RE: flip the motor on U can Do 3d 46
For whatever it's worth: I flipped the engine to upright on my UCD3 .61 size because I hate fiddling around with low end mix and regulators, yada. yada. yada. Upright doesn't affect the thrust line or the fuel draw and the engine runs great with minimal hassle. I love the UCD3, but I think worrying about how it looks is kinda like worrying about whether Brett Favre combs his eyebrows.
