The 136 is a slightly smaller size of the T2C optimized for a
range of pilot body weight centered on 150 lbs (68 kg). The 136 features a new
size control bar, halfway between that of the T2C 144 and the Sport 2 135. When
configured with the lightest weight options, (Litestream downtubes and UVPT
panel #1), the 136 weighs in at only 68 lbs. We have completed all developmental
flight tests and all vehicle tests (positive and negative loads, and pitching
moment tests) on the glider and we are now accepting orders. Estimated
production time is 14 weeks.
