RE: XYZ 20cc engines from Valley View
I bought power hd 1501 and had centering problems could not use them on elevator or rudder as plane never flew horizontal. So replaced them.
Got bitten this time looking for the bargain. Will use them in airbrake brake aplication, or flaps where centering is not critical.
The xyz 20 seems like a nice low price motor. Have a pattern plane missing a motor (focus sport) and don't want to go the glow fuel alternative. To expensive for the size of plane.
Mody what hapenned with your other project you where building?
cheers juan
