rings are breaking in.
No doubt a glow engine with full length pipe is going to stay clean.
2 ) - A glow engine has to put out more "goo" than a gasser. You're talking 20% oil for the glow stuff and 2% for gasoline/oil mix. Where it ends up is due to the exhaust system......
1 ) - That's what they tell me but I have over 5 gals. of fuel through that little engine and there is no sign of it letting up. I'm going to give it another try this season but if it doesn't straighten up someone is going to get a good deal.
2 ) -This is true but it is what you do with the GOO that's important.
Don't get me wrong I'm enjoying MOST of my gassers but I find in the smaller size - under 50cc - the glow engines are less trouble, stink less, start easier, are much cheaper to buy and maintain and power for power a lot lighter. Yes the fuel is more expensive but as I said before I can afford the fuel and if I couldn't I find another hobby.
I don't expect ANYONE to agree with me but this is my .02 worth.
