Howto Inflight ACC - Calibration in MultiWii 2.0

Method A: The Failsafe method (if you have an aux vhannel assigned to arm your copter).

Preparation: uncomment #define InflightAccCalibration

Step 1 :- Copter on ground, Motors off:
- Stick Combo: Throttle + low yaw left + pitch foward + roll right
-> Copter Beeps 2 times: Function activated (do it again to deactivate: copter beeps 3 times)

Step 2 : get airborne and level copter either by trimming TX in hover mode or level it in acro mode.

Step 3: When copter is leveled (no drift) switch off engines while airborne: copter beeps.

Step 4: Switch Engines Back on and land: copter beeps long and new Offsets are stored in EEProm

Step 5: Start again and notice the new new calibration (Important: If you trimmed in level mode: take back all trims on your TX or you will propably crash)


Method B: Using the passthrough function

Preparation: uncomment #define InflightAccCalibration, assign passthrough to one of you aux channels.

Step 1: get airborne and level copter either by trimming TX in hover mode or level it in acro mode.

Step 2: activate switch "passthrough"

Step 3: land and deactivate "passthrough": copter beeps long and new Offsets are stored in EEProm

Step 4: Start again and notice the new new calibration (Important: If you trimmed in level mode: take back all trims on your TX or you will propably crash)

ps.> this function overwrites the ACC/Trim multiwii is providing, feel free to optimiye I bz hand with the usual stick combo after auto trim.

New airframe almost done

My new airframe is almost done, I just need to mill the new Landing legs and the new constructed motor mounts and it is ready.



The new cage is nearly indestructable and has a MK mounting ring ontop, so I can mount the GPS and the cam up there.

Some minor updates: Gyro Calibration / new GoPro Case

Due to the rainy and windy weather right now, there is not much time to fly and have fun.
I made some short flights in the past days but nopthing serious.

I had some pretty rough days in december. I was pretty occupied with my Taekwon-Do club and hat not much time for the ncopters.

But I managed to do some software tweaks:

I finished and perfected the acc autocalibration and I finally managed to restart the gyro calibration routine at startup if the copter has been moved durin calibration. Pretty handy...


Second small projekt was the revision of my fpv gear. I was unhappy with the bold camerahousing and decided to spend some money for the original GoPro skeleton case, this case is lighter and has the opprtunity to connect the video out plugs while the camera is in the case. Abolutely worth the money.
This way the camera is protecteds way better than beforce. Only drawback: The camera has to be mounted upside down but the gopro is capable of rotating the image live so I still can do fpv and all recordings are rotated too. *sigh*
Especially the lens is now secure. And besto of all it looks way sleeker now.

My FPV deck is now complete. You can attach it in 20 secondes and convert an action Quad to a fpv gear in seconds.
