  1. On my KF4 with 503 Rotax , I installed matco  6" wheels and brakes and 8:00-6 tires... THe brakes barely worked. I added another set of calipers to each wheel so now I have two brake calipers on each wheel and the brakes are better. I can hold the left brake and pivot around but i HAVE TO  push prett y hard on the pedal....I tried conditioining the brake pads and that helped a little... 
     
    The second issue is I flew the plane the other day and at 6000 rpm, 2 blade WD prop = about 80. 
    I installed vgs on the wing and a new WD taper blade prop, same 72" diameter... now I cruise 85 at 6000 rpm but the nose wants to rise and the flap handle is all the way down....
    IS it ok to adjust the flap handle to go lower to be able to trim the plane? Are the VGs makeing the wing create more lift or is it just the extra 5mph speed????its got me stumped.
    IT will stall about 35 flaps up and I saw speeds as low at 30 flaps down but that was about it... the air was so rough again it was hard to get accurate speeds but they do seem to help.
    I have grove gear and it sits too low....I can tell because when the plane comes off the ground it jumps up about 30 feet in the air like a rocket... I just cant get any more angle.... should have orderd 2" longer gear legs. Or I can insall bigger tires I guess....
