landing distance mmn speed control is a very good idea as is flaps as is brakes tri gear or taildragger i wonder i can get it down to about 600ft but for ,margins need more a belly board can really help phill

The lighter weight and additional hp of the J3300 should improve the takeoff performance on any kind of runway surface. Landing distance can be controlled with the use of flaps or speed brakes. I can land my "heavy" KR in 1500 feet on a hard surface with the use of a speed brake and airspeed control. I've never heard of any control surface attachment or engine mount problems on a KR other than in a crash and consider both to be quite adequate to the 200 mph Vne speed. I seem to recall Richard Shirley is running a J3300 in his KR1 without any problems. Just my opinion and not very scientific. Go with whatever you are comfortable with.
