    Of course I do. But the rules are in Russian :) I can upload the file so you can translate with google if you want. There are some base rules. But in practice every race organizer makes slight clarifications: allow or dissalow RC-tires usage, custom controllers etc.

    Hi! More then 15 models have participated in the LTT race in Moscow this September. Some of them were really cool! Video from the race (there is no sound, just turn on any melody you like :)

    Hello all! There was an outdoor truck trial challenge in Moscow a few weeks ago. Here are two videos. Enjoy :) video 1 video 2

    I've updated the sbrick firmware and proportional acceleration works now. But there is a lack of calibration: a have max acceleration with 1/3 max angle of the controller stick.

    Hi, imurvai! Thanks for a really useful app! I've tried it and it works fine but one thing. There is no proportional control. In other words I can't accelerate smoothly. Full power only. Is it a problem of a controller (I use the same one as you do)?

    +1 for stearing mechanism! I'll study the ldd instruction:)

    The second version of my Easy rider trial truck. The suspension remains the same. RC4WD Mickey Thompson 1.55 BAJA mtz scale tires are used. The main feature in the truck is programmable differential. The truck is powered with two PF L motors. Each motor drives the wheels from on side of the truck. Programmable differential between right and left wheels is realized with custom remote control by DGI. Control features are used: 1. discrete acceleration and steering 2. while steering the inner wheels are being slowed down proportionally. More photos.

    Great work! I like the speed adjustment mechanism especially. Are you going to make the NTP synchronization? ;)

    Here you can find a few photos of suspension.

    Cool! Can't wait to see the video!

    When I've opened the topic I expected to see a dinosaur. The first suprise was to see the crane. The second suprise was to see it's transformation! I've never done any transformer on my own, but I've seen my friend's transformer made with Merkur metal parts - it is really hard task to construct. So congrats to you! Your model is cool!

    The model is dismounted now, but I'll look if I have some other photos of suspension. Are you interested in front or rear suspension? Some time ago I've made a device for speed and acceleration measurement based on NXT ultrasonic sensor. I've measured the acceleration of the model with traditional electric scheme and with two battery boxes plugged in parallel. In the latter case the acceleration was around 30% greater.

    I like the way roof rack is done and fog lamps are fixed! I'll keep it in mind :)

    It is really cool!

    Here is a model I've build for "Mad Max style" lego rally challenge. The primary in the model is its rigidity and power. The exterior is secondary. To rise up a torque I've plugged the AA PF battery box (with over-current protection bypass) in parallel with RC receiver. The PF battery box is switched on with PF M-motor plugged to the third channel of RC receiver. As a result the model drives more steadily: .

    Set # 8674-1: Ferrari F1 Racer 1:8 I can't say it was the most difficult. But it was the set I've delighted every moment of building!

    I've started when I was a child in 80-s with some brick sets made in Soviet Union: When I was at school in 90-s I played with some fake lego bricks. It was my first acquaintance with lego mechanics. I could only dream about some native lego-technic sets that time. They were too expesive. The sets that brought me out of my 'dark' age were Tow Truck #8285 and Motorized Bulldozer #8275. I've bought them in 2007. The first serious challenge was Tow Truck motorization. Then I've started the construction of 4wd models. And I'm doing it now :)

    What IR receiver version do you use? My servo doesn't work with IR receiver V1. With IR receiver V2 - OK.

    I like RC4WD Mud Slingers 1.9 Tires Soft:

    I have no special room for construction unfortunately. So I just use a table in the kitchen and a few organizers It looks like this: A few ready models are stored in book shelves.

    I don't use any lego CAD software. I use computer on my work and I want to have a rest from it while lego-building :) Several years I've experimented with different 4x4 suspension types. The development process was the following. 1. Thinking out the idea of front suspension mechanism. 2. Building a prototype of suspension and the chassis just to test how suspension works in practice. 3. Running some out-door test-drives. 4. Fixing wicked places and rebuilding the prototype. Repeating steps 2-3 unless the prototype works good. 5. Building other model parts. 6. Final test on Lego Truck Trial competition :) - Some principles I follow: - the good mechanism is the simple mechanism - the less parts you use the better - the mechanism strength should be enough for comfortable using model in it's scale environment - don't copy other's solution. Catch the idea and make your own implementation - keep in mind resistance of materials theory and mechanisms theory if you studied any At last the best way of construction - is YOUR OWN way of construction.

    Excellent mechanics! I like that it is made very compact.
  24. zver
    Yes, the battery boxes were plugged in parallel. They let motor provide more acceleration. With one AAA battary box buggy motor works bad.
  25. zver
    I've started using the same scheme a few years ago. I've plugged two AAA-PF battery boxes via two IR-receivers to one buggy motor. The result was awesome. I've won two lego rally races with it!
