I set up my esky D700 and I am using the TTX650 the menus are pretty easy to setup. I have used the ttx650 for airplanes and helis though the eskyD700 was my first 450FBL heli.the rx work good as well I have used the 624 rxs on planes and currently on the esky heli the range is good. I have flown some planes nearly out of sight and still have signal. they also make a 625rx with two longer antenna the 624 kinda has a short antenna but no problems
