Next revolution in pattern planes?

[Karl G. Mueller]

Matt,

You were close. The year was 1977 and the location was Springfield, Ohio.
That was the year a twister went through the competition site the night before
and tore down, among other things, one of the tents that was used to store 
the models in. It was quite a mess, but the contest went ahead as scheduled.

  Anhedral stabs are affected by crosswind more than flat stabs. At least for the kind of flying we demand. The Prettner Curare design, World Champ around 1976 or so, introduced the feature to models. By virtue of its being World Champion model, everybody copied it. Sort of the way fixed gear took over from retracts, except fixed gear have persisted far longer and serve the intended purpose well. 

  Curares and other anhedral stab designs flew well into the 80's but eventually the fad died down. 

  Naruke san is possibly trying to cure some aerodynamic inadequacy by employing the feature again. Or maybe just likes the look. It does look Kool as hell. I doubt that this is a revolution though; more like evolution....in reverse

    Beautiful plane, but planform is BTDT, remember Hanno??? And the Bridi UFO?  And others.  The anhedral stab really introduce bizarre characteristics, if I recall.  It was abandoned as an "innovation" about as fast as *somebody's* "Split Rudder "airbrake"....

    Man, we are O-L-D...
