If all goes as planned it looks now that I may have the 36 flying by late March, so far it is going much faster than I thought it would. Money might be what slows me down.

I have seen some plans for a B-52 at: http://myunclewillies.com/about4.html2.html
Look at the bottom. I have really wanted to make a 200" B-52, but I have not 100% gotten the electric prop thing figured out yet. To design a 8 engine EDF would be a huge project to tackel, if the 36 comes in 6 pounds under weight I thought of putting 4 EDF on her, that way I would have 6 a turnning and 4 a screaming .

Unclewillies plans are hot and cold, some planes are great, and some are really old and you have to re-design 85% of it to work.

thanks for the plans site.

The edf's on the 36 sounds a really good idea

what ever you do you must out lots of videos of the 36 all over the web

Well I am back to work on the 36. Attached are links to my gear test animations.

I will be using 2 HS-7955Tg, thats 666 Oz, This way I won't be getting the plopping down like you get with air, also being digital I can set the speed for a retract of 25 seconds.

After the video plays you can click it again to go to the youtube then play it in high quality.

25 seconds is a long time for gear deployment but this is awesome.

Have you thought about making the joint closest to the landing gear rotate slightly past 180 degrees and putting a stop by it to keep it from over rotating. That would drive forces from a crosswind/sideslip landing into the stop instead of possibly back into the servos. You would probably only need to go a few degrees past 180. With no stop that joint has to be kept and a nearly perfect 180 degrees to drive forces into the bellcrank pivot.

It may be hard to see but that is just what is happening. With the gear down the actuating arm has a flat spot that locks when pushed into postion, when the gear is up the push rod arm is at zero degrees axis to the servo pivot point, that is the locking in the up postion. The travel is 185 degrees. It is hard to see, but there is zero load on the servos once it is either 110% up or 110% down. 25 secounds is scale to the real B-36.

Thanks, DAG

I figured you had that covered, just wanted to see how you accounted for it.

Thanks for your info, I may still miss things that someone can help me with. I welcome all comments. I had designed this method for my B-29 but could not keep the weight down enough so the servos would not be working to hard. With the a CF tube for the strut I think I will be fine. If this does not work the gear mount foot print is that of the Centry gear design.

Thanks, DAG

Dag !!

That is so cool !!!!

Dag, I dont know anything about these animation video test's or any of your computer skill's to tell the truth...

Does the retract video work just as the real stuff that you will have to fabricate ?

What I mean is, If you copy in size and all just what you have drawn in the animation will it work exactly the same or will you have to perfect on it a bit more ?

I have another stupid question, I hope you dont mind...
Do they just use the jet engines for take off and then turn them off once in flight ?

Also I wonder why they didnt design the jet engines a little closer to the fuselage ?
It just seems as if they could have pushed better there rather than so close to the wingtips...

I barely know how to turn my computer on to check out the wonderfull things you can do with yours !!!

Yep, it all works as drawn, I can actually tell it what load the spring are or what load the dampers (shocks) may see.

The engines were used for take off and landing and when on the bomb run (for added speed to get away from the nuke so it would not hurt the plane).

The engines were out there so that they could utilze the strong points of the wing, also because of where they located the fuel system to feed the engines. Most people dont know that these engines were set very cool (rich) and burned actual aviation fuel not jet fuel. The small tabs on the exit pipe of the engine was to tune it to burn cool. This way the plane was a single fuel type plane.

Man have I read to much about this plane.

Thanks, DAG

Very cool Dag !!!

I am very impressed with your animation drawings and the tests you can do with them !!!

Thanks for answering my questions !!
That is interesting !!
And yes...I didnt know they ran on the same fuel as the other engines eather !!!!...lol lol lol...
But I guess that doesnt suprise anyone !!...lol lol lol...
