With our TT class rules we must use a 5.5 hobbywing unsensoered motor and any hobbywing esc.
All racers use a 120 amp speed controller as we have had too many 60 amp thermal and cutout (our track is high grip carpet).
11-13 tooth pinions depending on motor temps.

Here is a youtube clip of some of our recent racing to give you an idea of speed, An average lap here is 20 - 21 seconds.
the last guy in the clip RJ is the one we chase each week - LOL

If you are not racing I'd possibly recommend and 8.5 turn (4000kv) motor as it gives a lot more flexibility in gearing.
Your call as to sensored or not (I prefer sensored) is up to you.

As for speed controller,
A XERUN-120A Sensored http://www.hobbywing.com/english/Art...?ArticleID=447 (this can be used unsensored too) or
EZRUN-SC8 Unsensored ESC http://www.hobbywing.com/english/Art...?ArticleID=471

Fire away if you have further q's

Matt
