Which set up for my MRX-3 conversion...opinions welcome

[magman]

I just purchased a MRX-3 and wanted a sensored set up in it.. Four of my buddies have these in nitro form so I plan to show up one day w/my set up and, well...have some fun. Seeing as the car only weighs 3-4 lbs. now and expected run weight of 5-6 lbs., I was thinking of the following set ups.

1. RX8 w/Tekin 2200kv buggy motor on 4s
2. MMP w/same motor and on 4s

I should not need more than 4s in that light of a car. I was also worried about spikes and excess wear on the esc due the fact that a lot of braking will occur. So I am leaning toward the RX8 esc...thoughts
