Through shocks i meant sparks(sry couldn't find the crrct word)
So, now what do you suggest me. please give me suggestions that are less costly(cause i hav already put in a lot of money in the electronics.)

I don;t know if there are cheap solutions available if you have fried your electronics. Any way, if you have manual to your Rx, then see what is the process of initial binding to the Tx. Remove the ESC, get hold of 3 pencil batteries and connect them in series to get 4.5V and then see if you can connect to your Rx and try and see if there is a response from the Rx.

i tried this but still there is no response from both my receivers. whenever i connect a servo to my Rx and then connect the battery there is a slight movement(only for a fraction of second). then when i take the battery out there is again a movement but in between it does not receive any type of signal.

Slight Movement? Can you elaborate? If it is the servos that you are talking about, then yes, that means that the servos are getting voltage. First try to bind the Rx/Tx as per the manual supplied with a different power source to the Rx. Then first you switch on your Tx, and then connect your Rx, without the ESC (direct connection), see if the servos respond to the signal from Tx.

QuoteFirst try to bind the Rx/Tx as per the manual supplied with a different power source to the Rx.

He says it is a 35 MHz set. The question of "binding" does not arise.

Hi ,
I think your issue is  as  follows :

Your issue is your Radio , I dont know if Graupner is Positive  or negative shift , but from my experience Saju uses a Graupner  Radio with a Turborix receiver  which works very well with a Futaba , hence  assuming then that  Graupner is the same shift system as Futaba then the GWS JR Type might not work with this Tx  so the best would be to try the  receiver from the futaba type  and see if it works .

Or the other option is to buy  a carona synthezised  which works well with  any type of shift.

And If you have reversed the + and negative between the  battery and ESC you have either spoiled the ESC or the battery by now.

QuoteAnd If you have reversed the + and negative between the  battery and ESC you have either spoiled the ESC or the battery by now.

As I had said earlier, the ESC would be fried for certain. But it's entirely possible - and even likely - that BOTH are lost for good.

BTW how does one "reverse" connection on a Deans?  :headscratch:Presumably desoldered and re-connected? Rather ambitious for a total newbie!

True... this has the symptoms of a TX not talking to the RX.  However, in the few sites where the X-306 TX is listed, it is listed as Graupner/JR, so it is more likely a JR standard TX. Since the GWS receiver is also confirmed to the JR compatible, it would be prudent to confirm that the channels also match between the TX and RX. Turborix has receivers that are shift agnostic, just like Corona.

So do the 3 fraction digits in 35.xxx on the crystals on both match with each other ?

Why not seek the nearest R/C flyer and have an eyeball with them. Carry your stuff and see if they allow you to mix match your Batt/ESC/Motor with theirs and zero down the issue.

Even I had a nightmare at 3 AM when I connected ESC/Motor/Batt together for the first time in my life as the motor(actually ESC)  kept on beeping.  The problem was I connected the ESC to wrong channel on Receiver (Futaba 6004 micro).

All the best !

True Anwar , the other possible issue could be unmatched crystal pair like one single and the other  dual conversion .

Surely a Tx rx   communication problem  nothing else .

A "Servo Tester" comes really handy at these times, and while constructing a scratch build plane. I am making it DIY (more trouble than just getting a ready made, but thats lots of fun!!)

Not to be misunderstood in any way but both these were covered in my post:

QuoteJR 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.

Possibly one is not really following the thread in continuity.

thanx all for your replies. now i am looking forward to buy a new receiver (as recommended) of futaba but don't know where to buy a 35MHZ futaba reciever from.
Can anyone help me?

rgrds,

Sumit ,
The best is to buy a synthesized  receiver  as it will work with any type of radio.

If you read the thread carefully, you will realize that your transmitter is deemed more of the JR standard, so buying a Futaba receiver will not help.  As Sai suggested, please get a synthesized shift-agnostic receiver like Corona as it handles this ambiguity, and that saves you the trouble of hunting down the right crystal also.

Also, when you seek help on such issues, please try to respond to specific questions raised.  For example, it was asked multiple times whether your channel (the "xxx" in 35.xxx) of the crystals in both the TX and RX match, but it went unanswered.  This makes such "remote" troubleshooting even more hard  

Answering the pointed questions really helps clarify the situation 

Quotebut from my experience Saju uses a Graupner  Radio with a Turborix receiver  which works very well with a Futaba , hence  assuming then that  Graupner is the same shift system as Futaba

Anwar, this indicates Futaba compatibility and not JR. Anyway, a shift agnostic Rx, as suggested, is the best option.

Please see my response below, which I am quoting from my earlier post. Actually this looks like it is JR, and you can pretty much confirm that from Google searches.

Point taken. I just went by Sai's reference.

So as you said anwar that i should use corona, u only suggest me the place from where to buy it. 

That puts me in the difficult position of visiting the website of every LHS that has a website   

I have a feeling you already know the usual suspects !

BTW, I still do not see if you have established that your receiver is the problem, or just a crystal issue.  Hunting down a crystal can also get just as adventurous, so I guess there is no harm in getting an "extra" receiver !

Is there no way you can visit a neighboring flyer who can verify the setup for you ?

the only place i know is rotor.co.in, they deal in all odd/All frequencies (which is a good thing)! i also remember seeing some guy from Indiarc/Rcindia posting a sale Ad. on 35Mhz stuff !

PS: http://rotor.co.in/product-find-action.asp?pdt_name=35mhz&code=&x=0&y=0

sahil

I thought RCForAll and IndianHobbies also had them (did not verify). I mean the Corona ones.

well for one i was referring to the choice of receiver brands available at rotor and yes i think sai also stocks 35mhz stuff but i don't know about Indian-hobbies all i haven seen lately are 2.4Ghz stuff !

Sumit,
If I were you, I would go by Ujjwaana's suggestion of trying to find a more experienced (than yourself) flyer in or near your area and then take all your stuff to work out how things are supposed to work. You have spent, by your own admission, quite a sum already and have not got the connection proper. So are you willing to keep on experimenting more at your expense or would prefer to seek guidance? Bythe look of it, you may have fried more than one item, so just be careful from now on.

Regards
Pankaj

yeah thanx for reminding. I will be visiting shrikant may be he will help me out
