    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!!!

    Thanks for your encouragement akflyer, I guess if all else fails I'll have to check out the cost of flights to Alaska:-)

    New build flight test HELP
    Well after 25 years I finally finished building my mk3.25 Avid Speedwing, those in the UK may have read about it in the LAA magazine.
    The LAA have said I can do the test flying myself but first I have to get an hour in a similar type. Basically this means a 2-stroke powered Avid or Kitfox. Not many around these days so I am a bit stuck..
    If anyone can help please let me know, I don’t need to be P1 just do some handling and follow thoughts from the passenger seat.
    I am based in the UK and my airstrip is Fen End Farm 8 nm north of Cambridge, so if you want a new destination with accommodation if required you could come to me or I can fly to you in our Chipmunk. Either way you can get some time in a Chipmunk as a thank you..
