    Hello Fred,
    could you let me know more about the valve that you used to select left/right braking please, is it a solenoid valve or just manual.

    The brakes caught me out the other day on my Avid.
    A thermal caught me as I touched down and kinked the plane a little to the left, full right rudder applied but I kept going left!! Unfortunately I went off my airstrip onto some rough ground so a wingtip went down and the flaperon touched the ground. The wing is now stripped of covering and I'm doing the repairs.
    Not a ground loop as I basically went straight but at 20 degrees to the strip.
    I don't have much time on the Avid but have about 700 tailwheel hours and am in current practice with a Chipmunk so my feet are not dead.
    My analysis is that full right rudder brings the left brake forward and unless one has the presence of mind to lift the left foot then the brake is applied. As the aircraft slows the rudder becomes less effective but the brake doesn't!!
    Basically the brake pedal geometry sucks.
    I am thinking that valves on the pedals and a lever on the stick would give good differential braking and be similar to the setup on the Chipmunk.

    If you don’t trust plastic (polymers) then the files could be used to CNC machine the parts from aluminium.

    OK NorthIdahoAvidFlyer it's raining here so I can't go flying so I've added a version with 5 positions which should result in 3 degree of flap per.

    Possible NorthIdahoAvidFlyer, if I get a moment I'll do it. No promises though, I'm a bit busy having fun

    3D Printed Flap Detent
    Here are the files required to print the flap detent:
    Avid Flap Detent.stl          1 reqd.
    Avid Flap Handle.stl         1 reqd.   
    Avid Flap Cap Piece.stl   1 reqd.  
    Printed with 20% Carbon Fibre filled PETG filament, 0.2mm layers, 5 perimeters, 5 top and bottom layers, 25% fill. Handle will probably require 5mm brim for printing.
    A 3/8" diameter x 1"  spring is required, 8 x 3mm diameter x 30mm cap head screws and nylon nuts also required.
    Flap system may require adjustment to give zero degrees on the fully forward detent, the fully aft detent should give 15 degrees.

    As CloudDancer shows there are plenty of outfits that will print stuff for you, another is 3D Hubs. I would have to charge about £50 (Sterling) plus shipping to cover my time and materials. 
    I will post the files into the Files section with some notes later today.

    Flap Lever
    Though you guys might be interested in my take on a flap lever detent, it's 3D printed from carbon fibre re-enforced polymer.
    If anyone would like the files to print one let me know.

    She Flies, follow this link for the video:
    No snags and no adjustments required but I am having trouble restarting the 582 when hot, plugs are getting wetted. Any tips on shutdown procedure would be welcome.

    Avid Speedwing First Flights
    These are a couple of articles from Graham Laucht's UKAVID newsletters from 1993. Very useful if you are about to fly a Speedwing for the first time.

    The Aerobat wing is the same as the Speedwing but with thicker wall tube spars and larger diameter lift struts. Here in the United Kingdom the gross weight is 911 lbs which on the Aerobat can be increased to 1020 lbs if stiffeners are fitted to horizontal and vertical tail surfaces.

    Fred, you would be more than welcome to visit us at Fen End Farm and have a flight in our Chipmunk, we are on the aviation charts and Skydemon. BTW thanks for the videos, very inspirational esp. as I also ski.
    Actually the wording of the LAA requirement is that I get at least an hour's flying experience in another Avid or Kitfox before I test fly mine. Just checked my logbook and I see that I already have 35mins in an Avid Speedwing back in 1992!!!
