The worst FSI power-prang I ever had was in a Star Gazer I flew in the 70’s. I used an E5-0 to E5–6. I didn’t know much about motor selection back then but I learned quickly that these weren’t on the recommended motor selection list for a reason. One nice long burn arcing cruise missile flight into the center of a parking lot on asphalt really far away from where I launched it.
