Arducopter 3.2 Warning

Posted by Rob_Lefebvre on May 29, 2014 at 12:31pm

Just wanted to put out a warning to everybody, that you should not be testing any of the 3.2 Release Candidates for Tradheli until I say so.

At this time, I have not flight tested 3.2rc1 or rc2. I have been doing bench testing, and they likely will not fly at all.  I am working on the 3.2 code, getting it to a point where it's flight ready.  I'm hoping that I can keep up with the multirotor 3.2 release schedule.

At some point, I may ask for beta testers to try a 3.2 rc, but I will make this clear when it is time.

Thanks,

Rob

    I've been flying a lot on 3.1.4.  It's rock solid except, on one of my two helis, the heli doesn't reset to armed yaw on RTL.  I don't know why and haven't been able to fix it.  But other than that, it's really handling quite well in Loiter, Auto, and Stab.

    When I upgraded to 3.1.3, the upgrade process messed up a few of my params.  That was bad.  Now I don't take anything for granted.  I reload from a known good param file, and recalibrate the Accel and compass on each upgrade.  I also double check the params.  Maybe overkill but small price to pay.

    Thanks, Rob, for looking out for us.  I'll help test when 3.2 is a little more ripe.

      That armed yaw on RTL, I believe the the problem is that you don't have enough of a pause before the final descent for RTL.  There's a parameter for this, that sets a pause before it comes down slowly.  It's during that time period that it yaws around, and if it's too short, it gets cut off.

      Thanks for the confirmation of 3.1.4.

    Hi Rob, Setting up a largish heli for Phil C,(re recent email from phil r).. What version of code do you recommend running at the moment?

    Cheers

    Steve

    (bet it's warmer here than there at the moment!!)

      That's a surprisingly difficult question for me to answer.  I actually haven't flown the stable release codes for a while.  I am currently flying a personal development branch based on 3.1.0 on all my machines.  I haven't flown any of the 3.1.2+ codes.  These contain mostly back-end fixes, which are well tested on multi-rotors, and should not have any effect on tradheli.  But given the details of your particular project, I'm extra cautious.

      I assume that if there were any problems with the 3.1.2+ releases, that somebody would have let me know.

      Sorry if that sounds like a flaky answer, but I'm a very cautious person, and especially in your case want to make sure you know all the facts.  I'm building a heli similar to yours for somebody else, and will be using my development branch.  But I'm not sure if you'd want to do that.
