Hello.I'm starting this discussion since there's a lot of confusion and lack of knowledge about PID settings and control theory, so, you can find here a table with several different frames,…Continue

Rui Manuel Cravo Marques replied to Randy's discussion ArduCopter 2.5 released!"Hi Lars.
Couldn't help notice your STAB_I at 0.100. Leave it at 0.000 and instead use the RATE_I at 0.010 (both on Pitch and Roll). Also you may try to reduce a bit your STAB_D to 0.100. Try this to see if it gets more controlable.…"
Rui Manuel Cravo Marques replied to Randy's discussion ArduCopter 2.5 released!"Hi Emile. I had noted before via kmz files that even after lock the gps needs about 20sec to correct the position. We should always wait about 1min after lock before arming, or home position will not be so accurate and may go to 10 or 20mts away,…"

Rui Manuel Cravo Marques replied to Stephen Gienow's discussion Motor Dips in Flight, Connections Soldered"I'm not saying it was a cutoff voltage, however, even with a fully charged battery, if it has a low discharge rate, it can have a very high voltage dropout causing a cutoff if you have a let's say 3.3v threshold protection. The best thing…"
Rui Manuel Cravo Marques replied to Randy's discussion ArduCopter 2.5 released!"Hi Marco, I have a Rabbit GPS and I uploaded the config file, the problem is that this GPS doesn't have a flash to store it, so it stays only in RAM wich looses configuration as soon as the battery goes flat.
I had it working with the APM and…"
Rui Manuel Cravo Marques replied to Stephen Gienow's discussion Motor Dips in Flight, Connections Soldered"Hi Stephen, have you checked the temperature of motor and ESC after that happens, or leave it running with motors at about 70/ 80% but tight to a base to see if the motor stops and check the temperature to see if that ESC / motor is getting hotter…"
Rui Manuel Cravo Marques replied to Randy's discussion ArduCopter 2.5 released!"Lars, I believe your videos are most welcome, and I'm pleased to know you are making good progress :D reminds myself, and yet I am not anywhere near experienced as Jason, or Chris or Marco, and small things make me happy too. I still get…"
Rui Manuel Cravo Marques replied to Randy's discussion ArduCopter 2.5 released!"Hi Grips. I've been checking your roll graph and it doesn't look too far from mine, so I think it must be something with the expo curves from your radio, but I could be wrong. Also, have you tryied with STAB_D_S at 0.5 ? In the radio what…"
Rui Manuel Cravo Marques replied to Randy's discussion ArduCopter 2.5 released!"good to know :D now you have to tweak it for your personalized frame. It looks bigger and heavier than mine, so I guess you will have to rase the P parameters a bit. Again regarding that "expo" symptom, check in the parameters list how…"
Rui Manuel Cravo Marques replied to Randy's discussion ArduCopter 2.5 released!"Hi Grips. Please post your settings and what motors and battery you're using. My hexa is a bit smaller than yours, but I'm using much smaller STAB P values and I'm happy with it. I'm in version 2.5.4 but don't think…"
Rui Manuel Cravo Marques commented on Jean-Louis Naudin's blog post APMRover 2, a fun UGV project for full autonomous recon missions..."Thank you Thomas. But can you tell me if the firmware is making use of the other gyros and acc ?"
Rui Manuel Cravo Marques replied to Randy's discussion ArduCopter 2.5 released!"Nice :D welcome to the sky"
Rui Manuel Cravo Marques commented on Jean-Louis Naudin's blog post APMRover 2, a fun UGV project for full autonomous recon missions..."I have a question. Why do we need Oilpan for ardurover ? Besides the mag and the gps do we need any of the other sensors ? The gps may be connected directlly to the Ardupilot Mega board as well as the mag, wich connects to I2C bus.
"
Rui Manuel Cravo Marques replied to Randy's discussion ArduCopter 2.5 released!"Hi Pete, you look to be flying the same frame as I am. My test showed that regarding RATE_P this configuration can use a very wide range - I'm using sunnyski x2212 motors wich should be identical. I sticked with a lower RATE_P of 0.1, RATE_I…"
Rui Manuel Cravo Marques replied to Randy's discussion ArduCopter 2.5 released!"Chris, can they call it Ardupilot Mega ? (a pirated version more expensive than the original lolol)"

- well, not so far ago, I became interested in this matter, without knoing there was already so much acomplhisments in this area. I was fully unaware of the quadcopter existence and was at the virge of building my own first arducopter starting with nothing else than my arduino and accelerometers and a couple sensors more. Now I'm completelly hooked to this.

My First Hexa Flight
Posted on May 12, 2012 at 8:30am 5 Comments 6 Likes
Here is the first flight of my first hexa :D used software AC2.5.4 wich gave an excellent flight (I had 2 yaw twiches) Loiter still needing some work in software or PID. I think throttle rate is a bit higher causing those ups and downs. Alt hold seemed to work better with version 2.2. RTL worked pretty well and that option to disengage auto landing it's great. Thanks…

The Relevance of Propellers
Posted on January 10, 2012 at 12:52pm 14 Comments 6 Likes
Hi again. Latelly I've been testing some different propellers on my quad and checking the main differences between them. For my emax gt 2218 930kv , my 3S batt and the 1500 / 1600 weight, I was using those cheap 12x4.5 props. I even bought 12 pairs for $25 or so, and one thing I can tell you about them... FORGET ABOUT IT. After 2 crashes from wich I could not tell if it was a motor or prop problem, I decided to test other props. I started thinking that too much flexibility would have a…
