You need elaborate on the problem as what exactly are you facing when you say no response does that mean that you hear initial beeps from the motor after connecting to the battery and then when you try to increase throttle there is no response from the motor or otherwise?

Also some times you need to program your ESC to make it work, look for a owners manual on the internet for your ESC and program it and see if it resolves the issue. Thats my 2 cents on it.

Thanx for your response hellflyer and also to point ate elaboration.

I have a 35MHZ reciever and a 20A ESC for 1400Kv motor. I am using a 7.4v 2s LI-po cell.
when the battery is connected there is no responce from the ESC such as beeps. Even when i connect my servo's with the reciever, with my radio off, there is no movement in the servo's(as it catches outer signals) so even if my radio is on, the reciever does not collect any signal. so waht should i do now.

Please specify the brands of your radio equipment (TX and RX).

Also, I have another suggestion/request of everyone. Please always use a meaningful topic name, like "no response from ESC when battery is connected", instead very generic ones like "help me" or "help needed" or "I have a problem".

i have a graupner Tx and GWS Rx.

Sorry for not being more specific about my question.

1) Can you also quote the model numbers of both the TX and the RX.

2) Did you buy the TX and RX from one place, together ?  Are you sure the crystals match with each other ?

3) If you have a servo, and you connect to one of the first 4 channels in the receiver (except throttle, which should already be connected to ESC), does it respond to any stick movement ? (You should try moving both sticks in all orientations, and see if you can get movement on the servo). 

4) Connections that are reversed on the receiver end would exhibit similar behavior, like this : http://www.rcindia.org/electric-power/help-dead-power-set-up-on-mr-moss/ .

Please do not put a prop on the motor while you are experimenting !

my Tx graupner model is X-306 35MHZ FM
my Rx is JR Compatible GWS 6 Channel FM Receiver 35 MHZ

These two equipments were bought from two different places.  Grin
since my Rx and ESC are new i tested my Rx with only connecting the ESC with it and attaching the battery to the ESC(With my Tx switched on), see the circuit shown at the top. in my first try the ESC gave some beeps when the throttle was moved up but suddenly the setup stopped giving response and now when i connect the battery to the Rx also there is no response from the ESC(such as beeps).

all my stuff mentioned above is new except the battery (hope this helps)  Roll Eyes

First try the following....

Disconnect all servos from the Rx and also disconnect the motor from the ESC and isolate/insulate the ESC's motor connectors. Then connect the ESC to the Battery/power pin (not the throttle) and connect the ESC to the battery . Does it make a noise? If not reverse the plug in the Rx and see if it makes a noise or any light blinking on the Rx.

Report the findings.

First figure out if the ESC and/or Rx is dead. If you have access to a multimeter, check the output voltage of BEC (i.e. the connector that goes into the Rx). If it is giving <= 6V then the BEC is OK and the problem could by your Rx in which case you need access to another Rx.

JR radios have a sync signal that is opposite in polarity to Futaba. Very likely that the Graupner Tx is a badged Futaba. This would explain the incompatibilty.

Also check if:
1. The frequencies of the xtals match
2. That they are both of the dual or single "conversion" type. A single conversion xtal will not work with a dual conversion set up, and vice versa.

Do you mean reversing the battery leads to the ESC? If so, you are in BIG trouble and have most likely fried your ESC ! Cry

Examine the xtals. They are marked.

This is strange. I did not know a 7.4V battery could give shocks. I have seen some sparking when I connect the battery to the ESC, but that's OK. However, do not EVER reverse the connection between the ESC and the battery.
