Great advice as always Ed.
I especially appreciate there is no "best". That is very true. I get a kick out of the guys that just argue and argue that point.
All of the modern 2.4 GHz systems are very solid - even most of the cheaper imports.
I have used all of the major brands and now use Hitec, Futaba and Spektrum. All work very well and are far more reliable than their 72MHz counterparts.
I generally recommend Spektrum due to the many BNF systems especially the wonderful UM stuff.
Life is really good in the radio businss for us the pilots. They are reliable and affordable.
