it is now but should be better with new thin liftarms- 35 replies

rc chassis for new hubs WIP
z3_2drive replied to z3_2drive's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Thanks! But I'm still waiting for the parts to arrive But this long wait has allowed me to rethink and perfect a few aspects of the chassis-I changed the rear suspension a bit for more travel and a more buggy-type look, and the front shock mounts have been braced and connected to the servo, along with both receivers being placed in an efficient and compact manner. Pictures: ^steering angle seems good. Enjoy!- 35 replies

rc chassis for new hubs WIP
z3_2drive replied to z3_2drive's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
UPDATE: As I mentioned in another topic, I bought all new suspension hubs and new thin 5l liftarms with axle holes from lego direct, but I have not received them-hopefully soon this week. In the meantime, I have made a completely new chassis-same power but lighter and smaller And here are pictures ^also went for a mostly light bley chassis this time... ^like the previous chassis I'm using placeholders for the new hubs, and the light bley half-bushings are placeholders for the new +ooo+ thin liftarms. ^there'll be decent travel in the front and rear axles ^three 20t gears will in theory keep the differential from skipping teeth... ^my 10 volt batteries are held in place by a simple cage and a liftarm on either end. ^front side. ^I'm glad the pin w/ bushing exists-it's a must have for easy deconstruction. I'm happy with this "chassis ver. 2" , hope you are too!- 35 replies

good thing I bought another servo and two more l motors soon after the 9398 , so they were still reasonably priced and available, but this still doesnt seem fair.

Allround Car Competition Movie
z3_2drive replied to mahjqa's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
do you have a pair of the new f1 hubs(rear) mahjqa? it seems like the only part that fits the missing space in the ldd shot... EDIT: never mind I saw the comments about it on flickr... -
rc chassis for new hubs WIP
z3_2drive replied to z3_2drive's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
do you guys think this chassis is worth a rebuild? since I have no hubs yet I made a makeshift wheel placement that will model final outcome and it looks... weird(too wide for its wheelbase), but dont want to risk taking this apart-maybe i'll make a separate lighter, downsized chassis, possibly live axle in the rear- 35 replies

rc chassis for new hubs WIP
z3_2drive replied to z3_2drive's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Finally, I've finished the chassis but i'm calling it a prototype because I don't know how it will perform. It weighs in at about 864 grams WITHOUT wheels...so most likely will be a high speed but slow acceleration... It has decent steering angle (im using placeholders for new hubs) --- I made a quite aerodynamic-looking underside: Hope it turns out good once hubs become available for good prices!- 35 replies

Ok, here's a delayed update- stiffened the suspension by changing for extra hard shock, and moved the mounts one stud out on each side. Built a large section of the chassis and placed batteries in. Made a simple flat bottom to keep electronics clean and free of dust, but I expect scratched panels sooner or later... Photos: Now just need to figure out front axle/steering which will be hard without new hubs... I hope to go through with this and finish it!- 35 replies

z3_2drive replied to Zerobricks's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
and all the parts hold up without breaking?? if so, sweet! I've designed new axles with 1 xl on each but havent got around to building a chassis for them... I'm going for the fast, lightweight approach- 20 replies

Age Restrictions
z3_2drive replied to Someonenamedjon's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Welcome to EB! I am also under 18 but I read the rules of the forum and obey (except age rule ), I think that is enough to deserve an account -
agree with above statements about differentials...but one other thing is that by moving the shocks to the outside may increase stability, but it GREATLY reduces suspension travel, I can tell you that, but I guess it's ok because this model has so many other features great job :thumbup:

How to open an RC Motor?
z3_2drive replied to pint14's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
do you have the correct cable? if so, try putting the end that fits onto the motor at different angles (vertically/horizontally) because one of my motors doesnt work when you have it on a certain way, I'm guessing it has to do with polarity... -

The previous attempt at a large scale car failed because it was not strong enough for the drivetrain, and my attempts to make a sturdy chassis around it were not so great because of the vertical placement of the buggy motors. I have sitting on my desk now, a 2nd attempt at a large scale rc, with a much more simple and robust suspension, which will eventually use the new f1 hubs, at the moment I used the dark bley mog hub because of it's dimensions. I placed the buggy motors in a clever fashion, so there are many bracing opportunities for the rest of the chassis and the rear axle. Because of the eventual weight of the vehicle I had to put a combination of various shocks to get a perfect balance between soft and stiff-soft enough that it will absorb bumps and jumps but stiff enough that it wont bottom out (hit the ground) because there is a lot of travel and not that much clearance, and I will use the same wheels/tires as on the 42000. Photos: Enjoy!

Project LARGE [car]
z3_2drive replied to z3_2drive's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
because- its rare and probably expensive, have heard of some units having connection problems, the unit itself is huge(I think a new design could probably be smaller) and you cant connect the new pf servo to the unit, and I heard the built-in steering output is not strong and ends up with terrible steering performance in a heavy vehicle. BTW its a perfect time to say this project has been scrapped and something new is in the making- 7 replies
