When I try and connect them the reciever is blinking red. Any sugestions as to what is going on?

I assume you mean r603gf?

They're not compatible. That's a FAAST rcvr and the 4PL requires a Futaba FHSS type rcvr like a r2104gf.


These use diff encoding/decoding and they will not work together.

So... Will the R603GF work with 3PK Fasst?

Yes, that rcvr is made for the Fasst systems...

Why, when it says FHSS on the receiver?

That's what Futaba says....


Not all FHSS is the same, not even within same brand.

Took it back to the LHS and they got it to work fine!?!?

So what were you doing that was wrong enough you couldn't make it work?
