Can PPM be added to a Futaba T5UAF transmitter

I have a good Futaba T5UAF transmitter and wondered if I could update it to use PPM coding to satify the need called for when using the Corona CF9 2.4GHz modual .

I may be wrong, but I think that is the normal mode of operation for that radio. I'm pretty sure that is what the "F" stands for in the model number.

I'd go with Assan instead, more receiver options from small 4 channels up to 10 channels, starting to rival the selection that Spektrum offers.

Dear VI; You are a little wrong about the F in the UAF ,it means fm but Futaba did make a 5UAP model which has a selectable choice of PPM or PCM codeing . Both used the FP-TP-FM RF module I could 'nt access specs on Assan at the time Regards RL aka Ampmister

FM=PPM from everything I've read even though it is a little deceptive.

Can the Corona module work with fewer than 6 channels?

I took the info from the Futaba instruction manual . It lists under modulation FM-PCM/PPM selectable (T5UAP) , now Iam uncertain which used in the 5UAF model as it's set modulation . regards Ampmister

Hi buzz ; The Corona module comes with a 4 channel receiver which is fine for me . Regards Ampmister,

The Futaba radios use the following as the "default" modulation method:


On the 5uap you can select between the two method, but from what I read in the manual the 5uaf is FM only. What receivers are you currently using with the radio? That would tell you right there whether it is FM/PPM or PCM.

You are right on the button , the receiver is a hitec 555 fm on chan.48 . Why the VI moniker you're anything but . Thank you very much for setting me straight ! Regards Ampmister
