Thank you Andrew,

The first pair of stabs look great! I have them trimmed up and ready
for the leading edge and trailing edge stock to be glued on.

The second pair of stabs just came out from under the weight and need
trimming and prep but look great also.

I cut and taped together the pieces for both rudders. I glue one rudder
and just placed it under the weight for the night.

I think that is it for tonight.

Slow progress, someone forced me to play golf yesterday and
now the kids are getting sick (back to school is so much fun!).


Rudder/fin, One is sheeted and ready for leading and trailing edge,
the second one is glued and under weight.

Both pairs of stabs/elevators are sheeted.

It doesn't look like that golf game slowed you down much!!

Hey Kelly, what glues (types, i.e. CA, epoxy, poly ...) are you using for the different parts and sheeting, and why? With your construction and building experience, I figure you probably have a great idea of what glue works where, and more importantly, which ones don't. I tend to use CA for the bulk of my construction, and poly and epoxy where needed. I've never sheeted foam wings before, but I hear a lot of guys are have great success using a very thin layer of poly and using water to "kick" it.

Thanks,

-Jorden

Kelly,

I found that template for cutting the hole in the firewall for the ZDZ160.

I've been in bed sick.... will let you know if I'm feeling better tomorrow and, if so, I'll drop it off at your house.

Jorden,

Sheeting to foam:
It was a toss up between Urethane and laminating epoxy for this application.
I decided to go with urethane for ease of use (no mixing) and availability.

Wood frame:
Yellow carpenters glue... No fumes, fun to peel off your fingers, cost,
easy to sand. CA would be fine for this if you like.

Firewall, motor box etc. :
I will use 30 minute+ epoxy... Strong and I can add
milled fiberglass for strenght.

Hope that helps

That is OK Dave, no hurry. I have had a couple of slow
days (ask Kurt) and haven't made much progress.

Here is one of the hatch covers sheeted. I decided to add
the 7/8" balsa strips per plan, but I glued them on first so
the sheeting would cover over the edge and eliminate a
visible joint.

I kept the 7/8" strip one the bottom so I could use carpenters
glue to join it to the fuse instead of urethane. That might
be easier to work with and make a smoother joint.

I will cut away the extra foam later in the build.

Lots of sheeted foam parts.

By the end of tonight I will have all the parts
sheeted except the main wings.

Man, I need to get you out on the golf course a little more to slow you down!! You'll be done by the time I get a chance to come over and learn some tricks of the trade.... Looking great!!

I just wish I could shake this stinking cold....

Any way I can get ahold of the wings from
you tomorrow morning?

Man, I know what you mean about that cold- I spent 2-3 days in bed last week and it's still lingering.

Looks like you got the hang of that foam sheeting. Using Poly Glue?

Kregan,
How many hours are you thinking you will have in each kit by the time you complete them?
I have heard estimates of 600 hours on a Carden and as much as I want to build my own, I can't see taking a year to complete.
People talk like a Dalton builds quicker but I can't see where the great savings in time would be.
The Carden would be worth an extra 100 hours but 400 total seems more realistic.
Any thoughts?

Mark,

I posted something on FG about this same subject. It should only take five to eight hours more to build a carden than a dalton, I don't know who ever came out with the 600 hour estimate. Two hundred hours for a ready to fly carden is more like it.

Mark,
I almost started to keep track of the hours after the first night,
then I came to my senses!

Thats like adding up how much you spend on your hobby... you
don't really want to know!

Sorry to say, this cold is really dragging me down and I have
not made much progress.

Ok,

I am copying Albert on this one.... Here is the layout I am
going with for the main wings.

Ailerons = 51" x 6.5" at the root x 4.5" at the tip.

Laid out with a 1.25" servo arm length.

Kregan,

Its up to you but, a lot of guys set the hardpoints so that when the surface is deflected the pushrod is parrallel to the servo case side.
At neutral, there will be a slight angle to the hardpoint from the pushrod. This way when deflected, your not losing any power to the surface..

Crude drawing..

Thank you for the heads up....

I seem to recall a large thread about this? I think
I was searching for info about "servo resolution"
when I found it.

If I recall correctly some wanted full power with the
surface deflected, while others wanted full holding
power with the surface at neutral to prevent flutter?

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