Sizes are compact. Example flying toys list dimensions around 4.5" H × 2" W × 6.5" D. Brick-built microfighters or mini-builds often assemble to about 1" high and roughly 4.5" long by 3" wide.
Typical features include a minifigure-sized cockpit, one or more tiny stud shooters, and at least one included figure or droid-head element for play and display.
Review summaries commonly praise solid, well-built construction and note that microfighter-style sets are quick and easy to assemble.
They typically use a coaxial rotor for stable hovering, infrared motion sensors to detect and avoid obstacles, respond to a hand held beneath them to hover, and include USB charging; some listings also note spare rotors and an IR remote for shutdown or recovery.
