It appears to be a single conversion model. I see it listed at a bunch of places, but not on the US Futaba site. Bruce is right that the new 6EX transmitters can do PCM. On a trainer it's probably overkill to get a PCM receiver. I'd suggest buying a dual conversion receiver. Futaba has several choices. You might also look for Hitec, they have some dual conversion receivers that work well. Just be sure you buy the version that's compatible with Futaba. I have two of the Electron 6 receivers that I use with my 6EXA, they work great.
