HeliCommand Ultra-acoustic Suppression Hood

For protection of the X-series' sensor units from ultrasonic noise emitted by turbines.
The HC-X-series is already prepared for the use in turbine helicopter by an integrated ultra-acoustic absorbing foam. Depending on individual constructions and kind of scale fuselage, this protection may not be sufficient.
To cover all eventualities, the use of this suppression hood is mandatory when using the systems in turbine powered helicopters.
