A new radio and a stack of receivers is not in the budget. Currently have a few Futaba 3pl's and have a bunch of Corona C4SF-HV receivers that I use with them. Does anyone know if they can bind of a Futaba T4pm radio? I found ine used for a good price, and I'd like to get it. Looking at the receiver compatibility chart in Futaba's site, it seems like the T4pm shares some of the receivers that the Corona covers (unless I'm looking at it wrong). I met up with the seller and could not get them to bind. He was not very knowledgeable on the radio which is the main reason he's selling. Too complicated for him. I did switch it to s-fhss before trying to bind it, but i couldn't get it to work. I don't know if there are other settings that need to be done, or if it simply won't bind because they're not compatible. Any help would be appreciated.

From what I see they are S-FHSS, that mode is supported on the 4PL
