REFLECTOR: barn door speed brake

[Terry Miles]

Craig,
What would you guess your extention angle to be?  I could use the 6" but
I was fearful of the almost 90 angle I had when I did that, and also
coupled with the fact that my jackscrew attach point on the board was
forward of the mid point in the board.  I thought about gouging two
channels lengthwise and imbedding some of that "horsehair" stuff, but I
went w/ a 4" jackscrew instead.  I get just over 45 degrees now.   Also
we too beefed the floor as you did w/ triax.
Thanks
Terry

We built a XL-5 FG and you can stay with the 6 inch jackscrew you just
need to move the upper attach point forward (might not be possible with
RG).  It does require the jackscrew to rotate so the hole in the
fuselage is now a slow rather than a hole.  I do remember us having
issues with where the aileron bell-crank for the drop down went, so
watch for that also.
