J-3 Cub 25 ARF

E-flite EFL4000 Airplane (Discontinued)
This item is discontinued but parts are still available in the Parts List below.

This is the only 25-size Cub with scale ailerons. Quality balsa and light plywood construction make for a sturdy, lightweight airframe that handles incredibly well in most flying situations. The firewall is set up for use with an outrunner motor, such as E-flite’s Power 25, making a perfect power match for the airframe. Optional floats add a new dimension to the scale flying experience, and the one-piece wing allows for easy transportation to and from virtually any flying field, pond or lake.



• Outstanding scale detail, including the factory-painted fiberglass cowl with molded engine detail
• Scale aileron design sets the E-flite® J-3 Cub apart from other 25-size electric Cubs on the market
• E-flite's optional 25-size floats are easy to assemble and attach to the J-3 Cub, and offer thrilling performance during water taxi and takeoff
• Built-in float mounts
• Removable one-piece wing for fast transition to the flying field
• Factory-painted landing gear with authentic Cub wheel caps
• Quality balsa and light plywood construction, and genuine UltraCote® covering
• Outrunner-ready firewall—perfect match for E-flite’s Power 25 Outrunner, 870Kv
• Flies great with Li-Po (THP42003S2PPL) or Ni-MH (EFLB4010) packs
