HITEC PRICE
The HITEC sells for about 90 online. Its Digitial has awesome power and plan and simple works without failure. Servos are almost a pay for what you get kind of thing I'm sure less troque will get it done but they will fail and if I can get 2 for 1 and just make the intially purchase seems like less of a hassle.
If you plan to race back any steering servo you own with a HS645. It will get you through in the event any servo goes bad and at 30.00 if you do burn it up atleast you can still get from Qual's into your mains.
