REFLECTOR: PITCH & ROLL TRIM

[Brian Michalk]

How about using the sparrow strainer as a trim tab?

  Be careful Tom, at least with the elevator trim- it won't work like you
think- the "elevator" on a canard is really a fowler flap and won't take
trim like a normal elevator would- I would guess that the trim tab would
need to be about 30% the size of the elevator to get the effect that you
want, and then it would destroy the effect that the flap produces-  The trim
tabs should work on the ailerons though......

    I like most everything about the Velocity design except for the pitch
and roll trim.  So I am finally doing something about it.  I am installing
tiny trim servos in the elevator and one aileron and outfitting them with
piano hinged trim tabs.  The wires will be run inside the torque tubes.  I
am happy to be eliminating that clunky linear activator and the cumbersome
fiberglass trim spring on the canard and the string & spring roll trim.



    Anyone else ever do this?



    BTW – I have forgotten to post the paint designs I promised 
 but it’s
been difficult to get my graphic artist to send me the digitals.  All I have
now are large print-outs.  They should be coming soon.
