super slim, light and very small - espacially for F5J class
This set is designed for F5J gliders up to about 3.6 m and 1,6 kg takeoff weight and very slim fuselage. The fuselage of the model should offer enough space for the internal rotor 400-F5J/light with 4.4: 1 gear. There are about 26 mm body diameter inside needed. Due to its speed of 3.000 rev / min / V in conjunction with the 4.4: 1 gear makes it perfect for propellers up to 17 inches. For reasons of space or weight , a small 2S-3S LiPo is used.
With an Aeronaut Cam Carbon 15x8 the 400-F5J/light generated about 270 watts.
As a battery, we recommend an extremely slim LiPo to 1.800mah. With this set, it goes very quickly to the limits of vision and the model is super easy to take even the smallest thermals.
The max. engine running time is based on the F5J regulations and should not be more then 30sec.
