Hi Guys,

I have bought a new hexa copter frame, the Tarot 680 pro with canopy. I have Turnigy Plush 30a ESC’s and will use a 4s Multistar 10c lipo and Naza FC.

Frame: https://multirotor-parts.co.uk/wp-content/uploads/2014/10/54311jpg.jpg
Canopy: http://tarot-rc-heli.com/image/cache/data/TL2851_02-500x500.jpg
ESC: http://www.hobbyking.com/hobbyking/store/__2164__TURNIGY_Plush_30amp_Speed_Controller_w_BEC.html

Main question, where I’m a going to mount the ESC? There are so many discussions on the Internet between high skilled people with a degree (in electronica) but contradict each other.

In my opinion I have two options with pros and cons:

ESC below the motor (pros):
  • More space left main plate
  • Less heat in the canopy
  • Good option for people who says only lengthen power leads and don’t lengthen motor leads
ESC on main plate (pros):
  • Many people says it’s better to lengthen the motor leads instead of the power leads
  • Less weight on arms
  • Cleaner design
  • No power leads and ESC signal cable together in the carbon fiber tube
  • Rule of thumb people Internet: don’t lengthen the power leads over 12 inch. Not necessary when ESC on main plate
  • No magnetic field in carbon fiber tube
  • People Internet, don’t mount your ESC close or below the motor
  • No need for lengthen the ESC signal cables to FC
How do you solve this in practice?
 
I placed my escs where the motor is, ran the wire through the tubes, and did not have any issues. It was really stable.

You cannot trust everything you read online. Here is a video of mine.
 
I was hoping you should reply Ringolong. I know your videos ;) Your video/frame/configuration is my starting concept for the new build.

I also want to run the wires through the tubes but Internet made me crazy. I think I will return to my first idea how to build this setup.

Questions:

1. Do you have 3 wires per tube? So power leads and ESC signal wire together?
2. Maybe stupid question, but did you twist the power leads to reduce the magnetic field in the tubes? In other words, carbon fiber and power leads, isn't that a bad combination?
3. How did you lengthen the power leads? Just with bullet connectors or are there better options like stripping the ends and solder them?
 
Thanks for watching my videos :)

1. Do you have 3 wires per tube? So power leads and ESC signal wire together?
1. Positive
2. Negative
3. ESC signal wire - Heatshrink where the cables connect(http://www.amazon.com/gp/product/B00X5IAZJK?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00)

2. Maybe stupid question, but did you twist the power leads to reduce the magnetic field in the tubes? In other words, carbon fiber and power leads, isn't that a bad combination?
I did not twist, and never had any issues.

3. How did you lengthen the power leads? Just with bullet connectors or are there better options like stripping the ends and solder them?
I soldered longer wires and then used 3mm bullet connectors. Soldering is always best, but bullets made it more convenient for me.
 
Sorry to respond to such an old post but I just started this build a few weeks ago. It sounds like there is no issue with running the power wires instead of the motor wires. But, I just got mine this month and the kit came pre-soldered with the bullets on the motor wires and the power pre-soldered to a distribution board instead of the upper board. So, it's pretty clear they have set this up to NOT put the ESCs under the motors. However, I can't figure out where on the body I'm supposed to put the ESCs and still have room for the legs to retract. I'd rather not undo all of the soldering if I don't have to. Any suggestions?
 
You should be able to mount them underneath the body. I just liked mine under the props where they would stay cool.

Soldering is not bad at all. I would personally just solder longer motor wires in place.
 
Yeah, I went ahead and extended the power wires on tonight. Under the body is a little cramped because of the battery board. I'll experiment with it though. I might end up putting them on the top. Thanks for the suggestions.
