RE: What radio to get
As far as I know, all current production transmitters have servo reversing. Best is highly subjective. Any of these brands, if they have a 6 channel surface radio, should be great.
Airtronics
Futaba
Hitec
JR
JR Sport - less features and lower price than regular JR but same quality
Polk Hobbies
Tower - which I have heard is relabeled Futaba
