I just checked and my favorite skate weighs in right at 20.0 lbs

Just to be pedantic, that’s a picture of a split scimitar winglet on a 737. Not a normal wingtip
Coincidentally winglet is a great choice for this project as winglets like the one in the photo are predominantly used by short haul airliners as they improve climb performance at the expense of induced drag. This trade off is only worth it for the really short routes. And that’s why larger airliners use raked wingtips.

Been busy this week, so wanna share some thoughts.
Currently watching videos about stm32 programming, bc I wanna move further then good old avr thingies. So yeah, the brains and remote of the wingtip will be stm32-based. The data transmission will be organized on the HC-12 modules, that work flawlessly for me for a long time with no issues.
The antispark and receiver are going to be on the same PCB, which connects directly to the rear of the VESC. This design leads to a good space-management, very clean look and the wires floating around minimized.

Could you make like a balsa or foam mount, and then just skin it in CF?
That seems like it might be a pretty easy DIY.

It does look awesome.
Do a kick flip.
Are those the ride unlimited hub wheels?
Do they sell them separately?
Yes, here you go:
Not cheap tho. 220 euros per wheel.

Wow.
Thanks.
That is pricey as hell.
I will keep waiting for you to post a video of the kick flip

Guys, i need suggestion on the battery connector. Xt60 seems an overkill for 1p p42a, so… Deans or xt30?
I would use XT30 over a Deans connector but if 10 lbs is the goal, you better just solder and heatshrink and seal because it’s less metal. And I’d run 16AWG

16 awg wires are already in the cart

PSA:
When soldering on a live battery, remember to completely finish, wrap, and seal, one wire before taking the tape & insulation off the other wire.
And oh yeah tape the ends of EVERY wire that you’re not CURRENTLY working on.
It’s not overkill, it’s being smart.

Actually, I’m going to stick with xt30. That 1.7g piece of plastic will make battery detachable.
I’ve checked the aeroflot (main national airline) website and it states that I can carry-on two batteries less than 160wh. So the wingtip is airplane-safe. At least, in Russia. Makes sense to add 1.7g 
Also completely abandoned the hot-swap idea. This just increases weight when I can simply charge this pack up to 75% in 1 hour.

A bit of update post if someone is interested
Plans have changed drastically during this weeks. Not only I’ve realized I’m too low on budget to spend even 150$ on a battery and other stuff, but also noted that I have useful stuff laying around.
The first reply was “why not use lipos?” I will, eventually. The only problem is I don’t have so much space to fit 4x 3s lipos, so I thought “why not just use good old 6s config that I’ve been running for more than a year?” So, battery capacity drops to 111wh (6s lipo) from initial 144wh (10s1p 42a) but weight remains the same: 750g. On the other hand, my old 5065 270kv is 100g lighter than new 140kv, so that’s a good deal. Moreover, I’ve used this bitch at 50A and it was not even getting to ”hot” state. So power output will be more than enough, 1250 motor watts, much better that 10s1p p42a ~900 watts.
So I’ve restored stator windings, and soldered a good silicone wires to the motor. Now it feels much more better than it did previously. Currently trying to improve shaft to can connection, because original one really sucks.
Also tried to modify two chargers from 10s and 12s to 6s without any success, so I have to buy one that is cheap, light and powerful enough to call it somewhat “quick” charger.
Also, going to try glue new plywood deck in the next few days. If it is going to work well enough (I mean, weight less than planned 700g) then I’m all good to call this thing a wingtip. Otherwise - hello fiberglass, my new friend.

You can make a 6s from a 12s bms by connecting the last 6 balance wires to no 6 of the bms i believe atleast thats what ive heard.
And moreover, I’m not a fan of pre-built bms.
Passive balancer + charge port + cccv charger serve any needs in battery charging.
