Chris,   I'm going to re-just my flaps to -10 reflex and see what happens. What would you guess the measurement is up from the trailing edge of the faired in position?

            Thanks for all your work. Do you need a small tail 360 for more testing?

So I happened to be looking for something unrelated in the FB manual and came across this on page 10-24:

 

"Lancair flaps are full electric actuated.  They are designed to run from +45 down to -10 up (reflex).  Note that the 'faired in position' for flaps is actually a -7 deg reflex position. ....."

 

My standard build manual is in storage so I could not compare.  It would appear the intent was to be able to go to -10 degrees after all.

Chris,

today I made a picture during Cruise with Autopilot at 7500ft with following configuration:

770 kg  40l in header, 20l in each wing (80l total), 75kg and 83kg for pilot and co.

Flap was on 7° reflex  CG 26,20"  

My design CG is 22,8  -  30,3 from firewall back,  horizontal was installed - 0.6°

So it looks like if I would add more reflex than 7°, I would need more down elevator.

So the gain with the higher reflex would be lost with the down elevator....
