Eli F3-RES from Zellair


The model Eli is a current construction of Julius Valastiak from Slovakia and has won in 2020 all 3 RES competitions held there!
The construction is designed for dynamic flying, the wings are prepared for an additional ballasting of about 100g.
The model can be built as a glider or electric version and convinces with a contemporary design and the excellent workmanship or high-quality components.
The laser cut and CNC machined kit features a simple and robust construction. The fuselage consists of a front fuselage section in classic balsa/plywood construction and a high-quality handmade conical CFRP fuselage tube.

The wing is 2-piece, the superstructure is in the classic and proven tubular spar construction method. High-quality hand-wound CFRP tubes are included. With the large 2-piece landing flaps, nearly vertical descents are possible without the need for a ride.

The tailplane, milled from lightweight balsa, is removable.

Only selected balsa and plywood optimized for weight are used for the kit.

Gluing of all components with commercially available systems such as superglue, white glue or 5-min epoxy is very easy and machining of the materials is trouble-free.

The design allows the use of commercially available and easily available components such as the Eneloop lite 550mAh battery pack as well as Hepf H47 or EMAX ES09D and ES9051 servos.
