hopefully somone can give me a little education on this.
Been out of the hobby for 12 years.....back before digital servos were around.

I fly 1/4 scale 40-100cc sport scale and am considering either Hitec 985MG (analog) or 5985MG(digital)
both have the same specs ie: torque,speed,current draw,weight
so many questions.......
is there any reason to use one over the other?
can I just plug a digital into my receiver? Using Spektrum DX7 radio system
do I need to program the programmable feature on the digital?
I am running 5cell 6 volt receiver packs, is that any cause for concern?

sorry for all the questions. Back in the day we just plugged servos in and flew. MAYBE you bought a big honkin' giant scale servo for your rudder back then
