I had my second flameout with my Reaction54 /p-70 yesterday, and made it back to the field with no issues. I traced it the fact the glow plug came loose and fell out so it was obvious when we got to the plane and saw it hanging. Just thought I'd pass this on as guys with bypass planes may not look first for a loose plug when the engine quits. Put the plug back in and had 3 more flights with no issues.
