Keil Kraft Invader Kit - 40 Inch Free-Flight Towline Glider

Back at long last the original Keil Kraft designs but better than before. Now laser cut parts CAD drawings.


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.

• Laser cut parts
• Re-drawn and re-engineered using CAD
• Robust fully built-up structure
• Iconic twin fin design
• Two towline hooks for different wind levels
• White tissue supplied as a blank canvas for a design of your choice
