Hi Jamie
Looks like another OS45 FSR clone like the Magnum 45, ASP 45 , Thunder Tiger etc. I'm sure with a light weight muffler 6 mm venturi and low pitch (11.5x4) it would run real fine! It does need a good seal so as long as compression is fine it should be worth adapting to C/L Stunt.
 Unless an all out racing or ducted fan engine you can normally adapt them fine to stunt , only have to watch the weight especially with factory mufflers but if you build tail heavy their is some good nose weight .  ;)

Hi all.

Matt, it seems to me the same as my LEO 46, a chinesse copy of the OS 46 SF (the same for the 40), with true ABC piston liner assembly (bought 2 of them some years ago in Hobbiking at 36 USD each...... ~^ ~^ ~^
The LEO 28 btw is a good powerplant for Super Clown or Rigmaster type models.....
Reasonably well made, the worst part are the bearings, but this is easy to solve.
Almost impossible more for less..... ;D ;D ;D ;D

Kind regards.

Manuel.

     The Leo/Brat 28 was one of the engines I tried in the "small engine" experiments and it is indeed completely usable for our purposes, and 35-sized profile models, using the formula. I think it liked the Tornado 10-4 and APC 10-3, but that was a long time ago.   I know for certain that at least one National Champion started out with a Leo 28 on a UKey 35 (2006 Senior National Champion Paul Ferrell), because I think he ended up with my Leo 28 thrust washer, when his got dropped in the gravel and lost at the Alameda field.

Im undecided if I want to keep this Tower .46 for a stunt application or not. Not sure if its worth even fooling around with since I have a few .46LA's.

If anyone has experience running this engine Id like to hear some thoughts. The muffler it came with is huge!!!! Much bigfer than a stock .46la muffler. And the Tower.46 surely feels heavier than .46LA.

It's a bunch heavier. It's a ball bearing motor. I have 2 on RC planes and they are strong runners but I think too heavy for any .46 sized planes when you can use an LA. They do make tons of power though. One pulls my Kyosho Mustang at 85mph.
