  1. Yup. Going to be 19 studs. Inverting the wheels will make rear narrower than needed. The reason I am using hubs is beacause of the width. This way I can have solid structure to start with, instead of using liftarms to build it. Plus, in the long run if I ever want to convert it to offroader, I can always change out gears as necessary.
  2. I believe it looks wider than the actual truck because of all the pieces between the wheels. Actual truck is roughly 2.4m wide. I calculated the scale of lego wheel compared to actual one, and got 1:12.5. Used the scale and width of actual truck in Sariel's converter and got width measurements of 24 studs and 19.2cm. I think once the whole thing is built, it will look fine.
  3. After trying to mount drive train, I ran into several geometry issues and clearances between shocks and tie rods. Ended up rebuilding most of it. Used perpendicular axle/pin pieces on the axles going to differenatials. That elimited some wobble and also provided support for axles that hold shocks. Connected new drivetrain to a frame and tested geometry. Whole thing feels solid and robust. Thanks for noticing that. While rebuilding, I strenthtened the locations of the gears to remove wobble and possible slippage. Was actually thinking about 5x7 frame. Unfortunately, that frame would eliminate spaces I needed to install shocks. I might rebuild using those frames if the rear is too unstable.
  4. I decided to start with rear drivetrain. Been thinking about ways of building it and came up with two methods. First attempt came out too bulky. Its good for a semi truck, but I need something more compact for pickup. Due to offset location of diffs, wheels with shortest axles had weak mechanical connection to drive trivetrain. For the second attempt I used offroad hubs to create less bulkier structure. I like it more because it's lighter, more compact, and wheels have strong connection. Next step is to create a frame to support the drive train.
  5. To avoid ownership confusions, I only post my own images. I posted two links in above post to give an idea of what I am shooting for.
  6. Sure. Here are couple links.
  7. Hey everyone. Decided to start my first MOC. Can't learn to swim if you don't get into water . Only I feel like I am jumping into a shark tank. I always liked dually pickup trucks with crew cabs. Regular ones have two axles. Some people convert them into three axle 6x6 beasts. Why? Cuz Amurica! For my build I decided to go with 43.2 wheels and 64.2 tires. Thanks to Sariel's extremely handy scale tool, I was able to use tires to create scaled measurements for the whole truck. I ended up with 64 studs bumper-to-bumper length and 25 stud width. I layed out dimensions on the table, and was amazed how hefty it looks . Since I dont have XL motors, I wanted to use two L motors. After laying out the dimensions, I am thinking that two L motors won't be enough and I might need couple XLs. As for PF features, apart from 6x6 drivetrain, I will only do headlights. I have been thinking about a winch and fifth wheel, but at this point not sure how I will incorportate them. Once I am building, I will definitely consider the options. Looking forward to your feedback.
  8. Got a question about leaf springs. I assume the price on shapeways is for each, and not a pair. Is that correct?
  9. I liked the 2005 gt more. This one looks like design team didn't have consensus so they mixed all of their ideas into one car. Lego version might look better.
  10. Regarding the servo, I kind of got lost in my own thoughts . I meant to say that without a way to calibrate rc servo, it wont return to exact center of the specific model. I was thinking about wiring rc servo into LEGO receiver, but from what I understand, receiver won't be able to calibrate exact center to return to. T_Tank, I agree with you on hubs that support bearings. But I guess at that point, it is better to get rc car .
  11. RC servos return to center because of ECS. So I guess a person will need to source the whole system: servo, ecs, tx/rx, and motor. Probably will need weakest motor so the gears dont get stripped. And even then, how viable would it be without closed gearbox and lubrication.
  12. Since first time I seen Hoonicorn, I was wondering if someone will give it LEGO makeover. And here it is. Amazing! :thumbup:
  13. Picked up hot rod 42022 the other day for $15. I am not too excited about the model. But for the money seems like an ok parts box. Dont know if to keep for myself or just give to someone as present
