Despite the numerous similarities, digital servos provide many benefits over traditional analog servos. This article will discuss some of the advantages of choosing digital servos for your next R/C project and address the relatively few drawbacks. A future article will describe the technical differences between the two.

The primary benefits of a digital servo relative to an analog servo are:

1. Improved holding torque
2. Finer resolution
3. Smaller deadband
4. Faster acceleration
5. Programmable functionality

There are three primary types of commercially available plywood common to R/C airplane construction, each with its own benefits and drawbacks. Those three are: aircraft grade birch, interior grade birch, and poplar plywood better known as "lite" plywood.
