Alo, Robert!

I don't know what CL Carrier rules you are using. If .40 cubic inch is a rule, you've made a fine choice.

Some years ago, Claus Maikis' website included a small plan of a profile semi-scale Me-109T (Traeger) for CL Carrier. He had an interesting 3-line system, elevator (Hohenruder) plus throttle (?Drossel?). It still may be on Claus' website. A friend of mine set an AMA(USA) Profile Carrier Record two years ago, with a model of an Me.109T. Not Claus' version...

Turning the front parts of some engines 90° gives you reversed rotation. We mostly describe prop rotation as we look at the model from in front, where we flip the prop. So, going over the top from right to left we call counter-clockwise. Reverse rotation goes over the top from left to right - clockwise.

Some engines of high power are made with a front end intake and bearing unit that can be turned 90° to give reversed rotation.(Port is turned 90° and shaft meets it 90° sooner or later - total: 180° shift. (Kurbelwelle?) port timing may not be as close matched for high power when reversed; manufacturers (Herstellern?) sell the best they can, for the use they expect.

I have flown an ENYA engine reversed this way. Good power, but I did not try to compare it to original power. That was over 50 years ago. Since, I have flown a stunt engine with factory reverse timed crankshaft. Same power, only needed a reverse rotation propeller. They were more available then - early 1990's.

Herzliche Glueckwuensche!

Or am I a messy Sprachenmetzger?
