REFLECTOR: Canard cover

[Pat Shea]

Keith,

I do have the usual arrangement you described & that
same thought ran thru my head. If it is canard flex,
then it should also be happening at low airspeed. It's
possible that it does but since I'm still breaking in
my engine, I haven't done much flying in the lower
airspeed range. I can also check the effects of
G-loading as well. Clearly I haven't gathered enough
data yet on this - I'll report back.   

If the bulging is only caused by high airspeed, then
it is probably just (low) pressure and an additional
fastener or two should do the trick.
