I am building an vertical takeoff and landing model.....i got three rotors two will be on wing fixed upward and one will be aft facing forward due to weight constrint i am using single battery...how to connect three esc and bec for a single battery can any one help me please its urgent.

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.

ok thanks alot for your reply....i am doing an Delta wing and using ducted fans for my model two fans will be on aft wing positions and one will be pusher config...

If i joind like what you have said there will be no problem for esc no???

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.

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

yes dharmik same one wat u r thinking i am doing

dharmik can u post some pics of power distribution cables please i need that connections urgently////

This is not my creation but it shnuld like this

@Swapnil
thanuk you for your post...

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.

I GOT wires waiting for connections ...so ill do it carefully as per that diagram

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!

ya its goin to be tough ......thanku for your help..
