The Raptor's tricycle landing gear was fully retractable, and the streamlined pressurized airframe was to be optimized for a fast cruising speed at high altitudes.

The Raptor is to be powered by an Audi 3.0 TDI automotive conversion[9][10] driving a constant-speed pusher propeller and giving a design cruise speed of 300 kn (556 km/h).

The company made a point of favourably comparing their aircraft against the Cirrus SR22, which has been the world's best-selling general aviation airplane every year since 2002.

We will be opening the parts and airframe construction, support and flight training so companies world-wide can compete for your business thereby keeping availability high and prices low.

Also, oil and coolant temperatures were quite high, and climb rate was less than expected, so Muller landed on runway 04 before completing a full circuit.

Muller felt that the issues could be caused by not having raised the landing gear, which increased drag and not having the coolant air intake fully open.

[17][18][19] On 6 August 2021, the aircraft suffered an engine failure and was substantially damaged in the subsequent crash in a corn field Nebraska.

The Raptor NG would have a shorter box wing design, along with twin electric motors driving ducted fans.

[8] The design has been further developed to have a third ducted fan on a vertical axis in the nose, with both main engines able to pivot back 90° to provide upwards thrust and VTOL ability.
