Flight Log - 2022-02-19 - David Deavours's Concept 98

Standard dual deployment  I added an eyebolt at the tip of the nosecone to anchor the harness and open some extra space for the main and a tracker.

Flight Date: 2022-02-19
Rocket Name: Concept 98
Flyer's Name: David Deavours
Motors: K535
Expected Altitude: 4,600.00 Feet
Wind Speed: 13.00 mph
Launch Site: Richard Bong Recreation Area
Actual Altitude: 5,547.00 Feet

This is the Mark II version of the rocket. Cold day, in the teens temperature wise, and 13mps winds. Sunny but cold.   Kept the AV Bay warm with a hand warmer until it was time to launch.  The rocket coned significantly off the rail and I originally thought it had struck the rail and destabilized for the first bit of the flight. However, upon recovery I noticed a notch in the nozzle of the K535 single-use motor which could account for the coning and veering off in one direction.  

Recovery was 3,500' down-range just a few feet inside a field.  Long, 2,500' walk from the road in the snow and briar patches.
