Man, I wish I had the money for all those parts... Just wondering, why are there 8868 wheels in the mlcad close-up pictures? Also, what does the buggymotor drive?
-
Yes that is kind of sad, I was hoping for some new motors... Well I hope the EV3 m-motor isn't just an l-motor. Edit: Hey wait! It says on the lego education that the servo has 20 N/cm of torque and spins at 160 RPM at 9v. That's 23 RPM faster and 3.3 N/cm more torque! The m-motor is just an l-motor tho.. Double edit: The new EV3 m-motor is slightly slower than the l-motor with just a bit more torque.

Lego would have to find a way to avoid twisting the axles, but I agree I think it would make a good set. -
[HELP] Gearbox Design
Junpei replied to Splat's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I think you should just try both gearboxes to see how much torque they can each handle and then use the better one for the final model. You will need a freewheeling mechanism for the smooth linear gearbox, right? -
Jeep hurricane V2
Junpei replied to GuiliuG's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I mean like in , I just thought it might because the shock absorber is mounted on a ball joint and has a fixed attachment on the portal axle. -
Yes those rubber tracks are awesome, too bad I don't really have many. :( I wish lego would make larger tracks with larger wheels for them for things like Sariel's tanks or just make rubber track inserts.

Junpei replied to GuiliuG's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Is that Machpherson strut suspension just upside down? Or does that 6l link count as suspension arm? Also does it have camber or caster and can it be steered by the shock absorber? Sorry for the late reply. -
41999 Tribute
Junpei replied to Zerobricks's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I don't know if he's going to make a video, you could always just see his mini 9398, I guess this one does have the winch function and smoother steering though. -
Tank Barrel Recoil System
Junpei replied to Voodoo Hand's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
One suggestion I would make is to not buy all the sets unless you want all the extra parts, you can just use bricklink for the motors and stuff you want. Also you might as well use an m-motor because you could always just press the button for it quickly for single fire and then hold it down for rapid fire. Also you probably shouldn't use knob gears for the drive, bevel gears are much smoother and can also give some gear reduction so it can have more torque. Edit: Hey I forgot the release date for the l-motor and servo motor on s@h is in only 23 minutes! I'll check on it very soon. -
Custom parts
Junpei replied to AKM_76's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I think he means that the turntables pop apart much less easily than 42000 hubs, where the 3-pin thingy pops out a lot. -

Junpei replied to AKM_76's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I don't think you do, I think it was made to remove the friction ridges. Maybe for a large u-joint? -

Amazing work cramming all the functions into such a small model! May I ask what the yellow 1x3 brick is for? -
8265 Front Loader
Junpei replied to therealjustin's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Nope, they're the same. You're right though, they do look bigger in the pics. Sorry for the OT, but does 8069 usually come with 6 pinhole wheels? I've seen the 3-pinhole ones in a review but mine came with the newer ones. -
Yes the micromotor can easily be used with technic especially because of the fact that it is 2 1/3 bricks high for easy mounting on technic bricks, but I think the usefulness of the xs motor vs the micromotor depends on the dimensions you're working with. e.g. the micromotor is only 3 studs long with the pulley but is also 5 studs tall if there are 1x2 technic bricks on the top and bottom. However with the XS motor it is completely the opposite, 5 studs long and 3 studs tall (or wide). But its shape is less blocky and more technic-oriented, plus having the advantage of fitting in a linear actuator holder, so I think depending on your situation it might be a real improvement.
-
Here is a motor I found that is perfect for the XS motor: With a 16 tooth gear, for scale: The motor I think could fit perfectly into the housing shown in the pictures and has the right shape. As for the specs, I don't know, I tore it out of an RC car so I can't identify it. However, I have confirmed that it has about the same torque and speed as an m-motor geared up about 20:1.

Doc's Mocs WIP
Junpei replied to Doc_Brown's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I am referring to the black axle and pin connector perpendicular double split (the black ones) on the left and right side on top of the portal axles. Sorry I am really late on that, I didn't notice the post date. -

Junpei replied to Doc_Brown's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Just wondering, why is one of the perpendicular split connectors upside-down (compared to the other one) with a pin in it? Edit: Sorry, I forgot to say that that is on the crawler. -
How to take apart older u-joints?
Junpei replied to Junpei's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Since the 4l u-joint is thicker and stronger, I can't get it to come apart that way. I think if a 4l u-joint was disassembled, it would be even harder to assemble again,but since the 3l u-joint's arms are more flexible, they could be easily put together. It was just an experiment before, but now I just want my broken u-joint not to be wasted.
