J3 Cub Overview

This is the only 25-size Cub with scale ailerons. Quality balsa and light ply construction make for a sturdy, lightweight airframe that handles incredibly well in most any flying situation. 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.

J-3 Cub 25 ARF Bulletins

Important Note

We have found, during continued flight testing, the possibility of a rx/servo current overload to the BEC in the speed control, causing the motor and radio to shut down in flight. This has typically happened on extreme high temperature days with continuous extreme flight control inputs. Most speed controls on the market today are designed for use with 4 sub-micro servos with relatively low current draw, like the E-flite S75. The newer sub-micro digital servos, as well as most micro and mini servos, have a higher current draw and can cause a BEC to shut down due to high temperatures. In order to provide the most reliable product, E-flite recommends the use of a separate BEC (like the Ultimate BEC), or receiver pack and switch using the following items to ensure trouble-free operation:

(1) 720mAh Ni-MH 4.8V receiver battery

(2) Standard Switch

Use these items to power the receiver and servos after disabling the BEC on the ESC (by following the instructions included with the ESC).

E-flite does NOT recommend using the speed controller’s BEC in the applications described above.
