Thanks for all the input guys.

I'm still thinking about the Poulan though. That Katana seems to consistently come out tail heavy from other posts I've seen, and I'd rather add an ($80.00) Poulan than dead weight.

If I do it, and I probably will, I'll let you all know how it comes out. I'll keep the engine as light as possible. It may take me a little while dollar wise to get it all done, but this sounds like a fun project.

BTW, I just ran my little Kioritz 16cc conversion today. I got 7000 rpms on an APC 15 x 8 prop. This is with the engine completely stock except for a muffler I made out of a butane refill can, and a CH ignition "kit" that I bought and installed. I'm really pleased with it. I would post a weight ready to fly for you, but the digital scales I just bought doesn't work. (Neither does the Glo Bee Tach I just bought!!) Had to fall back on my old reliable; my ACE R/C analog tach!

Thanks again and have fun,
