I'm glad to hear that Zenair has decided to start tending to the ch-640 again.
For a while there it seemed the 640 had become the unwanted step child of the
Zenith line. Did you notice if the wing spar error that Chris Tremblay had found
is now updated in the drawings?
I had tried in an earlier post to coax folks to help keep track of updates on this
list so everyone all had the latest information, as Zenair does not care to
inform the 640 crowd of any changes. The only thing that's changed on the website
since 2005 is the price of the kit.
Hopefully they include an updated set of drawings with my fuselage kit.

At least at the time I finished my plane, the FWF of the 640 was the same as the
801 except for the engine mount. So theoretically, FWF packages for the 801
could easily be adapted to the 601 as far as getting it to fit. W+B issues, thrust
line issues, and engine mount attachment points would seem to me to be the
main things to check out prior to going that route.

I actually wrote Tim Ward yesterday asking this question.
This was the reply:
"Tim is no longer with Zenair. I will be handling all technical questions and any
sales support is handled by Anita Mitchell."
Anybody know what happened to Tim?
and they also said...
"The firewall is the same on a CH801 & a CH640. I have spoken with Travis @ Kobush
Welding and he has built engine mounts for the Franklin engine on the CH640
& would be glad to build one for you."
So this verifies the fact that the 801 and the 640 have the same FWF.
I suppose the thrust line (as mentioned) would also have to be considered.

If you dig around on the Zenith 801 builder resources section I think you can actually
find the thrust line drawing for the 801 still. I could be wrong.

Craig,
Those are all PowerPoint autoshapes.
Would you like me to create something for you?

Never knew power point had the capability, but I looked down at the bottom status
bar and there it is. What did you use as a basic drawing, or did you make the
whole thing from scratch?

The entire thing was made from scratch.
It started off as just a multi-sided polygon. Then just keep adding points and
curves until you get the outline of an airplane.

All they did was transfer the hand-drawn plans to computer-drawn. The wing spar
error is still in the plans.
They also added a few typographical errors in the transfer. Luckily in a couple
of places, I could compare a picture of the hand-drawn plans (e.g. P1010080.65.jpg
in the Stage 2 fuselage directory) with my computer-drawn version and resolve
the differences. But most of the time I had to calculate the correct numbers.
I still plan on posting the corrections I have found so far, but I wanted
to collect them into one document first. I'll start a new thread when I
get this together.
I wish we had a centralized web site (something like http://www.ch601.org/builder%20resources.htm) where we could post our collective knowledge about the CH640. Searching through this email list is not optimal for future builders.

That's great ! I didn't know about the Wiki feature.
I have started the CH640 wiki at http://www.matronics.com/wiki/index.php/CH_640. I will fill in the errata page with the items I have collected so far.
