Replacing HL Rotational unit motor

[MichaelC]

Hi all,

I think I have posted this question before...... Is there a easy replacement of a faster motor into the HL rotational unit ? The HL Leo has a rather large turret cog ring and the rotation speed is super slow. I know that there is some rule around the colour of the ends of these motors (130s ? Is that what they are called ?) but don't seem to have much link.

A link to a website would be great !

Thanks !

Hi Michael

Try these.

should get it down to about 10 second per turn.

As I use the IBU2Pro in my Leopard with the same large turret ring and 360 rotation is down to 5.5 seconds

Hi You can use the black cap motors fitted to the BB gun ,this makes the turret turn twice as fast as the normal motor , I use them and so far havnt had a problem.

Thanks guys......... 971wright, I will dig and see if I can find a BB motor. Tankbear, do you think these are the same as the one you posted:

Hi Michael,

Yes those motors look the same type I used.

Timed it before with the blue end motors it was 25s for 160 degree or 50s for a whole turn (320 degree).

I swap the motor out and put in the black ended one as per 971 and also put in the blue-end resistor as well (just in case..... They have a different number on it) and I got 8s for 160 degrees or 16s for a whole turn (320 degrees).

First of all thanks 971wright......... At least it is reasonable now still no where near the real thing. Question now becomes does the resistor matters ? WIll it go even faster if I remove the resistor ? Would that burn out the motor or juice out the MFU ?

I am going to install the white end ones when I get them. Tankbear, did you use the same ones for your elevation as well ? Also, what resistor, if any, do you use on them ?

Thanks guys.

Hi Michael,

Yes also tried in the elevation unit

I didn't bother with resistor (it lowers the voltage and speed). I found as your pushing 7.2v through a 3v motor it will eventually fail, but took a year and as so cheap not a big problem.

Took out the resistor and got another 2s off on a full turn (320).
