This is the result of my "indestructable" quadcopter design blog.
I dont know how well it crashes it yet but after 2 test flights, it flies very well! I need to do some PID tuning as the arms are quite short. They are 450 size heli tail booms that I cut for no other reason but to make the quad smaller and see what happens. Any PID tuning recommendations for shorter arms?
On to the nitty gritty. All the carbon fibre is 1mm thick. It was cut with a jigsaw using a fine metal blade and it works really well. The motor mounts are made of 4mm perspex and were cut using a hole saw. The landing gear is also 4mm perspex cut with a jigsaw and bent with a mini blow torch. I never realized how strong perspex actually is till I started messing around with offcuts! its unbreakable! under huge stress it just folds but never breaks in 2.
The total mass without battery is 630g and with 2200mAh battery 828g. I actually have no idea if this is light or heavy for a quad?
2x 100mm x 300mm x 1mm carbon fibre: $10.79ea
4 x 450 heli carbon fibre tail boom: $2.40ea
Screws, nuts, bolts: $8.00 nylon screws are quite pricey!
Perspex 300mm x 300mm x 4mm sheet: $10.00
Total: $50.00 Not Bad =)
