Guys,
Need to understand more on servos,
The sites are listing servos by way of Fatuba, JR connectors etc. So the question is that are the servos tied to a particular Tx /Rx combination?

Pankaj


Pankaj,

The connectors on the servos have futaba connector or JR,Airtronics,Hitec,etc type connector.

Most cos had their own proprietary connectors. Now only futaba continues to use its own proprietary connector. The Futaba connector comes with a notch on the side.

Most of leading radio/servo manufacturers use common type of connectors now.

You can easily cut the extra notch out on the Futaba servos to make them look and work like JR.  Or use a file to shave it off.

True

Earlier they use to have different wiring also but that has all changed now. They use the same/common type of wiring.

Also what is a 'dead-zone'?

A dead-zone helps reduce wear and power usage by the servo by not responding to input until the input has changed by some preset/minimum amount.  Otherwise, if the signal is slightly unstable, the servos will work themselves to death.

Why dont you have a look at the following URL:

http://www.pongo-air.com/servotorque.html. There is a free torque calculator based on wing chord, wing span, speed etc.

Happy flying

Here is another site where the same fomulae are used but is online : http://www.csd.net/~cgadd/eflight/calcs_servo.htm

The air speed of the plane has to be approximated from the motor-prop-battery combination with other details of the plane. You can do that in Webocalc or drivecalc or motorcalc. All this is theoretical, but experiences have shown them to be manageable.

Happy Landings
