Keil Kraft Invader Balsa Glider Model Kit Wingspan = 1016mm (40\") The Invader was always a popular model in the Keil Kraft glider range thanks to the distinctive twin fin tail. The Invader is a simple to build towline glider that was originally designed by Albert E. Hatfull, and has since been redesigned in CAD. The polyhedral wing and dihedral tailplane offer superb stability while the sturdy stick built fuselage is extremely robust for those less than perfect landings. The two tow hooks also offer the pilot different launching options depending on the wind speed on the day.
