"Hi Simon, I had the same problem. Levelling my hexa with Mission Planner or using in-flight trim didn't work. What finally worked was using the fields AHRS_TRIM_X (roll) and AHRS_TRIM_Y (pitch) in the Advanced Parameters List. These values are…"

Hello. I was wondering if anyone may have some suggestions for tuning this machine. I have attached a video in which you can hear how the motors are behaving. Once I switch modes from stabilise to…Continue

Peter Seddon replied to Simon's discussion Is there a trick to leveling these days?"I had the same problem on two 'copters. The one would not respond to leveling using CH7 or redoing the accel calibration and I finally reloaded the firmware, erased the EEPROM and started again - success. The other required just very careful…"

i had the seem problem .it only started when i put my 2.5 in the plastic case .

Mike Mac replied to Simon's discussion Is there a trick to leveling these days?"I just got 2.9.1 installed in my Y6 APM2 and it was level after doing the calibration. I did the calibration with the board removed in the plastic case. That way I could easily get it level in all axis. I had only the USB cable connected – No…"
Mike Mac replied to Simon's discussion Is there a trick to leveling these days?"I have the same problem but it is not as bad as yours. I think that we will have to wait for the next firmware update before that is fixed.
I am going to upgrade my old APM2 on my Y6 today so we will see how level it comes out. With a Y frame…"

Can not get my artificial horizon to level in the Mission Planner anymore.I have carried out the "Accelerometer Calibration" in the "Configuration>ArduCopter Level" section of Mission Planner and no joy.Then I did the in-flight trim as per https://code.google.com/p/arducopter/wiki/AC2_Flying and still no joy.The artificial horizon is about 15-20 degrees off level and I have to compensate quite a bit when…See More
Simon commented on Daniel Chote's blog post My QAV500 quad progress"Interesting to hear about your experience. I have a QAV500 as well. It has been okay so far except that it does not respond terribly quickly when increasing throttle to slow a descent. Very difficult to slow down in a descent. I was…"
Simon replied to R_Lefebvre's discussion Fixing Yaw (particularly for Tricopters)"Thanks Felix. That was helpful.
cheers"
Simon replied to R_Lefebvre's discussion Fixing Yaw (particularly for Tricopters)"Hi Felix. Sorry this is offtopic but regarding the QAV500 - how did you connect the ESC leads to the APM? Did you just connect them directly to the APM or did you modify the leads at all? cheers."
Simon posted a discussionConnecting ESC directly to APM2.5
A newbie question: are you able to connect power/signal leads from all 4 ESC directly to the APM2.5 or do you need to cut the power wires from 3 of the ESC's before connecting?I noticed that when connecting via the PDB, power only comes from one of the ESC's.CheersSee More
Simon commented on Jordi Muñoz's blog post Announcing APM 2.5!""Any chance of a pic of how the new 3DR Radio connectors should be configured? There seems to be an extra wire on the adapter that was shipped with the APM2.5 v the APM2.0"
OK - found the answer…"

Simon replied to Simon's discussion Pulsing of motors"OK - just stumbled upon this:
"Parameter: THR_RATE_D is 0.02 by default, but the noise of the Baro sensor can cause issues. If the value is too high you will see bad oscillations or pulsing of the motors. Once the THR_RATE_P value is dialed…"

Hello. I was wondering if anyone may have some suggestions for tuning this machine. I have attached a video in which you can hear how the motors are behaving. Once I switch modes from stabilise to RTL, you can hear the motors pulse as the quad ascends to the preset altitude before commencing descent.direct link coz embed code does not appear to work http://youtu.be/UT5SOexFv_4 And here is a picture of the beast with video setup…See More
Simon replied to Michael's discussion Can somebody help me tuning my quad?"That crash at the end...could it have been caused by low voltage? I know my quad goes a little crazy when the voltage gets too low."
