Figure out what head speed you are looking for and type in the info. It will tell what pinion you need. That is what I did for my 600.
Trex 700E / Trex 500 ESP - Ikon/ HD 500 - Ikon 2/ Goblin 500 Ikon 2

I believe 11T is the smallest your going to get on the 700E. That motor is way too fast for 12s on the 700E even with an 11T pinion. I would run it on 10s with the stock gearing, power will still be plenty, plus 2 5s 5000mah packs would be a nice light weight setup. If you still want to go 12s I would swap the motor for either the Align 700MX 510kv or the Scorpion 4035 510kv motor.60% of the time, it works every time!
