Digital Recievers and ESC's + Servo

[Bharper]

Seams to me digital has great and (what I did not expect) drawbacks. I bought the Flysky FS GT3B 2.4GHz 3-channel transmitter, FS GR3C 2.4GHz 3-channel receiver. I have not gotten her in the mail yet, and already went shopping for a digital high/fast touque servo for my old 1/10th scale truck, with the thinking I can use this servo latter on advanced projects. Before I know it, I got a $50 servo, and have not even plugged it in to the above receiver, when it dawn on me that this servo might need a programmer purchase at some future point. I know I could have shopped around for a cheaper servo that did not need ever a programer, I ended up getting the Hitec HS-5625MG with only 3 metal gears installed, and it's programmable, and yes I think I paid a stupid price of $46.99 U.S. Once I started reading the specs, what is this self calibration (what I did not expect about digital) is thing going to "home itself" every time it gets power. What is this coreless design, but a zapping the hell out of my batter so be so quick, I mean could I have gotten another "digital" servo that just worked like the old analog ones?

I am hoping that you guys could recommend, a servo 1. Last a long time. 2. Work like the analog ones I am used to. 3. Be fast, without compromising the current that I was used to seeing, that uses PWM like digital receivers put out.

What servo should I have gone with? I mean, this is middle ground $ for digital, and I wanted something for future adventures in mind. Should I buy all metal upgrade gears like x2 sets, like now, and when I go to sell it in the future, I get a lot, for having x2 unused sets?

Will my IntelliSpeed 12T Modified Electronic Speed Control with ABS Brakes & Reverse also not work with the above receiver?

I've used digital servos for ages without any programming box

I have yet to understand what a digital programming box adds on top of all the bells and whistles built in most modern radios (out of which most of us only use EPA's and expo anyway)

Don't worry about it
