catengineman:
I have a question (sorry to keep asking but if I don't know then it is better to ask those who do)

What is the difference between a single conversation receiver and a dual conversation receiver apart from the obvious
would they be interchangeable? if say they were both 40 MHz had the same number of channels and made by the same company.

ie: Futaba have two receivers on their web, look the same, channels same, numbers same but suffix is F or DF
it just states which type you want. now if the better type will work with my FX18
I know I have to fit an extra if I want to go over to PCM rather than the PPM I use at the moment (I think)

Thick Richard,

Scottie:
The difference between single conversion and dual is in both the transmitter and receiver. It is a difference in the way the signal is encoded and decoded in the RF module.

Single and dual conversion are NOT interghangeable.

Scottie.

I have used both single and dual conversion receivers with my Hitec Lazer 6 transmitter, just use the correct crystals, dual or single conversion in the receiver.

As Gribeauval has stated I also use single and dual conversion receiver with the same transmitter which is as far as I know a single tranny...........

I stand corrected... sorry, that was what I was told by a so-called 'expert'.
