    Thank you for building!Since this MOC is my early creation, there might be some problems. For example, the second axle(5.5L) in the transmission should be divided into two 3L axles(with stop) for reducing the friction.I'm not certain what makes that clicking noise in your build. There are few possibilities like:1. broken gears2. broken U-joints inside the boll joint

    In the last part of the video, I showed the reason why I had to change rear axle.In original setting, the torque of two hard coupled L motors was transmitted to rear half axle via a pair of knob gears. I chose knob gears because I thought they were strong enough to stand the torque, but they were not. They got damaged and degrade, then started to make squeaking noise. Apparently the performance became worse. So I decided to improve rear axle. Finished version has less friction, no worry about damaging gears or degrading performance.

    Thank you for pointing it out! I just fixed parts list.

    Hi, thanks for building! Did you use two PF receivers? I recommend using two SBricks because they can supply more current than IR receivers. My recent models were specifically designed for the use of SBricks on outdoor conditions. So IR versions may not work properly.
