Default RE: Digital servos what is the difference??

Nitro-pilot, you don’t understand digital servos. It's not the speed we are talking about, it is deadband and amplifier slopes. In layman terms, digitals lock onto their commanded position better and fight much harder to stay there. This effect can easily be measured (I measured a bunch of servos a while back for this very thing) and easily felt under certain flying conditions. Some don’t care, that is fine, just say so. That would be much better than spreading false info about equipment.

Deathbunny, limp servos when off, that has nothing to do with being digital. It is often from the coreless or brushless motors being used. Good analog servos will do the same thing. Cheap digitals that use 3 pole motors generally won’t go limp when off.

“I fly my planes to have fun and the less flight time I get out of a charged battery pack by using digital servos, the less fun I can have.” Seriously? That is your argument against using digitals? If you don't like them because they are too expensive, fine. No one is saying you can't have fun with nondigitals. I simply couldn’t understand how you could say they weren't any good except for competition if you have never used them before, i.e. it is not possible for you to have first hand knowledge unless you have used them. As for NATS, my suggestion, ditch those expensive battery hungry 3004’s and get an escapement, now that would really be something.
