You need to come to fly over country, IE MN.

Status: offline 		Well, I am one who is venturing into diesels. Haven't flown an IC since I was a kid. Since I get back in the hobby in 2003 I have flown electric. In fact, if it had not been for electric I would not be in RC now. Why? 2 reasons. First, the closest IC field is over an hour from my house. Second. I still remember hard to start engines. I know that's changed now, but, it stuck in my mind.

Since I've been flying RC I have found the convenience of electric and the ease of finding a place to fly to be a big advantage of electric. I also don't like the scream of a 2 stroke glow engine on a scale plane. 4 stroke is a bit better and 4 stroke gas is better. Then I got to see some diesels fly (thanks to Steve Staples). Perfect combo for the WWI planes I usually fly. Lower rpm, larger props, great sound.

So, I have a PAW .06 (thanks to Eric Clutton) that I have installed in a previously electric WACO SRE. I look forward to flying it.

Will diesel become a mainline item. I don't think so, for the same reasons listed, smell, volatility and availability fo the fuel.

Status: offline 		Andy,

Only about a month late to yours of 13 June: The aluminum alloy used in ABC construction is often described as a "high silicon alloy" which has an expansion rate similar enough to the cylinder brass to allow the cold-pinch/hot-fit conditions. High silicon Al alloys, I've heard, are harder on tooling, too...

Commonly available aluminums are not likely to be just the right silicon alloy composition. Purer aluminums expand quite a bit, as you've apparently observed. Iron-ringed aluminum pistons in older engines had a fairly generous clearance between piston and cylinder - it was the ring's job to make the compression and power stroke seal conditions... The aluminum was there to hold the ring, and to weigh less...
