- Out-of-Stock

Powerful electric fan with controlled ailerons, lift flaps and tail surfaces.
The two-part wing construction made of polystyrene balsa and the carbon-reinforced structural tail surfaces are easily removable.
The good penetration and the profile used make the Challenger a model for recreational flying in thermals and on slopes. Thanks to the profile used and the long surface length, the Challenger is characterized by a calm and stable glide. With the help of efficient flaps, it is possible to achieve a low glide ratio. Flying in thermals is very easy. Landing thanks to the high efficiency of the brakes (when using the throttle) is also very pleasant.
The riser is floating - split, removable for easy transport.
Suitable for those who are looking for a good all-round electric wind turbine.
