I'd be looking at the settings in the radio. It seems like you like his settings which is certainly a good thing to know. It's not always that it's faster, but sometimes slower. On my radio, most of my servo speeds are turned down and I used negative expo to remove some of the twitchiness.

All that being said, Amain has a deal on the 4pm radio which is a really good radio at it's price point (Low $200s). Stack a coupon on top and it's a great investment.
