The Panther S Specifications follow. We consider any Short wing Panther Aircraft an S regardless of engine.
WITHOUT the elevator mass balance weight you must use the Panther LS “VNE” (200 mph TAS).
WITH the elevator Balance weight use the following Panther S Speeds and limits. Due to shorter wing, and resulting higher wing loading the Panther S cannot meet the “LSA” rule’s Vs (stall speed).
