Flight controller for basic RC quadcopter using brushed dc motors
I'm organising a camp to encourage high school students to take up STEM courses..... and I'd like to have them build their own RC quadcopters. I want the course to have a minimal fee.... so the quad should be INSANELY CHEAP.
The quad should be able to do just one thing:FLY.
Also, durability is not an issue.... just one or two flights should be sufficient.
1)Can someone please suggest a design using brushed instead of brushless motors? (Simply because they're cheaper)
2)If there's any way I can build a flight controller using off-the-shelf components.... please share your ideas..
3)I have no idea about how to make the remote control/ RF transmitter....... is it the same as that of an RC toy car remote control?
(how do I encorporate controls for four degrees of freedom?)
4)I've come across some lovely designs where the frame is made out of paper or cardboard.... so that's not an issue.
5)Since a number of kids are gonna be flying their quads in close proximity to each other, should I allocate different frequencies? (in order to avoid interference)
Help in any form is welcome.... I'd love to hear from y'all....
Thanks in advance...:)
