When I replaced the motor with a powerful one and used it for a heavy tank body of 15kg, my PD SGB damaged the mounting part in front of the case.
I heard that PDSGB will release metal cases next time, so I will try them.
There is no problem with the metal case of HENG-LONG so far. However, it is not compatible with the base of PDSGB, so there are no plans to increase it.
