SNIPE

Oh my bad, I have another idea, it is to take the plastic rims out and use the tires with an old technic 1/1 bush (not 1/2 size). Here is the rim and tire assembly: I hope they are not too curved on one of the top edges however. because that's bad for grip.

Ah, thanks for the tip! :)

Are you sure? i don't think LEGO would miss out such a detail, the tires you posted had rings on the sides of them and are slightly ballooned on the top where as the tires i highlighted in the image are flat on top and have flat sides.

DLuders, You can only order the parts from bricklink in bulk quantities ,so I don't need to have like 40 odd of the old style technic bushes. I am only using them as wheel rims for my go cart project so I would only need a small amount of them (2 wound be enough but maybe I would order a few more as spares).

Here is the parts panel in Lego Digital Designer, the two wheel types are placed in the workspace as-well beside each other.

ok, in the brick panel of lego digital desighner there is two tires that look identical, they are this in real life. what is the difference between the two identical looking tired in lego digital designer and is there two real bricks that are that of what it says in lego digital designer.

it fits the new bush fine but what about the old one, i want tw tires on the old wider one

hi, there is two of these in the legndesighner brick list whats the difference betweeen them

hi, do you think that these tires will fit on these bushes in the grooves or will they be off and not in the groove. i need two tires to fit on this bush as it is a replacment for using two modern technoc 1/2 bushes. here is the old bush and here is the new bush (the 1/2 size) or here is the tire now that i would still have to use another 1/2 bush with that for the 3rd tire since there is three tires in a row. also note that i chose the old bush because of the overhanging part that is on one side, it should therefore stop the tire from rubbing on the chassis.

here they are: here they are: part 1 part 2 you may need to refresh the page until you see the video i will probably put an LXF file up with instructions and put up the C code soon.

i have the video, i wll upload it ASAP it will be better in a way with motors because they can hold up some of the weight when it is balancing however the wires stop it from pivoting as much.

sure, i will make one asap i will have to move each motor by hand however because i don't have any batteries or a program for it to run,

hi, i just finished making a robot, it was originally meant to just crawl along on the three motors and there was no detectible wheel when i got into it a bit more i made it stronger and added weapons/sensors and armor i started building this robot at around 2:45PM the features are: when the robot is in the standing up position: can move forward or backwards , can transform into the other position by using the motors the robot is controlled by RF wireless communication (IR or BT) the colour sensor is supposed to be a missile tracker, the touch sensor is meant to be a altomiter and a plasma ray (the if the wheel is attached then that is meant to split the beam into 8 weaker beams. the ultrasonic sensor is a radar and keeps track of the other enemy and of the earth around it., the two yellow balls in the storage bricks are means to be remote controlled explosives (C4). the motor that has the grey striped blade can also be used as a ram, or since it pivots, a shield for missiles and other things. when in the low down position: all weapons/sensors are still functional like in the upright model. it can move using the wheel or just the motors/legs i am trying to add each of these links to an album where each actual photo is on one page, then i can post the link of that page here. i did not put each image on here because that takes up even more space.

gah, i have had to put that on hold because: it has issues still, the thing needs more gears and now it is kind of getting pointless because the gearbox in the 8448 is just as good for its size but isn't as well equipped. because the technic challenge finishes on either the 21st of 23rd of august, the car will take around a year to make if i focus on it and not put it aside for a week or something. maybe was being too realistic for LEGO. anyhow, my entry for the challenge is 'fastest 4 wheeled vehicle.

yes, i started this model on July 31 and i have nothing built yet so id better get a move on , i had the rear wheels almost done but then i had another idea on an assembly of some rear wheels , i have to order the parts for that, i have to order the motor as-well and that's about it . i will probably be working day and night like the good old days

ok thanks

hi, are you allowed to send more than one photo of your creation, and can you print the technic challenge logo on paper and put it in the same photograph of your creation do you have to have the logo in every photo is the deadline the 23rd or august or the 21st of august is it ok to use some lego system parts as long as thr model is mainly technic

are you sure, the outer and inner diamiter of the top of the rounded brick is only worth the height of a flat plate or 0.1L of an axle (tha'ts half of a 1L axle or quarter of the 2L axle that is attached to the rod as part of the metal axle assembly im not too bothered about the rim coming off the axle for now just as long as it enables the wheel to spin with the axle. oh i have just ran into another blimmin' problem the metal axle has a stupid end cap so i wont be able to put an axle to axle connector to the end of it. it looks like i will have to be using the second assembly after all

i might add my current project into the competition, fastest 4 wheeled lego vehicle it is a go-cart.

