Re: Liebherr LTM 1030-2
 

More up date.
Received my (2) 1000 RPM motors from China today.
Also had to make my hubs, as no one had any for 4mm shaft,(that I could find).

So will see how they work as soon as I find some way to mount then to Truck.
Any input welcome. Did see some on line, look like a block with hole for motor.

Do you mean 100rpm by any chance?
The hubs look good!
Brass tube with brass collar? Collar drilled and tapped?

Attaching motors:
press into plastic tube
glue into other tube
screw into mounting holed on front surface of motor, angled metal plate
use hose clamps to secure motor on metal/plastic profile
...
?

JensR, Set Screw.

Thank you for the input, on mounting.

Two Motors for $14.98 shipped, they are 1000 RPM's.

They test fun good on 4-AA.

Will see how it goes. LOL

Drive Wheels

Re: Liebherr LTM 1030-2
 

Looks good!
So you make "only" the front axle steering?
Sorry to repeat myself, but I am slightly concerned about the motor being billed as "1000rpm". That sounds quite high and I would have expected (as I said earlier) 100rpm to be more realistic - but if you have done the tests and it works, that's great!

Also, what scale is this?
The first post says 1:25, but this looks bigger?

Cheers
Jens

Re: Liebherr LTM 1030-2
 

Well, maybe 100.
Rear drive only.
Will be 1/14 scale. Used info from member to find size.

Thank you for looking.

Re: Liebherr LTM 1030-2
 

This sounds as if you are barely using the throttle?
That crane is going to be fast ;)

Re: Liebherr LTM 1030-2
 

Yep..... Will need power when Crane is mounted.

Re: Liebherr LTM 1030-2
 

Power is proportional to speed times force.
So, for a given power: If it is fast, then it is weak.
I'm a bit worried that you indeed might have the 1000rpm motors, in which case you won't be happy, I fear.

Re: Liebherr LTM 1030-2
 

Thank you for input.
Well can be changed if needed.

Re: Liebherr LTM 1030-2
 

Seems to run really smoothly!

Re: Liebherr LTM 1030-2
 

Hi JensR, thank you for the comment.
Should be better with a speed control.
