42215 Mods Improvements Alternative builds And Attachments

[Auroralampinen]

Well, tommorrow is august first. And release date for the most hated august set;). 

In this topic you can share all fixes, mods, improvements, alternative builds. And attachments wich are compatible for the 42215 boom bucket lock mechanisms.

So have fun time. And share you amazing mods, attachments and alternative builds for the 42215 in this topic:).

Can't wait for this to become a thread filled with mod suggestions because nobody actually bought this set 

I'll start off!

1. Two L motors + independently driven tracks and motorized slewing, plus a distribution gearbox that allows multiple boom functions at once (or at least add more levers to the selector shaft)

2. Alternatively, replacement of the LAs with a pneumatic system (I assume the travel isn't high enough on the long cylinders, so perhaps you'd connect a long and short cylinder in tandem/series?)

Remove motorise coupler and route that power to attachment PTO for jackhammer or something else

The motorised coupler is an interesting idea, but I feel rerouting it makes more sense.

Not buying it.

So, I did a mod + some tiny tweaks, the main is using reinforced CV joints instead of UV joints inside of the boom, I think if we move the axle for the 2nd stage linear actuator to where the lime pin is then run this thru the gearbox, we can use the existing axle line for the motorized hammer drill.

Another option would be to just put a small motor in the gap shown in the first image then have extension cables going thru the rest of the boom and model to the battery box. But I want a turntable too, so I will be adding 2 more gearbox clutch rings, the functions will be:

• Turntable
• Boom stage 1
• Boom stage 2
• Bucket tiling
• PTO (used for hammer drill, and third party attachments, unused for bucket)
• Attachment unlatching

There is also a space to add a clutch ring in the middle of the gearbox.

Drive / skid steering would have their own motors and BUWUZZ in the substructure, so these dont need the superstructures motor/battery box.

This is for my semi RC mod, the other version will have no gearbox and be all motors,

Both versions will have LEDS

Quickly looking at the instructions, it shuld be possible to center the battery box and add another motor. This would allow faster gearing ratio and perhaps ability to control 2 functions at once.

I have finished the model besides the bodywork and I have decided that the hammer drill will have a knob gear that mates with another knob gear at 90 degrees  which is on the latching thingy, this means we can still remove the attachment but it can still be driven without having to align teeth, say on normal gears. The knob wheels obviously make the drill spin and hammer. Not sure if its possible to make those 2 functions independent.

I will make it so that the knob wheel doesn't prevent the bucket from being attached. Hopefully third party attachments will use my system too :D
