You made the right choice buying the 4pl. Great radio and i love the features and feel. The lag is waaaaay noticeable with the flysky once you've used the futaba. The piece of crap flysky made my truggy run away full throttle in the middle of a race. It was garbage after that. I only still have it so the next time my buddies have a firepit, that thing is gonna burn. Not to mention 50% of the flysky's recievers went bad and or glitched.
