I bet closing up a wing would go pretty fast with one of these:

Thanks for the replies--I presume that there's no trouble with heavy snow loads (permanently) deforming the .016 skin between ribs then.

As I was leaving work today, I noticed several Cessna 150s and 172s were still sitting on their tails from the snow load on their horizontal stabs from a storm last week. It got me wondering how the ...

I don't think it was mentioned here, but there's a rivet puller page on the zenair builder site that addresses having to make 2 pulls to drive the rivet. See page 2 at: http://www.zenithair.com/pdf-d ...

Bob Kissell, the originator of this thread, accidentally sent this to just me instead of the whole list, so I'll cut-and-post it here for everyone to read. Kudos to Bob for taking the experiment to t ...

Great study of the issue, Bob!

I was curious about this problem and its solution in production aircraft. A web search revealed the same complaint from everything from Yaks to Cessnas. Of course, ...

List, Please forgive me for going off-topic here, but Dan, what is the substance brushed on the aluminum in your 2nd (interior) photo of the antenna?

I just noticed that in addition to adding the 750 plans to the Zenair site, they have also revised their prices (upwardly) on the other stuff. I'm not sure about individual components, but the 701 pl ...

I didn't see the previous discussion, but as a current tower air traffic controller, I want to hear "...Experimental Zenair [callsign]..." on initial contact. If I need further clarificati ...

Rick,
1 x 1 x 1/8th extruded structural aluminum angle, 6061-t6, with a proper
radius is available from Aircraft Spruce as p/n 03-48000.

Careful, the plans (for the 701, at least) call for 3/4 ...

Looking at Gary's description, I think he used a nylon WASHER on the hinge pin between the hinge plate and the elevator. I don't believe it was a nylon BUSHING around the hinge pin itself and between ...

Thanks!

...Here are the profiles of the angles to which I refer:

also rounded down, so it may be possible that the overall cross section is less than the squared angle.

I don't think it'll matter a whole lot--the .125 thickness is already more than the plans cal ...

I am still preparing to pull my first rivet on a plans-built 701. I have found a reasonably-priced local source for the aluminum sheet and extrusions (Yarde Metals). They have a good selection of 60 ...

This would explain why I ran out of gas, for the first time in 13 years, in my pickup truck a few months ago. The gauge works and was reading a little less than 1/4 tank.

You have a capacitance fue ...

As I prepare to embark on a plans-built 701, I can't help but think that I'll spend a considerable amount of time laying out and building non-flying items such as forming blocks and flanging dies.

Hello Everyone,

I've just received my set of drawings for a plans-built 701, and I have my first few (of many) questions already...

I'm trying to plan ahead and see that the wing spar caps are . ...
