The question is how to build this light enough, where the 1.25" props and 0408 motors manage to give the right thrust

 

[FoamyDM]

I think I'm going to play with paperless construction I think...
When I scale this down, so the props are 1.25" the wingspan is around 46" - That's a Blunt nose Versa wing. (which it kinda is.) just way more drag area.

This is totally insane 😱 ... but I like it 👍

 

[FoamyDM]

I might have to buck up and go with 0820s or1020s. with a 2.5" props...
This was originally gonna be a paper plate model, about 1.5mm foam, but I'm not sure what's the best approach with such a wide wingspan with such little thrust...
I'll likely play with it some tonight. maybe get the upper Motor Wing built. and test thrust.

 

[The Fopster]

Wow. Good luck! If you get it to work that will be epic!

If you have 20 micro motors and you know it clap your hands!
below are the specs on this type of motor:
http://www.us.diigiit.com/chaoli-cl-0408-coreless-motor-4mmx8mm
This motor is one of the smallest we carry and can be used for really small robotic applications like a small UAV. Despite its small size, this coreless motor is very powerful and can easily be used with a small tail propeller like the one we sell. This motor is rated for 2.6 V. By connecting the red wire on + pole and blue wire on - pole, the motor will turn clockwise.

Features

• model: CL-0408
• shaft diameter: 0.6 mm
• body diameter: 4 mm
• body length: 8 mm
• voltage: 3 V to 5V
• nominal voltage: 2.6 V
• cable length: 30 mm
• weight: 0.5 g
• torque: 0.08 g.cm
• no load speed: 42000 RPM
• no load current: 35 mA

What this means:
so all 20 motors are 10g weight. and pull 850mA for 10

So I might get 25-30 with a 450mAh Battery? This will have 2 servos for control surfaces. which draw 100-150mAh average... so 1.1Ah
If I have to, I can always use 0820s with whoop props... size goes to a 60-70" wing. si 6-8 mins with a 150mah... something seems off...
There is no data on Amperage if it has a prop though.

AHAHA - That's too much.
Should I create a title then? Hmmm how about "if you have 20 micro motors and you know it clap your hands!"

 

[Vimana89]

Those micro motors are beautiful. If this flies, it will be sweet

Lol, that’s good!

 

[FoamyDM]

I'm worried they will produce as much thrust as they weigh only. I'm thinking of how to make the size right but stupid light. I suspects it will using Skinimoa techniques.
