here is my PBF plane with a Fox .25 on it using a MAc's Muffler

Here is a Mac's muffler on my venerable Fox 36RC engine as shown here.
it is actually fairly easy to make bridge adapters for fitting different mufflers to the engines.
Here is where I made a bridge adapter to fit a K&B muffler to a old wart Fox .45 engine. You don't need anything fancy for tools, just a hacksaw, drill press (unless you are really good with a hand drill), and some assorted hand files. You can use one piece to adapt or two pieces if the bolt holes interfere with each other.
That PBF plane looks really wild. Is that built from plans anywhere?
The planes are amazingly simple. Here is the original articles and information on them.

They are intended to fly slow like a 3D hovering machine does.
You can also make angled cuts on the front to make them into a delta type of plane if you want to fly faster too.
You can mount the motor mount and spine on the bottom for overhand hand launches. Or mount the spine and motor mount on top if you like the underlanded launch method.
