Servo Checking Setup
Is there an easy way to test servos? Do you have to connect to a receiver in a plane or can this somehow be done outside a plane? Can you hook a receiver to a battery and the receiver to the servo?

RE: Servo Checking Setup
There are inexpensive devices you can purchase to test servos without them being connected to a receiver. I can't think of the names off hand, but try a Google search or check Horizon, Tower Hobbies, or any of the companies that make electronic stuff for RC, like ElectroDynamics, for example.
I see these devices at RC trade shows and in magazines, but I have never bought one. I wish, sometimes, I had. Sometimes, they call them Servo Exercisers.

RE: Servo Checking Setup
You can also build your own, any square wave generator that can create a variable positive going pulse 1.5 to 3 milliseconds in duration every 20 to 50 milliseconds. An LM555 is easy to configure to that state. Perhaps you will even find a schematic for it at http://www.uoguelph.ca/~antoon/gadgets/gadgets.htm

One of my better investments.

RE: Servo Checking Setup
Thanks PJ_TankPilot for the info.
I have some servos that do some erratic twitching or chattering. Sometimes I want to just toss them. It seems like you can get them to be ok again by taking them apart and looking inside and tring to work them a little. This tester would allow me to put them on it and see if its working rather than putting back in a plane and testing.

RE: Servo Checking Setup
If you get the MatchMaker, it is designed for the universal servo plug. Servos with the Futaba J plug will not plug into it.
An easy way circumvent the problem is to get a Futaba J servo extension and remove the J tab from the male plug.

RE: Servo Checking Setup
MPI sells Universal servo extensions that will work with Futaba, JR, and Hitec. I have carved off the tab on Futaba J extensions, but you also have to bevel the edges of the connector or it will push in hard and be difficult to remove.
