You could say that. What caused all this was just my asking the wrong question in the first place. I knew we were limited in prop size. Period. Doesn't matter what anyone thinks about the prop size. We were going electric, which the plans allows for. However, others who have built and flown this glider with the stock setup complained of it being way under powered. Just barely would fly. With brushless setups you go from reasonable prices to ungodly in a short jump! Motors jump in price, batteries go way high and ESCs skyrocket when you get past the $100 range! We wanted a power setup that would provide what we wanted without going into the "power not needed" range. I had one calculation that said this prop would provide the thrust needed, but, would have to be turning at 15,000 rpm.

Now. I had heard in several places statements like "you need a gear setup with a larger prop because if you just keep speeding the prop you reach a point where it's just beating the air and adding nothing.

So...... I was looking at it wrong and was asking if there was a speed at which point spinning a prop any faster would do nothing extra. I didn't know if this prop would work at that rpm......or, if we were going to have to deal with an underpowered plane or completely rebuild the fuse. The latter was not going to happen.

There. All of this because I wanted to know if that prop would work ok at that rpm.
That is really all I wanted to know and the question I asked was just for my information, about the speed where increasing would do no good.

If the prop would work at that rpm then we had a power plant at a reasonable cost that would do the job.

It flies fine. Bad ESC caused me problems forcing me to cut the maiden flight short, because the nice winds had suddenly gone crazy and I couldn't keep the throttle open where I needed it. It was being carried toward trees. I brought it down quickly, wind gusted forcing the nose up and I failed to respond quick enough. It tip stalled and caught on one wing as it hit. There was no damage at all. Just pride. I am waiting for a different ESC to try it one more time, in a more open space, before I put the trim on the glider and send it to my friend.

There is a couple photos of it in its skeleton form in my gallery.
