No boxer of adequate size will fit. Surprisingly narrow cowl. Requires either large single or Moki 250.

A BME 116 extreme will fit right in. The BME is 10-1/2" wide and the Meister cowl is 11-1/2" at the spark plug location. You wont have to even cut a relief hole in the cowl for the plugs.
Plus a BME is more like a 140 0r a 150 twin, and is simply a "Beast"
That inline twin will work too, but good luck with the cooling of the rear cylinder...

Good luck too...

HAve you considered rocking the boxer-type engine about 30-35 degrees to get a boxer in the cowl? I have a Jug with a 3W150 that is set-up this way to make it fit in the cowl. My cylinder heads sit at about 8 and 2 o'clock.

Never thought about rotating engine mount. Out of the box thinking. Thank you.

You bet, and it has not affected the engine's operation one bit.

I'd like to see pics of how you put in the exhaust system in the rotated twin cylinder configuration. Thanks.

I actually sold the plane to a friend, but it used the stock 3W canisters, with extension pipes riveted on to flush with the bottom of the cowl. Flex tubes were used for one of the cylinder to bring the exhaust down. I can see if he will snap a picture for me if you want.

I have been looking at their 64cc inline for a 109 that I am building.

The 64cc inline is something that I have been waiting for a long time now! I am guessing it will run a lot smoother than most single and fit a 1/5 scale warbird easily.

I may have to go ahead and order one. The good part is that from the front, it has the same foot print as a 30-35cc engine. Obviously longer, but each cylinder is only 32cc. That means shorter height, much more narrow cylinder head and smaller muffler/header dimensions.
Cooling will suck unless you have a P-40 or P-51 or some other plane with a chin scoop. The 109, Spitfires, Hurricanes, etc will be tough to cool. I have some thought about cooling the 109 by using the oil cooler to suck in cool air....still working on the exhausting of the hot air part. Not matter what, tight baffling it probably the key so that all fresh air goes through the fins.

Well Jeff the only thing that concerns me about 64cc inline is the length of the carb stacks. Carbs might actually stick out from the side of the fuselage.

In my application, it is not a problem, but yes, it could be an issue I fear. My have to clock the engine a bit and come up with an exhaust solution.
The 109 fuse is nice and fat right where those carbs are since the inverted DB engine has the exhaust on the lower middle of the fuse. Mustangs and such with the high exhaust and cowl that tapers could be a problem.

I bet two of these would sound great on a P-38

JeffH if you are thinking of putting an inline into a 109 it may work out well do to there is a natural cooler vent in the lower cowl for the
engine cooling some thing to think about I think it would be a great match
