                                BLR Tailboom Strake Kit
The BLR Tailboom Strake Kit is the most cost effective, multi-functional, value added, modification ever developed for single rotor helicopters (with enclosed tailbooms). The culmination of seven years wind tunnel and flight test work by NASA / US Army researchers during the late 1980's the design has been optimized for ease of installation and improvements to handling qualities, climb & cruise flight and increase overall yaw control safety margins, all while showing reductions in direct operating costs. This technology is now available in kit form for installation on Bell Models:
204B, 205A-1, 205B (Huey II), 212, AB212,
412, UH-1 and AH-1.

Benefits Include:
Improved Hover-Hold Tasks
Improved Yaw Control Margins
Improved High DA Capability
Reduced Cruise Torque
Reduced Tail Rotor Power Requirements
Reduced Operating Costs (fuel savings)
