257" B-36D Build
Well,
This is the start of my thread on my B-36D project I also have this on another forum as well. I started the design 8 years ago with the intent of it be 256" with 6 gas engines, but after doing all the calcs I realized that the plane would weigh over 110 pounds because I would need 45 pounds of ballast to off-set the engines weight at the trialing edge of the wing. Now with electric motors I can build a 257" B-36D and hit about 51 pounds. I have drawn the entire plane in both 3D max, and AutoCAD so I can scale the drawings to any size I need. The plane will have 6 AXI 4130/20 Motors turning Zinger 3 blade 20" props, or 6 Neu geared motors, in testing I get about 5 minutes at full power and 12 at 65% cruise power. I have just got all of my plans printed out on my plotter to start cutting wood. The retracts are going to be Century Jet Models, Inc. and be Scale b-36 gears. I have been using Ecalc and it looks to be spot on with what I am seeing in testing.
Will try to update weekly or better.
Attached is some pics, one shows my girl holding the #2 rib, and the other shows my son holding the #2 nacelle.
I have posted here because a bunch of my pals said that I should.
Thanks, DAG

I seen one at Bomber Field Tx. for the B-17 gathering in 07'
it was near finished , 20 to 22 foot wing span, & six G 38's or G-45's
Don't know who it was for , but , it sure was NICE !

Dag,
Have you estimated build time/ what is your finish time goal.

at least we have a definition for giant scale. there's a thread out there somewhere where guys with 70" ws planes are insisting that their's are giant scale.

Awesome project [X(] I will be watching this one with great interest. I hope one day not too far away to start on my own dream of similar ws Short Sunderland, but that will have to wait till I move to a house with room to built it [&:] I currently have 2 DC3's, one on floats on the go and I am struggling for room working on just one [:@] even my living room looks like an airport disaster area [:-] Glad I'mn single, or I'd never hear the end of it
What size batteries will you be running with those motors?

That's quite an undertaking. I hope you can stick with it to completion. So many of these really big projects become so overwhelming that the builder loses the necessary drive to finish them.

This link should take you to a B-36 site that shows the airplane to which he was referring.
http://www.b-36peacemakermuseum.org/...fundraiser.htm
It belongs to Jim Anderson from the Dallas,Tx area, and has been under construction for several years. The fuselage is now complete and painted, but the wing is still under construction.

To my mind anything "Giant" usually means 100" and above. I laugh at fools who call thier smaller planes Giant or gas only to find they are std 40/46 glow planes. There is one fool on Ebay who calls his planes "Giant" and the biggest he has is 40"ws. I couldnt help myself and sent him a message saying I was going to get on to ebay and get them to take action against him for misrepresentation of his items, but he kept listing his toys as giant and I did get onto ebay, explained what a Giant really is, I got a message back saying they will take action.
One of the biggest hasles I find building these big babies is not the work ot time involved but space, especially as it comes together. Its happened more than once you finish a section and put it aside, only to trip over it or ding it some other way. we were nearing completion on my mates 144" cub a while back, and had put the wing aside finished bar for the installing of servo's and links when we had another rc'er visit. he stepped backwards and into a wing and fell on top of it totally destroying it. I had to take my mate outside and give him a beer, and he dam near crying, we had built this from scratch, cut everything ourselves, and now we had to do anothr wing [&:] it was 3 weeks before he wanted to even look at it again [&o] sadly the clown that did the damage didnt even offer to help, let alone pay for materials etc, needless to say he isnt welcome anymore.
One thing I have found building big planes is not to have the attitude I have got to work on it every day, I build when I feel like, that way I enjoy it and seem to accomplish a lot more with fewer mistakes/mishaps. Pushing yourself is just asking for problems because half your mind is saying "I dont want to be here" instead of being focused on the job at hand [sm=confused.gif]

RE: 257" B-36D Build
It is funny, my 50% Pitts s-1 had a 110" wing span and took about 6 months longer than I had wanted, but it flew. My 193" vintage is done but took a year longer than I wanted, it has not flown yet because it has some shaking in the tail when at idle, but that will go away when I go back to my old engine mount. Giant scale for me has always been over 100" I see guys talking about there giant planes and I am sure to them they are big, but 70" even if 1/4 scale is not that big.
Attached is my 1919 before I stitch on the fabric like in the old days, yes I stitch it on, I have over 500 feet of cord and went thru 2 needles doing it.
The 36 will fly, except for my 29 wing being made to weak, I have never started a project that did not fly.
Thanks all,
DAG

Article IV - Acceptable Aircraft
Section 1
The purpose and goal of the International Miniature Aircraft Association, Inc. is to encourage and foster the building and flying of large radio controlled model aircraft. The term "Giant Scale" is also used by the Association to describe such aircraft. However, this term and the term "Large Scale Radio Controlled Model Aircraft," are in reference to the size of the model and not the full sized aircraft. The concept of "large" radio controlled model aircraft shall prevail over any other considerations in describing miniature aircraft. This concept of "large" is generally considered to apply to radio controlled model aircraft with minimum wingspans of eighty (80) inches for monoplanes and sixty (60) inches for multi-wing aircraft. Ducted Fan and Turbine aircraft with one hundred forty (140) inches combined length and width, measured from wing tip to wing tip at the widest point perpendicular to the fuselage and added to the length of the fuselage, excluding any protrusions. Autogyros with 50 inches for a single rotor, 80 inches for a dual rotor. Quarter (1/4) scale replicas or larger with proper documentation (minimum 3 view drawing of an actual person carrying aircraft) which do not fit the size requirements will be permitted. However, the concept does not encompass radio controlled model aircraft so large as to have the potential of carrying a human being. Turbine aircraft will have the same combined length and width requirements as Ducted Fan Aircraft. In addition, each participant that will operate any model aircraft powered by a turbine engine will sign the AMA's 'Statement of compliance concerning Turbine Engine Operation' and the aircraft must comply with the AMA's 'Safety Regulations for Model Aircraft Gas Turbines'.

As for the actual topic and the B-36 project, AWESOME! That is going to be pretty spectacular to see completed.

RE: 257" B-36D Build
when I contacted ebay, they said they would find out what constitutes "giant" scale and then take appropriate action. I suggested they contact AMAA which they said they would after I told them who they were. Its not for me to tell them whats what unsupported, thats why they have a legal team, let them earn thier keep

RE: 257" B-36D Build
The B-36 is Golith (sp) scale! By bigest on the board currently is a 1:6 scale Howard 500 at 142", next smallest is a 132.625" 1:8 scale Dornier Do-24T. I like the big boys it is so easy to make things happen with the room they have in them. It is easier to cheate hardware and fittings that are true scale. Love your work!

I'm considering switching to something like Drupal again but I change it so little I waffle on whether I should bother or not. I have templates for the HTML where I simply fill in the blanks so it wouldn't save me much time I don't think.

I saw a 70% Staudacher at the DOGS show in Datyon a couple years back, to date that is the largest RC plane I have ever personally seen. I've seen larger ones in photos but that's the biggest one I've seen up close and personal.

Nope, I am here, been traveling for my company.
The 36 is moving along well for all of the traveling I have been doing. I will post pics of the fuse truss in the next couple of days.
Thanks, DAG
My website for my planes:

I will be also posting my higher res pics there.
