Ever since Aerotech came out with the H13ST over a year ago I've wanted to scratch build a model that could take advantage of it. I played with a design for over a year to get to a point where I was ready to build it. I tend to design models that can meet multiple objectives so that I can fly it multiple times to try to meet different design criteria. My goals for this one were:
Below is the side view from Rocksim.
- Ability to fly on long burn engines safely in low to moderate winds (< 7MPH). Specifically, the H13ST and also the G12ST and the Apogee F10 (in lower winds, <3 MPH).
- Ability to fly on F & G motors on smaller fields.
- Ability to fly on high thrust motors when the winds are so friendly, up to an H195NT.
- Ability to fly at or above Mach 1 on high thrust motors (stretch goal).
- Large enough airframe to allow TTW fins to handle the high thrust motor options (over 40 G's on an H250G).
- Include a nose cone E-bay with a deployment altimeter for apogee deployment and a GPS tracker, since this sucker will go WAY out of sight on either the H13ST or the H195NT.
- Be able to come down on a parachute small enough that I can use a JLCR to keep it from drifting for miles. No room for a drogue.
