  • DESCRIPTION
  •  In short what we have here is a 750 gram(AUW), 2.5 meter electric with a 4 servo wing.

    The overall construction is very similar to a DLG but more robust.  The matt surface finish on the wings and tails is quite good and to be honest we're not sure how they do it.

    The Geronimo's wing profiles are derived from the same AG foil sections that Mark Drela designed and used for his Supra. The AG foils provide exceptional performance in thermals and are very capable of piercing through sink. The wing features a slight polyhedral as well as independent ailerons and flaps allowing full wing, camber, reflex, crow etc.

    If you would like more information you can study this build thread on RC Groups. While the thread is for the 2m version the build is nearly identical. Start with post 124.
