SANWA programmable servo. The base model is the PGS-LH, which was a high-end model at the time. I bought it used, so the program is still the same as when I bought it. I used SSL to operate it with the program on the transmitter side, so I don't know the details. You should be able to use it for both drift and touring by rewriting the program with an M17 or using SSL. I used it for touring. After purchasing it, I switched to the LH II, so I kept it as a spare. It was almost unused in races. I used it last week and it works normally. Please consider it.
