while this is kinda irrelevant, when you watch discovery wings and they show those 4 engined pusher planes that look like a paper airplane and they show the controller, it is ALWAYS a futaba 8u. i watch that channel all the time. i was watching history channel about an hour ago and it showed a commercial for that new show tactical to practical. it said "hunder ellis is getting a try at remote controlled airplanes" or something of the like. then it showed the controller. it was, you guessed it a futaba 8u. that is because it is not incredibly expensive, and has all kinds of wacky features on it. i have currently a 4 rotored prodject going (it looks a bit like the draganfly but it looks like crap because i made it myself ) that has some fancy requirements. when the throttle stick is moved, all four motors come on and spool up at the same time. when the aileron stick is applied, it has to add on one side and subtract from the other the throttle setting to make it pitch. same with elevator. that took 7 pmixers. also, because you have switch assignability, you can make it null on the switch, so you don't have to flip anything. guess what radio i have. the futaba 8u. it is really a versitile thing. you can buy one used for the price of a new 6x with a flight pack. if i were you and wanted to get into gas, save up that much longer and spend the extra money because if you ever get anything more complicated than a trainer and you have a standard 4 channel radio(not harder to fly mind you, COMPLICATED) you will either have to spend all kinds of money on on-board stuff that you have to land and take off the wing to adjust by guessing and trying again, or spend more money on a new tx. it is easier to get what will last you longer for more than to keep buying what you need in the meantime for less.
