>2) What effect would it have if I forgot to raise it while doing touch and goes? Almost unnoticeable since,I'm getting about 130 hp on takeoff from my Subie EJ-22 with PSRU. It would probably have a bigger effect if I was using a smaller engine. >3) What effect would it have in cruise flight? It cost me 10 mph in speed and my water temp goes up about 10 degrees F. >RV ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
RV, What size is your speed brake and what angle will it deploy to? Mine is 9" X 30" and deploys to very near 90 degrees. With the modest effect your brake seems to have on your climb and cruise I wondering just how much drag you are getting on landings. Any noticable differance? Mine will knock 10 mph off my approach speed and requires me to carry a bit of power to keep from dropping like a rock. I'm getting an additional 300+ fpm decent rate with the brake out.
