Bryan has decided to sell me the prototype (it took awhile but finally, he agreed) so I will have two of the same plane. The cost of having 2 complete Contra units is not something that I can afford. I've been thinking about trying a 3-blade prop on my production Allure to see if I could get it close to the way the prototype behaves hence the question. Either way, the Allure will fly at a good speed due to its size but I thought maybe a 3-blade solution may be the answer.
Joe, I appreciate your input as well as ltc for the eCalc reminder. Thanks guys!

Hi Scott,
I think that the 19.5x13 is certainly worth a try for you, on the few flights I have had so far (winter you know!) I really like its speed presentation. So I think if you are going for a similar presentation to the contra it will certainly be closer than most of the 2 blades that I have been flying with, which are generally a little faster, especially on the downhill bits.
