Eletronics set-up for RWD?

Hola!
I was wondering if you guys have any tips for a RWD set-up?
As far as i know a lot of people run savox servos for torque and speed. But they are quite pricey. Any other alternatives or is it worth coughint up the money for it?
Also wondered about Sensorless vs Sensored esc and motor for running RWD? is one or the other better?
Thanks,

I've been running Solar servos for a couple years now on several of my RC cars.

You won't get street cred, but you can't beat the price. For the cost of 1 Savox servo, you could buy and break 4 or 5 Solar units. I run a D770 @6v on my Sakura D4. I have a spare Castle BEC so I may run it @7.4v for the speed boost. No complaints here.
