    There would be nothing to brace the lower black bewel gear so it would click horribly when torque would be applied.
  2. Mechbuilds
    Would be very easy to build this using only one XL motor.. Not sure if it'll have enough torque though.. Final gear ratio to the wheels is: 7,001:1 If i add a gear ratio to the XL motor, it'll further modify the final gear ratio. Already at 7:1 it's not that slow but it has okay amounts of torque with 2 XL motors. I think there is no way to fit 2 xl motors here.. So i give up, i hope one is enough to power this massive hulk of a moc. Here is my gearbox how to drive the fake engine.

    I'm having a hard time trying to picture what you mean. Could you show me a picture? Just realized the black axle is one stud too short.. Space between front and rear unniversal joints is 13 studs. So i have to use a axle to axle connector to make the axle a little bit longer.. Oops.

    That wouldn't work because then the motors would need to face front and back instead of left and right. There isn't enough room for them to be mounted in that way. There is barely enough room for the XL motors to face eacother in sideways position if i already modify the frame itself to make room for them.

    I don't want to stretch the frame. But i think i could modify the frame so an XL motor could be mounted sideways facing the middle. Then i would have 3 studs of room between the XL motors. I could use 4 tooth gears to turn the drive sideways and then just add two gears to redirect it down. Bracing the middle would be the next problem so the 4 tooth gears don't pop off. If i use 5 studs of room in the middle so an 7x5 frame would fit between the XL motors, the xl motors then would pop out 1 studs from the sides out of the frame. Also if i use 4 tooth gears (knob wheels) would it deliver the power smoothly or jerky?

    Hope the bigger picture helps to visualize. (that black 12 long axle on the front is reserved for a fake engine that can be in total 10 studs long)

    To make it an uneaven number, the XL motors have 1 stud gap between them. So they're 11 studs width in total. On the center of that 11 studs width you go 2 studs down to the axle. So that's 3 studs from center of that 11 studs width to the axle itself. But yeah the the XL motors can be mounted upright if i modify the chassis a little bit. (the center reinforcing beam is in the way for them to be mounted upright.) But i think i can manage to modify it without too much structural weakening. If the XL motors are mounted upright, that'd mean that there is no room for that M motor to drive the fake engine. So i'd have to make a gearbox that spins the fake engine. Totally possible and there is room for it. Next issue would be: How to attach 2 upright XL motors to an axle that's going horizontally in the middle.

    EDIT: If i use 3 of 24 tooth gears and mesh them with an 8 tooth gear, that'll make the moc very very slow and i'm not convinced one 8 tooth gear can handle all the torque alone. That's why i asked if anyone has a different gearing solution? Barely with 2 stud of room behind the motors if pushed against that grey beam. No room on the sides or down. With gears, only 1 stud of room, and if i put a beam to brace it, no room behind motors. Very very tight fit.

    Basically i need to squeeze two XL motors inside that tiny gap. (imagine the second half of the frame attached to the gray beams end.) The black axle on the bottom with 2 red bushings is drive for front and rear axles. Both XL motors need to work together to spin the black axle. If possible, the tan axle on the top would spin the fake engine. I was planning on using an M motor to spin the fake engine so i can display it with engine running without moving the moc. But for now, How can i drive the black axle with those 2 XL motors? Don't have an LDD for this yet.

    While talkign about buwizz and not wanting to make another thread, buwizz can be run with a powerbank attached to extend playtime? Any suggestion what powerbank should i get? This powerbank would be only used with the buwizz exclusively and i would glue lego beams on the powerbank so it could be connected to mocs via studs. It also needs to be a budget powerbank so probably chinese would suffice. Has anyone ran buwizz with a powerbank?

    amazing work on the front grille.

    be creative with lego technic connections. Ball joints are cheating after all Post pictures of your current progress. Easier to help when you got something to work with.

    https://www.eurobricks.com/forum/index.php?/forums/forum/179-lego-scale-modeling/ I think the chapter is misleading. But there is also a lego scale modeling chapter

    Could this be moved to the system section? While it's a good moc, it's not technic.
  15. Mechbuilds
    You could use these technic panels for those toes. It would be very cool if you could build the entire moc without bionicle joints.

    This might help: If your mech is small enough, you can get away with having the friction gears built in the legs in order to get the hip joints more compact. If you're building a mech that's larger, i suggest having two friction gears mounted in the hip instead. How tall of a mech are we talking? EDIT: If you're building a smaller mech, use the pin holes on the small turn table as pivot points. If you're building a bigger mech, use the large L beam as the pivot point and attach the small turn table to the L beam. Use 2 long beams to make the hips widen and close like a hinge. They have plenty of friction. If you make a moc like my grizzly then you'll need double friction gears or it will just flop down due to the weight. Oh also those gray 3 long pin with axle end when put trough two beam holes, it will have massive amounts of friction.

    Nice clean little moc! Well done!

    Will the sierra be an 4x4 version or the RWD version?
  19. Mechbuilds
    You could also just go to aliexpress and order fake chinese 9.5L springs. Ordered 4 of them because real lego ones are 10 times more expensive.
  20. Mechbuilds
    That's cool!
  21. Mechbuilds
    Oh wow! There is a god!

    My face when i voted for the sierra

    EDIT: Wrong thread
  24. Mechbuilds
    Thank you for doing these experiments!

    If that ain't compact, nothing is.
