Hello, Sorry for speaking english, but I speak no german. I'm also trying the wideframe conversion on an ACMA 1953. But I got some space/clearance problem. I'm using the adapter from cargustav and a PX200 engine. The cylinder is very close to the frame, I had to remove some millimeters of the fins. From what I've seen, I need to cut some of the frame to allow more clearance. But as you can see from the picture there is no place for the cylinder head. It's too close to the frame and to the cowling attachment (fixation). What do you suggest ? Thanks for your help.
