Did Sachs make a 100cc single cylinder engine for R/C? I bought an airplane that the seller said had a sachs 100cc in it. The builder marked 100cc on the engine that you can view inside the cowl on a 91" TBM Zero. Somebody said it's probably a sachs but not sure. Did anyone else make a 100cc single for R/C? I need to pull the cowl off to look at the engine. just haven't had time.
