Conversation with Matt re: 'H' version, July 6, 2001

He expects this engine to be brought out in an 'H' version for helicopter application in the not to distant future.

Engine development / Tuning:

He sees no problem with the carburetor mounted under the engines. He said that gravity does come into play as a small disadvantage and the needle etc. may have to be changed.

Matt said that Sportscopter had to use different needles for the 2 cylinders because of the different manifold lengths.
