Robinson Helicopter Company is offering an FAA-certified slimline auxiliary fuel tank for its R66 turbine helicopter.

The tank holds 23.2 gallons (88 litres), roughly half the fuel of the company's larger auxiliary fuel tank, adds approximately one hour to helicopter endurance and extends its range by as much as 100 nm. It mounts on a fibreglass tray that is installed in the aircraft's baggage compartment, occupies one-third of the space and leaves room for up to 200 lbs of baggage. Both tank and tray can be removed when not in use.

The tank weighs 29 lbs when empty and 189 lbs when full. It includes a crash-resistant fuel bladder that fits in an aluminium and fibreglass enclosure with an internal fuel pump that transfers fuel to the helicopter's main tank at approximately 40 gallons per hour. Controls are located in the upper instrument console and feature an on/off switch, a no flow annunciator light and a fuel quantity button.

The slimline auxiliary fuel tank is available on all R66 helicopters ordered now until 31 December at a reduced price of $14,500.00 USD.
