Rc8e Gearing

[Ozric]

Hi all
New here and new to brushless. I am in the final stages of finishing my Rc8e conversion. Just waiting for lipo's and a couple of pinions.
What I would like to know is what gearing to go with, I have recently aquired an MMM combo which is the 2200kv motor. As I understand this is more of a truck and truggy motor than the 2650kv. But I am hoping it will still be fine in the buggy.
The track I run at has 3 long straights and some tight infield turns. The nitro's really get going on these straights and I am looking to gear my rc8 at 20/46.
I would like to know if this is likely to cause any thermal issues?
I will be running on 4s 4500mah 30c packs.
Any help and advice would be appreciated not race any electric until now.
Cheers
