Awesome work on your build!!! Looks great!

Hello all,

some pics of building the model:

the tracks:

I used the "Universalkette" bought by Conrad, cut them in the middle and soldered nuts. Stripes of polystyrol put them to the scale width.

Wolfgang,

On your dragline what transmitter style and how do you set it up?

What sticks perform each action?

Left stick center - no movement?
Left stick up - hoist up?

I am going to try using a DX6I on my Menck M251 conversion, wonder how to configure for ease of use and smooth operation .

Thank you for the videos of your projects!

Jim

[Rvjimd]

Wolfgang,

One more question. I notice in your video a bit of slack in the ropes as you operate. Do you have trouble keeping the ropes on the pulleys? Do you do anything special to keep them in place, or try to operate without allowing slack?

I have a lot of trouble with this on my drag rope coming off the bottom pulley. I think part is because the small line (thread) is so light weight.

Thinking I may need to make some sort of cover or something over the pulley?

Hi Jim,

the dragline:

sticks in center= no movement

left stick right/left = turning
left stick forward/back = lift up and down the bucket or the clamshell bucket

right stick right/left = lift up and down the boom
right stick forward/back = drag rope for the bucket or close/open the clamshell


One channel is for switching two controllers (switcher ON/ON wit a servo) from the drums to the driving motors


the backhoe

sticks in center = no movements

left stick right/left = turning
left stick forward/back = lift up and down the boom

right stick right/left = close and open the bucket
right stick forward/back = pull the bucket to the excavator


One channel is for switching two controllers (switcher ON/ON wit a servo) from the drums to the driving motors


Best Regards and hope i could help you

Hi Jim,

some rolleys are covered, all in the clamshell bucket, and the rolleys in the top of the boom

I have the same problem with slack in the ropes, to avoid this: excercice, excercice, excercice.........

After a time, its easy to operate with the dragline, also the clamshell. The most difficult is the backhoe. Reason: the german backhoes had tilting buckets, so you must operate with three drums in the same time

Wolfgang

Hi Jim,

the covered rolleys at the top of boom:

Very nice work!

Your rope excavator looks and works great Wolfgang.

Hi Jim,
...snipped...

Wolfgang,

When you say two controllers do you have 2 radio receivers in the model or is it another device which you switch functions? If it's another device where did you get it?

Thanks in advance

[pumptech]

Looks great and runs perfect !!:D
Great job Wolfgang

Hi Brian,

i have used a switcher like this:

http://img4.fotos-hochladen.net/uploads/schalteru27o3bjhnm.jpg

switching with a servo. The cables from controller goes to the middle, by switching the connection is on the right side or on the left side, once to the motors for driving, other for the drums.

If you have any problems to understand, i will show you a picture.

[Finster]

Thanks for the explanation. I misunderstood what you meant in your earlier post, but it makes sense now.
