well I am sure none of you are thinking exactly of what I have in mind, there should be very little efficency loss, If I tell you the other good thing it may give it away, but it is something that could gain back the little efficency lost, and yeah its be perfect for that plane, which is an awesome plane, If it works Id probablly build one at cost for you for that project, I just can't give to much away, cuz if all of a sudden people stop looking down on this idea then everyone and there mom will be building one to pitch to a company, Like I said it will be flying by mid august on a slowstick testbed or on one of my 3-D foamies, although it serves no benefit to 3-D but if I dont have to buy and set up another plane then it will be the best way to go, but either way it will lift off by mid august, at that time I will decide what I am going to do about protecting the rights or maybe through use of a non-diclosure clause or contract get it to a company, see where it goes, I bet the first guy to make a VPP setup was looked at as a fool, till people saw it in action an realized it, so like I said mid august, but the most you'll get it a picture of it that only shows the twin props, I"ll block off the adapter in the pics, maybe if I can get a way of doing it I'll get a vid. It's gonna be cool as hell if it works out as good as I think it will...I am suprised more people arnt interested in this idea...
