servos what to use analog or digital

Hi Guys

What type of servos should I use with a digital 2.4 ghz R/C set I am using using analog servos that work well, so what difference does it make by using digital?

Cheers

Strictly all proportional servos are digital; it's just that some use that particular term to indicate that they have special microcomputers inside them which deal with the incoming commands from the receiver and send signals to the motor much faster than non-digital ones – typically six times as fast. This greatly speeds up response to the movement of the Tx stick and increases the power of the servo, but it does take a lot more current than using a conventional servo. They are also a lot more expensive and, IMHO, of questionable worth unless you're into fast electrics or offshore power boats or you have a very large model with a huge unbalanced rudder. Others will no doubt disagree.
Both types can be used with any current radio irrespective of its frequency, so you can use non-"digital" servos with your 2G4 radio. If you decide to use the digital type then you should allow for the increased current by fitting higher-capacity batteries in the model.

Hi Dave

Thanks for that I will be using analog servos as I do not need fast one,s they will be used for sail control {well mast control}as the spars will be fixed to the masts that turn on my model of Ariel a famous tea clipper of the 1860's

Then go for high torque types with metal gears. That's the kind of load that a digital servo would be useful for, but the gearing of a standard high-torque one will probably serve you better as you don't really want the spars to flick round!

Hutch,i initially fitted 2 digital servos in my MTB they were very unstable ,the servo arms moved back fourth slightly without touching the tx and jurky when in operation ,i replaced them with analogue servos which were perfectly still and smooth in operation ,i have never used digital since .

HI Guys,

Thank you for the advice I will stick with metal gears analog thank you.

I have looked at youtube of square rigger clipper ship model were the change of tack is done very fast, not a good look very toy like.

Chjeers,

I had the same experience with the three I tried. I don't like my radio system to have a life of its own!
