RE: Which (chinese) facctories make various brands of ESC ..?
PICS OF 100A ESC's:
1st pic shows O.S. OCA-1100HV 100A 50V (HV) ESC (does not have fan)
2ndshows LogicRC Hawk (Fusion) BL100A OPTO ESC / LiPo 4~12 with fan
3rd shows SJ PROPO 100A HAWK PROGAMMABLE BRUSHLESS OPTO ESC(4-12CELL LIPO), with fan
4th shows Tahmazo Pro.C Max HV 120A ESC, with fan
5th shows Robbe ROXXY BLControl 9100-12 Opto, 100A ESC, with fan
6th shows Mega Power Future 120A HV OPTO ESC 12S with fan
7th shows Futaba MC9100A 100A ESC, Li-Po 4-12 Cell (does not have fan)
These ESC unitsare all obviously identical(only difference is O.S. and Futaba do not have a fan / heat sink) .These unitsmust all be manufactured in same factory.
Clear that O.S.and Futaba are manufactured in same factory that also makes: LogicRC Hawk, SJPropo Hawk, Tahmazo, Megapower, Robbe -and probably other brands in addition.
It is also clear from a previous post, that these ESC'sall use the same programming box -showing they are indeed identical.
