I finally got around to test this, and boy is it fun! The regulator parameters are a bit off for this type of usage, but after some tuning I got it working quite well. If anyone is interested, here is what I used (same for pitch and roll): Kp: 150 Ki: 70 Kd: 2 and I increased the angle/rate limit in...

I would recommend to keep the two blue leds towards you at all times in the beginning as this makes the copter go left if you push the stick left and vice versa. Also try to use small stick inputs, even if the copter is drifting quite fast. It should slow down by itself if you do not move the pitch/...

Glad to help, happy flying!

It seems to me like you are missing the numpy package. I encountered similar problems when I installed cfclient with the reps on my ubuntu machine, depending on how you install the deps they might or might not install deps of their own. It seems like pyqtgraph did not install numpy for you, I think ...

Im just now playing with my CF2 and I am experiencing strange LED behavior too... if I start the plotter the CF2:s led:s change behaviour, the two front ones (LED 4 and 1) are constantly on (expected from LED4 because of RX/TX but not from LED1, heartbeat...) and LED 3 is completely off, but i can s...

Crashing is a natural part of flying the CF2 I think, although the crashes are getting fewer the more you fly... :) The M1 is used both as a heartbeat and a low battery indicator (see http://wiki.bitcraze.se/projects:crazyflie2:userguide:index ), when the battery is low it changes from blink (heartb...

I am having problems putting my CF2 into rate mode (attitude is the "normal" mode). I can see the settings in the cfclient, but the checkboxes are grayed out. Is there a parameter i have to set to be able to access rate mode?

Yeah, I agree, it is an awesome little machine! So much fun flying, and with little to no damage when crashing, at least compared to my big quad! :) I have not yet encountered any low-battery related bugs (it has dropped out of the air, but that is to be expected!) but I have encountered something t...

Always interesting to hear what resources other people recommend! When i started to get serious about programming I started with Learn Code The Hard Way, http://c.learncodethehardway.org/ they have, among other languages, a course on c and one on python, and everything is free if you use the on line...

I just tested everything on my ubuntu machine, and it works great!
