Details.
The iLevil AP moves a trim tab, not the control surface itself. The tab does the flying: a small servo deflects it, the airflow does the rest, and the aircraft follows — which is how a light-sport or Experimental aircraft gets an autopilot without heavy servos, long linkages or a certified installation.
Sized by cruise speed
The slower the aircraft, the larger the tab that is needed to move the surface. The Large kit is for aircraft cruising at 80 to 120 kt — most light-sport and many Experimental aircraft. Medium covers 120 to 140, Small 140 to 180 and Jumbo 50 to 80 — choose by the speed you actually cruise at, not the speed on the brochure.
What is in the kit
The servo and the trim tab, 12 inches long with a 2 inch moving section, at 150 g for the kit. Riveted, screwed or bonded to the surface with strong double-sided adhesive, as your airframe allows.
