Default Digital servos

What is all the hype about digtal servos Why do I need them. What is the main difference between a good name brand
and a digital ..
Can I fly a plane that the manufacturer advertisers it should have digital servos without them.


Thanks David

That depends. For something like a trainer or something to just bore holes in the sky, I don't think that digital servos are a necessity. If you're flying aerobatics, or scale, etc., where you need precision, then yes you need them.

The advantage of digital servos is that they're precise, strong, and they stay put. But this also costs energy from your battery. So, you have to decide the trade-off.

What type of airplane are you considering putting them in, or are you just asking a general question???

Just my $.02

David, keep in mind that there was a time when there was no such thing as a digital servo and we all got along very well without them. Well, you can still live without them especially if you don’t need them and most guys don’t need them including me. I don’t use them. All the guys that I know who use them talk about how responsive and accurate they are but yet they have 30 percent or more exponential on a control surface. They aren’t doing anything more than some flying around and a few basic maneuvers. They are charging their batteries a lot though. You can get all the touque you want from an analog servo. Since you have asked, you can live without them. Dan.

The advent of digital servos came mostly from competition events, the Tournament of Champions (TOC) in large was responsible for many of the advancements in regards to airframe design, electronics and power plants that so many take for granted today. If you are an accomplished competition pilot, you will certainly be able to tell the difference between the two servos, if you are flying in circles or just tooling around, anything will do, so spend your money and take your pick, it is really that simple.

Depending on its size and power, the CAP 232 might have been a good candidate for some digital servos... For a 'foamie', no. For a high performance bird with a .91 or better, yes.

And if you do go the Digital route, keep away from the low end ultra-discounted digitals, and the very high end digitals. There are several good digitals for not much more than a regular Servo... You don't have to spend a fortune to get them. But then again, you can save even more $$ by not buying them unless you really need them.

Just another $.02
