Default I think I fried my servos!!! This is what I have hooked up...

I have a two Cirrus 4.4 submicro servos, a Hitec Electron 6 receiver, a Trick RC 8 Cell Battery (9.6V, 370 mAh NiMH).

When I got my crystal to try out the system, the servos started acting all weird - spinning 360º really fast and then getting hot. Now, only one works while the other doesnt respond. Whats going on!??? Could it be my battery having too much voltage?

Thanks,

Juan

Hi;

How did you connect the battery to the receiver - directly? Or did you go through an ESC with a BEC?

If you connected directly, I think yes, something may have burned up (did that myself, the hard way).

If you were using a BEC to limit the voltage, I think the receiver and servos should be okay.

I'm contemplating some of the Cirrus 4.4's myself, but the "universal" plug gives me concern - check your documentation for both the receiver and the servos, and make sure the hot, ground, and signal are all connected properly. Is it possible to plug in the universal plug backward?

Dan.

it would certainely fry the hole damn system connecting the huge battery directly to the reciever, perhaps you got lucky? are you using a BEC that can take your volts-amps?? how can your servo spin through 360 degrees, of course if you took off the mechanical feedback within..

Thanks Guys,

Sounds like you are trying to make roast receiver and stewed servo! [X(]! you shouldn't in any way, connect a battery above 6.0 volts directly to a receiver. It sounds like your receiver is OK, so your servos would probaly be running hot, the internal motor is probaly on its voltage limits! That still doesn't explain why you servo is running through 360 degrees! Are you using a modified servo?

I found this about your receiver--

The newest aircraft receiver from Hitec is the 6 channel, Electron 6 micro FM. Weighing in at a mere 17 grams, this receiver promises to perform up to the solid reputation carried by all Hitec dual conversion receivers. Offered in two version's compatible with all modern FM transmitters.

Type 6 Channel Dual Conversion FM
Range 1+ Mile / 1.6 Km or more
Operating Voltage 4.8 volts - 6.0
yes! 6 volts![X(]

please tell me what you you are to receive,from doing this!![sm=spinnyeyes.gif]
