hi everyone im from dellhi . i want to buy a new or used tx and rx for a car,i only want to buy 2 stick radio as i dont like those trex modles ,i m confused as i want a radio which can work for atleast 1 km , can any body suggest me which radio and reciecver will be best fo me under budget of 6000 to 8000.

What do you mean by this?

try this:- http://www.rcindia.org/for-sale/sale-of-tx-rx-and-crystals(72-mhz)/

you can have this as it is available with me till now and last price will be Rs.4300 + shipping


good deal!!

i mean iwant to buy a new or used rx and tx . but it should have a range of at least 1 km.

the range is 1104 meters specifically

Well if u would like to go a little high on ur budget i can offer u a Futaba 6 EX set which will be a long life investment for u in as good as brand new condition

1) Futaba 6EX-PCM (Box Packed only used for 10 Flights Scratchless as good as Brand New Condition)
    Inclusions:
    1. Futaba 6EX Tx 72.410 Mhz 
    2. Futaba R168DF Rx 72.410 Mhz Dual Conversion
    3. Rx Batt original 1000 Mah 4.8VDC
    4. Tx Batt original 600 Mah 9.6 VDC

Asking price 12000 INR + Shipping at actuals (Shipping at Buyer's risk)

this is better option as it is new and also has 4 servos with it at the rate of 11400rs new by mr. Sai
hitec optic 6 combo

one thing can u tell me i m looking for a tx and rx because i want to build a car .
i already have a rx and a tx 27mhz. but the range is to low as they only workin 200mtr. i want an rx and tx of atleast 1 km range . spectrum rx6110 and dx6i tx has this power but in india
they are about 16000 rs and in us ebay it is only 160$ or 8000rs apprx . so can u suggest me if buy this from us ebay or go for any other model in india which has same power,.i dont know about any model, there is no place in delhi to purchase.i m intrested in this spectrum model. help any one

Have you considered this ? http://www.rcdhamaka.com/index.php?main_page=product_info&cPath=89&products_id=226

The RCDhamaka folks can help confirm the average range.

BTW, at 1km you cannot see the car Are you doing some kind of FPV ? 

Ordering radios from outside pretty much always ends up in customs hassles.  Based on the history posted here by various members, it can be done, but it may test your patience. 

Since you seem to be going for an aircraft radio for car use, almost any full range airplane radio should have this range (so you are not limited to Spektrum alone).

thanks prateek ,
can u tell me few more things

#is there any range difference between using various frequencies like 27mhz,42mhz,72mhz  and  ,2.4ghz (new one).difference concerning controlling upto 100mtr ,200mtr ,1km.if yes then which is the best,

#i searched and found on ebay (as i dont knoe any other site to purchase rc radios)that spectrum dx6i and rx 6110suitr under my budget as itis only for 160$ or  7360rs approx.+ shipping i dont know how much as these us persons only send bu usps with insurance.so should i purchase it frm ebay. or should i have to pay any additonal cost
like customs and all ;.

Range is dependent mostly on TX power and capability of receivers, than what frequency band is used.

There are many threads here on importing radios, and the associated customs issues. Please use the "Search" option from the menu.  Simply put, it is best avoided in the current climate.  You can expect to pay customs costs up to 25%.

thnks anwar
concerning patience i have much for a good satisfactory product butmain thing is money. i dont want to spend over 9000.
that means the higher i go in frequency the higher range i will get . actually i m using wireless camera on car thats why i want higher range

I am not sure how you arrived at this conclusion, but it is not generally the case.  In fact, for normal RC applications, both the FM bands (72Mhz etc) and 2.4Ghz will yield similar ranges (as long as you use the "full range" units of both).  Plus "range" itself is needs some clarification, because pure "distance" achieved cannot be considered as "range", it is also a matter of "how clean the signal is at a particular distance".

People have reported higher range here, with regular 72Mhz radios and Corona receivers.  Unless you want a Spektrum radio for long term usage, you have lots of options locally itself.

Sir,
72Mhz or 2.4Ghz is just the carrier. It is the spectrum used for communication. It does not have to do with range. Range depends on the output power of your transmitter - TX. Futaba 2.4 Ghz transmit a power of approx 170 mA. A typical 500mA power output would give you a range of approx 1 mile or more.

Range is also dependent on obstruction. Since 2.4Ghz waves are smaller, they tend to get absorbed easily and hence they say the range is less. With clear LOS, a tx transmitting at a power of 500mA would give you 1 mile on both 72 Mhz and 2.4Ghz.

People are moving to 2.4Ghz not because the range is better, only because the interference can be avoided and no clashes beacuse of continous hopping or time slicing.

However, 72Mhz would be less prone to obstruction AS COMPARED to 2.4Ghz because of the wavelength size.

Hope this helps.

Cheers!!!

thankyou
saurab and anwar

as i must say i got all download from saurab easily while anwar points were quite techinal to me as i m bignr , but thank u so much to both of u. :

can i get  a programable rx and tx with 500ma in 10k

what is fpv?

shrivastav sir i have just checked

http://www.gpdealera.com/cgi-bin/wgainf100p.pgm?I=FUTK63**

there is nothing like 150 ma or 500 ma in features of tx

Ummm I think all these radios are meant for planes... Car radios are 2 channel... You won't need the other 4 channels...

Please check your Futaba manual. The power will be mentioned in the manual. I have seen it in 6EX radio manual.

I dont think you will get a radio with 500 mA power output. Can you be a little more specific what exactly are you looking for?

Are you looking for a transmitter and receiver for RC flying or looking to JUST TRANSMIT VIDEO signals upto 1 km?

oh comon , i need minimum 4 channels

actually i m building a robot car in which i need 1 rx and tx of atleast 5 channel and atleast 800 to 1 km range .and after that i will transmit video signals from than vehical to, just like a bomb defuse robot car .

ok. in that case, you may want to get the Hitec radio from Sai (11k combo) and also get an FPV with atleast 1Watt output. you can get all of them from Sai.
