Again I am amazed at the technology ( or lack of it ) in these small RC engines.
Its been shown by tests done years ago that a downward angle of 25* of the Exhaust duct roof gives the best compromise of blowdown flow and duct velocity.
But in the previous post we have a duct pointing upward , surely that alone invalidates any comparison with any other layout considerations.
Ive got a thing thats unique and new.To prove it I'll have the last laugh on you.Cause instead of one head I got two.And you know two heads are better than one.
