I have a new 9550 servo and noticed that the wire are a lot larger than the ones on the other sevros I have. Does anyone know why Futaba may have done this?

I Have been having some trouble between radio(3PJ radio) input and the cars reaction(seems to be slow to respond). I have let others drive the car / radio and they say the same. I have set all the radio setting to give 100% speed and response with no change.

I am running a nitro oval car with two sevros. The other sevro (throttle) is a 132 Futaba. I have 1200ma receiver pack that also came with wires the size of the 9550. I have ran the wires into a switch that has the normal size wire to go to the receiver Batt. input.

Could the servo not be getting enough voltage?

Could it be that I am getting a voltage loss in the switch wires?

Could the 132 be drawing to much voltage and slowing the 9550?

Larry,
what voltage is the receiver pack - I believe the 9550 needs at least 6v(digital). Also, have you made sure that it is charged adequately(voltmeter)?

Jason, the receiver pack is a 5 cell, 6 volt pack and is fully charged.

Possibly hook up a DVOM and monitor voltage drop while working the servos.

I would check the radio setting, I run mine in 4 cell oval with No problems. Checks the Dual Rate on the radio. Will the servo move full sweep? Maybe look in the owners manual and reset the memory model to default and start over again on the settings. most radios are faster than the servo speed, so you can only slow the speed of the servo down. I set my radio at 100% EPA both Direction, Dual Rate 18% to 30% depends on track. Also make sure the Servo saver is in good shape, might want to put a new one on. Check for binding in the steering blocks.

I likewise run mine in 4 cell oval as do many of my racing buddies without any problems. I think it may be that because you are running it with an Rx pack that the current demand may be bringing the voltage way down. You could try running a 6v Rx pack, or one with higher mahr's.
