I have two good Prism 7X transmitters with good 600mah nicad packs. I just cycled them and the tested around 630mah. These have been good radios and I never had any problems with them.
Both have modules, one is on channel 40 and the other has the Spectra module for selecting any frequency. I have one manual to go with them. These are easy to convert to 2.4 mhz with the Hitec Optima module. I can sell as a lot or if you only want part of these items make me an offer.
