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 ...

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 ...
