Increased drag alone would not cause the nose to drop if one replaced the
thrust to counter the additional drag, since there would be no change in
angle of attack. The nose down tendency is due to a change in the position
of the Center of Pressure (lift) relative to the Center of Gravity.

The speedbrake needs to be behind the center of gravity. The further it is
from the cg, the more it will affect pitch, etc. It needs to be mounted

Does your speed brake result in a greater nose down attitude than just using
flaps alone? I guess it depends on just where it is hinged. Does it contribute
to lift/stall speed at all?

I don't have flaps installed
My question is...what thickness 6061-T6 aluminum should I use? The only

I got in some flight testing today and also some crosswind TO & L
practice. Eight to twelve mph at 60 to 90 degrees to the runway.
The KR seems to handle it better than the pilot. It did everything
I asked it to do without hesitation.
An eight direction speed run averaged out to 156 statute mp
