Just Fly it

Dynamic 160


It was great seeing You and your Plane yesterday Joe. Good decision not to fly. We probably could have flown it about noon. But the sun would have been another problem. It wont be long now.

I suggest banging out a 80-100 inch Dynamic to fly when conditions aren't so WR if ya know what I mean,,,save it for it's time.

Impressive stuff.Look forward to hearing about its first flight when the time comes.Looking at the photos it appears there is only the carbon "tongue" and one wing bolt holding the wing to the fuz.Is that correct?I guess the structure would fail first rather than a high tensile bolt.Just curious.

6 or 7 servos survived. I used all new servos in the wing. The two elevator servos were still in good shape and still glued together and fit nicely into the new fuse.

Im pretty sure the tongue can take the loads. I hope anyway. We ran some calcs. The numbers checked out. It should be safe. I always worry about that myself.

Hi Joe, Love your work! Quick question, and I'm sure this must have been previously discussed with your collegues, would a 2-piece elevator have helped with redundancy in light of how the previous version met with it's demise? Or is the single elevator needed for rigidity at the speeds required? I know from my pylon racing and combat flying that most planes are controllable with half an elevator or tailplane missing or flopping around. Then you could run 2 receivers one to each half for even more redundancy.

That would be good. It may come into play soon. For the moment my goal is to make my current system work.

any chance a full flying tail with bell cranks for more mechanical advantage would handle 400mph?

More linkage = more play
More play = more flutter
More flutter = more destruction

Secondly, the forces on a flying stab would be huge and the play would be exaggerated by the large control surface.

Actually a full flying stab can be very good for DS. It does not change the airfoil and therefore you dont have any unwanted forces/turbulence.
This is why on my DS Kobra the wing/tail decalage is a little high (T-tail with flipper) and CG is a little in front to my liking. On the frontside I fly with a lot of down. When reaching 150-200mph I am almost at neutral elevator. I suspect I will fly 300mph with neutral and as clean elevator I can get.

But off course linkage/rods/etc. on a full flying stab has to be rigid and scaled to cope with the forces.
