The Arcus-J is a Schempp-Hirth Arcus M sailplane with a retractable PBS TJ-100 jet engine. As for the BonusJet, this conversion into a motor-glider was carried out by Desert Aerospace. Bob carlton made the first flight on September 29, 2016.
A memorable flight
On October 14, 2016, an interesting flight was made : Launching from Inyokern (CA) at sunrise, Dennis Tito (Arcus-J owner) and designer/copilot Bob Carlton powered up to 8,000 MSL and found the wave. Over eight hours and 1,175 km later, they landed after the first significant long soaring flight in a jet-powered sailplane. This first ‘real’ long soaring flight demonstrated the jet sailplane’s ability to optimize soaring conditions.
As Bob wrote after this flight : " It confirms the advantages of a simple, reliable, low drag (~38:1 with engine extended) engine system that can be started at high altitude after hours of cold-soaking, and run fast enough to push through the winds ".
