I have been flying a UCD 46 for 1 1/2 years. I had a YS 63 on it first. The YS generates 8 lbs of thrust according to my scale. It will hover the UCD which weighs a whopping 6 lbs. I switched the YS to a 4 lb Burrito and put an OS 91 4 strokeon the UCD. The 91 really pulls it around like it means it. More thrust than I need but not than I like. The OS generates 10 lbs of thrust. Your engine will stain a gut to produce more than 6 lbs of static thrust.
First I have the UCD and a few profiles. I like the proflies better - they are more agile, more rugged, and easier to work on as the wear and tear of 3d learning sets in. The UCD 46 is a 60 size plane with a 46 label. With your engine you will get a few seconds of hover or something close to it . If you put it on a 4 lb plane you can 3d - not great but OK.
I wouldn't worry about the looks of a profile. They look fine in the air and you are going to ding up whatever plane pretty quickly. Your 3rd 3d plane can be pretty if you are into pretty.
Ditto for what Jack is saying. I have both the UCD 46 and a profile. The UCD is great but definately more of a 60 size plane and really is more fun to fly with a larger engine. Also, I thought the profiles were butt ugly at first but I bought one after seeing one fly and now I love the one I have and am building another one......[8D][8D]
