E-revo power plant

So, I've been doing more research and reading and have come across a few items of interest..

I only have a pair of 2S LiPo packs, so if I am going to go brushless, then something that really works well with 4S LiPo makes sense to me..

The Novak HV looks to be designed for 4S exclusively.. and with a 4.5T (5,000kV) motor, on 4S, I should see some good motion.. Novaks Remanufactured 'store' has the HV ESC for 99.99 and the motors are available for $79.99.. I'd think that for $180, that would be a nice combination..

Thoughts?
