Default Ko 2123 Fet Servo For Nitro

Hello.

I own a KO Propo 2123 Fet Servo, and i was hoping to run it in my nitro car. But i have come to little problem, where do i plug the blue fet wire in order to get power?

At Ko's Web site it states that i can use it in a nitro car!

"Digital performance servo. High speed type suitable for all gas and electric cars. Features are as follows: 7.2V, torque 131.9oz-in (9.5kg-cm), speed 0.06S @ 60 deg., weight of 1.94oz, metal gears, double ball bearings, gold plated connector, size of 1.61(41)x1.50(38)x0.79(20)in(mm). You must use the 7.2V lead in order to opperate this servo".

HOW???????


Thanks

Edward Pickering.

If there is no solution i will have to trade or sell it. NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!

1- wrong forum section

2- Suitable for nitro racing BUT you need a 6-cell receiver pack, which is not that common on gas car. Not worth the trouble.

Later

You will need a six cell receiver pack (7.2V) and the 7V regulator switch (#36551). The regulator switch steps down the voltage to plug into your receiver, while giving you two 7.2V blue leads to plug in your servo.

Hmmm. These servos can be powered directly from a 6 cell sub-C 7,2 volt pack. So why not directly from a 6 cell reciever pack? The only possible issue, might be that you CAN'T use alkalines, since they are 1,5 volt instead of 1,2. So if you stay with 1,2 volt rechargeables, I cant believe it should be a problem to not use the 7V regulator switch (#36551)

Howdy

Usually 6-cell packs don't fit in nitro cars. Most pack holders are designed for side-by-side 5-cell packs. That's why I said it wasn't the trouble.

If that servo is new, you should be able to resell it no problem

Default 7.2V

You could solder it directly to a 6 cell receiver pack but you will have to use the choke that is supplied with the servo. The other problem with the 6 cell receiver pack is that it is 7.2V total, this may be too much voltage for the receiver to handle. KO receivers are rated to handle 3.5-6.5V. You run the risk of damaging the receiver at 7.2V. This is why we recommend using the 7V regulator switch.

Point taken, sorry if I misguided anyone.
