So I've done search upon search and it seems like this might be something I can't accomplish. I'm looking to use one of the 2.4ghz hack modules (preferably one of the OrangeRX ones) in order to change an older Caliber 3ps into 2.4ghz.

The problem I have is finding the right 3 wires inside the transmitter. Has anyone done this conversion or does anyone know what wire is the PPM wire inside a Caliber 3ps?

I have one of these radios also. I would like to know if you figure out how to do this. Or are you interested in buying my radio?

I have one now and want to figure out how to do it. It's a great radio if I can make it 2.4ghz.

What chip is in it? I have done the FR Sky mod to a couple of old KO radios with some success. The range wasnt all that great but it was enough to race F1 on a 100x50' indoor carpet. Have to use the FrSky receivers but they are cheap. Where is the link to your mod.

I haven't done any mod yet. I'm trying to figure out the wires, there's so many internally that I can't figure it out.

I'll post up some internal pics tomorrow of the radio.

I kinda let mine go with a new baby arriving etc. but I'm still really curious because I'd convert my 3ps and sell my spektrum.

well i need to find the ppm signal to see if this will work
but I did find a way to upgrade the M8 and I will now have to try it on the 3PS
check out my 2.4 conversion for M8

I'm attempting to replace the lithium battery in my original (1990's) 3PS Caliber transmitter. I purchased the lithium battery. It is essentially a 2032 disc battery with solder tabs on it for PCB mounting/assembly. Just curious if anyone here has had any experience replacing the lithium battery in their 3PS transmitter?

What I'm looking for is specific directions/instructions in regards to which section of the transmitter the battery is contained. Location of battery. I did'nt necessarily want to disassemble the whole transmitter.

I'm surprised this info is not provided in the user manual- it just says after 5 years the transmitter would need to be serviced at a certified Airtronics repair station. I sent an inquiry to Airtronics technical support, I get no reponse?

I posted a few images of a disassembled transmitter rear cover (from another poster) as a guide.

I'm an experienced solderer.

Appreciate any input........

Any updates on switching the radio to 2.4 or replacing the internal lithium battery?

WestCoastD

yes, I'm still curious if there are any Airtronics Caliber (CS3P) users out there?

I dont think its possible. Module made to convert 2.4ghz, in the early days of Spektrum. They were made to convert the M8 radio. Spektrum discontiued the module Years back. You can search but you'll find discontinued. Vintage radio. You may find under Spektrum for Futaba! Good luck!
