Christoph replied to Chris Mitchell's discussion Can quadcopter motors be mounted upside down ?
"I'm pretty sure that these points:
- no aerodynamic pressure over the arms pushing the drone down.
- lifting points above CG (good stability)

are not valid (there are a lot of other discussions about this here). there is no force that can push the…"

Christoph replied to Christoph's discussion Pusher configuration for Copters
"I found only one company that does this, I wonder why no research institutes are doing this:

Christoph replied to Richard Kennedy's discussion Waterproof quad??
"I wonder if it is really needed to have a completely closed case.. has anyone tried to just make the components waterproof to e.g. fly in rain? (of course this probably won't work if you are actually landing in water)"

Hi there,I'm right now reading a bit of theory on how to design my DIY quadcopters, and came across some interesting things.First, this thread:Pendulum Fallacy and QuadcoptersThis is very interesting, but I'm not sure if anyone had success and how…

Christoph replied to bitman's discussion How to attenuate the copter reaction on throttle,pitch and roll
"hey there,

the documentation of this project is really horrible, I agree
I have to admit that the openpilot people do a much better job on this, if the documentation would be better I'm sure there would be a lot more ardu* users

anyway, what you…"

Hey,Can anyone explain to me what THR_ALT_I is for? I don't get it..I've set my THR_RATE_P using sonar so that the copter reacts accurate to obstacles, but I'm a bit unsure how ALT_I affects the behaviour, also THR_RATE_D, is this used to dampen the…

Hi there,On http://code.google.com/p/arducopter/wiki/AC2_LoiterMode it says that speed I is not user editable - however, I've got it in the mission planner and can set the values.On this…

Hi there,Can anyone tell me what the difference between ACRO_P and RATE_P is in copter behaviour?ACRO_P is the angle per second, and RATE_P the desired motor thrust, I'm a bit confused, aren't both affecting the same behaviour?How do you distinguish…

Does anyone know what the difference between Arducopter Pids and Arducopter Config is?Trying to configure my first CRIUS AIOP board with megapirate 2.7 and somehow, although I've got I-Gains at zero, the copter always maintains the angle...I'm also…
