  3. zadwit added a post in a topic I have always wondered " what if "   

    Back in the 60s in Alaska bungees cord was made from some kind of natural rubber.. It still was elastice at -40.. Starting around 1968 , the MFg. changed the composition of the bungee(shock cord) and if stretched in cold weather, would take a "set" and not pull the toe of the ski up after takeoff...  That old natural rubber shock cord I am not sure you can get it any more.. THis is one reason lots of folks went to using springs instead of shock cords.....
     
    WHen the plane is sitting 3 point, the front bungees is stretched a lot... and if it is 0 or colder, will likely take a set......

    Because everything cost more and more , I see 3 planes stuffed in a hangar and each owner shares the cost... If I was younger, Id find 2 or 3 buddies and buy this jig, then build 3 maybe 4 airplanes. ONe for each owner and since you have multiple owners, extra hands come in handy especially when pulling the fuselage out of the jig.. THis jig looks to me like it build a tandem seat tail dragger with STOL characteristics and folding wings.... It has heavier tubes in some load bearing areas so a larger engine could be installed. There is no substitute for wing area and horsepower... Kelly prototype is in the photos.. this fuselage was built in that jig..., it has tall heavy duty gear to get more angle of attack on the wing for shorter takeoffs. I personally dont know anything about the Yamaha 4 cylinder engine however I have seen a few videos of them flying and there performance is eye watering to say the least, what a way to hot rod a plane...and that engine comes from a Yamaha RX1 snowmachine and have a proven record of reliability..
    Kellys shop it stuffed full of  projects plus he works full times, like I said he has 200 yrs worth of projects...I told him Id post it on here to see if anyone or group is interested in it..

    Fuselage jig for sale
    I ventured over to the west side of the Cascades and while over there stopped by to see Kelly QUick. He has 200 yrs worth of projects and asked me if I was interested in buying his fuselage jig. It is like a sky raider/ridge runner steel tube fuselage jig only it is designed to mount a much larger engine.. Kelly has a Yamaha on the prototype which came out of the jig and to me it looked like the beginning of a super bush plane.. tandem seat, tall gear, designed for bigger engines, still have a swing wing on it like avid and kits and ridge runner, similar anyway...
    If interested, contact Kelly at 360-431-7274.. he is busier than a one armed paper hanger but eventually you can reach him.. 
     
    Leni, sorry if I posted in wrong spot, Im still pretty daft at all this , just recovering from hacked phone and computer and credit cards.. so dont beat me too much...

  8. zadwit added a post in a topic Looking for some advice on a plane purchase   

    I found  the kitfox narrow standard gear makes the plane squirrely and the model 1, 2 have too small tail surfaces... plenty on this site about that..
    Look for a model 4, put grove landing gear on it. Then spend a little time to get the wheels aligned flat and parallel tothe ground, no toe in or toe out, no camber...you can use a laser level to shoot a spot on the tail or again a wall and snap a line down the center line of the plane on teh floor. once you  get the wheel aligned, get a 8" pneumatic tail wheel. You dont need hard tail spring for steering so use softer ones... 
     
    Now start out on grass or gravel adn after a few hours start by doing takeoffs on asphalt or hard surface.. even tually you can land on hard surface, the plane will handle jsut fine, it is just you need to be able to land at a steady speed like 40-45, and with teh plane pointed down the runway.. ie you dont want to land cocked sideways even a little.... These planes are short coupled for sure... but if you do the above and it is a model 4 with the biggier tail and dont put any bigger than 800x6 tires on it to start with, later you can put 26" tires, those are over kill anyway because I flew all over the place and landed off airport with my 800s.
    I have heard of dozens of people who buy a kitfox and ground loop it on first flight... if you look at teh Just super stol, it has a longer fuselage and wider gear both of which make for easier ground handling....

  9. zadwit added a post in a topic Tire comparison 8.00-8.50's   

    YOu could get a 24" long laser level and do this.
     
    1) snap a straight chalk line on the hangar floor from directly below the prop spinner thru the tail wheel and aft.
    2) now park the plane as closely as possible over this line with the line centerd under the plane
    3)Now measure from right tire centerline to that line, do the same for the left tire center line, the idea is to get the plane centered over the line.
    4) now, put the laser level horizontal to the outside of the tire and shoot a beam on the wall behind the  plane. YOu can shoot a beam on the horizontal stablizer leading edge as well. Then look at where the beam hits the horizontal tail on the left and right side... this will give you an instant picture of if the tiers are toed in or out...
    5) If found it best if the tires are parallel and flat to the ground. YOu use have grove gear you can add shims. if not, I have not done this but have heard of people putting a pipe on the axle and bending the gear leg to get it back in alignment.... to each his own i guess.... but if aligned properly, makes for a better handling plane on pavement.

