Comments The third flight of the Hytest-1 rocket was launched in higher winds than the previous launch, causing the rocket to weathercock considerably. Coupled with the fact that the rocket has 4 large fins, this meant the rocket reached a considerably lower apogee altitude. Again, the 2-stage recovery system had been dispensed in favour of a single stage deployment system.
The R-DAS igniter jumpers were shorted out on this flight, to disable the output current limiters. Previously, the main channel had not fired (with DaveyFire igniters), so it was felt that this method should be tried. It worked perfectly, and both igniters in the SafeEject ejection canisters fired.
