Yesterday morning I took my younger son out for some 1-on-1 time. We launched his four B-capable rockets at the local middle school. Finally got a Q-Jet B6W to light! Used a tiny sliver of Blue Thunder to augment the igniter. Still burned one with no ignition that seemed to be inserted fully, though. I'm not buying more 18mm White Lightning Q-Jets, but it was satisfying to finally get a couple to light and launch. They do give a better show than the Estes B6s.
