here are some points for Tankers that wanted to buy low cost tanks and invest more money with the high end upgrade parts.
We will try to explain in simple English terms, not using technical terms.
This is about the electronics, the system that drives the left and right tracks:
1. The present motors that drives the tracks are at 380type.
In Mabuchi terms, it is called RS-380SH (4045)

RS380 are stock motors in Tamiya's tanks.
HL/Mato/WSN/Matorro/etc did not use the original RS380 but a replicate made by a low end China factory.
similar motors can replaced the said motor, so long as the specifications are within the same category.
2. In order to drive the motor correctly, a correct driving current must be supplied from the circuit board. It is the current that is moving the motors, not the voltage.
3. For the tanks, it is driving two motors, that requires to move the motors in
a. running at some direction of rotations
b. running at opposite direction of rotations (circuitry and algorithm complications are in this situation)
4. Due to that requirement, the design of supplying current becomes more complicated than just driving one motor (just a car, plane or boat).
5. Mato/HL/WSN/Matorro/etc design of the motor driving circuitry are very simple. They use the low end FETs and the simplest design that requires the minimum number of FETs to drive the motors.
Furthermore, the algorithm used in the initial run of motors is poorly managed.
Hence, you will see Tankers blowing up the boards, and using cooling tools (cooling fins, heat sinks, cooling fans, etc) to remedy this situation.
6. After changing to metal tracks and/or using high torque gearboxes (IMPACT called them TUs), it added extra load to drive the motors. Which in term, requires more current to pump out of the circuit.
7. Hence, if Tankers were to upgrade to metal tracks and/or high torque TU/gearboxes, careful selection of motor driving circuit must be changed too.
If you used the original circuitry, they might not be able to drive the tank, and/or the tank will move at an extremely low speed.
This has nothing to do with a "weak metal gearboxes", this is all about the "power" driving the motors.
For Tankers' reference purpose only.
