I found the 4PX still listed on Futaba's website but all retailers show it as being discontinued. With all the upheaval in Futaba distribution due to the Hobbico bankruptcy, it is hard to get any real information. My guess is it is going away in favor of the 7PX. There is not much difference in price but I like the 4PX a little more. I was drawn to the 4PV at first, but it and the lower models don't do FASST.

Now that I have looked at the higher end models the lower models are not quite as appealing. Even though I know it is big $ for features I don't need right now.

I picked the wrong time to start looking at trying a new brand of TX.
