roadhor & OnTheEdge: Thanks for the tips guys, I'm using a 13 x 8 prop only because I can't seem to find a 15 x 4w at my LHS yet and I hate to order just one thru the mail. I will get one in time and hope to have some better performance.

OnTheEdge: I know what you mean about channel 52. I have that channel and almost used it in my UCD but decided to go with 46 instead.
