I would be interested in the 24P Bravo should you decide to sell it.

IMO that would be a waste of time and money. 3 blade in any pitch is going to have more slip than a 4 blade on take off. A rev 4 like others have mentioned is probably your best bet. I can almost guaranty that bblades would tell you the same thing because thats what they told me when I was having the same problem. They (bblades) will also let you try a prop, with a nominal fee, to see if it works the way you want it and then go from there.
