Notes
- The Apprentice STS is E-flite's 1.5 m high-wing trainer (EFL3700 RTF / EFL3750 BNF Basic). The file models only the wingspan × length plan-view envelope.
- Height, wing area and prop size are not published on the listing used; the figures come from a retailer copy of Horizon Hobby's spec table, so the entry is marked secondary.
- True size, no printing tolerance added. Only published numbers are used; anything not published is said so.
- Secondary source: the numbers come from a retailer or magazine copy of the maker's specification.
