Hobby Engine Crane overhaul
Well ordered the Hobby engine crane a while back ,have had it for a few weeks ,letting my 2 yr old play with it some in his sandbox,he's been giving the slipper clutches a good workout ,lol !!
Will give it a overhaul ,want to build a dragline bucket for it soon , first to go through the model remove the 49 MHz gear,will secure the slipper clutches and try the factory gearboxes to run the spool for the boom,bucket lift.Ordered a few parts so far ,bruder replacement tracks,rc4wd fairlead ,slipring Ordered a small winch from rc4wd for the bucket winch should be in soon. Have a few pics so far of the breakdown

Re: Hobby Engine Crane overhaul
Well little more progress on the dragline ,got the bucket built ,the tricky part was getting the cable length right for the bucket dump , took a few trys to get it right ,still need more practice on the controls .

Re: Hobby Engine Crane overhaul
Great job! I decided to replace all of the motors and gearboxes but now looking back I should have just eliminated the slipper clutches like you did. I'm just afraid 40ft of skyline is going to just shred those gears. I also really like what you did with the tracks but I am going to try and make all metal ones. Key word there is try

Re: Hobby Engine Crane overhaul
Pumptech-your dragline seems to work pretty well. I did notice a bit of "jerkiness" in some of the movements but sounds like you have plans for that. Nice work overall. Did I here real dragline sounds in that? Where did you find that? Neat idea!!
