If we pull back and push left rudder at the same time, the left ruddervator won't move and the right one will move a lot, moving the tail down and to the right, a left climbing turn.Įlegant, yes? And definitely sexy, as topaz points out. Push left rudder, and the mixer rotates (it appears to be just tubing slid over another tube that is welded to the transverse pivot shaft in the bearing blocks) and the left ruddervator pushrod is pulled forward, angling the left ruddervator down, and the other rod pushes, angling the right side up. Up we go.Īt the bottom you see the rudder pedal cables. The rod that comes in from the bottom of the picture comes from the control stick, and if you pull back on the stick, that rod pushes on the mixer assembly and tips it back, pushing both of the ruddervator rods which push on the control surface bellcranks and both move upward. If you work the rudder pedals, the control stick rod does not move. The mixer tips forward and back in those bearing blocks, and as it does the rudder cable attach points do not move because they're in line with the pivot. Phone number there is 31.You are looking down into the tailcone, and aft. Aircraft Spruce most likely has it, but an expert in this field is Neil Pobaanz of the American Bonanza Society. Thank you for your hard work which the finishing world, and we at, continue to benefit from.

Also, SanChem has a a chrome-free conversion coating for magnesium, SafeGard 3400Mg. Mfg's Manual calls for a mixture of Chromium Trioxide & plaster of Paris solution in water applied to the skin, a kit called Dow19 however I can't find it anywhere and I have to treat these surfaces pronto !Ĭan anyone out there tell me where I might secure this Chromium Trioxide or Chromic Acid (technical-grade) or DOW19 kit ?ĭoes anyone else know of another corrosion inhibiting process that would allow me to paint over it once it's applied ?

There's a fair amount of surface corrosion on the skins and I've sanded the parts with 320 and 400 grit aluminum-oxide but now I need to pickle the skin before I spray the Epoxy Primer & Polyurethane Topcoat. It turns out his Flaps & Ailerons are magnesium. A Beech Bonanza owner asked me to strip & paint his wings from a very early model "V-Tail".
