should this effect my controls. my remote is 75.57mhz and my crystal on my reciever is 75.46 mhz should my heli still work. it wont initiate

smokingcrater

let me get this straight, they are on different frequencies and you are wondering why they won't work??? besides, it is illegal to use 75mhz on a aircraft anyway...

Aerohawk

Illegal!!!! Who is gonna find out????!!!

I live in Australia and I am using American 72mhz frequencies! We are suppose to be using 35mhz here!

Both the transmitter and receiver frequencies must be identical!! Otherwise it will not work!

I'm using 72mhz because I buy all my heli products from the USA and its just easier this way!

ahh yes, but the poster was from florida...

who is going to find out... well for starters when the heli goes out of control, kills someone, and the owner is sued into oblivion (or possibly jailed) for negligent homicide for knowingly endangering someone by running on ground frequencies.

if your radio and rx on both on 75, you need to find a new tx and rx. you can't change crystals to change bands.

Aerohawk

Yeah I understand what your saying.

We all take a risk when we fly our helis (or planes).

However, we never know when interference will occur, even though we are using air frequencies. It can happen anytime. And helis are the most difficult aircraft to control with glitching!!

You never know if somebody nearby is using the same frequency as yourself!

So you yanks work off 72mhz for air and 75 for ground.

Us ozzies work of 35mhz FM for air and mostly 27mhz AM for ground.

if i had to go to jail it would be juvy im only 13 straight a's so i dont think thats going to happen.the reciever is a gws reciver

Aerohawk;

We also use 27mhz, but it is most commonly used for vehicles and boats. It is also sometimes called a shared frequency, because aircraft are allowed to use it, though mostly only what we would call "Toy quality" planes ever use 27 band.

72 band is the standard for the average r/c pilot and 75mhz is supposed to be restricted to land use only.


heli;

Double check to see if the crystals and the radio band matches. You cannot use 75 band crystals in a radio system designed for 72 band.

BTW, I have never heard of a 75mhz GWS radio system. Has anybody else?

NYHOB

Both crystals must in same frequency

heli;

Ok since we figured out the 75mhz problem, lets move on from there.

1) Normally crystal tags are marked with the same frequency on BOTH the TX and RX crystals. So all for intent and purposes, they SHOULD match.

2) If the tags are removed, the crystals themselves MAY have different numbers, but as long as they are a matched pair from the same manufacturer, you shouldn't be having any problems.

3) The Transmitter (TX) and Receiver (RX) each must use their designated crystals. TX crystals will normally have a "T" somewhere on the tag and RX crystals an "R". They cannot be interchanged.

4) The TX and RX MUST be on the same band. You cannot use a RX designed for 27mhz with a TX on 72mhz, by installing a 72mhz crystal in the RX or the reverse.

Lastly, a complete description of your equipment may help us determine a cause of action.
