1st Buffer-Pack 25F V4.12 for Helis 450-700

The new version of 1St Buffer has been upgraded.
You can use the buffer as usual, but switching off the buffer is now even more convenient.
In addition to the button on the buffer itself, the buffer can now also be switched off via a channel in the receiver with an assigned switch.
This is a great advantage, especially for models in which the buffer is installed inaccessible.
To do this, the buffer is connected to a free slot and a switch is assigned for this channel, which toggles it from -100 to +100.
The buffer uses its LEDs to indicate whether it is in the process of being switched off.
If it is in operation and supports the system, the red LED flashes as usual.
When charging, the green flashes.
When it is full, all LEDs light up.
After the switch is pressed, the buffer flashes red and green alternately for a short time and then switches off.
Don't worry if you use it incorrectly.
If you accidentally launched the model in the buffer from position, there is no risk.
The buffer must first be switched to the on position and then to the off position before it turns off. This minimizes the risk of switching off the buffer unintentionally. Likewise, some time passes before switching off, so that in the event of an accident, the switch can be quickly switched back to Pos on.
