Giant Cessna 185 130"

Hi All-

I've started the big build of my 130" Cessna 185. It's been great to see this giant take shape after more then a year designing it. It will feature a 3 piece wing, removable tail surfaces, and built in supports for floats.

Basic Stats...

Wingspan - 130"
Length - 91"
Power Plant - DA100
Servos - 8 to 9
Weight - Goal weight is 45 to 50 LBS

This is certainly a giant scale project; some balsa trees are endangered! Cessna taildraggers are cool airplanes. One question: how will you develop the main landing gear, what will you use, how will you shape it etc?

Keep us informed with pictures as you go!!

Garyss,

Yes, by far the biggest project that I have ever taken on. I've always wanted a big airplane just never really had the means to do it till now.....This is my first giant scale and first gas powered model so any advise is sure welcome.

I had the landing gear custom made out of 1/4" T6 aluminum. Pics will come shortly.....

Horizontal Stab

Heres a few more pics of the almost complete horizontal stab assembly....

The center spacer supports between the first four ribs shown on this assembly will most likely be removed in my next build as I'm looking for ways to lighten it up as I go.

Great project. Subscribed.

If I may ask:

- These are plans that you developed?

- The parts are laser cut. Are you cutting them yourself?

- Will you fabricate a fiberglass cowling, or any other parts?

- Will you be offering the plans/plan files (for laser cutting)?

Thanks, and I am enjoying your build.

-Yes. These are plans that I developed. I started the design in Oct of '07.

-I had a company cut the parts for me.

-I plan on fabricating fiberglass cowl, tail cone and most likely wing tips.

-Eventually I will offer this as a kit. I haven't thought about just offering the file.

Thanks again

Thanks for the reply. It looks like a solid build.

This is a hobby of constant change.

Recently, I shipped off two sets of large-scale plans to a laser cutting vendor for the estimates of cutting out all curved components of these models. I ended up opting for one of the two. The shipping of the plans was a step that could have been eliminated by CAD (or similar) files. I can see where building of a specific model can be offered as:

- printed plans only
- CAD files only
- printed plans and CAD files
- "short" kits
- "full" kits

With CAD files, the builder does not have to rely on the laser cutter to have the files on hand. At the same time, I can see where the quality of the electronic plans must be able to produce a kit of proper component fit.

With your intent to produce and offer a kit, you are on the leading edge here.

I'll say that this is hobby is one of constant change....When I got back into this hobby a few years ago I had never heard of Lipos and foamies that could actually perform. Back in the days when I was flying glow fuel, electric flyiers never appealed to me now the garage is full of airplane shaped foam.

EJ thanks again for your comments. So far this build is going great and parts are fitting as planned. I think CAD and laser cutting has taken this hobby to a new level. I'll definately offer this as a complete kit, but I wouldn't mind looking into offering it as a short kit or just plans and the cad file. I'm sure I'll have a better idea when I get the prototype complete and have made the changes required for this to be a great plane.

Sure am! It has been a real pleasure to see this take shape. I know this is a unique build and that is what I wanted. I just hope I have as much fun flying it as I am building it.....

Howdy kingair301hc,

Met you in the the hobby store yesterday in SLC! Great to see the thread. The pic on your phone indicated a lot more progress than on the page here! Be sure and let me know when you get close to flying, I have 3-4 friends with 180/185s that would like to see your plane!

Cheers!

SLCPilot (aka Paul)



PS. and their planes are available if you want/need a scale color scheme or just a look at some scale features...

SLCPilot - I'll keep you updated. I have a color scheme in mind but yeah I'd love to see the full size before I start adding the scale features.

Good luck this weekend!
