VSpeak Auto-Air-fill is an only ~220g light onboard compressor for pneumatic chassis mechanics, brakes, etc.

The pressure range can be adjusted, as well as some other parameters. Once set, the desired pressure range is regulated fully automatically.

A previously required pressure reservoir can be significantly reduced - or it can be dispensed with entirely.

There are several operating modes for Auto-Air-fill:

• • Autonomous Automatic mode   (remote control independent)

  • Automatic mode Servoport       (requires a servo output to which a 3-position switch has been programmed)

  • Automatic mode Telemetryport (only with Jeti and PowerBox: Telemetry data are transferred)

The compressor can be powered with a 3S LiPo with 1000mAh.

In order to save weight, the compressor can also be supplied with power from the "larger" turbine battery in turbine models. If there is any potential isolation between the receiver circuit and the turbine (e.g., JetCat, HORNET, etc.) is provided by the potential isolation between the control section and load circuit, which is also realized on the onboard compressor. The voltage of the battery can be monitored via the ECU telemetry. TheVspeak ECU converters for the turbines mentioned are also galvanically isolated, so that potential isolation is guaranteed throughout to exclude interference from the turbine on the receiver circuit. 

Detailed information about VSpeak Auto-Air-fill can be found in the user manuals:
