Question - rudder flutter ?
You'll get one of those thngs out of anywhere, but if the field is, say,
400 yards or more, you'll get an acrosport in and out of it easily. Even
shorter if ou're sharp.
Suffice to say I'm pretty excited about the AcroSport, it's
performance, and how you can fly it. Plus, it's a fabric covered
biplane. How kick azz is that? Well, very.
It's a longer term project though.
I wonder if you could use a Mazda 13B -- should fit in the weight / hp
range. Not many moving parts to break, either. Hmm. Don't know if
anybody's done aerobatics with a 13B though.
I want to give a shot at plans building the 701. There's a nice set of
videos that show quite a bit of the 701 construction sequence from
those Canadian guys at Can Zac. I might buy some of it as a kit to
save some time though.
I suppose these thoughts are way off topic. To bring it back: I know
of only one Zenith STOL that had structural failure probably due to
flutter as a result of exceeding Vne: somebody dived an 801 at the
ground and apprently ripped the wings off on the way down. NTSB report
says both pilot and passenger had a good bit of THC in their blood ...
only fatalities I know of in the STOL series from Zenith and clearly
pilot caused.
