RE: Which (chinese) facctories make various brands of ESC ..?
PROGRAMMING ROUTINE FOR ALL THESE 100A / 120A ESC's is as follows:
First, make BASIC MENU selections, using Tx stick
1. Battery type LiPo / NiCd
2. Motor rotation direction Normal / Reverse
3. Brake on / off (aircraft); Governor on / off (Heli); Reverse on / off (car) -refers to positions 8 & 9 in later advanced menu
4. Aircraft / Heli
5. Boat / Car
Second, makeADVANCED MENU selections, using program box -choices shown for AIRCRAFT
1. Battery Type (LiPo or NiCd / NiMh)
2. Low Voltage Cutoff Setting
3. Low Voltage Cut-off Type (power reduction or immediate shutdown)
4. Motor Rotation (clockwise \ counterclockwise)
5. Timing Settings (to enhance ESC efficiency and smoothness)
6. Soft Start -Acceleration (for delicate gearbox and helicopter applications)
7. Start Power
8. Air brake response type -Fast / Slow, or in %
9. Air brake on / off
10. Motor pole number
11. Gear ratio
12. Max RPM
13. Average RPM
14. Download stored data
15. Restore memory
16. Backup memory
-Interesting that there is noprogram parameter for selecting Switching Frequency; and no way of Restoring Factory Default (as there is for most other ESC's)..
(Also: The O.S. / Futabamanual makes no mentionof Heli Governor mode, as do all the other ESC manuals ... -but Governor mode will be used in positions 8 and 9, if the Heli mode is selected initially in the basic menu ... )
Otherwise, the programmingfor these ESC's looks quite advanced and sophisticated-compared to other ESC'slike ZTW, or Airboss / Hyperion etc.
However, in my opinion, it is not "Rolls Royce" finely adjustable programming, like one getson a Jeti Spin Pro ESC.
