Hoping the glider pros here can diagnose why my scratch-built slide pod did a 360° spiral on the way up? It wasn't a tight spiral, but more like a quick loop before settling into a normal glide at ejection.
Confirmed that nothing is misaligned (although I purposely made one wing 1/8" lower to get the glider to circle) and there was no rod-whip, it only did the loop about midway up.
