Hi Yub, yub, cmdr!,

The 6EXA is PPM, it is not available in PCM.

Range of a transmitter is one of the hardest questions to answer, as they will vary so much from make to make and even from one 6EXA to another 6EXA. Variables play a large factor in the range of a radio also, from your geographical location to whether you are in an urban or a rural area. The closest that we can come is that this will fly your plane "as far as the eye can see". When you get your radio, we would recommend that you do a few range checks yourself with it, take the average range and this is the "range" for your transmitter.

If you are using the transmitter and receiver packs that came with the system, and they are not upgraded as far as milliamps, you should be able to fly safely for 25 to 30 minutes, but again, this is going to depend on how many and what type of servos you are using, what type of ailerons, rudder, etc, your plane has, and the winds will even play a big effect on battery life.

I hope you find this information helpful. You can also reach our Futaba support technical team at 217-398-8970, or via fax at 217-398-7721.
