    Hello, everyone! I built 4WD off road pickup truck being inspired by the set 42029. It is not a copy of actual truck, but some details look similar to Ford Raptor and Toyota Tundra which I referred to. Weight: 1570g Features, 4 wheel drive with 3 differentials 2 XL motors for driving Servo motor for steering Working V8 engine Working front and rear LED lights via power function switch Suspensions Front: independent Rear: live axle Openable hood, doors and glove box:) Lockable tailgate Detachable bull bar and roll bar Double wishbone front suspension is the same as 42029. Which means that front axle has a differential and CV joints without portal hub reduction. They cannot handle much torque for offroad driving. So I put portal hub on rear axle. Gear ratio is 3 : 1. That can handle enough torque. This setting enables central differential to act as torque vectoring diff. Front wheels recieve 25% of torque and rear wheels recieve 75%. Thus this Truck has good offroad capability. Three differentials and pairs of CV joints works smoothly, and they did not break or snap. You can change body color, and choose the type of battery box: 8878 or 8881. Video: Building instructions and more pictures: https://plus.google....64977943/albums I hope you will like it! Edit: I forgot exhaust tailpipe in all pictures. This is the final version!

    Thank you, guys! About a month ago, I was planning to modify and motorized 42029. Certainly the origin of this MOC is 42029. Now I'm making instructions. Hopefully, I will share it next weekend.

    It's done! Building instructions and more pictures: https://plus.google.com/u/0/photos/117021167471864977943/albums I add it to Rebrickable. Soon it will be available.

    I'm working on Tatra's instructions. I spent a week in building the chassis. I think it would would take another week to finish the whole. Swing half axles. Gearbox with 2 XL and M motor. Back half of the chassis. At this point, I've taken 125 pictures. Full instructions would contain more than 200 pics. I hope to share full instructions in the beginning of October.

    Steering system is not like real. It's not robust but works with enough precision.
  7. Madoca 1977
    I wanted to drive it outside, but It was a rainy day. Someday I will make the video of my trial trucks crawling outside.

    Because I didn't have any proper planetary hub reduction ideas. And I thought using portal hubs was simple and robust solution with minimum friction.Total gear ratios are 9:1 and 25:1. High: 12/36 - 8/24 Low: 12/20 -12/20 - 12/36 - 8/24 Since each half-axles contains 36t bevel gear in it, they became bulky and stable. Never bend or twist. Steering is simple gear rack and 9L links. 1st axle is steered by 12t bevel, 2nd by 8t gear. Yes, it's not like real.

    Hello everyone, My new creation is a big Tatra. It is my first 8x8. All problems of size, weight, friction and powertrain were the most challenging for me. Total weight: 2790g 2 hard coupled XL motors for 8 wheel drive without differentials. They are connected to each output of V2 receiver #2, powered by 8878 battery of left side. (Motors of the rest are connected to V2 #1, powered by 8878 of right side) 1st and 2nd axle are steered in different angles by 2 L motors. M motor for 2 speed heavy duty gearbox. 9:1 (high) 25:1 (low) Working steering wheel and V12 engine. Openable hood and doors. External roll cage and LED lights are easily removable. This is my suspension setup. The central axle is free from the friction by the force of suspension movement. Each 6.5L springs limit the angle of swinging half-axles. In these limited angles, bevel gears smoothly engage. Since the building process was complicated, I haven't made instructions yet. Hopefully it will be available in a few weeks. I drove it in high gear in most part of the video. Despite heavy weight, not a single gear was damaged. In low gear, it is surprisingly powerful.

    Looks cool! Thank you jantjeuh, I was one of those who wanted to see the Vette in black! :wub: Most of the red parts can easily replace in black. Except for 19L soft axles and bushes. About 19L soft axle, I have these alternatives. Front is #3 connector and 16L. Rear is 16L and #4 connector. Since the set 42026 have 3x 16L soft axles in black, they would be less expensive than 19L. About bushes, I have few of them in black. They are not common in recent years...

    I made that mechanism.

    I just updated the model. You can see new parts list and instructions. https://plus.google.com/u/0/photos/117021167471864977943/albums
  14. Madoca 1977
    Some people mentioned that the center axis (LBG 7L axle) might be disconnected. Before finishing the model I thought of that possibility. But I had no problem when shooting the video. I just fixed it. Tomorrow I will update the instructions and parts list.
  15. Madoca 1977
    Thank you all! I just have submitted it to Rebrickable. I think it's easy to build. I used the switch to reverse right side of motor.

    Hello everyone, After finishing Corvette, I built simple RC buggy. It is lighter, faster and more agile than my preceding buggy. Weight is 590g. Total 312 parts. Video: Building instructions and more pictures:https://plus.google....64977943/albums Rebrickable:http://rebrickable.com/mocs/Madoca1977/pf-buggy-2 The performance is not as good as RC buggy motor models... But I enjoyed the buggy driving over obstacles at a good speed.

    I got these tires from the set 8041. They are proper to my mid scale cars. But BrickLink taught me that they are not common in recent years... Thicker tire (62.4 x 20) would be accurate, but it requires me to build larger scale model.It was the birth of this MOC when I found that LBG axles fit to the chrome front bumper of Corvette C3. Subsequent WIP pictures are as below. And the final version.

    I read this topic. http://www.eurobricks.com/forum/index.php?showtopic=89999Since my Corvette is a mid scale model, using two clutch gears was a simple and effective way to use L motors with coasting behavior. With normal 24t gears, Corvette accelerates and stops abruptly a bit.
  19. Madoca 1977
    Thank you all! And yes, I need axles 4.5L with stop and thicker tires. If I had 19L soft axles in black, I would build another Vette in black!

    Hello everyone, This is my new creation, a copy of 1970's Chevrolet Corvette. It is a medium scale model driven by two L motors, steered by a Servo motor, and wearing 56mm tires. Weight is 1060g. Thanks to using 24t clutch gears, it smoothly accelerates and stops. Suspension travel is short and ground clearance is about one stud or so. But it is enough for driving on tarmac. Features, Four-wheel independent suspension. Working retractable headlights and tail lights. Openable hood, doors and 'trunk' (for access to 8878 rechargeable battery). Removable targa top. Video: Building instructions and more pictures:https://plus.google....64977943/albums I added this MOC to Rebrickable. I hope you will like and build it!

    You don't need second (red) 8t gear. Just rotate 20t bevel and 8t gear by 45 degrees. My supercar and new MOC use this.

    I saw some reviews of my models. That was my pleasure. On his(her) review, I watched my models with different eyes and found out some good or bad points which I couldn't noticed by myself. I thought this experience can improve my building skill. Above all, I'm happy and honored to know people enjoying my models. Because when I was a child I had a dream to be a Lego official set designer.
  23. Madoca 1977
    Sorry, I can't remember my early works. If I build a dump truck once more, it will be a new version.
  24. Madoca 1977
    Older models including Dump Truck and large Supercar have no instructions. They were disassembled years ago. At that time I didn't have any thoughts of making instructions.

    Thank you for building! It's easy to change color scheme. I hope someone will bring this MOC to Lego Truck Trial competition in your country. As far as I know, there are no Lego T.T. competitions in Japan. In driving outdoor, I think it would be better to change knob wheels to 12 and 20 bevel gears. With yellow lines and LBG wheels. With white lines and unimog tires.
