Re: Canard mounting

I have the female templates cut out for BL48.8 and a Super Level
(digital) that seemed to work the best for me. Could bring them if needed.

Thanks Paul. I haven't moved the CG way back and tried to pitch buck. May
try that soon. I really wonder if that t-tail is doing something to
pitch buck!

Yes, the Soob is heavier than the VW but not by much. My Q didn't pitch
buck with the Revmaster either.

The best part of this characteristic is that I don't get bored with my
landings!! :-)

Anybody out there have the tools necessary to accurately measure the angle
between the wing and canard? If so, bring them to Ottawa!

I think my canard is mounted slightly "down" as well (same
problem - I don't
have the tools to measure it accurately!). I have to keep the ailerons
reflexed up slightly to keep it straight and level. I've got ~815 hours
now, so I don't see the need to change the incidence of the canard at
point. It does pitch buck - depending on the weight and reflexor
but I suspect it is costing me some speed at the top end (especially at
lighter weights).

I don't know if the different airfoil on your canard might also change
characteristics from Larry, Sam or myself. Certainly the T-tail and
reflexor will change things.

Is the Subaru heavier than the Revmaster? More weight on the
nose may have
just made a marginal problem much more noticeable.

Sounds like I better explain myself so I don't sound like I'm
dreaming up
some hair brained idea!!

My Q2 has over 400 hours. It flew almost all that time with a
flying with the Subaru. It flies pretty well. However; it does not
buck. Rather, it starts downhill (mushes) at 85mph and full
down elevator.
The down elevator stop is greater than the plans (first thing I tried
ago). I must be over the numbers at 90mph and a little power
if I hope to
land (otherwise there is no elevator authority). I have tufts on the
elevator (canard) and they exhibit some interesting behavior
during climb.
If I use the elevator to pitch for climb the tufts start going
wild (side
side, up, and occasionally FORWARD) when deflected more than 1/4" -
(haven't measured it exactly but it isn't much). To avoid this I have
started using my reflexor and t-tail to pitch for climb and keep the
elevator "in-trail". I don't have a VSI so I cannot accurately
there is any difference in rate of climb (between the two
methods of pitch
change). I am currently flying at the forward end of the CG
limit but I am
within the limits. My Q1 pitch bucks normally so I am familiar
with what
feels like. This problem has never been a big deal but am becoming
interested in at least knowing what the problem is even if I
don't fix it.

I made a set of "outside" airfoil templates using the core cutting
(the BL 48.8 template for wing and BL50 for canard). I transferred
water line from the template. My new templates match the airfoil
well. I raised the tail until the main wing was level and then
checked the
canard, it was slightly nose down. I didn't measure how much
as I didn't
have a digital level and couldn't remember how without one (no need to
up instructions - I have them, just need to dig them out). The
intent of my question was to find out if a Q2 would even fly with a
down canard and if so, would it behave like mine does. Sam, mentions
needing lots of nose up trim. I don't need much but I do have a t-tail
could be masking my problem.

Point of clarification Jon, please. Are you asking what
would happen if
the AOA of the canard was reduced relative to the AOA of the
wing? If so,
by how much?

Hi all,

A not so hypothetical question: How would a Q2 act in the air if
the canard
(WL) were mounted nose down relative to the wing (WL)?
