Little known fact, if you push a runner bean seed up your nose the moisture will cause it to germinate, and expand.You wont get any beans though just  two black eyes. :o

Nothing permanent yet, but given I am just using the PC screws to check component placement and such like. Just velcro at the moment to hold the esc';s onto the arms. KK2 FC will be mounted on top plate with vibration damping grommets.

Whole thing is 933 grams which I was surprised about. Will just need to solder the battery connector on Monday and then I can start radio setup, esc calibration and KK2 setup.

Looks good to me  ~~ not sure how you did it but your picture thumb nails seem bigger than the actual picture or the same  :shrug:

Looking good mate. Have you flashed the KK2 with the new v1.5 firmware?
Here';s some KK2 settings to get you started, its the same setup as mine so they should be ok. The default settings are ok for hexa and octocopters but you can turn them down for quads.
If you want it more responsive you can take the stick scaling up higher.

PI settings.

Roll + pitch:
P: gain: 45
P: Limit: 100
I: gain: 25
I: Limit: 20.

YAW.
P: gain: 60
P: Limit: 20
I: gain: 30
I: Limit: 10

Mode settings:
self level: AUX
Link roll and pitch: yes
Auto disarm: yes
CPPM enabled: no

Stick scalling:
Roll: 30
Pitch: 30
Yaw: 50
Throttle:90

Misc settings:
Minimum throttle: 20
Height dampning: 0
Height D limit: 30
Alarm: 0
Servo filter: 50

self leveling settings:
P gain: 60
P Limit: 60
ACC trim roll: 0
ACC trim pitch: 0

Hope this helps.

Hi huys,

Gaza7,
Yes, next time I will have to upload slightly larger photos. I figured out the smallest pics from my phone turn out to be pretty small.

Rokit5,
Thanks for those settings. Hopefully I';ll be able to power it up tonight so I can input those settings. I';ll find out what firmware it is then. I do have the USB cable and have been swotting up already but everyones help here has certainly speeded up the process and made me feel more confident about which direction I am going.

The whole "bird" is only held togther with short PC type screws at the moment. Worse still are the screws holding the motors onto the arms are so short the thread only just catches.

RCtimer did email me to say it';s Chinese new year holiday now and that they would send after that.

I ordered equivilant replacement screws off ebay so hopefully they will arrive very soon.

Tonights objective will therefore just be to:

Get battery connector all wired and soldered in.
Setup my DX6i radio (airplane mode, new model).
Bind to receiver (once receiver plugged into ESC1).
Throttle calibrate each ESC.
KK2.0 firmware determined and possbly upgraded to v1.5.
Configure KK2.0 to choose model and configuration.
Check Pi settings against above.
Check motors are spinning the right direction.
Check right props are on the right motors.
Secure Battery with Velcro and check centre of gravity.

...then I';ll have to down tools until the proper screws arrive...... :frantic:

Once proper screws arrive I can figure out a way to mount the FC to the top plate. I think I can mount the FC to nylon spacers, then the bottom of the spacer mounted to a square sheet of perspex with vibration damping grommets. Then the whole thing foam pad mounted to the top plate.

Seems like quite a lot to do! But as I suspect with a lot of you, putting it together and getting it, "just right" is half the fun!

If I';m well enough and you need any help tonight mate, you have my skype details.

I';m sure you';ll sail through it though, a man of your calibre ;)

Well, screws arrived (enough of them from ebay). 

Soldered the battery cables
Binded (bound?) the RX to my DX6i.
Calibrated each ESC and ensured motors spinning right way. 2 weren';t.
Tied all cables back.
Cleared space for battery between the plates.
Programmed the KK2 with the values above.
Figured out how to set up the flaps button on the radio to the Aux channel and to now control self level.

Hooked it all up and then I realised all my lipos are pretty much at 11.0 volts dead.....

KK2 says safe mode and I can';t power it up..... so basically, forgot to charge my lipos!!  :-/ :embarrassed

So... charging them now.....

But for the meanwhile... here should be a bigger pic.

I will only put the props on once I am convinced I know how to arm the KK2 out of safe mode...

She flies!



It';s still processing and it looks short but she flies ok. Will be looking to practice more when I have calmed down!

Looking good ~~

It';s a great feeling when you have a bunch of bits and turn it into something that flies :cool:

Great stuff..that s what i have the 450........and now have a dji330....love the 450 but it does feel like a bit of a bus compared to the agile 330 now!!! :smiley:..i think the 330 is better for practicing tricks,flips etc.....these quads are addictive!

guest325

Looks good, bit different to a heli or plane - I love ';em, for fun you can';t beat a Hubsan x4 or a Twister quad - the 450 is so much more stable but you can fly the Hubsan in your living room when the weather is cr4p! Have fun,
D
