Looks good! mine used to look a bit like this when it was "new"... hehe 

now after many abuse and repairs it is no more clean.  

Questions for you... why the velcro under the ESC?

I now mount my ESC on the dome side, they are a bit further from the PDB and they get more air to cool them...

Sonar cable doesn't look like it is shielded... you may want to improve that before flying...

Otherwise. GREAT job! post another picture of the side if you can. 

Oh and remember to post another picture in 3 months from now... I bet it will have changed a lot! :) 

 

Enjoy!

Dany: Thank you for your encouraging feedback. I appreciate the tip on the sonar cable shielding. Thats a great idea and I will fix this before the next flight I have flown the copter quite a bit and posted a video of it crashing after losing a motor which prematurely failed due to poor manufacturing Funnny you should mention the mounting of the ESC's I had planned to mount them differently to get more air. I would love to see a photo of your ESC mounting.... I will understand the not so clean now angle :-)

Yes I wondered who would pick up on the velcro under the ESC. Two thinjgs made me do it. First I did not like the way the large capcitor in the ESC would not allow the ESC to sit parallel to the centre frsme hub edge. Secondly I wanted to keep the ESC off the sharper Edge to protect the surface mount components from vibrating against the frame edge and give a little cooling gap on the rear of the ESC. I also have a lot of velco left over from many large datacentre computer installations in recnt years.

Very neat! But I'd suggest mounting the sonar further from the body, as shown in the manual.

Very clean wiring indeed !

I wonder how your sonar alt_hold will perform.  If you're not getting a smooth sonar alt hold, try mounting the sonar away from the esc's like other already said.  Here you can read why : http://diydrones.com/forum/topics/fixed-my-sonar-alt-hold

 

I would be curious how your althold performs with your sonar mounted as it is.

Many thanks for the tips and link to the sonar inteference forum post. I will be sure to make some adjustments at least to the sonar wiring i.e sheilding plus signal and power filters on apprpriTe feeds. The sonar on my frame looks close to the ESC but is on long plastic extenders about 2" from the nearest ESC. However I need to change the connection wires.

I have had some more time to tidy up the wiring on my arducopter quad while sorting out some motors issues.  So I have posted up a photo of the top side of the quad.  Might be useful for new builders as a reference. Dany will probably want to see an after photo of this in a few months too :-)
