Duke Coupe from Dirt: Showdown (RWD Hot Rod Offroader) [Picture Heavy]
marco768 replied to marco768's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingIt drives very well with one L motor, the speed is around 1 m/s. The drivetrain has two pairs of gears,24 teeth-24 teeth and 20 teeth-28 teeth differential (Overall 1:1.4 ratio). If I reverse the motor output while the car was still moving forward the 24-24 set sometimes will slip, otherwise it works likes a dream. I have no idea of the power consumption, but I did notice it got a bit slower after playing with it for around 10 min, however the battery has already been used previously before I build this model though.

Duke Coupe from Dirt: Showdown (RWD Hot Rod Offroader) [Picture Heavy]
Hi all, Been lurking here for some time, and enjoyed viewing many of the MOCs you guys are creating. I ended my dark age 3 years ago with the Unimog set, however I don't have the motivation to join the world of MOCs until now. For my first MOC I have chosen to reproduce the Duke Coupe featured in the racing game "Dirt: Showdown". I think the simple structure and design of the car would be a good first practice on MOCs. For the build I didn't make much planning apart from approximating the stud length and width of the car, and deciding that it would be double wishbone suspension for both front and rear. Then I just laid all the available parts around myself and begin assembling freehand. I started out with the front axle, and decided midway that I want the build to also be IR controlled with a servo for steering and L motor for drive. The build then progressed to the centre section with the engine and exhausts. The exhausts took a lot of tweaking to make it look right, and even when I leave it I'm still doubtful of the appearance. I then skipped the main body section and begin work on the rear axle and the rear bodywork. Joining the front and rear took quite some time. Originally I wanted to have a detailed cockpit but the battery box, L motor and IR receiver took all the space. Designing and fitting the panels were easier than expected though. The roof was the hardest part of the whole build, I just couldn't get it to look right for a very long time. Later I accept defeat and decided on using flex axles again. In the last steps I find structural weaknesses (by using my hand to flex and twist the whole model) and strengthened them, then I finish the build with some last touches on minor details. The finished build: Engine bay details: Central PF elements: Detached rear body and roof: Detached front body and hood (One flex tube slipped out of position ): Belly shot: Specs: Length: 60 studs Width: 27 studs I don't know the exact weight but it is heavier than the assembled 42000 F1. I also don't know the part count since I didn't bother counting. IR controlled with servo steering L motor geared 1:1.4 with differential for drive to rear wheels (engine also connected) Speed: ~1 m/s Front and rear double wishbone suspension Wheelbase: 47 studs Track width: 23 studs Normally 4 studs clearance with 3-4 studs travel 1 stud clearance when fully compressed I am aware there may be some sub-optimal assemblies, some individual parts may not be 100% stably secured, and the bent axles may be illegal techniques. The ride height went a lot higher than I expected, the nose is also a few studs too long.and as a result the whole model looks a bit off-proportioned compared to the original. But I think the overall feel of the design is still there. Although the build was fairly basic and simple, the process was extremely fun. The exhaust turned out to all right once I attached the rear and main body. Watching the build take shape as it progresses was the most satisfying feeling I've had in a while. Thanks for viewing!
