I can't really speak to factory support at this time since I finished my plane
3 years ago. It does seem that the 640 has been given little attention by Zenair.
Do make sure you have the rear seat plans that were updated. The seat is now
4 inches back from where it is in the prototype. This change was made about
4 years ago, and was included in my plans (#0052). It doesn't interfere with
the flap motor, but you do have to design your own way of attaching the steps,
as the bracket sent with the kit does not work as shown in the drawings. I attached
a few photos of how I did it without changing the brackets. While not elegant,
this method has held up fine over 600 hours.
Just a hint; use about 1 1/2 inch of high quality foam on the rear seats to maximize
space and 1 normal sized adult is pretty comfortable in back.

Hi guys,
Has anyone else noticed that with the inclusion of the 650 and 750 on the zenith
website, that the CH 640 has disappeared? I wonder if they will keep selling
plans to it?

It's still listed in the text below the pictures. The Zenair 640 site is still
up.
I specificly asked the question of Zenith after the announcement of the patriot
from AMD and that ALARUS production would be special order only. The response
was that the 640 was going to continue to be offered. I too was concerned about
kit production. Hopefully things haven't changed in just a few months.

My SN is 0078, with the baggage shelf in the plans, so I'm guessing that the seat
mod is in there too.
Thanks for the tips. Is there a dimension in a drawing to double check for the
seat mod that you can think of, it would be greatly appreciated.

I'll have a look at my drawings tonight and check the revision date and some measurements.

Hi all, I am new to the 640 community. I just ordered my plans while I was in Iraq
(s/n: 094). I did a lot of research while there and found many similarities
between the 640 and their other models. Tim Ward was extremely helpful. I am
home now and will be ordering the tail kit here in the next couple days. Thanks
to all for the great input on this forum. It's all been very helpful and educational,
even the not so good stuff. I'm glad we have this site to share ideas
on finally. My wife and I were planning on visiting the factory in Canada to
pick up the tail kit and see the demo model. Tim informed me that the demo model
was at their plant in Georgia, not Canada, but they'd be happy to give us
a ride and tour down there. He also stated that I could pick up kits from their
plant there. Possibly saving shipping for me. So far I have also noticed that
the internet information for the 640 is severely lacking compared to their
other aircraft. They have been very good at communicating with me via e-mail thus
far though. Tim Had my plans to me in Iraq within about 10 days after receipt
of my payment!! I hope things keep going as smoothly as they have so far.
Here is my kitlog website if anyone is interested.

I have all my tools and am ready to begin the build as soon as I can get the tail
kit here. Hope to keep in touch with all of you.

Mark,
Welcome to the 640 community. It's good to see quite a bit of activity
surrounding the 640. I guess getting our own list has helped.
I would highly recommend at least one visit to the factory. I went
there twice, once to pick up my wing kit and another to get the canopy
kit. Tim provided me with a plant tour and showed me various
subassemblies that they were working on at the time.
You're right there are many similarities. About 90% of the 640 is from
the certified Alarus. My dad is building a 601 and you definitely
notice common techniques and assemblies in it also.

| Subject: | Riveting the stab |
I shot 8 AD5 rivets on one of the hinges today. Since I have no basement or garage,
I'm building in my hangar.
Anyway if you drill the hinges and brackets to the drawing, you will have difficulty
setting the rivets over the doublers. New builders take note, subtract a
couple mm from the outboard locations. I had to cut away the nose piece of one
of my riveters to shoot the A5s, and sand off some from the side of the solid
rivet set to get in next to the doublers. Also had to drill out one particular
rivet 3 times before I got it to set properly.
Being a novice rivet setter, I decided to let it go for tomorrow to finish the
other hinge bracket.
Tip, wrap your bucking bar in leather if it has a rough cast finish or it will
make you some rework on your brackets surface finish.
To learn solid riveting, I made up some simu-spars from scrap aluminum. I built
a total of 6, with the last 2 matching the spar stack ups, to check how the rivet
lengths worked out. Oh, foo'd up the original brackest so had to make my
own in 1/8 angles.
