Default Bunch Scorpion/Mighty Midget

Hi all,

I recently acquired a short kit for a Bunch Scorpion. It looks like a fun build ahead. The plans show an engine called a "Mighty Midget". I'm unfamiliar with it and I'd like to know the displacement or a modern glow equivalent. Can anybody give me some information on the engine? Any tips on the Scorpion would be appreciated as well. I'll be building it pretty much for sport R/C. Thanks in advance.

I worked on the plan that Bob Holman is currently selling.

But the original Bunch engine was of such a size that it had no A/C suitable for installation. They thus brought out the Scorpion. During the 1930's the firm had some bad times with the original engine, failures, so sold out and the newer and improved engines received the new name. The newer engines are a few grams beefier, better, but.... still carried Bunch in the title somehow.

I think the MECOA Veco line of today is of similar reasoning. No longer around, but still used for titling.

Coos,
That's great information, but it still doesn't answer my question. How big (displacement) was the engine, and what would be a comprable modern glow equivalent?

The Bunch Mighty Midget was a .45 so I guess a modern 40 four stroke would be suitable for your model.

My first gasser was a Bunch Scorpion Major. It flew well with a Baby Cyclone back in 1940.
The Cyke was a .35 engine Ballgunner

If it is a standard size model the you could run a 50 sized Saito.  They make great Antique flyers with ED 3.46 Hunters (yes if carefully flown), I have seen them fitted with various sized 4 strokes and diesels up to 56 size depending on the class flown.  Check with the SAM international site they are the best place to go.
Enjoy the model it will test you
