Hi I am building a large octo I need help to configure the setup
My equipment are:
Wookong-M
Hobbyking 30A esc's with SimonK firmware
Avroto 2814/11 motors
4S 6000 X2
AUW 6.5 Kg
Props 12x3.8 CF
DX-8 Tx/Rx

Does this conf. looks ok?
Do I need to do any changes.

She flew fine for 6 min, landed and tried again but the esc temp was 140F
I tried lifting off again and she quit half throttle. I repeated and she quit again.

Any suggestions?
The camera gear and acc. amount to 3.5Kg


Cheers

6.5 kg + 3.5 kg or 6.5 total? 140F seems no to be so high imo for 6.5 kg tow but it deppens on your weather temp outdoors.

www.farnell.com www.rs-components.com
these were from farnell. 40x40 and made them a bit smaller to precise fit the esc, took of two rows of ribs.
make sure not to cut of all the heatshirink so the smal plate comes lose, leave some on the sides where the wires are. 3-5mm each side
have used heat conducting tape. applied it to the esc AND the heatsink, rub it on well with the back of a screw driver or something round and smooth.
and then put them together, this makes the best bond so de don not come off!!

Thanks Sebas. I used Artic silver for my sinks on the BL's
Will that do?
Also would be easier to mount the sinks directly on the fets instead of on the plate?

Once Artic Silver is on is for ever. I trie to pry the heat sinks off an old PCB and had a hard time.
And it was held on on only 3 fets. My esc's have 6 fets.

Cheers
