Thanks for the video, I had not seen that and it makes perfect sense as explained! I currently have a bit of slack in my chains but I will be double checking to see if it's correct.

Great video. That helps tremendously. I guess I need to slacken mine off a bit. His explanation of why it won't go past the detent is exactly what mine is doing. Luckily that's a quick easy fix!
Thanks for posting that up. Wish I had a tailwheel that was even about half that size and pneumatic!

Thanks dholly for the detailed explanation and pictures. That was super helpful. I'm starting to understand the differences now. I've got to run for now, but I'll read through all of this again later today.
dynomike, thanks for the information. gives me something to think about since TW will also be new for me.
IFMT, thanks for the clarification. It seems like the beefed up tubing would be better too since it would resist out of plane bending in all directions rather than just the plane that the plates are installed in. Also, the plates have a fair number of cutouts for controls. The beefed up tubing wouldn't need that. The plates are already welded in though. I'll have to think about that one.
Now, I've got to take off for a while. Thanks again everyone.

Meah, won't be a problem. Other than the girl on the bull machine, I can go over to the Wal Mart to see/hear the rest.

I might accept steel gussets if it's done right. The change up truss from airdale is way beefier than the original. I would have to measure it again. More bracing as well. Cost around 200-250 for the piece. Getting it tig welded in was the big expense.

Not sure if this video has been posted here but when I replaced my tail wheel springs, I followed the directions of this video and my set-up works perfect.

I fly mine with the stock gear off of a paved runway and actually love the way the bungee gear is so forgiving. it just eats up any bounce, and as a new tailwheel pilot like myself is really nice in my opinion.

Luked!
No doubt in my mind the gear you show is stock oem bungee gear supplied with 'most' Mk-IV kits. I say 'most' only because sometimes models overlapped, parts availability to the factory was not always 100% and kit buyers sometimes specified or omitted some kit components. As a result, Avid may have shipped something different than the 'standard' component itemized on the pull sheets. Check the pull sheets you received along with your kit.
If you don't have these, I posted a copy of mine in the Avid Mk-IV Forum that you can refer to for an inventory check of what you have. I also am attaching a pic of my old Mk-IV kit showing the same main bungee gear legs with the integral peg step. The Mk-IV gear legs were heavier and more heavy-duty than the 'standard' bungee gear supplied with earlier B-C models, which did not have a step.
The successor co. to Avid Aircraft, the [old] Airdale Aircraft, developed and sold the W.I.B. (wider-is-better) bungee gear for tail draggers. They also included this as standard main gear for their complete Avid+ tail dragger kits (Fat Avid upgrade kit buyers either used their existing main gear or paid extra for this option). In addition to increased height and width, the tubing i.d. and wall thickness of this gear was also increased and the peg step was changed out to a ledge step. The same W.I.B. gear is pictured on the [new] Airdale Sportplane website and will bolt right up to your Mk-IV. I've attached a pic of the W.I.B. gear supplied with my Avid+ kit.
Enjoy your Avid build, please share your progress pics!

Someone already added gussets into the seat truss. Looks like they are about .040" steel. Is this what you mean, or do you mean to replace the existing seat truss with one made out of heavier tubing?
166, Sorry to hear about your accident. The Grove gear is nice, but I want to avoid the weight, and the cost. Nice looking Kitfox.

allonsye added a post in a topic Possible belly radiator source
I called these folks this morning. The present owner will not build aircraft radiators anymore. However, they will build you a "go-kart" radiator *wink-wink*. Someone there still has the plans for the belly mount and the dual cowl mount.
They don't do aluminum. All are copper and brass. And yes, the made in china aluminum affairs are not reliable I learned.
The materials are expensive. I'm looking at around $700 if I were to purchase some original MkIV spec cowl mount. The belly would be a little less. Tony, the fellow I chatted has built a few of those the last few years.
They're willing to rebuild cores provided they're rebuildable. I'm likely going to send him detailed pics of my old ones I've already posted on the board to see if he will or not.
You can email them at unitedradiator@hotmail.com. Be sure to put "go-kart" radiators in the subject line. Call or email, just make sure your talking go-karts not Avids or Kitfoxes --.
The other option I found is http://www.griffinrad.com/. Hit the red bar at the bottom of the page. There's a custom build page you can submit for a quote.

I contacted a local radiator shop yesterday to see if they could fab one up hope to hear back today about pricing.

High Country added a post in a topic Enclosed trailer for Mark IV Speedwing
Russ,
if you get a chance could measure what the spacing is on the wall studs (24"?) and in the roof, and also what size tubing was used in your trailer. I started building mine last fall its currently just a flat frame waiting for walls. I hope to be needing it in by early summer. yours looks exactly what I had in mind. I'm thinking of making the walls with Styrofoam glued between the studs and into the roof with some vents. also want to put a small man door in the front and a wall separating a small room up front that I can keep tools, parts, etc in. what do you guys think anything else I'm forgetting?

EDMO added a post in a topic Hello and to the point
Leni,
I thought the rule was that the builder who applies for the paperwork HAD to list himself as the "manufacturer"?
What other "manufacturer" could there be? Certainly not the Kit company?
Or did you mean that this guy put his name as the Make/Model in addition to being the "manufacturer"?
Have I missed something about NOT listing yourself as the manufacturer?

I'm a fan of the grove gear only because it puts the wheels wider and about 4" forward of the origninal. Between the grove gear and fixing the brake pedal geometry, I can land on pavement with confidence.... However, too many agressive landings may have stressed the clamping bolts/nuts. When doing the post mortem, it appeared the nuts stripped off the right clamp leaving the clamp nowhere to be found and a wild ride on touchdown. When I get back in the air, it will be with 3/8 bolts instead of 5/16 with two nuts instead of one.

Always due the seat truss upgrade if you change the gear. Wide gear exerts a greater moment arm and thus your seat will get way lower with a little harder than greased landing. Just get the heavy tubing change up. Plywood glued in isn't worth the effort. Do it before the fabric.

I like the heavy duty wide gear for more than one reason. My plane was wrecked twice before I bought it due to the gear folding up on the stock gear. plus the narow gear is just not as forgiving.

Luked added a post in a topic Looking for info on landing gear options
Thanks for the welcome. I actually posted an intro a little while ago I also started a build thread, but it's kind at a stand still right now. I sent my crankshaft to Aircraft Specialties, and I'm just waiting to hear back from them if it's any good. This project will probably be a fairly slow pace because of time and money (hopefully not too slow though). You can find my project in Avid Mk IV under "Lukes MKIV Project".

Thanks for the link. I hadn't seen that picture before. The picture of the stock gear looks a lot like mine. The angle looks pretty similar.

The builders could have screwed you there.. Mine is registered as a "Elrod Dennis B" avid flyer.. But it's an avid C HH.. A lot of the builders registered themselves as the manufacture.

That looks like standard Avid gear. I put the wide gear on and it helps. Bigger help in keeping it straight is lock your tailwheel pin! Check airdales old site,http://www.airdale.com/widegear.htm

Hmmm... that's definitely not what I've got. Bummer! Are you saying this is actually the basic stock Avid gear?

Yeah, I agree, and will get some training when the time comes. I just kinda wanted to figure out what I have, and how it compares to other options.
