Bluecore F-14, work in Progress,,,,,,,,,,,

Okies, started building an F-14 Tomcat Foamie today. Going to go with 2 Hacker B20-31s Brushless motors, 2 CC Px 25 Esc's, 2 3s LiPo 1200 Batts, Futaba PCM 149 Dual receiver, 2 HS-55 servos, 1 Dragonfly 9grm servo ( for retractible wings). Unsure about AUW right now.
Going to try to go with retractible wings on it. It's 33" long, wing span 34 1/2" open and 21 3/4 closed.
It's going to take a bit so, sit back and watch me make an idiot of myself.
It's my 4th foam build.
1st was a Bipe, it flew
2nd was my Flanker, flies great!
3rd SR-71, lumbering idiot, not enough power, too heavy, she sleeps with the fishes now.
1st pic is what i started with.then it's just a progression of what came next. Trial and error to make new panels.
The last is what i have come up with for the main body.

Double WoW !!

I look at this and drool. My biggest question is how the swing wings will be actuated. It's probably simpler than I imagine but I still need to know. Of course I am sure you will let us know in due time but I can hardly wait. also will you include flap function to go along with it?
Good luck and I will be following along. Looks great so far

I'm going to go with a Push Pull system. At least, this is what i'm going to try.
Using a servo to push and pull the center rod will cause the wings to pivot in and out.
2 CF rods inside a Brass tube with ball links. I'm putting 1/8 bass wood in the root to stiffen it up. I'm going to use a bearing in the root for the pivot point.

Cool

Can't wait to see how this turns out. I am interested in doing something similar with a B1 Bomber. The wing mechanism is the tough part. Have you thought about a single engine in the pusher config instead of twins? It would be easier to do. I don't think it would take away from the appearence. Just a thought.

FW,

This is very cool, and don't worry about mistakes, your breaking some new ground here so keep going.

If I could, let me suggest you consider adding a basswood plate above/below the pivot point. This would help spread the loading across the upper fuselage section. I might also consider a thin plastic washer say 2'' in diameter to reduce the pivot area friction.

Bob.

Yuppers, already going to do it. I'm going to put a basswood strip covered with CF on top and bottom to make it more rigid and keep it from moving the pivot point.

Comming together. Still in the trying to figure things out stage. Cut in the tail feathers this time.
I thought about single motor but, i would need allot of power so, i went with 2. I'm still looking for that faster than life build.

Well, one side of the wing system is done. This is what i used and what it will look like. The other side will be the same. Then i have to make a track system for the middle pushrod to keep it from canting. I I used a 3/32 x 3 x 3 piece of Basswood for the bottom securing. The same basswood for the upper and lower wing inserts above the bearing. The bearing is inside the wing. The top got a piece of a CF sheet. It pretty much free floats.

You've probably consumed a mere 2 dollars worth of fanfold so far. Isn't this stuff great for this kind of design work?

Looking good! And looking forward more more!

Thanks Thomas, yuppers, about that. Love this stuff! And, i'm a huge fan of CF.
I'm diggin the 27 i have, made from your posts. Flies great.
I'll keep everyone posted as progress continues. If it flies, then i'll try to post plans for people who want to do it.
