I did the same thing about 4 months ago, going from a dx3r to the Lynx 4s. Glad I did. programming takes bit to get used too, but it so much smoother and faster than the spektrum.STeering is instantaneous.Unless you need telemetry, use the axiom 2 receivers as they are fastest. And cost of new receivers? 33 bucks! lmao IMO this about the most overlooked weapon out there.
