Any problems or suggestions?

Personal opinion, I like the sideways mounting better than a vertical. Schools out on inverted though. I run a 52, a 91, and a 70 on their sides. And one 91 straight up in a 4*60. I haven't flown the 91 on it's side yet, but the 70 and 52 both run great that way.

As a side benifit, it make tank level less of a problem. Can't think of any cons.

I have an O.S. 70 Surpass II mounted horizontally in my SIG Kadet Senior (pics attached) and it works like a charm. I like mounting engines sidways. They're easier to cool, you usually don't need a remote glow plug and it looks cool sticking out the side of the cowl.

If you're mounting it under a cowl, I found that the metal O.S. engine mount allows you to get a lot closer to the firewall with a 4-stroke. Also, invest some money in the slimline pitts muffler. It looks nice and sounds GREAT!

I just put a slimline pitts on the 91 in my Super Aeromaster. The only down side is that you end up with a huge hole for the cylinder and muffler in the cowl. I've yet to hear it run, I still have some work to do before I'm ready to run it up.

Side-mounting almost any glow engine is OK. You just need to route the exhaust system to fit onto the airplane. Some models don't have room, and you have to perform some "surgery" to fit the muffler.
