This seems to gives a good balance from neutral to endpoints.

Anyway, I will sleep on it.... Maybe Kurt and I need to
conduct a 18 hole meeting and talk this out!

Status: offline 		I finally had time to do some wing prep.

First I made a template for the servo layout. I like working with
templates to reduce the chance of error.

I needed to cut the servo wire holes so I broke out my Weller
soldering gun and made cutter out of 14 ga. copper wire. I had
seen pictures of this done and just copied it.

Laid out the servo wire channel (straight line) checked the plan
to make sure servo wire would exit in a good spot and burned
the holes. I used an aluminum angle as a straight edge and
a depth guide.

Next I routed out the servo locations, glued in the servo mounts
and put everything up to dry.

Keep up the good work! Looks really nice so far. Does Carden put the holes in the foam for the wing tube or do you have to do that?

The Carden wings do come with the wing tube
hole already cut.

With the wing tube sockets glue in place that completes
the wing prep and I am ready to sheet the first main wing.

I put together the sheeting for one wing tonight.

The wings are approx. 53" long. The wing sheeting is
48" long. The instructions have you glue all the extra 5"
sheeting in a straight line out near the wing tips. I decided
to deviate from the plan and cut 1.5" off every other strip
of sheeting to create a staggered joint. This would hide
any straight glue line that could possibly show up under
the covering.

Wayne and Steve...
I will take your advise and offset the hard points a little.
They will be added later and I can adjust them at that time.

I hear from Dennis that Wayne's plane, built by Walt was at the
Toledo show... I told Dennis that my goal was to try and achieve
that level of quality! I hope I can come close! Kurt is even getting
a balsa servo wire tube (maybe) !

I glued up the sheeting and got the first wing under
weight.

I come up with 460 pounds with the tile and brick.

Status: offline 		Sorry I could not make it out to fly today. Rachel had a great
idea to take the kids to Centenial Park for a "trick or treat trail",
to bad 15,000 other moms, with 2.5 kids each, had the same
idea!

Back to progress.....

I have one wing sheeted and trimmed ready for LE and TE.
The other wing is under weight. I also pulled out the next
pair of wings for a picture in the buff.

Look at the wasted foam in the box, any ideas for that besides
dumpster fill?

BTW,
Any problem using urathane glue for the LE and TE instead of
aliphatic resin (wood glue) that the instructions call for? My
though is the urethane would force itself into the edge of the
foam and balsa filling any small voids.

It will work, use a lot of tape to pull it down, every 2 inches or so. I use Titebond II. Its less mess and works just as well maybe better in my opinion. Tips and end caps I use 5 minute epoxy. I use an acid brush with the bristles cut back to 1/4 inch. The epoxy can be brushed real thin just enough to stick it on. In a couple minutes you can shape the piece and the epoxy will sand clean. Done correctly its very light, very little glue, Walt
