Certainly a 6.5 is not the wrong motor for a 4wd buggy, you will find it a little easier to drive than a 5.5, and often easier to drive is faster round the track anyway!
Lower turn motors generally rev higher, create more power, and create a little less torque. Gearing is based on the "feel" of the car on the track (gear down for more punch, gear up for more top end, within reasonable limits), and also to stop the electrics from overheating. Although brushless motors tend to have ample punch with any gearing.
Curious as to why you are choosing a Spektrum DX7 and the Ace servo tough - wouldn't be my first choice for electric buggy racing. DX7 is a flight transmitter, Ace is a fine servo but more intended for nitro.

Thanks for the response.
So is stopping me getting a 4.5 and then using the throttle map in the ESC to limit it to 70% power say? Is that equiv to using a 6.5 in terms of drivability if the torque differences are fairly negligable? Given all the motors are the same price, I'm wondering why not get the fastest?
Well spotted on the Radio, I meant DX3R!
Wasn't sure on servo but M-K-Racing had it in stock and I saw a few people used them in CATs. They no longer have it on their website today though and only have Savox that I've never heard of? +- 15 quid on the servo doesn't bother me, so wanted to get the best in the 40-70 quid bracket. Having said that, the Savox has titanium gears which has to be good?
