‘The Wingtip’ | 10-pound commuter

[City-Blade-101]

reminds me of @whitepony somehow

Honestly, i think this log thread is almost an archive of recommendations at this moment

This thread was dedicated to “U1: Wingtip”
But during the work on parts, I’ve scraped almost every idea i had at the beginning and want to start all over again in 2021, with “U2: Winglet” as it was suggested

@NullReference

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.

I think, that is the reason of my versioning problem explained here:

So, stay tuned for new thread in the nearest future, I have a lot of interesting stuff to be done in January:
Upgrading the Ender

Going from avr to arm

And other not-esk8-related DIY

If this was in europe id have bought it in a heartbeat.

Just weighed my coyote build, 8.5lbs! I’ll post pics tomorrow. Happy new year.

Damn it, Must’ve been a fluke on the kitchen scale, bathroom scale says 12 pounds.

3d printed mount ?
With what filament ? How does it hold up ?

[Alpacaslapper]

Haven’t ridden it yet, just finished assembling, I’ll let you know. This mount is a prototype; caliber 1 trucks. It’s petg, all bottom layers, 0 infill pattern, only worried about motor heat at this point. I think I’ll print a cooling fan, found a post on endless sphere where they claimed the fan cooled the motor 20*c

Also need to reprint the bottom cover piece, it’s short a few mm.

Be careful with it, petg might not be strong enough to resist the vibrations

I’ve experimented a lot with 3d printed mounts and in my experience single mount just doesn’t work, the plastic does flex a lot resulting in belt skipping. What works is a dual motor configuration with the two mounts connected with a threaded rod or something, that way it is rigid enough. However, the motor heat is still a problem. It doesn’t necessarily melt the mounts, but the plastic mount doesn’t dissipate the heat like aluminium, resulting in overheating motors really quick.

This motor is open, huge holes on both ends, I’m going to print the fan this weekend. This board is only ridden maybe two miles at partial throttle. Maybe a tensioner pulley allowing a more loose belt would be best to eliminate skipping.
