As opposed to coax, fixed pitch have only one main blade (like most helis). But this main blade does not vary the pitch / angle of attack / inclination position. Hence they need hefty throttle RPM to keep'em aloft. They can be with a flybar at 45° (docile) or at 90° (a bit more aggressive). Or can be flybarless, which have no flybar, requires different gyro and a rather good pilot to get it off the ground. Since you can not vary the pitch to stick it to the ground on spool up, they do suffer from tip-over-on-spool up.
Some say skip fixed pitch as it only teaches bad habits of throttle chopping for descent, I belong to that school of thought.
