That could also be your problem. Another thought....What size battery do you have S3 mA? C15 or lower? Maybe the battery can not handle the load. |

I will try to do a couple reinstallation with ESC calibration, Eeprom reset en IMU calibration.
The strange thing is that its not always the same motor. Could it be related with the fact that I'm using a 18C battery? The motors get a sort of nodge just before they stop. |

Hi.
Before i go and spend some more on a new magneto, can somebody please tell me if i can check the magneto or the oilpan to pinpoint my problem? Problem is that on apm_compass test i get all values zero and nothing changes. I have checked the connections, i measure 4.7V on vcc, and continuity between all 4 pins of magneto and corresponding pins on oilpan. The solder blob is also checked and measured to make sure it doesn't short anything. Do i need a new oilpan or a new mag? thanks |

Please everybody with magnetos and gps test Hein's latest code. ... except for John who'll be flying his release #139 forever, I think. |

Valuing from what you have posted your lipo should work - unless it's old, worn out or badly charged (different voltage in the cells). Good luck! |

I did a full reinstall of everything, ESC calibration, firmware, Eeprom reset, calibration of tx and accels. During the ESC calibration of right motor it gave a nodge but didn't stop. Calibration is without APM so I would suggets ESC????
Did a test flight and it worked for about 30 sec.Then back motor went out and ... crash. Pffffffffffff No more props. A have a ESC from a different brand and will test all the motors with this one.If this is OK Iwill change all the ESC's with another brand an check for a 25C+ battery. Hope this works. If not, I'm going for something else and sell everything. |

Your battery is 2100 MAh and 18C. That means it is capable of 2.1*18= 37.8 Amps current. You have 4 motors which is 9.45 Amps per motor. Now, KDA description says: Quote:

I would suggest perhaps taking a look at the ESCīs programming. It could be your lowvoltage cutoff, timing or brake setting that is wrong.
I dont know those "SP" escs, but if they are anything like a Turnigy/RCT/OEM/Hobbywing, you should have these settings: Brake: off Batterytype: Nimh (to get lowest possible cutoff voltage) cut off type: Soft Cut cut off voltage: low (or disable, if possible) Start mode: Normal Timing: Typically medium or high (I run the KDAīs on High) Music: OFF Governor: Off Always use some form of audible/visible Lipo alarm to tell you when your battery is low. |

ONE thing I need to remark: allthough I am very sure that I have set all parameters correct my magneto showed exactly 22 1/2 degrees into the wrong direction . (Hein, this is probably why it drifted always to the right ?? Does this reflect a wrong matrix programming between X and + config? I am flying X and magnetos upside down pins front. I suggest to test with a real compass and the artificial horizon of the configurator: -Phil |
