RE: Hangar 9 Funtana 40
I have a Funtana 40 with the leading edge of the wing modified to give much greater airfoil. The new Funtana 90 is modified this way. I set my CG per the plan and then fly a 45 degree upline inverted and if it arcs toward the ground add weight to tail till it continues on a straght line. I have one ounce on tail. Plane flies perfect on 45 degree upline either side up. The Saito 91 engine is the engine of choice for me with the APC 15X4W prop. If you desire I can send picture of the leading edge modification that makes these planes fly great without tip stalling. I understand Horizon will probably be modifying the 40 in the near future like the 90. My friend Wayne Mayer modified mine for me as it was his design. Current leading edge is a piece of 1/8th thick balsa rounded off. Easy fix to add one half inch thick piece on top of new 1/8th inch piece and fashion a new air foil that works.
