My new creation is a big scale Baja Truck. For the first time, I used two SBricks for better control.
Weight is 1920g. It is almost the same as gsia17's awesome Trophy Truck.
Since I do not have RC buggy motor, I had to build it using PF motors.
Honestly body color is not the best. I just have many red #3 connectors and wanted to use white 19L softaxles. I think it is easier to build it in all white. And using stickers will make it look better. (Though that's not my way:)
This Truck is powered by two 8878 rechargeable battery boxes, and propelled by four L motors geared 1:1. Two for each side of rear wheel. Left side of drivetrain is connected to fake V8 engine. Steered by Servo motor, which is connected to steering wheel. Two pairs of LEDs are put behind the front lights. Adding more LED for roof light bar is possible.
I tried to make suspension movement like real Trophy Truck. Front module including independent suspension is connected to main chassis at positive caster angle. Rear suspension is solid axle with long trailing arms. Front suspension travel is about 5 studs long, and rear is 7 studs.
It was challenging to achieve proper driving speed on bumpy ground using PF motors.
The result was not the best, but was acceptable to me. Sbricks did their job so well.
As expected, some parts in drivetrain got worn. Especially knob wheels. While I was shooting the video for two hours, they did not affected driving performance. So far they just made noise which is heard in the video. But someday they will certainly be damaged too much and need to exchange.
EDIT: I have fixed the problem of knob wheels. Improved drivetrain doesn't damage any gears.
