1. ### Modern day "motorcycle of the air" aircraft class?

Maybe a seat that slides to either side for roll control (ala early wright bros) and fore/aft for pitch; and the handlebars provide the fixed point for the pilot to steady himself and leverage his weight/seat around. Perhaps the bars steer a little for yaw, or just use foot controls for rudder...
2. ### Modern day "motorcycle of the air" aircraft class?

I think the inspiration for a flying motorcycle has been around for a while. Here are a couple more that had trouble with too little wing area. Still it keeps the juices flowing.

Here are some real life examples :) grabbed from Motorcycle Art - webBikeWorld
4. ### Echo (Ultralight Self-Launching Sailplane)

Like an X-29 but slower A couple of posts ago I decided to look into an asymmetric layup for the wing skins in order to generate some bending-torsion coupling that would give my wing some wash-out under load DESPITE having forward sweep and a shear center aft of the center of pressure. This...
5. ### What do you think about "e-soaring"?

That was a nice video to watch...It seems he wasn't concerned about the trim drag of the high mounted prop, but just the airflow at the prop. Maybe I shouldn't care so much and press on.
6. ### What do you think about "e-soaring"?

I'm still thinking about one vs two motor pods. With one (my current plan), I need (analytically) over 5 degrees of elevator to trim out the forward pitching moment (plus a couple of degrees of rudder). That extra trim drag could be avoided/reduced with two motor pods, but then I get more...
7. ### What do you think about "e-soaring"?

At least the solar panels are in the wing, so a second set of wings can use the same spar design (molds) for the solar wings model. The weight won't add to spar loads except at landing, but my caps are over designed for negative g. Just need to check the fuselage and landing gear with the extra...

13. ### Echo (Ultralight Self-Launching Sailplane)

Stall Behavior (revisited) I was thinking about the local lift coefficient approach I’d used to satisfy myself I would have reasonable stall behavior. It revolved around having somewhat lower local lift coefficient requirements at the ailerons, and similarity with other sailplanes. I started to...
14. ### Echo (Ultralight Self-Launching Sailplane)

Wing Structure as a Beam (part 3). I was getting ahead of my posts here, and as sometimes happens I got “wrapped around the axle”. Since writing about it seems to help me re-focus, I thought I’d catch you up. Wing beam FEM : So I was attempting to predict wing bending and torsion of my...
15. ### % loss of hp / 1,000-ft ?

I think it's approximated like this: HP Loss = (elevation x 0.03 x horsepower @ sea level)/1000 I don't think being a 2 stroke or four stroke will make a difference.
