Hi Guys,
Recently we have been discussing wing designs and I thought, their is more to radio control aircraft than just wing design, I know this is Brian's specialty and he has put forward food for thought but we need to branch out.
There are flyers out their that have experiences with various aspects dealing with RC aircraft. We have members that revel in Glow/Nitro motors, they can sit you down with a six pack and bend your ears for hours. If you mention electric motors and ESC's, someone will jump in and give you all of the specs for different aircraft. If you don't know the difference between a Ubec or Sbec someone will explain.
Myself I would like to explain the difference between a digital or analogue servo.
Analog servos operate based on voltage signals (pulses), Digital servos use a small processor to receive and direct voltage pulses, Digital servos are six times faster than analogue servos BUT depending on the application you intend to use them, outlaying money just to have digital servos can be misguided when analogue would suffice.
The newer versions of Spektrum transmitters and receivers allow alternating between 11ms and 22ms frequency depending on your servo's, you cannot mix them. If you are having trouble with your digital servos not centering or chattering, look into what frequencies you are using. Analogue servos are slower, they use way less power consumption than digital servos and cheaper. In gliders and foamies I prefer analogue servos, why!! because you are never in a hurry with a glider, foamies tend to overreact with digitals and next thing you know you have tip stalled.
If anyone has any questions or comments please jump in.
Next week we will look into what digital servos have to offer vs analogue.
Cheers
