Optimising the QuadYCopter
There's a few things I'm trying out to get the QuadYCopter as stable as the QuadCopter is; Three Blade props 4S Battery Shorten the front arms Restore the PID values to default Custom code. By far, the biggest change / improvement has come from using Three bladed props and a 4S battery. Some might [...]
QuadYcopter Maiden Flight video
There's a few different names that might be applicable like a Y4, Inverted V-Tail, Y-Copter but I think I'll call it the QuadYcopter and it flies! All I had to do before this video was reverse the direction of two motors and it flew better than expected considering the lengths and angles are all eyeball [...]
Timelapse GoPro extended by external power source
Ran the GoPro from about 2pm till 8pm on the upstairs balcony. I'm not sure how long the GoPro battery would last so I hooked it up to a LiPO 2650mAh battery via a uBEC. I checked the charge before and after and it had used about 40% or about 1060mA. I think the [...]
Tuning for auto-level – MWC Quad
According to the instructions on multiwiicopter.com the mid and endpoints need to be set properly to ensure auto-level works properly. I hadn't bothered much with this except to make sure the throttle travel was low enough to arm the PARIS board. This is probably why I've spent so much time stuffing around with trimming flights trying [...]
MWC Quadcopter – Cramming in the ESCs
These photos show the frame starting to come together. The bottom of the CF plate shows each of the four ESCs are held in place by 2mm cable ties. There's not a lot of room left on the top of the board after the ESCs and power distribution cable is laid down. On top of [...]
Quadcopter Scarab – Power Distribution lead
These photos show the power distribution lead made as per the instructions that come with the Scarab 12 – Quad-X Euro frame. The wire is 20 AWG from HobbyKing. About 15mm of the silicon jacket is stripped from the end of five wires per polarity (red & black). Then the bare wire of each group [...]
QuadCopter SCARAB – Motor Mount Retainer
These photos show the retaining screw cut to 7mm and how it penetrates one quadrant of the 12mm aluminium tube divided up by the motor mount. Cut to the right length, it doesn't intrude far enough to cause concern with rubbing on the wire from the ESC to the motor which is routed internally along [...]
QuadCopter SCARAB 12 – Assembly part 2
The frame looks well laid out, light weight and just plain good looking. 20AWG is used to connect to the 2213N 800Kv Brushless Motors with just enough left hanging out the end to connect the four speed controllers ( TURNIGY Plush 12amp (2A BEC) BESC ). The only thing I'm unsure about so far is the [...]
SCARAB 12 – Quad-X EURO Build – Motor Mounts
I'm going to try using 1.5mm cable ties on the motor mounts. Seemed to work fine on the Tricopter and in the event of a crash, there might be some give before things get bent.
Canola from the air
It seems every second field is full of Canola around Shepparton at the moment. Here's a few quick ones I took on the way to the Mammoth Scale Fly In at the Valley Radio Flyers. I did lose the quad once, quite deep in the canola field and thought I could be searching for [...]
