Servos are found on all kinds of Radio Controlled Models. RC Touring Cars, Buggys, Trucks, Truggys, Monster Trucks, Rock Crawlers, Airplanes, Helicopters, Boats and Ships for Steering, Throttle Control, Rudder Operation and Wing Flaps.
For complete RC beginners, choosing the right servo can be confusing, so here are a few tips to point you in the right direction.
The standard, plastic bushed (bearings) type servos are fine to start with but come with plastic/nylon gears that can break easily in collisions. So, to protect your servo gears to some degree, make sure you have a good "servo saver".
Servo Savers come in a number of forms and are often included as standard on some RC Models. The best ones, in my opinion, are those that use a small spring to absorb the shock of the crash and are simply fitted in place of the servo horn.
For lightweight, small scale models, plastic geared servos are fine. But for medium to large scale RC models, I would recommend metal or titanium gear servos. These servos are by nature heavier and more costly than the plastic geared ones but are well worth the extra expense, for obvious reasons.
Digitally controlled Servos use a microprocessor based controller board. They are generally faster, provide better torque and centralise more accurately than the older Analogue types, but again at a higher cost.
As you advance in experience and skill, you might feel the need for something to match your lightning reflexes. Mos-FET, or simply FET Servos use Ball bearings and will provide the high speed response you crave, but at a price. However, if your budget will stretch to the higher cost, the improvement in performance can make a big difference.
Hints and Tips
How to avoid Interference.
1/ The first consideration when installing your Receiver into your Electrically Powered Model is to make sure it is well away from the Negative Battery terminal, and the Motor. The Magnetic field can cause stuttering type interference at times of high current draw (i.e., Fast Acceleration)
2/ Make sure the Ariel tube is long enough for the Ariel wire. The tip of this wire is highly sensitive and should be as high, and as far away from the Motor as possible (yup, its that magnetic field prob again)
3/ If all else fails, a simple tip that often works for all RC Model enthusiasts is to wrap the receiver in Aluminium Foil, to shield against any magnetic and external radio interference.
4/ As a last resort, to protect against servo twitch, try ferrite beads. (available at Radio Shack or Maplins) These are threaded over the red, white (or yellow) and black wires of each servo.
5/ If you are using a FET Servo, the installation of a choke (a small electrical component) in the positive feed wire will smooth out any current spikes and reduce the possibility of "servo twitch".
6/ Another thing you might try is a "glitch buster" or "stutter stopper". Basically, this is a capacitor that simply plugs into your Radio Receiver and attempts to keep a level voltage supply to the Radio system.
