I am looking at buying a Spektrum DX3.0 or DX3s. Both will cost 250 USD including shipping. What would you guys get? The 3.0 has the Z270 and 590 servos but has a lower radio while the 3s has the better radio without servos. In both cases two receivers are provided. I am leaning towards the 3.0S but wouldn't mind hearing some input from you guys.
