Title: Warthox inspired 400mm quad project
Post by: chris on October 30, 2012, 22:34:00
First I used LibreCAD to create a frame design. Inspired by Warthox but smaller. Then I printed it on copper clad board using an inkjet so I would have an accurate pattern to follow. I drilled all the rounded corners then cut the rest with a cut off wheel. I can't easily express how much I hate cutting thick tough nasty fiberglass PCB.  >:(

Next I used KiCad to create a circuit board for the electronic bits. Printed on a laser printer with magazine paper, ironed on, etched in my home-grown cupric chloride (love that stuff). This is a temporary design because I don't have any 90 degree headers which means this one is going to be messy but I want to fly now.  :)

Drilled and painted board.

Power distribution. Silicon wire is heavy. I started with PVC insulated wire for testing and the quad was 10g lighter.

Putting together the final bits. I intentionally left the copper on the frame. It's painted with enamel clearcoat to prevent oxidation.

As it flies today.

Weight is 396g without battery (was 385g with PVC wire  ::)).

575g AUW with 2200 mAh 25C lipo. Around 20 minutes flight time.
