i didn't have to give jewerlys for my 6xas.
i just had to write alphabets

i also have a radiant 6 and a JRmaxx
other than not being compatiable with futaba
different charging jacks,connectors, servo size,servo arm

trying to keep everything 1 brand...i choose futaba

hitec is compatiable, but the servo arms are not the same size
found out the hard way...lost some wing nuts.

tower hobbie's are futaba

i run off the 6xas and purchase the skysport4 system instead of a flight pack.
it's about the price, but i'll have spare TX battery packs i can use for 6xas
