There is a new firmware update available for ALL brushless aircraft Electronic Speed Controllers (ESCs), including the Phoenix, Phoenix HV, Phoenix ICE, Phoenix ICE HV, Phoenix Edge, Phoenix Edge HV, Talon, Talon HV, Multi-Rotor and Thunderbird. This latest update is V4.22
- Bug fix for firmware version 4.20. Some users experienced problems reengaging the throttle after the brake was turned on at zero throttle. This issue only occurred when the brake feature was utilized.
- Adjusted software to improve performance under heavy load.
- Talon 15, Talon 25 and Multi-Rotor 25 had their current limit setting removed due to inconsistent operation. The software has been adjusted to measure excessive current using other means.
This latest version gives all ESCs access to features that were added to firmware version 4.20.
Firmware version 4.20 for aircraft ESCs has been “broken arrowed”. This means that any ESC that is currently utilizing firmware 4.20 and is connected to the new version of Castle Link (3.57.12), the program will NOT allow you to change ESC settings and you MUST update the firmware to version 4.22.
We also made some edits to the text of the “connection status” boxes to make it easier for users to determine whether their status is connected or disconnected. This was done to help red/green color blind users determine the connection status of the Castle Link and ESC.
