Can you please post pics of your plan/ idea?

Solder all the ESC power wires to a single point (+ve to +ve and -ve to -ve). Then solder a male XT connector at this point.

For signal wires, cut the +ve wire of two of the ESCs and then attach them to the rx.

No problems at all. It is called a 'power spider'. I'm using the same config on my HoverBot.

If i am not wrong you are making something like, two DFs will produce thrust for vertical lift and one DF for forward flight. This is a tough job bro.

@Swapnil
Is it power distribution cable(wiring harness) we use in multis?

Note one thing though, you'll need good quality and appropriate gauge 'silicone wires'. Also the max battery current sholud be a bit more than the total maximum current drawn by all the EDFs.

Here's how I did it. (see pic)

I guess you'll need to solder it as it gives better results.

Just out of curiosity, how are you going to do the channel mixing and mapping?
Like Dharmik said, it's going to be tough. Not just weight and C.G issues but sheer circuit complexity.

Keep going bro! Good Luck!
