3d printed 0603 brushless whoop!

Get's about 3 min. of flying when murdering the batter down to 3.6V after rest. 2.5 min. is more reasonable at 3.7-3.8v

I first printed the original design but wasn't super fond of the cam built in cam mount. I requested one without the mount to use a regular canopy and the designer posted a fixed version a day later fit perfectly with the canopy and mount linked below.

I rebuilt it a day later with the canopy and all fit perfectly, the canopy is quite sturdy and weights about 0.9g.

(The last pic in the gallery is from the version with integrated cam mount, was 0.5g-1g lighter and came in at 22g.)

All printed in ABS and held up to abuse very well - if it breaks i'll probably reprint it in PCABS but I didn't feel like swapping filament :)

I used 17000kv as I got them cheap during a sale - if buying new I would go with the 19000kv instead - can't say the 17000kv are lacking in power for indoor apartment flying tho.

Flies really well with Betaflight 4.xx purple copper preview build with all new filters :D

Updates

I swapped the cam mount for this one: https://www.thingiverse.com/thing:1906041 but cut off the sides as i didn't need them, leaving them on should be fine tho. Note that I put the cam mount under the ducts so its (fc-cam mount-ducts).

I updated the linked cam mount in the parts list.

You may need to cut off a little from the top too (not sure as I re-used the mount I had from another build where I had it cut it off already).

This mount raises the camera a little more so it floats above the board and shows less from the ducts.

I also had diagnonal video lines which were solved after making sure the cables from the cam are not touching the FC anymore. I guess some sort of interference.

Tip - put a piece of heatshrink on the left and right part holding the cam to make the cam fit snug (unless you printed it already with a snug fit)

STLs?!

A few people asked about the stls - they are linked under misc parts below :)

Betaflight Config Diff

This is using Betaflight Nightly #1198 build with some new stuff, should apply to bf 3.5.1 the same tho.

I deleted some irrelevant stuff like osd and transmitter/receiver settings.

It's mostly based on mocking bird v3 pids for the ur65 but with some tweaks.
