These are what I use:

These servos have amazing speed and torque. The alloy case and titanium gears make it very solid too. Awesome servo for the price.
The main downside is HK being in China means service and support will be very difficult, if available at all. You have to decide if the cheaper price is worth it to you. Buyer beware I guess. Some people don't like HK stuff and that's fine, but personally I have been very satisfied and never had any issues with these servos.
I've used HK for some other stuff before and have not had any issues with the products (though I sometimes prefer to use hobbypartz because of the free shipping if they have a comparable product).
Regarding your comments... how much does torque effect a larger scale model in a servo? Meaning, the higher the torque, I assume the better your turns will be under higher speeds / conditions?
Also, what does it mean to run at 7.4V? How do you do that? I assume that coming directly from a RX it will always be 6V? I guess I'm a little confused there... or does it mean you would have to externally power the the RX with a RX lipo or battery?
