Something happening in the engine conversions section of RCU, people are running their gas engines on a mixture of 1 part 10%nitro 10% oil glow fuel to 2 parts gasoline; this leads to a fuel of roughly 27% methanol, 3% nitro, 3% oil, and 67% gasoline. Some have successfully flown their engines with 1 part methanol (racing fuel, I think about $3 a gallon) to two parts gasoline with some Klotz oil added until it's about 3% of the mixture. Using a glow plug, no spark plug needed, and with some nitro it's just like a glow motor. General consensus is about 200-300 rpm gain over stock gasoline with a MASSIVE reduction in weight. One guy has a 25cc weed eater brand conversion at 1lb 12oz, which I think is pretty amazing. That's a 1.52 gas engine at 1.20 4stroke glow engine weight. This doesn't even include the weight saved from being able to use a smaller fuel tank.
Made this post because I'd mentioned it to people at the field and nobody had heard of it, so I thought I would pass it along. Not sure how many of you are into tinkering or trying new things but this sounds fun. I've currently got a 23.6cc Kioritz (Echo) that I'm going to run this way, as soon as I can trade my way into a suitable airframe for it. Speaking of which, anyone have a .90-1.20 four stroke sized plane they'd be willing to trade for a Ryobi 31cc gas engine converted to R/C use, or possibly a RTF Walkera #4 micro heli? Maybe both?
