I think I may have been calibrating my ESCs wrongly!

I wonder if this is a common mistake, or even a mistake at all.
I'd REALLY been struggling with my Quad drifting and simply being horribly unresponsive.

So, I decided to start all over with my config and I watched a video of a guy calibrating his ESCs that chagned everything for me.

Here's how I used to do it.

1. PROPS OFF!!!!
2. Uncomment ESC_CALIB_CANNOT_FLY
3. Power up, upload the sketch.
4. Wait for all the beeping to stop.
5. Comment ESC_CALIB_CANNOT_FLY
6. Reset and upload sketch.


What I just did:
1. PROPS OFF!!!!!
2. Uncomment ESC_CALIB_CANNOT_FLY
3. TX on, Throttle FULL.
4. Power up, upload sketch.
5. Wait for 2 beeps.
6. Throttle to MIN
7. Wait for Three beeps and a long beep. (This seems to happen by itself after a timeout, so be sure to move your stick BEFORE it happens)
8. *** DON'T RESET ***
9. Comment out ESC_CALIB_CANNOT_FLY
10. Upload sketch.

Seems that I'd inadvertently let the calibration run without doing a throttle up-down, and also when I reset the NanoWii, it was running the calibration AGAIN before the new sketch had uploaded, thus erasing any calibration that I would have performed.

I also cleared the EEPROM and recalibrated my Mag and Acc.
Took it out, trimmed the TX a little in Acro mode, switched to Angle and BOOM steady as a ROCK even with the default PIDs. HOORAY!!!!!



I want to reverse the Yaw control though as it seems back to front to me. Pulling RIGHT on my throttle turns it CCW... no, don't change YAW_DIRECTION to -1 as it just reverses the YAW correction and sends it into a mad spin.

Do you have a Quad or a Tri with a yaw servo?

If a Quad then reverse the direction of the stick output in your transmitter's setup.
In the Multiwii config.exe the stick values should increase when sticks move from bottom left to upper right. So the Yaw stick values be minimum when stick is to the left and maximum when stick is to the right.

Hah! Yes. my TX is so basic,mi forgot about the row of inverter switches.
Will give it a spin in the morning, my lipo is recharging on my solar powered rig right now... Yay, green credentials!

Not that I have had problems with this , but I'm going to try and see if there is a difference
