Stewart,

All good ideas and certainly doable. Will back burner that for now, though it would have been interesting to make up a rear exhaust just to clean up the front profile for cowls and the like. My first gasser was the one that started it all, the Quadra. I made up a muffler/mount using aluminum, rectangular door frame material. The top and bottom were plugged with caps with the bottom one having an exhaust tube. The rear exhaust flange of the engine needed just two more gaskets for a perfect seal with the exhaust going straight back and down. This gave me a muffler with huge volume, very quiet with no loss in power. I have conventional pictures somewhere that I'll try to look up. This was mounted to a big "Ugly Stik" that was modified to look like an ordinary airplane. Outlines changed is all.

I think instead, that I'll make up a conventional style, glow motor muffler but with the necessary baffles to make it quieter. The Walbro carb will be replaced with an Enya .60 or other carb.

I really enjoyed the big airplane with the Quadra and I've flown/run most other sizes planes and engines. If you know me, you know that I also enjoyed a LOT the smaller planes. Missing though was good throttling and full four channel control. Got that beat and needed a new challenge. Diesel did not come to me naturally but I'm glad I got involved. Plenty of challenges here and neat stuff to do. But I never did lose all my attraction for big, but heavy engines or expensive electronic ignition always held me back. And glow conversions? ****edaboutit. At 35 dollars a gallon for even 5%, well,,,,

But a diesel conversion? Now we talkin' turkey. Strip off all the ignition stuff and you get light. Eliminate any need for an ignition source and you eliminate expense. Eliminate ether and it gets even cheaper. Add an easily homemade oil and you get better performance especially with the latest mix that Reg has come up with. Olive might be best but peanut might be second, still acceptable and cheaper. Never know till you try. AND, because we have needles in the right places, what if we could run, oh, say, 5% or less, VeggieLube. Now that would be an inexpensive way to power our flying machines.

And we're not alone in our love for innovation and the unconventional. Will, (Wvarn1957) indirectly has alerted me to this.

These guys seem to be on to something. Like this thread, that one has became a LONG one, some three years running. Yes, I AM going to apply some of those ideas to my little Tanaka. Gas, glow, diesel,, why not.

And actually, Kelly suggested that I check out Will's other posts. Will is a real wealth of information, knowledge and experience. I'm anticipating that he'll be a valuable contributor to our quest.

PS

I may have a lead on another Tanaka that appears to have a square bolt pattern. Neat.
