Current Sensor

I got my ACS758 current sensor today



I will install it at the powerline between my Lipo and my Power distropution, I will be able to measure the current that is coming out of the battery pack and in combination of the voltage over time, I will be able to calculate the mAh that I have used out of the Lipo and can save the Lipos more precisely.

Turnigy 9X mod

I finally bought a Turnigy 9X.

Sadly the vendor on eBay ripped me off and I had to repair the TX, he reverses the voltage and fried a lot of the circuits. I replaced som voltage regulators and the TX is good to go now.

I immediately flashed the TX with er9X custom firmware and now I have a perfect TX for my nDROiiD.
I use it with my TR6A V1 which provides a SumPPM sadly there are only 6 channels on the RX but it will do the trick for now. I will try to get a sumppm encoder to use all 8 channels that are available on the TX.

Vacation in Danmark

I am back from my windsurf and family vacation in Hvide Sande, Danmark. I took nDROiiD with meh and made some Spectacular aerial photos in superwindy conditions. The copter was very flyable and stable despite of the wind. I am very satisfied right now. It were also my first flights with my new tx: Turnigy 9X with er9x mod.

nDROiiD: FPV Cloverleaf in acro mode: ACTION!

Now this was some serious fun.

The Copter felt great and was so responsive, looking forward to more like this...

A short flight movie with the new MPU 6050

I did it: First flip!

Hi,
I finally pulled my self together and accomplished my first flip:

After some tuning (higher RC Rate) I am pretty used to the maneuver:

Altough an backflip does not work because of some broken front motors :-/ .
I used my crappy Keychain cam because my GoPro is far to expensive for that kind of maneuver.

Now I need to improve my throttle handlin, to loose less height:

Maby warthox can help:

less throttle while in midflip ;-)

Cloverleaf antenna done

I built my first cloverleaf antenna for 5.8gHz FPV TX. Testing will happeb as soon as possible.

Look here for details

First passenger on FPV goggles

I gave my best to make him puke, but it did not work.

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.

GPS finally working

Mit the newest DEV of the MultiWii Code comes a working GPS routine, I have now fully working Return to Home and Position Hold.

I did some test flights and I am pretty impressed by it.

Updates and videos coming soon

Spring...finally!

Let's celebrate it with some FPV footage:

aaaand

good to be back...
