Where or can you turn the T-FHSS on the 4PM to just FHSS ??? I am wanting to upgrade my 3PL with 3 R2004gf FHSS receivers to a 4PM. i have found a R2004gf receiver description that says it can be used with T-FHSS transmitter, but the mode needs to be changed from T-FHSS to FHSS mode.

I'm away from my son's remote at the moment, but under the receiver menu, you can jog through the modes with the D-pad. I believe this is under the 3rd page of the sub-menu.

*edit* please check pages 30 -31 of the manual.

I was just looking at the 4pm manual and on page 32 there is a description of how to link a non T-FHSS receiver. Instead of using buttons on the tx to link T-FHSS receivers, you push the link button on the receiver.

I can say that the T4PM will not bind with the R2004gf receivers.I found someone who has a T4PM and we tried it a couple different ways, no go. The previous model, 4pm might could have but don't know for sure

the rx ur trying to bind is a fhss not a T fhss

No FHSS but you need S-FHSS

The T4PM and the 4PM are the same thing.
Per the chart The R2004gf is not compatible with the 4PM.
