Aluminium Weaver Mk2

anton.pryamostanov · May 4, 2019, 5:26pm

Following the success of its predessor, today started to assemble Aluminium Weaver Mk2.

Have few interesting component layouts in my mind.

So far welded frame weight: 97g

Not bad for 500mm frame.

Hi @anton.pryamostanov,

It’d be nice to see the finished built.

Today’s progress:

anton.pryamostanov · May 8, 2019, 9:12pm

Todays progress.

Frame 90% ready.

anton.pryamostanov · May 11, 2019, 9:56pm

12000 mAh 3sp1 with balancing port ready:

anton.pryamostanov · May 12, 2019, 9:44pm

Frame fully ready.

Complete frame weight: 200g.

anton.pryamostanov · May 12, 2019, 10:05pm

And starting assemble.

anton.pryamostanov · May 13, 2019, 9:57pm

Wiring.

anton.pryamostanov · May 14, 2019, 7:13pm

Todays progress.

Unfortunatelly it seems that ESC is cooked. I did a mistake by not checking it right after unpacking. After all soldering it did not power up. Will have to order new one.

Weight is same as previous version (1700g including battery), however new drone has 12000mAh battery vs 5500mAh in previous. Thus expecting flight times around 25 minutes.

That’s starting to look like a pretty serious rig now!

TB_RTK · May 15, 2019, 5:28pm

Wohaa… that looks like a problem ready to blow up.
I am impressed by the dimmensions of your balls

anton.pryamostanov · May 15, 2019, 5:35pm

Before I put a payload on this battery, and a fire starts - can you tell me why would it cause a fire?

TB_RTK · May 15, 2019, 5:39pm

Unprotected metal surface is my main concern

anton.pryamostanov · May 15, 2019, 5:43pm

Is it going to oxidize/corrode under current?

So far on previous drone the switch didn’t corrode. Are these connections for indoor usage only?

I am flying mostly over the sea and seashore.

TB_RTK · May 15, 2019, 5:44pm

it only takes seconds for the lipo to blow up if its shortcut.

anton.pryamostanov · May 15, 2019, 5:46pm

oh that thing. I see. This should not short, I put some pvc tape between unconnected terminals.
I will put additonal PVC layers though. Thanks for advice!

anton.pryamostanov · May 15, 2019, 8:35pm

How about this, Elon Musk?

(plugged not fully because I need to test rotation direction)

Thank you for keeping us updated!

You are comming up with dangerously creative solutions. I know that from myself, but wise men and women do not do the errors others did before… . Its a good idea to rethink your own ideas and drop them if necessary. And yes, it is hard to drop your own ideas.

Some remarks:

Your battery looks extreamly dangerous. Not funny.

You should at least add some serious insulation between the conductive parts. If they will ever get in touch (which will happen, you can be absolutely sure) the lipo will explode.
I personally would never ever do such thinks with lipos.

I also would solder the esc motor connections. Its safer and will safe at least 1 min flight time through reduced weight.

I’m looking forward to see it fly!

anton.pryamostanov · May 16, 2019, 8:06am

Thanks for the comments.

I will cut the battery terminals small to the size of attached wire terminals and add insulation for each of them.

Later I will solder the ESC-motor wires - that was my initial plan. Just I suddenly realized XT60 has exactly same size as Sunnysky motor plugs - and wanted to try that
