Monster Truck
This is my Sixth LEGO RC MOC. It was completed on 2/1/2014. It featured drive, steering, working V4 Piston Engine, Lights, and full springing suspension.
About this creation



After I've made my Pick-up Truck model, which I think was my worst failure since I've started making MOCS, I've decided to make a successor of that model which can be lighter, have a simpler suspension, have a more efficient drivetrain, and most of all, drive faster. The Pick-up Truck's drivetrain's efficiency was extremely low because I've housed the drive motor in the front of the vehicle for 4x4 drive, which is pretty far from the wheels. This model had rear-wheel drive only, had a single L Motor for propulsion, and it even had more functions than the Pick-up Truck, such as the V4 Engine (My first time ever using a piston engine) and lights. I've decided to give the model a gray body and 9398 wheels, and I did, and it worked out pretty well.

I've first decided to even try out an independent suspension in the front axle, and it failed because it was large, weak, and I should put the links almost perpendicular to the wheel to make it work, but I didn't because of space so the wheels steer when the suspension goes down. I've never gotten an independent suspension to work because I don't have the specialized suspension arms. Yes, I've gotten some from the 9392 set, but unfortunately their ends are ball joints instead of a ball socket, which makes them useless except when used with piece 6571, which has a small steering lock and hard to use with the Servo Motor. The 9392 also does not come with piece 6574, which is a rack with ball joints designed for this type of independent suspension. Instead, it uses a mechanism that can backdrive almost any mechanism connected to it due to its design, so I had given up trying to do it and gone back to a basic suspension.

Another problem is the model's weight distribution. The two suspensions for each axle are not similar, making the rear of the model stronger. I've eventually put the Battery Box and the IR Receiver in the back for more weight, and it worked.

At the end, the model was fun to drive and quite fast. It used the same gear ratio as the one on my Street Buggy, but was a little faster. The suspension never collapses, and the steering worked great.
