Help with KO servo
 

Hey guys i have a ko ps-1001fet servo and i
have misplaced the resistor that went in the
fet booster power wire! The question is does
anyone know what the values are of this resistor?
Also i am now running a new novak GTB brushless
setup and the speedy doesn't have the little booster
wire hangin out of it! Does anyone know where else
i can get the power from for this fet booster wire!!:batman:
Any help is appreciated!!:D

You can wire the booster wire straight to the + terminal of the battery connection, or under the + connection on the PCB of the GTB.

In my experience I have found that the little resistor hasn't made any noticeable difference. I'll admit I'm using KO FM.

How could you misplace the external resistor on the 1001????

It's a bloody Inductor!!!!!!!

Inductance is measured in.........oh forget it.......:flaming:

As the other guy said, run the wire direct to the positive.
I run a 1001 with GTB this way with no dramas.

Hope this helps

I thought they were to stop voltage spikes causing damage to the electricals. :confused: or was it to allow the voltage to travel only one way. :confused: And I think it is a diode?

I think it was to help with glitching issues, mine broke off in 95 and its still going.

It is an inductor. I think the aim is match the impedance of the ESC to the servo. Much like a valve amp uses output transformers to match the anode impedance to the speaker impedance. Could be wrong though.

value of choke coil for PS-1001 FET
 

Hello guys,

sorry to bump this thread from 3 years ago, but I can give you the answer.

From the official KO manual, it's a choke coil of 4.7 µH and with a DC resistance of 0.5 Ohm or less.

For more info, it was set for use with a high-frequency ESC (from 2 to 10 kHz), in order to prevent servo errors or even damage, due to spike noise in the Ni-Cd (+) lead of the high-frequency ESC.


Hope it will help ;)
