Default nEED HELP ON rADIO/CONTROLLER

Hi..need some help on Radio/controller.

1)When buy 2nd hand radio which does not have receiver..does it means that I have to buy the crystal also?

2)When buy new receiver..will it come together with crystal?

3) If I bought a car equipped with receiver but without radio , do I need to buy the radio only or also the crystal?

4) Crystal determines the frequency?

5) If i have 3 cars with 3 different receiver (one receiver attached for each car), can I use the same radio (i have only one radio) with 3 different crystal interchangebly?... I mean..after i finished playing with my 1st car..can I then change the crystal..and play the 2nd car..and so on..?..

For question no. 5, if the receiver is 3 different receiver(different brand/model)..then how?

There is one slot at my radio which shows the frequency. Can I take it out and put another crystal?

3) If the radio have crystal but no receiver (2nd hand)..can I just buy any brand/model receiver?

For Q5 - cannot......maybe this can cause run away. Not recommaded

Crystal cannot go to radio as you like as it got stated Tx or Rx. As I know not recommaded to mix brand on radio and crystal

No, you must buy compatible rx, which mean matched Tx and Rx

Recommaded, buy set of radio and buy 2 more rx which same as model as the radio set. Best buy 3 radio...easy

Azmin,
If it's an AM radio, it should work between brands, BUT sometimes different brands assign different channels differently, so if you plug in the servo to channel 1 and throttle to channel 2, you might end up with your trigger controlling steering and your steering wheel controlling the ESC. Haha. Not sure if you can just plug steering into channel 2 and throttle into channel 1 to rectify the problem. It worked for me before (mine was a futaba receiver, the TX was a Smartech) but I cannot say if it works for all receivers. Also, you might end up with the servo direction reversed. This should not be a problem for steering if your TX has the reverse direction switch.

If it's an FM radio: theoretically Sanwa and KO works with one another and then Futaba, Hitec and I think JR works with one another. But you might still end up with range problems, and also the above headaches I mentioned for AM radios. Some receivers, like the LRP ones seem to work with any brand radio.

The best is to get same brand tx, rx and crystals. If that's not feasible, try and test before buying (you'll need to bring your tx, a pair of crystals, a battery pack, an ESC and motor, and maybe a spare servo. On second thoughts, just bring your whole car. haha).

Bro,

I have 2 radio, Sanwa and Futaba, both AM.
I'd try to mix the tx and rx...its works.
I think we can mix a brand for tx and rx but need to make sure its freq range is same....AM tx with AM rx and vice versa. (Same crystal freq. as well).
Just need to try first as our friend said...bring all your items and try before purchase....

MX3 will do the job already. Cheap somemore. If you get highend radio then the rx will be expensive too........
