Maybe someone can help me. My OS 1.08 dies after about 5 - 8 minutes of strong running while in the air. I have checked all lines, tank position, and any other thing I could do but to no avail. I am thinking about leaving the glow plug lit for the entire flight using the onboard system. Would that destroy the plug or dramatically shorten its life? I'm about to give up on this thing and change engines or go to electric or something! Any help would be very much appreciated. Fred [email protected] Thanks!
