    Ther flaps is like the doors, not over 100 km/h. But in any case, the faster you fly the less flaps you want - you can even gain some speed with negative flaps, but be careful as this can be a dangerous area.

    Had the same hesitation some years ago, the more I striped it down the more rust I found. Had all metal sand basted and powder coated. Covered with Oratex UL600.
    Take a look at my blog, this link is pre-selecting the rebuild posts the Avid Flyer 
    This is from the covered parts of the tail plane while free tubes didn't look any worse than yours. A critical area, difficult to inspect, is the tail. Whatever you do, uncover it to find out...

    Another "must read" is obviously Chuck Yeager's "An Autobiography"
    No description needed... The language is colorful and the story amazing.

    Amazon US
    and when you have read Yeager's book and seen The Right Stuff one more time you will appreciate The Happy Bottoms Riding Club - The life and times of Pancho Barnes

    Great idea!
    I have a rather large collection aviation books and I'm always looking for good additions. 
    One book I read recently and really, really liked was Flight of passage by Rinker Buck. Very much in the spirit of this group and an amazing true adventure by to young boys at a time when everything was possible...

    Description from Amazon:
    Writer Rinker Buck looks back more than 30 years to a summer when he and his brother, at ages 15 and 17 respectively, became the youngest duo to fly across America, from New Jersey to California. Having grown up in an aviation family, the two boys bought an old Piper Cub, restored it themselves, and set out on the grand journey. Buck is a great storyteller, and once you get airborne with the boys you find yourself absorbed in a story of adventure and family drama. And Flight of Passage is also an affecting look back to the summer of 1966, when the times seemed much less cynical and adventures much more enjoyable.

    I hope this string will be long!

    Feel no shame... Regardless of what "they", maybe incorrectly, call themselves I think they are doing more to raise interest and awareness for a niche of aviation than anyone else. Our niche with relatively low cost, easy access, slow taildragger aircraft that looks like the planes in our childhood dreams.
    I am personally amazed by how many pilots, and wannabee pilots, have contacted me for information and advice on the Avid Flyer after having seen my not very spectacular films - and I only have 430 subscribers so my films don't easily pop up in the suggested film list...

    Fake branding?
    I'm not sure if I'm reading this right... is the problem that those YouTube pilots are calling them selves "bush pilots" and that is offending those who are real bush pilots?

    I think the basic approach is correct but to get the geometry right we should look at Just Aircraft and their Highlander. 

    You could even go all the way up to the wing (and add a cross bar...).

    Yes, any valve that can do open "only left", "only right" and "both" will do. If it also have all "off" it will do parking brake as well.

    The Avid is good at crosswinds landings. If you would need both rudder and brakes to keep straight you could probably do a really short cross the runway landing instead. Being precise with rudder and differential brakes is very difficult. 
    The ideal theoretical solution is differential brakes on the pedals and master on the stick - I, however, never got it to work correctly due to the difficulty is getting a good geometry on the pedal/cylinder.

    2 manual valves, in the middle position they are both half open, when one is closed the other is fully open as they are mounted mirrored to each other

    they are operated with a knob close to the throttle (that I have on my left hand side exactly where my left hand falls)

    and I have one single valve, placed before the double valve, for parking brake. Works great...
     it is the same kind of valve as the others.
    I hope this helps!

    ...but remember, Oratex is only for those who are not into sniffing dope and thinner and only want to spend one weekend from ready to cover to ready to fly...

    I have tried all versions by now: pure toe brakes, mono hand brake on the stick, double hand brakes on the stick, toe brakes coupled with mono hand brake (this was the theoretically most pleasing solution) and finally mono hand brake on the stick and a switch for braking on only one side. 
    I agree that ground loops should be due to bad rudder action and that differential brakes are there to save the situation. But I find the reality being the opposite. It is very hard to be brake in a “creative “ fashion with the toe brakes while still working the rudder. Some can do it, but most will fail when they are half way into a ground loop. And while it can happen to anyone it is less frequent for the experts...
    This is why I, not an expert, prefer having easy access to powerful, while still easy to dose, equal braking. My solution is a main (motorcycle) brake handle on the stick. Moderate brake an rudder still allows for fairly precise maneuvers and I can brake hard when needed without the risk of being to hard (ground loop...) on one side. And, for tight situations I have a switch that direct all the brake power (fluid) to only one side making it easy to turn around one wheel (a flashing light tells me the switch is engaged to avoid leaving it there for landing...)

  14. FredStork added a post in a topic Weak point in the Kitfox tailwheel spring attachment design   

    That hard Maule tailewheel is a killer for the tailspring, it provided no damping what so ever and it is heavy.
    While keeping the mechanism intact (I belong to the minority actually finding it good...) I replaced just the solid wheel with a pneumatic wheel 2 years ago. I get much less vibration fron the tail and it is more comfortable...
    I wrote an article about it on my blog
