My First Peanut Scale Build: BD-4 by Bill Hannan

[Prosper]

. . .but in what part of the flight envelope does it need 'that' much tailplane/elevator movement?

Hi Nigel, that deflection looks much like (from memory) the up-travel of a Piper 'stabilator' as on Cherokee or Seneca etc. I just looked online - the PA28 has 18° up, but only 2deg down. The BD-4 looks as if it might have a shorter tail moment than the PA28, too.

Neat build, Markus, I'm following.
