I added flaps to my KR after 500 hrs of flying with no deployable drag, then flew it another 900 hours after the flap installation. My flaps were significantly larger than the "stock" flaps as mine hinged just aft of the rear spar and deployed down to 38°. They were the width of the stub wings. They made a huge difference in the approach and landing of the aircraft. As mentioned by others, initial flap deployment of about 15° caused a nose up pitching moment. More than 15° resulted in more drag than lift, so didn't really cause the plane to pitch any further, but did create a lot more drag. With flaps deployed, my approaches were nose down enough that I always had a good view of the runway. Without flaps, the runway was always hidden under the nose while flying the approach.
My installation could have very easily accommodated the installation of a belly board to actuate with the flaps from the same torque tube had I deemed it necessary.
