Its great technology no doubt, I have one...but if you plan on having several planes it is cost prohibitive at this time, once rx's are half price,,then it may be worth it,,when one rx is the cost of a flight box(servos/battery/rx/xtal) its too much...my main problem is different, right after I bought it I bought another 6EX from a bud and had to send it to Tower to change the xtal from 39 to 40..fee says its $40.and s&h..ended up costing me $90 (fee plus labor) well they got an earfull and wont ever see my radio business again..course I have like 5 of them, a friend just got a 7C and said " I think this thing gets cable"...still wish I hadnt gotten the 2.4...Rog
