GWS flight simulator cable with USB interface

  • Price: $13 + S&H
  • Vendor: Grand Wing System U.S.A. Inc., 138 S. Brent Cir., City of Industry, CA 91789; Tel.: (909) 594-4979; Web: www.gwsus.com

RC flight simulators help beginners learn to fly by simulating “flying by remote control,” where the pilot is on the ground viewing the aircraft. With time and practice, control inputs become instinctual.

This USB flight-simulator cable module is designed for children and beginners. Link the flexible flat cable between your computer and RC transmitter and run the FMS flight simulator software to practice and improve skills to prevent crashes. The module is not supplied with the simulator software; download FMS from http://n.ethz.ch/student/mmoeller/fms/down.html. Cable modules are available to fit most popular transmitters and are available at local dealers.

Grip Pins (50-count box)

  • Price: $5.89 + S&H
  • Vendor: Midwest Products Co., Inc., Box 564, Hobart, IN 46342; Tel.: (800) 348-3497; Web: www.midwestproducts.com

Grip Pins are an improved alternative to straight pins, push pins, or T-pins, offering a faster, more accurate assembly process for modelers, crafters, and students. They feature a longer, thinner shaft, a wider shoulder, and a tapered barrel body for easier gripping. The wider shoulder reduces cross-pinning, and the extra-long stainless shaft allows stacked assemblies. Grip Pins leave smaller pinholes, are easy to see to reduce loss, and the box provides convenient storage.
