Hi,

I'm not sure if there's a post about this already but I'm trying to decide if I should mount my .91 4-stroke Magnum in my UCD 3D. Both of the online reviews available for this plane at the Great Planes website show the engines mounted upside down and one reviewer noted the possible problem with fuel flow.

My LHS guy suggested a horizontal mount like he uses in his racers but I'm thinking that will cause some lateral balance problems.

I do have a .91 2-stroke Magnum I can use instead, if the 4S is out. But the 2S carburetor seems like it will be a little low too.

Enough of my rambling. I'm looking for input from anyone who has set up this exact model, the U-Can-Do .60.

Thanks in advance for the help.

Idaho
