Starflight TX1000

starf-tx1000


Similar to the Tristar except with a conventional three-axis aerodynamic control system, nosewheel has suspension and a nosewheel brake. The prototype of the TX 1000 had its first public showing at Sun'n'Fun in March 1983 at Lakeland, Florida. De-scribed by Dick Turner as a development of the Tristar, this newcomer uses the same wing with 5 degrees of dihedral and double skin over 30% of the chord. However, it uses a different engine, a Rotax unit.

It also has a considerably reinforced structure, the leading edge spars being 2 inch (51 mm) diameter, and the compression tubes and trailing edge spars 1.5 inch (38mm). There are other differences from the Tristar too: the horizontal tail is stiffened in flight by V-struts and on the ground by stainless steel cables instead of just the cables of its predecessor. On this model a braked steerable nosewheel is standard. There is a black epoxy coating on all exposed airframe parts, bonded to the tubing and baked to a glass finish.

The TX 1000 was sold as a kit requiring 40 h for assembly for $5195 in 1983, options being electric start and a hand-deployed parachute.
