I fly on the TARANIS 9XE I also have spectrum dx18 and flown futaba for many years. as an aerobatic pilot. I love the 9xe it allows me to do anything I can conceive off plus you can update the firmware on the rx very easily. I am currently flying a large Lysander with a saito 450 radial and its flown quite happierly on the 8 channel x range of rx , it must be said that having the self test function buit into the set and a constant signal strength during flight gives e lots more confidence than other radios I have owned plus they are cheap.
The only thing I would ad is correctty placing your antenna is very important with frsky especially if you have a huge radial in front of it
