Hello
nice to see your beatifull plane and little 4 stroke flying.
I can see too many hours at job to convert the little gem.
I am put your german post in google translator and see you have problems with crankshaft, I am sorry, but this happens.
In the club a modeler get a Honda four stroke like yours, dont know how many cc have but come from a weedeater dissasembled because the engine start to burn too much oil. Need repair and spare parts are expensive here.
Your engine have chromed cilinder liner?
Thanks for posting your job, numbers.
Good white fumes , do not have problems clogging the little diameter tube to heat the liquid for smoke?
That engine is my dream, but I will buy four stroker when to Argentina come the chinese clones, cheap, dont know when, but when I catch one you will be the first person to know how perform the engine.
Compliments for your fine job.
Jose
