I followed a couple of threads about taking off using flaps. I experimented with my RV-4 using flaps aligned with fully deflected aileron (15degrees?). I get noticeable shorter take-off run. Is there a down side?
I normally let it fly off at 65 mph and accelerate in ground effect to 100mph before climbing out at 120mph. With flaps I was coming off at 55 and accelerating to around 80 in ground effect before bring the flaps up and continuing in ground effect 'til 100 then climbing out at 120.
This is a RV-4, IO360 with Hertzel CS.
