What is the difference between the S136G-MG and the S136L-MG ?

Please be advised the S136GM is retract servo and S136L MG is just regular servo.?

My Slow Stick with the ICS100 speed control. The ICS100 worked fine for about 25 flights and started to cut out and then I have to reset the throttle, even if used different batteries, channels on my Hitec radio. Also the servos twitch slightly every 2 seconds. Could you advise me where is the problem ?

From your description, it might be the problem of your servo, not ICS100. Please be advised ICS100 is without brake, GW100 is with brake. It will be cut off automatically while 4.2V.

May I use Mini servo motor in another application not related to airplanes.Can you please supply the voltage ratings and most important the wiring for each color.i.e.red = clockwise, etc

With reference to your inquiry concerning Mini servos. Please refer to our web site at http://www.gws.com.tw/english/product/servo/mini.htm
JR-- (Orange-->Singal) (Red--->Positive +) (Brown-->Negative -)
Futaba-- (White-->singal) (Red-->Positive+) (Black-->Negative-)

About ESCs, BECs, and servo failure ?

#1 set-up - you are correct, it is simply out of spec and will not work at all, or for long. The BEC chip will be almost constantly overheating and shutting down, until the point of failure (closed circuit) with no output.
#2 is fully within specs, and does not pose an issue for even the BEC to shut down from overheating at all, UNLESS a servo is stalled, or the pot is damaged/partially burned/has dead spots and so on. Even good small servos when stalled can draw surprising amounts of current, and with pot damage can basically be a direct short.
The only real (or induced) damage any controllers BEC can cause (we all basically use similar linear regulator circuits) would be from providing less than 5v in an overheating and shutting down situation. Mike from Hitec would know if a constant shutdown-reboot cycle would do anything negative to a servo. From what I know about them, I don't see how it could be harmful#1 set-up - you are correct, it is simply out of spec and will not work at all, or for long.

I just bought one of your packages that comes with 2 servos, a motor controller, a NiCad battery pack, and a receiver. When I got done charging the servos and such the servos just kept twitching and would not respond to any commands that I would give them. The same with the motor controller the motor started but I had no control over it. What should I do?

If you have JR or Airtronics transmitter then you need to purchase the flight pack with JR receiver. If you have Futaba or Hi-tec transmitter then you need to purchase the flight pack with Futaba receiver. Because of high and low deviation please shift / positive or negative.

Please can you tell me the absolute maximum value for the supply voltage for a "PICO F STD" servo?

Please be advised the absolute maximum value of "PICO F STD" is 8 micro second. We would suggest you to use 5 cell (6.0V) battery pack.
