[WIP] Audi TT LPE Drift Car- Shaping the body
JJ2 replied to Epic Technic's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Looks really good so far, are you going to put a sticker on the headlights? Another thing, you probably need to brace the gears better, I think they will slip under stress. -
Making technic parts
JJ2 replied to StormFalcon32's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
That would be possible but the Lego tolerances are very small so one mess up will make the part too lose-too tight. Another option is 3d printing, mainly using Shapeways. -
Axle Collection Thread
JJ2 replied to efferman's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
The suspension looks very stiff, I think the softer setting would be better. -

Steering for Fast Vehicles
JJ2 replied to rkkm's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
It seems you have put the hubs on upside-down, the way they are now will actually decrease the handling, I would also recommend tilting the front suspension assembly to gain caster, moving back the top or moving forward the bottom wishbones will give you caster but not real caster. Tilting the whole assembly will make the suspension more reactive to bumps while having the wishbones in different places will not do that. -
[MOD] Extreme police RC racer

+1 on that anyway cool creation, besides Rebrickable do you have any pictures of it? -
[MOC] RC Hovercraft
JJ2 replied to JamesJT's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
When I first saw it I thought it was real, as @aeh5040 said cool illusion of the skirt inflating, too bad Lego motors are not powerful to actually power a fan to inflate a bag. -

I think I might build this MOC, I'm mostly missing cheap liftarms but I'm missing 18 dogbones- 632 replies

Steering for Fast Vehicles
JJ2 replied to rkkm's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Don't gear down the servo unless its using gears with very little slack like a 12:24 or bevel gears only, spur gears have a lot of slack. Avoid using axles longer then 3L and if you need too use a axle extender with 2L axles to hold them together so it does not have much slack in the axles from them twisting. Use caster angles, they help a lot, and have a slight toe-in to make the wheels want to pull into the chassis and that makes the car want to drive strait. -
Steering for Fast Vehicles
JJ2 replied to rkkm's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Yes it will, I forgot to mention but make sure to give it a caster angle, that will help a lot. -

Purism
JJ2 replied to Erik Leppen's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I'm sure I'm a well known non-Purist since I extensively use non-Lego parts in my MOC's, but building with purist rules is fun also. I have actually am starting to miss just using Lego and my next few MOC's will most likely not have any 3rd party parts in them. -

Do you want suspension? -
Steering for Fast Vehicles
JJ2 replied to rkkm's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I would recommend using a very robust custom made steering hub and using wishbones instead of the 6L links if you car making it suspended, if not I would recommend about a 30* caster angle and a kingpin incline, they will make the steering have very little bump steer with will improve performance. I might make a moc'up of one and post a picture -
[AMS1] 42056 Porsche 911 GT3 RS Crawler 4x4
JJ2 replied to Zerobricks's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Impressive performance for its size, I will be entering the contest soon, I just dont have very many Technic sets to Crawlify thought Do you think you could lower the body a bit? It just looks maybe 2-5 studs to high -
Self-Powering LPE Idea
JJ2 replied to RcRacer99's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Completely impossible, friction, air resistance, and the laws of physics do not allow this. The closes thing to something that will spin forever humans have made a a perfectly balanced metal wheel on magnetic bearings inside a vacuum, but even that will stop when the magnets wear out.- 7 replies

Ripster V16
JJ2 replied to Zerobricks's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Very cool, the suspension works very well, much better then I thought it would. Imagine what it would be like if you had it on trailing arms, it would float over everything. -

LEGO MOC: Themed roller coaster
JJ2 replied to Gijserman's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I really like roller coasters but I think I would pass on this one the speed it accelerates seems to much for me. jokes aside stunning creation, how many black 2L pin extenders or the things that make up the tracks are there? -
I mainly sort Beams by type, like frames and dogbones in one, the two different L beams in their own different containers and the regular beams by light and dark (dark = black, DBG, DG, red) (light = LBG, White, NXT white, yellow) I have all my lime color parts in their own container because I was to have easy access to them. For pins I put 2L black ones in their own spot, 2L blue axlepin and 3L friction pins share the same spot, and all the other non-friction, 3/4 pins, and so on that are for more special uses all are in 1 container. I put all of my axles in 1 box, no sorting whatsoever. For bushings I have them all in 1 box too Connectors are sorted by 6536 and 32031 type connectors All suspension parts are sorted by springs, and other suspension parts Gears are sorted by bevel and spur

BMW U2-P1A
JJ2 replied to Zerobricks's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Very innovative, the hubless wheels are very nice, how well do the wheels turn? For a engine could you mesh another smaller wheel to the rear one and use that?
