LEAF-Talon-01
 
The LEAF Talon is for intermediate or advanced pilots. A high performance glider with responsive pitch control, very stable stall and slow and easy take off characteristics. It has the performance of a trunk tip glider yet the simplicity of a conventional glider.
 
A swing down wing post are standard on each glider. There is black powder baked-on epoxy 4in kingpost and control bars. There are sadddls for longer tube life. The cambered keel spar is 3/4in.
 
The leading edge spars are constructed from 6061-T6 1.75in x .049 aluminium tubing. The keel and crossbar spars are of 6063-T832 15in x .049 tubing. Each spar is drilled, sleeved, bushed, and end capped. The control bar (58in wide) and king post are 1in x .090 6063-T832 aluminium.
 
All rigging wires are 3/32in 7x7 stainless steel clear coated. There are no weak links on the flying wires. All wires are solid swedged with two nico’s. Two aircraft turnbuckles AN155-165S in the top rigging wires are to be tightened after assembly. The wingpost wires are 3/32in 7x7 uncoated stainless steel cable with one AN155-8 (800 lb tested) for tuning.
 
All tangs, three position control bar box, kingpost bracket, wrap around nose plate, and thimbles are stainless steel. Wingnuts, castle nuts, nylocks and bolts are aircraft quality.
 
The sail is precision cut and heavily reinforced with all seams double zig-zag stitched with heavy dacron thread. Prior to sewing, the cloth is overlapped and attached with double sided tape to ensure positive sewing edges. 8in applied sleeves give a cleaner sail. Two battens per side and roach provide improved lift distribution and define washout.
 
A prone harness with knee hangers was optional.
