But this will not help if a motor or a prop is in the wrong position = it will flip on takeoff.

Hi Cris

Did you trim stable mode?

1. Land and disarm.
2. Give full Throttle and than trim with the other stick.

Re: Failsafe auto leveling.

Tested failsave in the field.

Works great except the default throttle value of 1450 was a bit to high - it started gaining height instead of landing.
So i switched the TX back on and got back control to land it.

I think, we should lower the default FAILSAVE_THROTTLE to 1300 (or even lower).

Ok, I can confirm that the Orange Spektrum RX switches to sending 1000ns on throttle if the TX is switched off.
All other channels are flat on my DSO.

BUG (v2.0): Buzzer only working if #define VBAT is enabled

Hello!

I just found that you can only use the buzzer via AUX2 (pin D12) to locate the quad in the field if you enable "#define VBAT".
Without VBAT it's simply not working on pin D8.

Maybe someone can fix this.

Even with disabling the internal pull-ups there are also the ones from the BMA. So in parallel with the 2k2 you get 1,8 kOhm. This is still ok - you don't need to cut any traces.

Re: What's all this I2C failure stuff, anyhow?

All the pull-up resistors in sum should be near 2,2 kOhm. R sum = 1/(1/R1 + 1/R2)
I disabled the internal pull-ups and placed the resistors the way you can see on my picture.
Of course you can place the pull-ups everywhere between VCC and SDA and VCC and SCL.
For me the way on the pic was the easiest.
