In fact the G62 will swing a larger prop than a DA-50, it has 10-12 CC's more cylinder capacity. The problem is the weight difference, and where the weight is located on the plane. It doesn't produce enough extra power to over come the extra weight and wing loading. both are great engines. And the zenoha can be made lighter by converting to to I.E.. Knock the weigh down and the zenoah starts to shine.
