Guys with speed brakes. Do you always do a full deployment of your brake or do partial deployment as needed? ?I have internal limit switches in my actuator. So all I need is a on on switch. ?Or if I want to stop in the middle. ?I would need a on off on. This would be on my ?stick grip.?
Paul Visk?Belleville Il hello618-406-4705 Oscar did the calculations for the FLAPS on my KR with full flaps deployed to 37?, which is likely a little more area than most belly boards, but similar in loads.? The load calculation gave me a safe speed for full flaps of 100 mph IAS with a 10% gust load factor.? I have had partial flaps out at much higher speeds, but I always keep in mind that the calculation for full deployment was for 100 mph, so marked the ASI and fly the plane accordingly.? I don't think the limiting factor was the flap mounts so much as the strength of the flap around where the actuator arm mounts to the flaps.? I ended up using the flap actuator sold by Vans for an RV.? It is larger and heavier than what I needed, but at the time that I did this installation the cheap Chinese electronics weren't so readily available to us and I was running into a lot of difficulties trying to procure the actuator I wanted. FWIW, both my ailerons and flaps are mounted with countersunk #8 machine screws into self locking nutplates floxed to the back side of the false spar.? One thing that I almost always do with self locking nutplates is to run a tap through them before?
