Note: just as the release was going out an issue was found re support for the all Camera Gimbals on the APM1s (it doesn't work) and with 3 axis gimbals on the APM2 (2-axis works ok but not 3). If you're one of these people, please wait for 2.7.3 which will be out shortly.
UPDATE: 2.7.3 is now in the Mission Planner
Functional Improvements over 2.7.1:
As per usual PIDs are optimised for the 3DR/Jdrones quad with 850 motors and 10" props. If you're using more powerful motors/props and are seeing bad flight behaviour in stabilize, start by turning down Rate Roll P in 25% steps.
There is still some question on whether the default Roll/Pitch Rate P (0.175) is high enough (it was 0.185 in 2.7.1) and also some people feel the Throttle Rate should be higher (currently 0.300 but some say 0.330 or even much higher would be better).
Please feel free to report issues you find in the discussion below and/or add them to the issues list.
Thanks and enjoy!
Test load with arduino, something similar happened to me, but apm1.4. I happened to v2.6, not downloaded well directly from the planner code.
and try the version that I run.
Congrats to the Dev Team on this release! I spent a hr testing it on a XAircraft DIY Hexa, really positive results.
Loiter, was awesome. About a 2m Box, after 4 minutes slight drifting.
Stabilize was great as well. Quite stable, 0 problems.
Auto, this mode was weird. I set a 3 way point plan, and wrote the way points, and then I loaded the way points and I got 15 way points. I have never ever set a 15 wp plan on this APM before. Took me a couple of times to get them erased.
Next flight, the hexa on auto would go to Home and skip the rest of the (3)wp's. I confirmed the "auto" mode was correctly set on the radio.
I have done 0 PID tuning, so out of the box I am pretty happy with the results. Keep up the good work. Cheers,
ok, thanks for the report. I'll check that out.
On the APM2, I've found that sometimes it doesn't detect that it's inserted but if I jiggle it around a bit it's ok.
I used another computer and it reloaded 2.7.2 and all is well now. works on mine again now too.
Thanks for all the help Chris.
reloaded from a friends computer and all is well again.
Thanks for the help Norman.
We've just pushed out 2.7.3 to the MissionPlanner and the download area. 2.7.3 is really just 2.7.2 but with a small fix to the camera mount code to resolve issues that primarily APM1 users would have.
I forgot to mention that we needed to upgrade the eeprom version from 118 to 119. What this means is that your eeprom will be wiped out and you will need to do your radio, etc set-up again. Really sorry about that but it couldn't be helped and we actually haven't increased it in a long while...it's probably for the best.
Hi Randy, I should have mentioned, its the apm2.5 version with on-board dataFlash ic.
I'm sad to say this but I've just had 3 consecutive bricks on my XBee telemetry... :-(
I enabled 2.7.3 firmware CONFIG “# define DMP_ENABLED ENABLED”, APM2 still crash when it staring :-(
Firmware 2.7.3 is awesome, thanks guys for the great job, it's the first time my hexacopter is working so nice and huge improvement for baro, it's like my copter is flying with DJI :)
I'm using standard PID, no tweaks (Except for Alt Hold)
My configuration :
- Mystery 20A Blue Series ESC with Simonk firmware
- Turnigy L2210C-1200 motor
- Graupner E-prop 9x5 propeller
One thing remaining is Gimbal, I didn't manage to make it working with APM2 under firmware 2.7.3, and wiki page is not up-to-date with instruction to make it working
