| FET servo
I recently read the directions for the Tekin Rebel 2 and glanced at the part about the spare red wire being for a FET servo. What is a FET servo? Is this one of the bigger 1/4 scale servos that need the seperate power supply? And if so, can you wire the red wire of a 645mg to this wire and power it that way? |

FET is an acronym that means Field Effect Transistor, which is a common component in the amplifier circuit for digital servos. Due to these amp circuits digital servos have a higher amp draw than a standard analog servo. It is these FETs that burn out in digital servos when they're under a constant strain. http://www.futaba-rc.com/servos/digitalservos.pdf The FETs in digitals will burn up where an analog will not. The "fact sheet" on Futaba's site says "Just one disadvantage", but FET failure is another disadvantage. Last edited by JasonInAugusta; 10-22-2006 at 10:19 PM. |

Thanks Jason. The reason I asked is because the Rebel 2 I have, for some reason unknown, will not power on without having a reciever pack plugged into the rx. Tekin says that it is probably the switch, but the switch was removed and the 2 wires were joined together to trouble shoot wether the switch was bad. Which is isn't. At wits end trying to find a solution.

Thank you Unholy, you are a Godsend! That's what I was looking for and trying to explain to Tekin. It's funny it should do that, It was never ran with a reciever pack before I got it, and ran with 2 645 mgs with no problem. Taken out of a running truck and sat for a week or two and when it was put back in to another truck, nada. Exact same setup as the first. Go figure.
