103 calcs for stall speed allow you use a CLmax of 2.0 if you have 50%+ flaps. At 450 lbs and a CL = 2.0 you need 115 ft2 of wing...

They have no problem with my flying skills and do want me to play with their balls (that didn't sound right). But they want to make sure...

Thanks Jedi, That just leaves whether I meet the FAR definition of student pilot... I may have to submit a request for a student pilot...

I argued that, technically, I already meet the requirements for the glider rating check ride (PPL and dual and 10+ solo flights) but...

At 27.6 MPH (sea level on std atmosphere) dynamic pressure is 1.95 lb/ft2 so you would need a CL of 2.3 which is a pretty big number!

I'm in the same boat...had a log book from 1975 (when I was 14-15) with 2-33 and 1-26 time. It was hard to pay for those flights mowing...

OK, that made me laugh...Yes it's a very small community and one would think we would all hang around drinking beers and comparing notes...

I was referring the the Klingberg Mk1 crash. I don't know for sure what happened with the Prandtl. I think they just stopped testing...

Interestingly, he has the same complaint about not getting his contacts returned to participate in the man-carrying Prandtl wing tests...

Funny that's one area we discussed a lot when I made the model. I had to make a special "plug-in" to get the "auto-yaw" per his design...

One can choose to model a yawstring but with the steep angle of the windscreen on this one I didn't think it would work well. Plus, Rol...

As Rol Klingberg is wrapping up his build and getting ready to test, and since it's Christmas time, I thought it was a good time to...

As we strive to reduce the amount of foam with thin ribs (which is a good goal for weight savings) it starts to make the skin to foam...

I think that's a good point in that the skin to foam bond's shear strength, and flat-wise tension is what should be tested rather than...

Hi All, I made a video about using OpenVSP's eport to .OBJ as a way to (relatively) quickly get your concept into X-plane to do some...
