Its successor, the MacCready Gossamer Albatross can fly as slow as 9.23 miles per hour (14.85 km/h). [1] It has a maximum speed of 18 miles per hour (29 km/h). [2] The Ruppert Archaeopteryx has a certified stall speed of 30–39 kilometres per hour (19–24 mph). [3] The Vought XF5U can fly as slow as 32 kilometres per hour (20 mph). [4]
A radio-controlled aircraft (often called RC aircraft or RC plane) is a small flying machine that is radio controlled by an operator on the ground using a hand-held radio transmitter. The transmitter continuously communicates with a receiver within the craft that sends signals to servomechanisms (servos) which move the control surfaces based on ...
A hardpoint is an attachment location on a structural frame designed to transfer force and carry an external or internal load.The term is usually used to refer to the mounting points (more formally known as a weapon station or station) on the airframe of military aircraft that carry weapons (e.g. gun pods and rocket pods), ordnances (bombs and missiles) and support equipments (e.g. flares and ...
The document used to prepare a single test flight for an aircraft is known as a Test Card. This will consist of a description of the Test Points to be flown. The flight test engineer will try to fly similar Test Points from all test plans on the same flights, where practical.
An RC flight simulator is a computer program that allows pilots of radio-controlled aircraft to practice on a computer, without the risk and expense of damaging a real model. Besides the obvious use of training beginners, they are also used for practising new aerobatics, evaluating a model before buying it, and to allow flight practice when ...
In a stall turn the plane goes upward, decelerates, yaws 180° under stall, and comes down nearly the same path it goes up, as if it gets hammered on the head. To perform a stall turn; From level flight input up elevator and reduce power until the aircraft stalls. The angle, speed, and abruptness at which stall occurs depends on the aircraft.

The Cooper-Harper Handling Qualities Rating Scale [1] (HQRS), sometimes Cooper-Harper Rating Scale (CHRS), is a pilot rating scale, a set of criteria used by test pilots and flight test engineers to evaluate the handling qualities of aircraft while performing a task during a flight test. The scale ranges from 1 to 10, with 1 indicating the best ...
