Hey DAG,
Ok, you realize how interested we are in every tiny detail, right? LOL In a photo on post 1564, I see you're using Epoxy and hardener from PTM&W Industries. I'm not familiar with that product myself. What is the working time? Is this what you use for all your epoxy applications? Will it also be used as finishing resin when you glass the airplane?

Sorry. I feel like I'm slowing you down by asking such questions.

Hi DAG,

Been lurking for months and admiring your ingenuity. My friends, Mike and Rich, are the guys with the scratch built B-36 on the Highflight cover this month. I helped them a bit with their electric power system evaluation and computer analysis since electric multi's were new to them. As Mike mentioned in the article, the AUW came in at about 25 lbs, and we measured ~210 ounces of static thrust from the system at WOT. It flies it in a scale manner, with not much more to give. From the sounds of your setup, you'll cruise at part throttle easily.

Your CF tubes remind me of the two I used for the plug in wings on the Spruce Goose (in my case 5/8" D x 30" long- mere drinking straws for this beast!). They'll serve you well- amazing strength in a lightweight package.

This is really going to be a cool project.

Tom,
The epoxy I use is aeropoxy from aircraft spruce it is made by PTM. It is made for joining none like materials like aluminum and CF. It has a working time of 30 minutes and is 100% in about 24 hours. It is thicker than caulking so it would not work for finishing. It is great stuff.

Hi Mike,
That B-36 is cool. Seems almost all scratch built aircraft come in just a bit heavier than we want. I saw a thread or a website on it somewhere and it looked to fly well.

Thanks, DAG

Yep, That was 18 bottles of Zap glue ago, and 5 band saw blades ago, and about 10k ago .

But oh what a great day it has been,I got all the wing jack screws installed to level the whole wing so I can align the main CF tube spars. The wing is within 1/32 of being true and straight.

I will post the photos later tonight. Kind of a bitter sweet week ahead, I have so much work to do for my business that I will get zero done on the 36, but the great part is my business is still busy with this crappy economy so I can pay for this bird.

Thanks all,
DAG

Dag if you get this magnificent model complete in time consider taking a vacation to San Diego for the Silent Electric Flyers of San Diego's Mid Winters Electric in May. (http://sefsd.org/mwe.htm) or one of the airshows from the Palomar RC Flyers club. I'd love to see this thing in person.

There are tons of RC clubs in OC an SD county and the weather is usually nice. There's a nice Air plane museum in Balboa Park and Chino has a great museum.

Great progress Dag! It's good to see a well thought out project coming together so nicely. Maybe we can convince you to subcontract your skills out to the ARF manufacturers..... On second thoughts let's just clone you instead so the build keeps progressing.

I don't know how you find the time to balance work, family and this......oh! that's right, who needs sleep?

Here is what I got done today.

The turn buckles are used as jack screws to level the wing sections. The thread on top is so the when all come into alignment the entire wing is then level on one plain.

I am very happy with how this has all worked, and after checking 18 points the wing is trimmed level to 1/32".

When I get back to it the end of the week I will then epoxy all wing tubes in, then I will be ready to start sheeting the wing .

Very nice, I like that quite a bit.

Where did you get them?

I've gotta keep that in mind if I ever build something close to this big.

Your right, but they were purchased for a vintage project that is 90% complete that had flying wires. I have 32 of the turnbuckles.
