Hallo Model engine friends from all over the world. I will start this new thread with a couple of words to thank Mr.Chris Boll from England for all is help and advice when needed during the making from my engine and of course for his nice design from a simply constructed model engine which the Boll Aero 18 is. This model engine can also be built by people who have n't lots of experience in working with "High-Tec" maschinery and constructions in metal and aloy. I hope that the photo's made during the production from my Boll Aero 1.8 will give the readers/visitors of this website the enthousiasm of making such an engine themselves. Greetings from Modelmotor-Europe.