    I have used all kinds of spray equipment for fabric recover jobs and without a doubt the best set up is an airless spray gun. Im talking spraying entire 2 wings at one time or a whole fuslage..  The trick is to get a full wet coat on in a short period of time or else hyou will end up with flat spots.
    For smaller jobs, I have alway used HF 1 qt. spray guns, the old siphon type. THey used to make one that pressured the 1 qt. paint can and so you could spray heavier materil, perfect for
    spraying dope..
    MEK is getting real hard to find however I mainly used it for gun clean up, or for wiping off tops coats of other dopes(randolph) before spraying polytone over it...
    For repairs you can easilhy get by with a small touch up gun..
    Read the stits manual... Ray Stits came up with a good product.. I was recently welding on a fuselage that had Randolph products, rand o proof primer coat, the butyrate dope on top, the randoproof is nitrate base and so the damn thing caught fire and burned all the fabric off the fuselage in less than a minute....stits will not do that so stits is worth the extra price just for that reason... 
    Good luck. Wear a respirator

    The Garmin Area 660 has one wire that provide heading info the Garmin G-5 when the G=5 is in HSI mode. I point to that HSI , the heading bug show the heading to fly to get back to the waypoint, in this case, the airport..

    I made the AOA system with Freds help from France! works great.. I hated to sell the plane but he docs said Id be blind in 6 months.. Turns out they were wrong... 
    After a couple of eye operations and a few weeks recovery, I could see pretty good again... still need reading glasses.
     
    Note: The overlay data is from dashware.. cant remember how I even did  it but it gets its info from the GPS in my go pro which was clipped onto my baseball cap.
    The winds were light that day...
    The Kitfox 4 has many improvments over the model 1, 2 and 3... specifically the wing, the flap system and the larger stablizer and rudder and elevators.
    Kevin Palmer, Trents brother bought the plane and took it to Reno, but it is now back in Spokane someplace..

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

    I had fits with the brakes on my KF 2 and KF4. I finally fixed the KF4 by doing this...
     
    1) Installed Grove landing gear
    2) INstall matco wheels and brakes
    3) Install no bigger than 800x6 tires
    4) installed 2 slave cylinders on each wheel
    5)redrilled the hole where the top of the master cylinder attachs to the rudder pedal top and moved the top of the master cylinder in as close to the pedal as I could...I had to change master cylinder to the skiny narrow one, not the big fat ones with built in reservoir.. THe narrow master cylinders have a hydraulic reservoir on the firewall for fluid.
    6)l I used a  laser and bought shims for the main gear leg to axle interface and shimmed the axles for they were parallel and flat to the ground, no toe in , no camber.
    7) installed an 8" pneumatic tail wheel and using regular springs, made sure there was no slack in the springs, however no tension on them either...
    WIth this setup I could easily land on pavement in 15 20mph cross winds all day long. IT was a pussy cat....
     
    There is one problem. The runner pedals need to be taller for more leverage on the master cylinder, however structure is in the way on model 4 so you are stuck with short toe brake pedals. The most pressure I could get at the brake slave cylinder was 220psi and Matco says you need 400psi.. That is why I added an extra slave cylinder.....I sold the plane but it is still flying in the SPokane area and they guy loves it, easy to fly not bad habits....
     
    I believe the fuselage needs to be 2 feet longer but it was made short originally because of weight plus the original Avid had a nosewheel....
    ANyway if you have a stock setup, it is like jumping on a bronc bareback ,good luck.... sooner or later it will eat you....

  15. zadwit added a post in a topic Bill of sale   

    It was part of the original  FAA rule when allowing companies to build a large part of an aircraft kit for he buyer....IT still needs to meet the 51% rule but the FAA evaluated each company  to determine they did not build more than 51% and  which ones were authorized to sign a bill of sale form to go along with the kit to the buyer.... If a company builds the entire aircraft, they need a production certificate like Cessna or Piper and a Type Design that has been tested. The idea was to have companies build hard to make or fabricate parts for the home builder, yet not go over the 51% rule..
     
    You could 1) contact the local FSDO and ask the question, what do I do now that company is out of business.... OR 2) ask a DAR, maybe they get told how to handle this in training at OKC or 3) worse case scenario, license it as "exhibition airshow".   If you built the ENTIRE plane, you just fill out all the paperwork as listed in AC 20-27 and mail it in and you will get a registration... however there is an affidavit in that paperwork where you swear you built all of it.and  not from a kit........ so it it is a sticky wicket...each company who built the kit would not likely reissue another bill of sale for several reason, liability being just one of them.. I ran into this with a sky raider and since they guy had lost most of the paperwork INCLUDING the aircraft bill of sale form signed by Stace Schrader, I passed on it because it is basically just parts....
