Question I want switch out a non-proportional transmitter with a proportional one. How do I know what the frequency is of the old transmitter so I can buy the appropriate freq.
It is not labelled what is. Can I buy a tool to measure frequency?
Answer Hi David,
You cannot just switch out the transmitter. You'll need a whole new system including receiver and servos, so knowing the frequency will not really help you. You can find inexpensive and light proportional systems at place like http://www.bphobbies.com
The crystal in the transmitter will give you a clue as the frequency range, but that's all. Just a clue. I would suggest that you search online for your specific system. It should give you the frequency or the frequency range that it is in. Most "toy" R/C equipment is either on 900MHz or 27MHz, but I can't tell you the specific frequency without knowing what it is that you might have.
