Setting Up a 2-Stroke for Direct Drive
This thread is dedicated to the memory of Mark Stull. May he rest in peace with a new set of wings.------------------------------------------------------------------
Mark's documentation of DD 2-sroke operation cáught a lot of us by surprise. Especially his experience of his DD setup, which he said performed as well as the reduction unit he had been using.
The experiment ended when his MZ-201 engine with about 400 hours of DD use failed due to a rod bearing. (He made a forced landing which he walked away from, but the airplane was badly dammaged.)
Having said, that I wanted to explore the concept a bit more with maybe some further possibilities.
All insights and comments are welcome.
After reading some material suggested by another member (we know who you are) I got the impression than one further thing that could be done, is to re-port the engine for lower rpm with high temperature epoxy.
Also using a carb with a smaller flow to get more mixure accuracy and response in this lower RPM range.
I'll start there and see if anyone has any opinions on this, or more ideas, be they supportive, conflicting or in totally different direction.
