Tier 1 Engineering conducted the first flight of an all-electric Robinson R44 using the MagniX 350 electric propulsion unit (EPU) earlier this month. The three-minute flight took place June 4 at the Los Alamitos Army Airfield in Southern California in a little over six months since the start-up selected the MagniX motor in December 2021.

The integration of the MagniX EPU has been handled by Tier 1, which has developed its own battery system. In the first instance, the electric version of the four-seat helicopter is being developed for Lung Biotechnology PBC, a biotech company that is focused on alleviating the shortage of transplantable human organs.
