nicolas grunbaum commented on Jimmy Oliver's blog post Walabot. Has anyone seen/experimented with this?
"Looking at the api from walabot, in one example i found: 
// Walabot_SetArenaR - input parameters
double minInCm = 30;
double maxInCm = 200;
double resICm = 3;

Probably the range is around 2 meters. "

nicolas grunbaum commented on AKRCGUY's blog post Invertix 400 - The World's First 3D Fixed Pitch Multirotor!
"Wow, it's been 2 years i do that but never thought someone would say it's the first fixed pitch.... 
Come on. Warthox did it first with multiwii and ultraesc moded. Then I did it with naze32 and simonk esc. 

What invertix is using? "

"Hi Jason and Co, I don't know if it's a problem but I got this when compiling with the latest 2.1.1 from git:

nicolas grunbaum replied to Geir Engebakken's discussion Auto-leveling problem in 2.0.55
"Hi, Just fly with autolevel for 20 secs. Land, and disarm the motors. Reapeat 2 or 3 times, always disarming. This way it saves the auto trim."

nicolas grunbaum replied to Jason Short's discussion Arducopter 2.1 release
"Hi Jason, I just tooked a look on the changes. The code is cleaner, cool! 
I will make a test on the afternoon if it doesn't rain. 

I'm still using my modded log.pde file (using the old style but with the data values according to mission planner).…"

nicolas grunbaum replied to Marco Robustini's discussion ArduCopter V2.0.54 - Altitude bug with Octa config?
"Have tried to compile with arduino, the 2.0.54 firmware but using the log.pde from 2.0.50? I used to have some problems with log and altitude (mostly sonar). Your log has wrong gps altitude data. "

nicolas grunbaum replied to Jason Short's discussion Arducopter 2 stability patch
"Well, I don't understand anymore. My hexa has suicidal tendencies. It keeps crashing. 4 props dead. 1 landing gear. I must say I'm starting to give up. Don't know why it does it. 
Well, I will try again."

"Jason, I have something strange with mine. Sometimes it tries to come to me even I told him not, just for a glith. Then normal. And a problem with my logs. look at this:
 
I'm going to do some more test.

nicolas grunbaum replied to Jason Short's discussion Arducopter 2 stability patch
"Hello Jason, I'm looking at the new code. I see you add a stabilize_roll2 and stabilize_pitch2 but I don't see where it is use.
When I search the stab_roll (or pitch) I found it is used in the arducopter.pde file. Is something missing? Or roll2 and…"

nicolas grunbaum commented on Arnt-Inge Hansen's blog post Hexa flying
"I tried accel alt hold, I think I'm using it. It works ok. Still having some issues with baro alt hold. Sonar alt_hold works perfect. Maybe I will try the independent bec for sonar.

nicolas grunbaum commented on Arnt-Inge Hansen's blog post Hexa flying
"Hey Arnt! Nice hexa. I see the diferences between our config, your values are higher than mine. Maybe the reason is that I use 12 inch propellers (that give more lifting power). 
 
Glad it works great. Did you have the accel alt hold enabled or not?…"

nicolas grunbaum replied to Jason Short's discussion Arducopter 2.0.51
"Hello Jason, 
 
I'm looking at the z_dampener code, I think that maybe to let user adjust some factors, maybe fullDamp is too high or too low. Maybe let users tune this value a simpler way than compiling the code each time (maybe if everybody finds…"

nicolas grunbaum replied to Jason Short's discussion Arducopter 2.0.51
"Hi Jason, here is another log with some more testing on alt hold. When in sonar range, all ok, when in baro range, it oscilates a lot. I have the default alt hold settings (0.4 and 0.02). I have oscilations and can't keep the altitude. Maybe there…"

nicolas grunbaum replied to Jason Short's discussion Arducopter 2.0.51
"Hi Jason, I'm trying it and works allright. Alt hold is really nice, although I have a small issue when I'm over the sonar limits. I found in my log that when I'm higher than 7 m the sonar send some bad data, a lot of spikes and APM can't get…"