if you were wanting to fix the one that is not working id suggest going into the Electro Tech Online chat-room and asking somebody, adding a post in the forum and they should be able to help with that. (back on topic) yes it is easier to buy a new unit but f you fix one you save money and you learn something. maybe it is not worth the hassle. it might not be the tower that's the problem or the brick so id make sure you know which one is faulty before buying a replacement.

can you post an image of the 1x1 round plate thanks i could also use a 4L axlle with stop or a threaded 4L axle and have nuts on either side of the rim

ah. well i tried another type of tire on a bush like that before and it worked fine but the tire was not what i was looking for but now i just took a look in LEGO digital designer and i put three bushes together and three tires on each bush, it was good because it was wider than the default tire and still a slick tire: the default tires are attached to the assembly. i will have to text both the default and the new assembly out in real life.

sorry i changed the images, please see the edited port, there is no round bricks without the hole in the stud there, and there is no round bricks with the rod on the top, there would not obviously work with the axle. i assumed that the rod on the metal axle is the same diameter as the typical rods such as: for example when the metal axle is fully inserted in the round 1x1x3 brick should be half (or 1L of the 2L axle) of the 'x' part sticking out of the larger hole and most of the rod (probably 1.5L) or the 2L rod of the metal axle sticking out of the smaller hole of top stud of the rounded brick. the top studs have holes in them which the rod goes through.

as the title explains, will this technic axle: http://www.bricklink...em.asp?P=pinpw2 mesh with any of these bricks: http://www.bricklink...tem.asp?P=3062b http://www.bricklink...asp?P=3062bpb37 http://www.bricklink...asp?P=3062bpb36 http://www.bricklink...asp?P=3062bpb35 http://www.bricklink...asp?P=3062bpb01 note that i think that the last round brick will have more grip than the others because the plastic is not glossy, its matt surface. or the transparent blue one might work because it may be more grippy down to its dimensions and shape despite it probably being used in the same molding or pressing machine. the metal axle will also probably be grippier than plastic. the axle will to in the underside part of the brick and the rod that is part of the axle will stick out of the hole in the top of the brick.

i have tries using the below rims: with my current tires, they work fine but i still need the wheel to spin with the axle so that the power is transferred to the wheels properly. also, adding two tires beside each other is a bad idea i think because it effects the wheel balance and adds weight and makes it more likely for failure the assembly, i like the tires i am using because ive always wanted to make a co cart with them but never got round to doing it. i am thinking about using a metal axle that has the small rod attached to mesh with one of the following parts: http://www.bricklink...m.asp?P=3062old http://www.bricklink...tem.asp?P=3062b http://www.bricklink...tem.asp?P=3062a http://www.bricklink...sp?P=3062oldpx1 http://www.bricklink...asp?P=3062bpb37 http://www.bricklink...asp?P=3062bpb36 http://www.bricklink...asp?P=3062bpb35 http://www.bricklink...asp?P=3062bpb01 here is the axle: http://www.bricklink.com/catalogItem.asp?P=pinpw2 when the axle and round brick are attached it will kind of look like this: http://www.bricklink...asp?P=6933cpb01 http://www.bricklink...asp?P=6933cpb02 http://www.bricklink...tem.asp?P=6933c i just hope that the axle meshes with the rounded brick even if it allows around 30% slip, the other alternitives i have tried with this brick have unsuitible properties because they allow for too much slip (around 85 to 90% and they don't stay on the end of the axle.) i need a certain amount of slip because if you have too much the power from the motor will be wasted and not sent to the wheels if i was using a technik engine where it does not deliver power then the wheels would be the power source but they would not transfer the power to the axles and the engine+axle transfer assembly.
