I spent the past 3 or or four days work on this cybertronian megatron tank from revenge of the the fallen film. its not really a finished moc yet cos the sets has a bit of trouble turning and I think I messed up the suspension so some rebuilding will probably be needed I only have two medium motors at the moment. anyway here are the pictures: and a video of it in action and also scaring my dog a little lol if anyones got an tips or a better method for powering four tracks with just two medium motors I'd be happy to hear them

nope I don't wanna say to much right now in case it winds up not work for some reason. I might consider trying a skopio motorization at a later date though

so is it possible for a PF box to power even one rc motor or would create the same problem?

so I built a quick cheap buggy that would run round in a fixed circle. I used the power functions battery box and two motors from the 8366 RC version use a special adapter wire brick i bought off of ebay. for some strange reason the rc motors couldn't put down enough power to even move this very simple moc. when I swapped these out for a simple PF medium motor linked to the wheels by two medium cogs (one size up from smallest cog size) the vehicle instantly worked and happily ran in circles until turned off. so I'm just wonder if anyone knows what the problem might be? the motors are a bit old by now but as far as I know they still work and the pf should certainly be able to handle two RC motors since it'd be power at the most the equivlent of two XL motors

it won't be huge probably a bit bigger than an average RC so maybe about the same size as a hoovers base? I don't have any XL motors right now so I might have to go for a simpler option.

the reason I'm asking is I've got a an idea I want to try out which will use four sets of tracks to power it. I'm probably gonna go with the option of simply running the right and left tracks off of seperate motors to allow for turning. I earlier mocced (now destroyed no pics sorry) up something which had four tracks the front of which were attached to a special turntable with a worm gear attached so you could rotate them and the vehicle would run in a fixed circle until turned off(didn't work sadly). I was just wondering if there are any other practical turning options for a four tracked vehicle rather than simply a motor for left and right tracks and reversing one to turn?

ok so I've just built up a new steering rig the gears work and can now run to the steering wheels through the universal links. the problem started when I added in the motor and tested the steering. the problem is is that motor moves the steering bar much to fast. so its either turning fully left or fully right with no middle grown and no way to reset the steering to neutral since when you release the stick the motor stops rather than resets to a neutral postion. heres the pictures of what I've built so far I tried use a work gear setup to slow the motor down this is too slow and means your spending allot of time steering and trying to steer the other way or make the wheels go straight.

as best I can tell thats rear wheel drive only with front wheel steering? what I want to do if possible is to have two motors one that will power the steering function and one and one that will power the wheels attached to that steering rig. EDIT: wait yeah I see how it works now. yeah thanks this looks really helpful.

hey guys! I'm planning on building a motorised RC version of the star wars clone turbo tank which uses ten wheels. after looking at a few similar wheel layouts I found that most people used 3 steering rigs two at the front and one at the back so I decided to do the same on my moc. but I also wanna see if its possible to power the wheels on the steering rig to a motor so my creation won't be forced to rely only 4 of its ten wheels for locomotion. I've built a cheap prototype to see if I can achieve that but I've hit on problem here are the pictures of what I've made so far from the top and botom: so the problem is I was planning on powering the wheels through the two towbar pieces (not sure what their proper name is but you put axles in them and tilt to a certain extent and still turn a full 360 degrees) anyway when I link the two bars together the axle connecting them won't stay lined up over one hole so I need to know how to successfully connect some gears to them so they can link up to a motor turn and still steer in both directions.

I've done a couple of pictures. cameras really low quality but anyway:

well I got wait a few days for an extra motor two IR recievers and controller to arrive but at the moment I'm considering taking the wheels building the drive and steering system as what would basically be a seperate moc and either locking it on to the upper clone tank body or if it proves to incompatible start building it back up. not sure which yet cos I was toying with the idea of rotating sensors (those bits on the sides of the cargo hold doors) and turrets which would wind up need a allot of gear winding round itand would be virtually impossible on the orginal set without drill holes in some of the pieces my only major issue is I don't have any pieces for steering setups and I can't work out how to make motored version that wouldn't use the steering bar pieces

not really, but basically I wanna take 8089 set leave it largely unchanged and use a pair of motors to power the wheels and rig up some sort of steering system. so ideally all the changes would be at the botom of the set

I'm planning on making an RC star wars clone turbo tank but I don't have the parts to make a normal steering system so I wanted to get some ideas I'm thinking about maybe building a tilt based steering system since lego clone turbo tank set turns by tilting the whole body in the direction you wanna turn it.
