I currently have both UCD models. I run the .46 with a saito .65 on it. This combo works well for mild hovering and 3d. I have the .60 UCD sitting in my garage with no motor and was wondering if a tower .75 with a 14X4 prop would work well on this plane? If not, has anyone had the .46 size with the tower .75 at their field? Just trying to check out my options. The motor is just sitting collecting dust and it was such a good running motor and strong motor too!
