I have a magnum .61 which is a bored out 52 2 stroke. Do they make a conversion for it... Also if not What i=I am planing is putting a diesel conversion in a Great Planes Stuka. It calls for a 61 2 stroke / 91 4 stroke... Thought this would be perfect match... No one flys a Stuka or diesel at my field. Any sugestions welcome. Thanks

Its worth a call to Davis Diesel, usually the magnums (asp) are copies
ofOS I don't know about the 52/61 if the bolt pattern is the same spacing
as an other engine he has heads for KB OS etc he may be able to fit you
one up.If he thinks so he will ask to have the glow head sent up If you
want to keep the engine in service an other head is not much I would
guess less than$10 that would give him time to check and see without
a time frame problem

The ASP/Magnum XLS52 is not of the same engine family as the ASP/Magnum XL61 series. Few parts will interchange between them. They don't even look alike. The heads are even different between the ASP and Magnum versions of the 52.

The ASP/Magnum 52 and 61 Four strokes are of the same family.

Enjoy,

Jim

Actually wasn't thinging when I posted the stuff about the .61 What I do have is a ASP .61 4 stroke which is the bored our 52, which by the way runs incredable. Dosn't matter now though because I traded the .61 2 stroke ASP to someone and baught an os. 91fx 2 stroke for the Stuka.
