Re: [Paparazzi-devel] Lisa/M2 for manual quadrotor flying

[Felix Ruess]

Hi Gerard,

yes, you should be able to only fly in manual without a GPS...

But make sure that the bat voltage is in valid so it doesn't go to a failsafe mode...

For debugging I would recommend to connect telemetry (either via USB->serial cable on the desk or a real wireless modem).

If the modes and bat voltage are correct, I would suggest to look at your motor controller config... what kind of ESCs are you using and are you sure they are properly set up and initialized?

Hope that helps,

Felix

Hi all,

I have a TBS Disco quad which always had a DJI Nazav1 fitted, but the controller failed and is dead.

I'm trying to replace it now with a lisa/m2 I have lying around. In this setup, I don't want autonomous flight, just manual stabilized control. There are no peripherals connected, only the receiver (no GPS, no telemetry, no battery indicator, etc). 

I changed the config file so that it doesn't monitor batt. voltage and changed the flight plan, so that there's no initial GPS check.

In my first attempt, it only takes off 5cm off the ground and then hovers at 5cm. Applying more throttle does not cause the quad to rise higher. I even applied 100% throttle once and it stays at the same altitude.

Am I overlooking something?  Shouldn't I have full control in this mode and be able to fly it as a regular quad?

One motor does get hot, so it's possible the entire behavior is caused by one prop not delivering the power required, but if that's the case, I'd expect the quad to flip or at least have some more aggressive or random behavior than a consistent 5cm hover?

Batteries, motors, props are exactly the same as used before on the quad and definitely has sufficient power; with this setup it should already hover at 40% throttle.

Rgds,

Gerard
