That is a Helmut Bernhardt. It's made in W.Germany(Introduced in the early 70's) and is a good quality engine. A bit heavy but made good power for it's size. Some came with PDP porting in which there were red or black painted letters PDP on the lugs indicating Perry Directional Porting. These were popular in the mid 1980's. Mecoa still sells parts for these engines. Ken

Thanks Ken, I fly alot of rc and used to fly cox models in the seveties.I am going to try my hand with a little bigger u-control this year. I bought a 34 inch Sig Akromaster . Do you think this engine is a good fit for that kit?

The Sig Akromaster was designed for a Fox .15 which is very light compared to that engine. I used a Enya .15 for some time but it suffered from nose heaviness issues. It worked when 7/8 oz's of weight was added to the rear but I was never satisfied with it's overall performance. The plane can be made to fly better if the wing span is increased a rib bay inboard and outboard. I've used the LA .15 successfully on the plane. Ken

Just be aware that the LA will make the plane nose heavy. Shortening the nose could help here but keep in mind that you don't have much to work with behind the engine to leading edge for tank space. Using no muffler would be most helpful due to lighter and also the fact that it may present problems with landing gear interference. Ken
