Looking for a small engine.
Looking for a small engine.
(OP)
I've been looking and looking for a small engine, an RC size, small engine that preferably would be a gasoline engine as apposed to nitro. The one thing I really need is for it to NOT require mix to operate. Preferably it would have an actual wet sump. I'm trying not to have oily blech exhaust.
Anyone got any ideas?

Scotty; OSI are first rate and need only 50:1 oil ratio but still need oil in the gas.
Greg; Right!
I'll look into how the little diesels are lubed.

RE: Looking for a small engine.
You must be aware of them, so I'm guessing you want more than 15 minutes of endurance, and/or a very heavy payload, in which case the Honda posted by Greg begins to look about right.
Have you got a decent guess for wingspan or weight yet?

RE: Looking for a small engine.
I hunted down several diesel RC engines hoping they didn't need 'extra oil' but they actually do need all sorts of additives like castor oil mixed with synthetic oil. Blech.
I guess I'm going to have to get one of those OSI four stroke gasoline engines that need only 50:1 oil mix and see what kind of residue/mess they make or, I hope, actually DON'T make.
Oh yeah IR, I don't think I'm up for $2k+ nano-turbines!

I'm thinking that a muffler with internal screens might catch a fair proportion of the lube oil, to be cleaned occasionally, or maybe drained overboard in use.

RE: Looking for a small engine.
Greg I'd not thought of that an excellent point that I shall follow up on.

RE: Looking for a small engine.
But then, I have to wonder what type of weed whacker or hedge trimmer you're using or possibly the oil to find the exhaust so bad. Maybe your mix is a little oil heavy? I found my 2-stroke Stihl to be pretty good. Doesn't smoke and the exhaust area stays clean using their oil at their recommended mix ratio.
RE: Looking for a small engine.
That is, you still use the recommended ratio, but this oil is suitable for use at 100:1 ratios.
If your engine requires 16:1, you may use this oil, but at the recommended 16:1 ration.
A logger friend of mine, years ago, found some oil rated for 50:1 and started using it at 50:1 mix in his saw that required a 16:1 mix.
It cost him a large and expensive Stihl chainsaw finding out the difference.
