I have an olderAirtronics Radiant programable radial that doesn't seem to hold the program. I program it for my Me-163 since it is a delta wing. I come back a day or 2 later and it has reverted back to its original program. Anyone have a manual for this radio thatthey would be willing to share some info.....or better yet help me to program the radio?

I can't be sure but I would guess that this Tx is one of the older ones that required a "keep alive cell" to maintain memory while the Tx is turned off. You can take the back off and look for a coin sized button cell soldered into a circuit board. It probably needs replacing.
I ran into the same situation with a fifteen year old AT Quasar Tx and replacing the button cell returned the Tx to proper operation.

RJ, I kinda thought that could be the problem also and since I dont knowthe circuitry but I would think that if the ani battery is fine, wouldnt that keep the programn alive?

RJConnet

No, the Tx battery (9.6 Volts) is disconnected from all circuitry when the on/off switch is in the off position........RJ

It happened to me once on my Radiant, memory battery needs to be replaced, as simple as that
