Lockheed L-1049 Super Constellation Plans and Modeling

[Grifflyer]

Cool, what software do you use for the 3d modeling?

 

[unrauv]

Built and tested the left vertical stabilizer. The servo wire will be pushed into the slot beside the servo. Does any one want a video of me building the right one?

I'd like to see a video of how it's built, are you planning on putting a rudder on all three vertical stabilizers?

 

[unrauv]

Yes I have designed all three to have active surfaces. I will have to cut a temporary horizontal hòlder for rudder.

I will have to use a go pro hero 3, do you think that will be okay?

 

[unrauv]

I did a video of building the vertical stabilizer.. Hope its not too boring!

 

[unrauv]

I did a video of building the center vertical stabilizer.

I enjoyed it but as I get older, my attention span and patience are waning and I found myself skipping through to see the next operation. Perhaps a mix of the regular speed shots to show the essence of what you are doing combined with time lapse (or just speed it up in a video editor) would help pace the video?

Love what you are doing with the edge sanding - do you find that it really works to prevent the paper lifting?

One last thing - we gotta get this man a bench! (my knees were sore in sympathy watching you work ).

Yes I have to go through and double the speed in areas. I know you think my knees are bad, I live in a very small space.
I have compressed the whole videos by 4X in YouTube, give it some time to finish.

Added some engine details...

 

[unrauv]

Tail construction test fit...

 

[Ketchup]

This plane looks great! Good luck!

 

[unrauv]

Thanks man!

Currently cutting all the fuse bulkheads, will be visiting the print shop for fuse and wing 54" x 35" prints. You just can do this with tiles and keep them straight.

Build pictures, man this is a big model! I will unfold it and show the interior bracing.
Build helpers will be shown on the outside of the fuse.

 

[Grifflyer]

That's HUGE!

 

[unrauv]

Yes its large model. You don't really get a feeling for scale until you build it. Tomorrow I will cut the wing plate and take some more pictures of the inner frame. Still trying to decide the power.

Option 1 : 4 x 28x26 1200 kv running 4S using 8 x 6 propellers.
Option 2 : 4 x 28x30 1200 kv running 3S using 8 x 6 propellers.

4 x 28x26 1200 kv
Published output : 286W @ 15v (4S) x 4 = 1144 watts
Published output : 215W @ 12v (3S) x 4 = 860 watts

Any advice??

 

[Namactual]

That looks great Vincent!

 

[unrauv]

Thanks Namactual!

Some internal pictures of frame braces in wing plate...

 

[unrauv]

Weight of fuse after gluing and plywood = 0.475 kg = 1.045 lbs.
Next up the wings...

These are the HK NTM Propdrive motors? The 2826 1200kv on 4S and 8 x 6 might be pushing the motor to the hot side. Do you have room for 9 inch props?- the NTM2826 can easily spin a 9 x 6 APC (and 10x6 APC) type prop on 3S. If these are the propdrive motors I can run some static thrust and current draw tests on the 2826 size (I don't have a 2830 to hand). Let me know - I have 8x4 APC type, 8x6 APC type, 9x4.5 (SF), and 9x6 APC types I can test at 3S and 4S. Would be good for me to let my inner (?) nerd out for a couple of hours.

I have room for a 9x6 prop. I will test the trust on my B-24 that I have never flown. I will do a motor test today with 8x6 props and then 9x6 props.

Propdrive 2826 1100 Kv with 8x6 props.
Propdrive 2826 1100 Kv with 9x6 props.

I just weight the wing of the B-24 with all the gear installed, 1.75 kg = 3.8lbs.
Fues weight of B-24 all gear installed is 0.870 kg = 1.90 lbs
2 x 2200 25C 3S batteries = 196g x 2 = 0.392 Kg = 0.86 lbs

Total flying weight = 6.56 lbs

Wing Area Left = 143247 sq mm = 222 sq in x 2 = 444 sq in.
Weight per Sq in = 6.56 lbs / 444 sq in. = 0.0147 lbs / sqin

The Connie will be of similar magnitude with a little more weight for the Fuse as it has the triple tail and longer fuse.
