I'm pretty darn sure that I'm going to use my TT 46 Pro. I've got this thing lying around, and the whole plane was litterally designed around it. I'll be VERY surpised if it needs any ballast.

I have thought that a nice Saito 82 would be nice mounted inverted... I love the Saito in my Cub. I doubt I'll ever buy another 2 stroke (this 46Pro was bought years ago and never used).

But then I'll still have this engine lying around... So, I think I'll use it.

I'll probably mount it up and check the balance. If it needs a stupid amount of nose weight, I'll go for the Saito. Otherwise, I'll put the 46 pro in.

When I say "designed around it", I mean the holes predrilled in the firewall position the engine diagonally, so the muffler comes dead center down the middle of the fuse. They partially cut (dotted line with the laser) the wood in the area around the muffler so you clear it out, and glue in this plastic concave bubble to clear the muffler. It's a really slick setup, and really hides the muffler.

This makes the engine head stick out of the cowl a bit, so it's not as scale as I'd like, but it's a lot better than 99% of the other 46 size sport-scale planes.

If you mounted the engine straight down, it would be completely enclosed, but you'd need to do something with the muffler. I didn't see any inverted Pitts style mufflers I liked. I'm leary of the strap on ones.

I thought of getting a fuse mounted tail wheel, but I didn't want to deviate from stock too much. I'll give it a shot. I haven't had a problem with this setup before, but don't have much experience. What should I look out for?
