Yes, you can. I foresee no problem except connectors! You will need 3 sets of 'y' s. Or make your own, if you can find someone competent.

I have also made a Y connector at home using two servo lead extensions.
Here is the pick...

if u want to do thing want to do...heres what u can do
take 4 servo extensions
cut the power  wires of three of them
attach them to ur esc and use 1 which you havent cut on 3rd ch for powering the rx
so u would be giving power to rx with 1 esc  while feeding only the signal in the other the three esc's
this would surely work....
i this way ur esc will be saved too and can later be used for single purpose

Do not do it if more than 1 esc has a bec in it.

If more than 1 of them have a bec in them, cut the middle wire(red) that goes from ESC to the RX of all ESC except one - which will power the RX.

If u are powering the RX with a separate source like a nicd etc, then cut all the middle wires (red) that goes from ESC to RX of all ESCs.

rather than cutting them permanently i would prefer to remove the red pin from the lead and place heat shrink tube or tape them at the ends to avoid any unfortunate shorts...

why should we fiddle with esc wires ....instead we should use servo extension cables and cut them ...so esc remains safe  and can later be used in normal use


Title: Re: help please with esc and motor
Post by: vinay on January 09, 2011, 05:07:29 PM
As sujju says, u can just remove the middle wire. Its easy. Just take a needle and move the small black flap up on the connector and pull the wire out and tape it. No need for extension wire.

If u want to connect it back, just put the wire back and it will easily lock in.

anyone please tell me can i use 11.1v 3s 20c 2200mah battery with 25A esc.


Title: Re: help please with esc and motor
Post by: foamybuilder on January 11, 2011, 06:44:29 PM
Yes you can use. Your battery is capable of delivering up to 44amps. Just make sure you dont draw more than 25amps current, by properly choosing the prop for your motor.

its a edf 64mm five blade..


Title: Re: help please with esc and motor
Post by: foamybuilder on January 11, 2011, 06:55:53 PM
Then checkout in the specs somewhere in google to see how much your setup would draw with full throttle. As its EDF my guess is it will draw more than 30A
