But if I attach a motor to it then it stops moving freely

Thanks DLuders but that does not helps... you see in that video the claw does not rotates freely (by freely I mean by hand) since its connected to the motor and only the motor action can make it move. I need it to move both ways... with motor action and with simple inertia, my claw serves to pick stuff and drag it as the truck is moving that's why I need it to move freely, just like a truck trailer for instance. Since I'm draging stuff I need it to move around just by itself following the truck movement (think of the stuff I'm dragging as a trailer), but I need to rotate it once its in the air before picking stuff up.

Hi there, I'm having a bit of a problem building a claw on a crane. I need it to rotate freely (the claw) and also mechanically... I'll explain better, I want the turntable to rotate freely all the time, but sometimes I also need to custom rotate it. My problem is that in order to having it rotate I'm pluging it into a motor, and of course then it wont rotate freely Its actually the same principle as a bicycle wheel, it runs freely until you activate the pedals and then the gears kick in and control it. Any chance this is possible? I was thinking of a gearbox to activate/deactivate the gears that go into the turntable but it wont work since it's still connected to the motor and it wont move. Not sure if I'm making myself clear Edit: Could I use two turntables one on top of the other? So that the top one rotates mechanically and the bottom one rotates freely? Problem is that the top one would maybe rotate on his own and doesnt rotates the claw.

Thanks tim

Hello EB community I'm planning for a new MOC and I'm going to need 2 XL-Motors and 5 M-Motors. From the LEGO website I can read: Ok, so this is my question, can I connect the 7 motors all to the same battery assuming I'm only going to use (at most) 2 of them at the same time? Or does the LEGO sentence actually refers to only connect 2 XL (for instance) and nothing more to a single battery? I think that I can connect all the motors I want to the same battery as longs as I dont use them all at the same time, so if dont use them simultaneously there should be no problem as they only use the battery when they are running (right?) Sorry if my question sounds confusing

I'm planning to build one of those soon: http://www.tigercat.com/images/stories/model_imgs/skidders/635D/635d_skidder_swamp_2.jpg It will be on a large scale and with use of pneumatics... Still waiting fir a lot of parts. I too love those logging machines =)
