The Tier 1 Robinson R44 was built under contract from Lung Biotechnology PBC as an Electrically-Powered Semi-Autonomous Rotorcraft for Organ Delivery (EPSAROD). The idea is that the Tier 1 will be able to quickly transport manufactured organs to those that need them at nearby hospitals. The modification of the R44 took six months with Tier 1’s nine-person team. The aircraft utilizes lithium-polymer batteries for power, which were provided by American company Brammo.
The first flight of the aircraft was on September 21, 2016, where it flew for five minutes and still had 80% of its reserve power. With better batteries, the Tier 1 Robinson R44 will be expected to fly for 150 minutes and lift a payload of 600 lbs (272 kg).
