The 3001 Pro has a faster response resolution but I don't really know that you need it anyway, the steering on these is amazing.

    Range is further than you would be able to drive it and know which direction it's facing
    Sound good to me

    Because i noticed that with my merbe..when i would hit the throttle at like 5% there was some slight cogging..and idk if that was the brushless system..or the tx/rx..any ideas? because i put the "speed pinion" in so i doubt that it is the gearing..and im only running the 3s parallel setup..(only!! haha)

    That's normal with sensorless brushless systems, it's not a radio issue. Just try to avoid that throttle range because it's pretty hard on your motor and ESC to operate with that cogging.
    Traxxas racing!

    Could this limit the radio range or cause interference problems?
    Back on topic, the spektrum 3300T has a real short wire that barely reached the antenna mount. Range tested it on a long stretch of street. Failsafe kept kicking after about 150-200ft. Had to drill a hole next to the antenna mount so I can get the wire vertical as much as possible. Went back to the same street, no glitching, the car kept running til I can barely see it.

    My DX7 with a AR7000 receiver is good to 3 miles. This isn't 802.11 with a range of 300feet. Though, coincidentally, I got going 802.11b going 12 miles with two beercans

    Airplane RX/TX are a totally different story for several reasons. One major reason is the fact that your airplane is up in the air and there is very clear, empty air between you and the airplane. And the other major reason is the fact that your AR7000 RX is actually two receivers in one. That makes for much better reception from the TX.
