Bruder Mack Truck poison motor

[Themonty73]

Hi guys please help,

I'm trying to convert a bruder Mack truck to rc for my step son, I've put a driven steering axle in and this is great but I have attached a poison motor to it and it goes to quick, I've tried to regulate the speed but to no avail I was thinking of converting a servo to 360 degree rotation to slow it down a lot but not sure would like some help on this please.

Thank you

I had the same problem with my King Hauler. I ended up getting a 65T motor. More torque and lower speed.

Hi rsd53,

Thank you for your reply. Did the 65t motor give a real scale speed, I think that's a better idea then converting a servo to 360 as that might be a little to slow ��

If your tight on room try a planetary gear box attached to the motor will work as they are about 35mm long.........

Hi,

Would changing the motor solve the problem or just add to it?

Thank you

I agree with cosett....a planatary would be just the thing....it's what I did when I converted my bruder Mack to Rc

Yes it did. The truck was a lot more manageable after making the change. In first gear I can creep very slowly. I just checked eBay and saw motors up to 85T for $25.

However don't rule out the planetary A n option.

Hi guys,

I'm even more confused now then when I started. Did you buy that complete as it is Mack daddy?
Have brought some motors ( Carson poison) but that was far to quick without a gearbox, then brought another with a gearbox fitted and it's far to slow..
help!
