Motormounts with ESC32 for a new Hexa

[joebar.rc]

Christof, that is looking very good. The ESC's seem to be protected very well in their casing.
.... One day I must own a CNC myself, amazing what you can do with such a tool.

Thanks for the comments.

If you send me the drawings, I can cut you some parts till you get your own CNC.

Thanks for the good wishes.
Your proposals where very logic but gave me a headache due to limitted space. While mounting the first ESC I felt like double lefthanded with twisted fingers and arms.

I selected a 1.5mm2 powerwire to keep the resistance as small as possible. But it is a bit thick to handle. Whats your best guess for the powerwire diam?
I planned to use a 2nd 330mF 35V low esr @ +- center of the powerline. Can I combine the 470(ESC) and 330(Powerline) or should I use the same capacity?
To see the leds I took the signalwires to the bottom.

Nice Idea with the acrylic standoff. I never cut that before but will give it a try.

Nice Build!

May the Motor wires should go in to the side as you can easily cut them in a crash and its hard to replace so short cutted motorwires afterwards.

AWG 16 should have some safety margin, AWG 18 shold do the trick also on this Motors.
To combine different capacitors values is no problem.
Acrylyc is nor my favorite, its too brittle and heavy, but i dont know, can work good sure.

Thanks for your proposition Paul.

I was thinking of guiding the motor wires from the side or from the front and add some connectors. But then I decided to go straight from top. If there should be crash, it's a lot of work anyway.

For the powerwires I decided to go inbetween. AWG 17 equals 1mm2.
Then I added every 10cm 330mF capacitors and drilled the wires nicely.

Takes a lot of time, but I hope it pays with good results.

It progresses slowly but it progresses.
BTW when do you expect the new batch of boards?

uh tihs is a late answer, sry.
i like your aproach, cant really comment if all those uF are really needed, but you should be absolute safe

[Flyduino_Paul]

you may should think of precharging the caps over a resistor before you connect the lipo, otherwise i can imagine there is lot current during first connect.

Hi Paul
Never mind about the late reply. Thanks for the precharge hint.

What if I wanted your same frame ?? it's beautiful

[chschmid]

Thanks for the flowers. It may look nice but I do not know if the setup flies well. I can send you the CNC files if you want. then you can cut the parts. I was using 1.3mm CFK and the spares/tubes from paul.

Oh, and here is the new gimbal.
