ArduCopter 2.7.1 will become available on Mission Planner and in the downloads area shortly. This release contains a few important bug fixes as well as the first implementation of the MPU6000 sensor-fusion code.
Detailed changes are in the commit log. Here's a summary:
- Preliminary support for MPU6000 on board sensor-fusion (DMP)
- AP_Limits: Experimental "bounce" mode, for smaller spaces (LIM_RECMODE)
- Bug fix for yaw error buildup on takeoff
- Fix in Auto mode for failsafe handling
- Fixes to 3-axis camera gimbal code
It's normal for my heavy quad! :P
I asked Jason to take a look at the autotakeoff and autolanding routine.
Hi Marco, thanks for the info cant wait to test this myself when available :-)
keep up the great work.
major discussions on this for a while now in a few other posts and back further in this thread
Hello, if I have a wobble in my 3dr frame in stablize mode can this be a direct result to a bent shaft? I have ordered the 3dr motor shafts and was wondering if it will fix the wobbling or is it part of the 2.7 release?
You may have RATE P too high... try to lower it a bit. If you have bent shaft, spin the motors on the ground and put throttle to 0 and see if there's a motor stopping much quicker and not "loose" like the others. Another way is to check the motor temperature. A bent shaft will most likelly cause motor to heat more. Also spin it by hand and check if it "brakes". If the shaft is heavily bent, it will also cause more vibrations on the arm to wich is attached.
I know the shafts is bent, I went into altitude hold about 7m heigh and the quad dropped like a rock out of the air bending 3 shafts about 15 degrees.
hmmmmm are you talking about motor shafts or motor arms ? Sorry for the confusion.
I am talking about the shafts.
Arms is still fine.
Spent some time trying to setup my clone F450 with the APM2.It hovers now. But seems to have this funny wobble issue. I have been dropping the Rate P down to lower the effects of this. Currently at 0.09.
The wobble seems to cycle every one second. Almost like the quad is shivering every second or other second. Should I keep lowering the the Rate P?
I think it is probably related to I rate so you should try lowering it. Low frequency oscillations are usualy due to too high I rate. Maybe I am wrong so don't jump me.
ok, I will try lowering the I rate. I have not touched that yet.
