PCM lock out servo mvt

[Rcmaster199 at aol.com]

I have tried the "Dethermalizer" command on a Funtana 90. This model is set  
up for extreme flight and has 50 degrees up elevator. 
 
Essentially I put the plane in a Harrier and tried controlling the  
oscillations in the usual way. Then I decide to not use rudder and aileron, only  
elevator. Oddly enough, the oscillations didn't really get that much worse and  the 
model didn't flip on its back, an unexpected result. It still  oscillates 
hard at only 50 degrees of throw and it would likely catch a wing tip  if brought 
down that way.
 
Maybe what is really needed for real dethermalized flight is elevator  
command at closer to 90 degrees or possibly having the whole stabilizer flip up.  
Kinda what Burt Rutan's team did with their re-entry spacecraft.

Dean,  Great idea ! Some airplanes are more stable in inverted Elevator than  
upright. All of those who have enough elevator to Elevator need to try it  
and report. Maybe no more crashes <BG>!!!!        Nat
