"the answer was disconnecting OSD and Telemetry. There was an intermittent spark (from what I can figure) that caused the eeprom to reset. So far this has gone away by checking all wiring (first by disconnecting all extra gear to the APM) and…"
HelloI'm having a major problem with my 3DR APM 2.5 unit. It has been working fine for the last year+ until the last weeks where the unit keeps resetting itself completely wiping out any calibration or other params I may have already done.This is…
"This is what happens with prop slip my friend. Totally mechanical failure and not APM related.
As Andre K. pointed out, its related to washers, torque on the prop nut and or something coming loose due to vibration.It happens, you live and you learn."
"Short answer is yes it can fly with one prop or motor out on Y6, X8, Hex, Octa configs.AFAIK its not a coding issue, but mainly of the amount of control the multirotor has with the failure. Y6 with single broken prop flies no problem with less yaw…"
"I built a custom Y6 with an APM 2.5 running 3.1.5I've followed the motor layout on the wiki using layout Y6B and it flies beautifully.
Bad Gyro Health message is not good at all - which means if even after calibration you still get that message,…"
"He said he gets just over an hour per 12000 3sp3 packProp failure sounds really strange, you mean your prop breaks? how many rpm do you get with your motor setup? what type of prop are you using?"
HelloAfter looking at the code for 3.2RC4 its still quite unclear what the proper prop direction is to use the V-tail config for the V-tail style multirotors.The code specifies, // front right: 70 degrees right of roll axis, 20 degrees up of pitch…
"Hey John, so I've figured out what I needed to modify to get it flying - after testing a bunch of different parameters.
It has a big tendency to lean forward as you said it would.This is my motor mix for it (having removed front YAW completely)…"
"thanks for letting me know - feeling pretty confident about what I've plugged in so far using the original set of changes you added plus some stuff I had to add and modify or that is missing to work in 3.2rc4.I'm having a bit of trouble figuring out…"
"Thanks for answering! I've already patched in all the changes you've made into 3.2rc4 however at the moment I'm just trying to make sure there isn't anything else I'm missing.Did you ever ascertain what caused your crash? "
"There is a possibility here that's super easy to overlook. depending on your board of course.It could refuse to arm because of voltage alarm could be miscalculated. This is why you can arm when using Ground station through USB and not out in the…"
