I would go with the BME. It is 2 pounds lighter than all the other engines and it has tremendous power. Just my 2 cents.

I heard there was a durability issue with that motor, did they get it worked out?
Either way I'd go with the

DA

I went through this a few months ago buying the engine for my 33% Extra 330L.

First off, both are great engines, and great customer service.

The BME is lighter, and will fit in smaller cowls like the Extra without cutting holes for the spark plug caps.

The DA will fit within the Cap's wider cowl.

The DA has more torque, and the additional weight helps balance the H9 airframes that were designed for the heavier Zenoah engines.

For my plane, I went with the DA, even that it meant cutting more holes. If I were building a plane that had a lighter tail, then the BME would have been chosen.

DA

I never heard of any durability issues. It is a geat engine.

Check out some of these post, they have bogus info in them. Either motor will do fine. My personal choice would be the DA 100. There are pros and cons of every motor, I think the DA is the best of the two. Look around to what the Pros fly, they wouldnt fly the DA if they didnt beleive in it.

Jeff..just incase your not on it.. You on the Airtronics Users Group???
