TAMIYA M1A2 Displaymodel

From the other day, one of the RC tanks, M1A2 Abrams, is not in good condition yet. TORRO's RX18 receiver has broken its binding with the transmitter again and can no longer be rebound. The same phenomenon occurred with the new RX18. There seems to be no problem on the transmitter side. The reason is that this transmitter can be bound to other RX18s. I don't know the cause. Is the sound board (USM-HL-2) doing something wrong? ? I wasn't convinced, so I explained the situation to soundboard maker BEIER-Electronic and then sent the soundboard and RX18 to BEIER to have them investigate the cause. BEIER is a manufacturer that responds fairly politely. As a result of the investigation, they said that the output signal of the RX18 receiver should normally be 3.3V, but for some reason it is as low as 1.0V and cannot be received. The sound board (USM-HL-2) is sounder. They also don't understand why the output signal is too low.? They didn't know why it was so low and they couldn't repair it. At this point, I decided to stop sticking to the TAIGEN / TORRO transmitter and RX18 (RC for USM-HL-2), which are causing problems with RC tank models. I suggested to them that if they could change to the new product SFR-1-HL, which can use a general 6Ch or higher transceiver instead of USM-HL-2, and send it back, I would pay the difference. They responded to my suggestion. The USM-HL-2 is no longer on sale, and the replacement is the newer SFR-1-HL, which has higher performance. SFR-1-HL uses a general transmitter. The audio amplifier of the sound board is 20W, which is large enough. Functionally, the major differences from USM-HL-2 are as follows.
-The throttle curve of the main drive motor can be set freely. Sensitive control is also possible.
-The main drive motors (M1 and M2) can be set either by mixing or by themselves.
-Running mass inertia (light, medium, heavy) and brake strength can be set.
-It is possible to set the track recoil (none, light, medium, heavy) when firing.
-The turret rotation speed is variable according to the amount of operation of the joystick.
-The engine sound can be turned on / off from the radio channel or joystick.
-Battery can be used from 6 to 12V.
-The SUM signal (S-BUS) of the receiver can be used.
Other than that, the functions are almost the same as USM-HL-2, and sound files can also be shared.
It's the first time I've got this kind of Chinese Microzone transmitter (for cars, boats, planes, drones?), But the instructions are really unfriendly. There is something like a trainer jack or power jack on the main body, but there is no explanation. There is no explanation of the mixer function. (I don't use any of them ...) I was worried whether I could really bind to the receiver and operate it, but for now it is functioning stably. The lighting-related output wiring of this RC tank (M1A2) has not been completed yet, but I plan to set it slowly from now on.
