Im new in this and wonder if the arducopter (w/6 engines) can fly with one engine failure. Maybe it will decend and make a "soft" landing, or will it go crazy and crash?Continue

Magnus Skogmo replied to Wesley Versfeld's discussion Most stable Arducopter version?"I had a similar suddenly altitude drop this yesterday. hard touchdown but no serious damage. the situation seem to be exact similar to what R J Hamlett is describing. my reaction was full throttle (still in loiter mode) and the hexa…"

Despite of the "Ready to FLY uBlox OK" message I did a successful calibration (level routine / Accelerometer Calibration) in MP 1.2.47. It seem to be a…"
Magnus Skogmo replied to Dave C's discussion Arducopter Tuning Guide"Never heard (on forums and wiki) about this approach to the problem, but it is the only that looks logic for now.
The answears on your questions are NO, NO, NO and Im using uBlox.
I have observed that when I going to LOITER SIMPLE mode, the…"
Magnus Skogmo replied to Dave C's discussion Arducopter Tuning Guide"Have you any idea whats wrong with the loiter. Sometimes the copter overshoot. Getting bigger and bigger circles around the target. Have tried to reduce loiter_P (from 5,000 to 3,000). then the circles getting slower but still growing in size (have…"
Magnus Skogmo replied to Randy's discussion ArduCopter 2.9 / 2.9.1 released"Ok so if I, after tuning, get the following values on my 3DJ Hexa B with 880 motors:
Rate_P 0.2500
Rate_I 0.4720

... can it be the correct settings? (Im way of the values in the tuning "Arducopter tuning guide" here on…"
Magnus Skogmo replied to Dave C's discussion Arducopter Tuning Guide"I get "happy" values way off the values in the tuning guide (and the most of you other too). I get
Rate_P = 0,3200
Rate_I = couldn't find a value here with sense. Nothing happend, but I will try outside later.
Rate_D = 0,0230

I solved my similar problem by changing from shielded to unshielded cable between the camera and OSDMinim. I have no idea why it helps... (I would have guessed that shielded would be best; but not in my case...)"
Magnus Skogmo replied to Lito P's discussion Random motor surges"Im not an expert so I wondered: Do I have to upgrade PPM encoder if I using PWM?
I have APM 2.5 bought November 2012 and running ArduCopter 2.9.1. I have temporary solved my problem by changing to 11ms FRAMRATE on my Spectrum DX8 Transmitter."
Magnus Skogmo replied to Lito P's discussion Random motor surges"I solved the problem when I changed transmitter FRAMERATE from 22ms to 11ms (better described few posts above).
Is this an interesting findings in the work to try to permanently solve the problem?"
Magnus Skogmo replied to Paul Thunder's discussion Strange Motor Behaviour on ArduCopter (Quad)"Se this tread. Maybe relevant"
Magnus Skogmo replied to Lito P's discussion Random motor surges"I had exactly same symptoms with APM2.5 and 2.9.1. Using Spectrum DX8 and PWM. I think I have solved the problem when I went to the Transmitter SYSTEM SETUP menu and changed FRAMERATE (from 22ms) to 11 ms. Have tried a lot of times now without…"

"What is the difference between an i2C ESC and a regular ESC? Please explain."
Luke Olson replied to Magnus Skogmo's discussion Engine failure"What about an octocopter configuration? Does that require I2C ESC to fly with a failed motor?"
