FredStork added a topic in Avidfoxflyers General Hangar
Bungee strengthI’m looking for the strength/force of the standard bungee setup. 90” loop to loop, 7 wraps of type I 3/8” shock cord (aircraft spruce ref. 06-12400). I.e. what is the force required to stretch it to the maximum expected extension...
Does anyone know, or know how to calculate it? (Asking before building a rig to measure it...)

FredStork added a post in a topic First Avid Flyer fly-in in France after deconfinement...
Pascal,
thank you! This is the best kind of feedback and encouragement I can get for my videos.
I have a little gift for your son (and his father) that I hope can make him make some sweet dreams. It is the unlisted film about a cross France flight I made with my 10 year old son a few years ago

FredStork added a post in a topic Getting close for an engine choice
Matt,
Simonini Victor 2 update
I'm closing in on 200 hours on my 92hp Simonini Victor 2 - without any issues. I have burnt one ignition coli but they are the same on Rotax so I cannot really blame Simonini for that.
Plenty of power with an unbeatable power/weight ratio. Consumption like a 80/100 hp 912 and 20kg less...
The only negative thing about this engine is low rev vibrations. I good carburetor synchronization helps but it is never super smooth in low rev.
the 92hp version is no longer sold, they now start at 100hp and with a more Rotax like single exhaust. You miss a few hp not having the twin tuned pipes but starting with 100 you still have more than you ever need. And it is much easier to install compared to the twin pipes that goes between the landing gear...
You can see it fly here: https://www.youtube.com/user/fredstork

FredStork added a post in a topic Interior Seat Cover
If you still have the old seat cover you can use it as a pattern and do a new one yourself. Or have the friend with the sawing machine do it for you, it is not that hard.

FredStork added a post in a topic Not a cowboy...
Chris,
I have got the same comments from over seas friends coming here, the sky is empty! And I can confirm, I can fly cross France in the middle of the summers and, when not in the direct vicinity of an airport, not see another plane all day. I'm actually worried about thinking I'm all alone and be less vigilant...
A lot of pilots do 30 minutes local flights around the home airfield and many don't fly at all... I have visited heaps of empty airfields on my trips... sometimes I call in advance and then I normally get a welcoming committee...
You are right, I'm a lucky man!

FredStork added a post in a topic Sold!! Avid Snow Skis
- but as size matters make sure to get the long wheel axis kit that is required for mounting them. If they don’t exist I’ll be happy to measure and document mines, they should be fairly easy to have machined...

FredStork added a post in a topic plywood seat truss reinforcement
The »horizontal » chock cord will not, and is not intended to, replace a broken normal bungee. IT WILL NOT ALONE HOLD YOU OFF THE GROUND. But it will very efficiently add deflection resistance, almost noting at normal « soft » landing but exponentially the more deflection there is. I have never heard about broken bungees - but, according to a friend, hard landing do occur.... and I, I mean my friend, has not had a pro strike even at hard landing that with the “safety wire “ would have broken the seat truss of my, I mean his, plane.
The stiffer chock cord the better.

Reinforcement of the seat truss is good, cutting the damn guillotine, sorry "safety", wire is better...
Been there, done that, broke that...
Replace it with an horizontal chock cord:

FredStork added a post in a topic Avid Flyer Heavy Hauler STOL. flaperon extension speed
The flaps is like the doors, not over 100 km/h (60 mph). 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.

FredStork added a post in a topic Strip it the rest of the way down?
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

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...

FredStork added a post in a topic Book Recommendations?
Another "must read" is obviously Chuck Yeager's "An Autobiography"
No description needed... The language is colorful and the story amazing.
Amazon US https://www.amazon.com/Yeager-Autobiography-Chuck/dp/0553256742/ref=tmm_pap_swatch_0?_encoding=UTF8&qid=1568910855&sr=8-1
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

FredStork added a post in a topic Book Recommendations?
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.
Amazon US link: https://www.amazon.com/gp/product/0786883154/ref=dbs_a_def_rwt_bibl_vppi_i0
I hope this string will be long!

FredStork added a post in a topic what is a bush pilot?
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?

FredStork added a post in a topic Bush gear topic reopened
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...).

FredStork added a post in a topic Done getting bit in the ASS by toe brakes
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.

FredStork added a post in a topic Done getting bit in the ASS by toe brakes
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!
