The problem of components not conforming to their claimed specification is one that must challenge engineers in all fields, including it seems, that of multi-rotors and remote controlled aircraft. A ...

Controllable pitch propellers adjust blade angle instead of engine speed, letting ships change thrust, direction, and handling instantly. This explains the physics, advantages, and tradeoffs compared ...

Vertical Aerospace’s initial VX4 prototype was written off after the failure of a propeller blade due to a manufacturing fault which led to a loss of thrust from two of the aircraft’s remaining ...

When you picture a propeller-driven aircraft, you probably imagine a single engine plane with the propeller spinning at the front. There's a good reason for that, as the front-facing design has proven ...
