  • I too have the attopilot 90a. I use it in conjunction with a lipo alarm to test accuracy. So far I feel, it's giving better than average. I give 3.5 out of 5 for me. 

    I use this because I am using MegapirateNG & Crius (as it came bundled with my ARF quad). I would like to try an Ardupilot board or Pixhawk as a comparison sometime, but have no plans to buy as I'm just going to fly with my setup for a while and not worry about purchases. It can be never ending.

    Also, I feel happy to use the official ardupilot power module (as the attopilot 90a seems double the price) with the Crius and just snip the end plug off and locate the inputs on my flight board.

    Downsides to my Crius AIOP board:

    - save trim & Auto trim only seems to make flight control worse

    - no regular updates

    - no datalog recording

    - no auto tune

    - hard to find cheap board enclosures to protect from propswash

    Upsides to my Crius AIOP board:

    - It works (eventually)

    - It forces you to do code

    - can hack & use the cheaper sonar module (with average results)

    - It was a bit cheaper

    I think someone said "Do what you can, with what you have, where you are." I'm enjoying where I am with quads, using what I have available.

  • @ Gary:

    Is it usefull for you?

    Yes I'm using it, does what it says on the tin.
  • Thanks for your answers !
  • Well would it be better used for telling the instantaneous current draw.

    I've got one, but to be honest I find the voltage sensor built into ArduPilot is just as useful in gauging how much juice is left in the battery. After all, voltage, not current, is what the ESC's use to set their cutoffs, so all you want to know is how far you've got until they kick in.
