One radio for one receiver?
Lets say that my transmitter is set to frequency 58. I then buy an additional flight pack to be install in another plane with the receiver also set to frequency 58. This way I can fly both planes using the one radio.
I understand that the receiver that came in the flight pack with the radio combo is tuned to match "exactly" the frequency of the radio.
Should not the new receiver be put on an oscillating scope (or something) and adjusted to match exactly the frequency output of the transmitter as well?
If it is not set exact but within an acceptable range, are there any possible problems that could be encountered?
