Of course there is some tricky alignment and coordination required to attach the D tube to the framework, but it is doable. |

Kent, yes, the D tube + sunlit ribs would be lovely. I might save that structure for an E-powered wing for summer flat-field thermaling, but it will have to wait for shop time when I'm not burning up my budget on heating. A rocket stove mass heater is in the works at the moment, burning up my time.
I want to get a quickie in the air to compare to that lightweight, fast-building, sweet-flying, bounces-off-rocks, 54" Moth. My buddy Chris is a master plank-tuner, but the rest of us need something with a little less pitch sensitivity...if it will fly with the Moth. The old Talus is 59" span, and is close to the Moth's wing loading, but it's a crude ship, with a rough airfoil, no twist, and it's getting pretty fuzzy on all the edges. Still snowing... gonna be some time before flying happens again. |

With the hyper stall option for landings, I see no need for crow. Just give me full length elevons.

Can't see the plane? It's a wide angle lens. The landing was 30' away.
Try setting youtube settings to 1440p and go full screen. The raw video is more clear than the youtube version. You might be able to download it at this link It is not stable during the hyper stall, so you are throwing the stick all around just to keep the nose towards the ocean. Currently this plane is way out of tune. It turns right instantly and barely turns left. I normally do not intentionally use diff. aileron on a plank. I do use down elevator during the inverted part though, which may affect something. The elevons are full span now. I don't think that it would hyper stall with the partial span elevons. |

I don't think that I will get my certificate for consecutive axials rolls any time soon. The big air in Los Banos is the perfect place to practice. Don't forget to set your youtube resolution to 1440p.
I'm mighty picky about the landing attempts. Just as easy to fly through and go around again, unlike every thing else in life.
Here's 8 minutes of your life you can never get back again..............the warm up laps.

Correction..............This is big air............and gusty too.
The unballasted Plank 101 handled the big air pretty well.
