We provide harnesses using Nylon, Spectra, or Kevlar. A harness is used as a direct multi-point connection to the airframe. Generally, you use either a Y harness or several straight harnesses to make a multi-point connection. For UAS, a 3 or 4 point connection may be needed to keep it level.

Material advantages of Kevlar include:

Kevlar is heat resistant. Use Kevlar near the ejection charge where it's needed. Most rockets require a Kevlar harness.
Spectra has even more strength per weight than Kevlar but is not heat resistant. However, it is very lightweight and tangle-resistant, which is ideal for UAS.
Nylon is lower in cost and allows some stretch to lessen the opening shock.

Size your harness to allow for 6 inches to 12 inches to hang out of the airframe, making connection to the shock cord easy. On UAS, allow a length that provides a center point well above the airframe.

All our harnesses feature:

Pre-sewn loops
Stitching with Kevlar thread
A single Y harness for a two point connection, several for 4 point connections
Several straight harnesses for 3 point connections
