Default RE: whats the difference from regular and digital servos

Digital servos offer a tigher deadband and higher refresh rate (300 times per second vs 30) thus producing greater holding torque. Power consumption is about 15 -20% greater in most cases.

Pilots of average to above average skill will be able to tell the difference when flying high performance planes.

I don't agree with the analogy that they are 3-5 times more expensive unless you compare them to basic standard servos that would not be recommended in most applications where you would use a digital servo anyway. For example... the Hitec 645MG typically sells for about $40 where the digital version 5645MG sells for $55. That's roughly 40%, not 300% -500% more. These are good servos for most sport application, where a higher caliber pilot flying a high end model should opt for a coreless motor product like the 5945MG or at the highest level, the Titanium geared 5955TG that put's out 333in/oz of torque. Granted these servos do cost more, but are worth the extra money due to thier durability when stressed to the limits.
