I have a long way to go, but I have PLANS that have kept me awake recently. FC and telemetry next, but I want to design a mount for it, so in a fit of rabbit hole diving I recreated the lower plate in CAD last night and from there I can derive the mount.
The mount I have in mind could be laser cut from acrylic, so I just need to mooch over to the nearest makerspace and zap it with a laser.
But I need to get all the electronics first so I can lay it all out and avoid sticky tape and cable ties as much as possible.
The frame of my 2" 3D printed quad has been almost completely redesigned…
No changes to the electronics at all.
(motor wires are now zip-tied since that photo)
My Pixhawk 4 gear arrived the other day, and I am just checking out the current draw. It fluctuates with the GPS LED, but seems to peak at 130mA @ 4S nominal voltage (about 2W regardless of voltage, rising slightly as voltage increases).
There’s no telemetry plugged in yet, so that will add a chunk. I don’t plan on having an RC controller, instead flying with a game pad.
I like to think that this is one of the few drones in the world with leather as an integral part. I was casting about for an insulated pad to mount the PDB on, when my eyes fell on my scrap leather bag.
We’ll have to see what the thermal characteristics are, so if I smell a hint of the barbecue I will have to rethink.
I am now pondering changing the landing gear pads for a hand-sewn leather version
Seeing as how my flight privileges have been revoked until further notice I’ve been rummaging around in my various bit boxes, and I’ve gone 8bit oldskool. For some reason I’ve been feeling nostalgic.
The quads in the picture are both made from the old Hobbyking SK450 (inspired by the DJI F450 ) frame, the one on the right is the HK Dead Cat conversion.
Both are using the KK2.1 flight controller. These flight controllers are a bit long in the tooth by today’s standards. They were cheap as chips back in the day but nowadays they seem to be commanding a higher price. And for some other strange reason they are very popular in India (?)
The KK2 board caters for many configurations, from single rotor up to octocopter including the much maligned Tricopter and V-Tail Quadcopter.
My two examples up until recently were still running the old V1.5 of the original Hobbyking firmware. This was somewhat buggy and even though Acro flips and rolls were possible the response and resolution was lacking. So to that end I’m going to experiment with some third party firmware’s which offer much greater performance.
I’ve put these two quads together because I wanted something big enough for me to see while flying LOS Freestyle ACRO.
I also intend to resurrect my 500size Collective Pitch Quadcopters, again for some LOS Freestyle Fun.
You know that feeling you get…when you’re repairing a crashed drone and you’ve got it all reassembled but when you test it there’s one vital thing not working…
Then when you get time to test fly it, travel to the flying location, get everything setup, then realise you re-installed the camera upside down…and your allen keys are at home
