<DIV>I get several hundred flights typically. Two keys: no lean runs, and an adaptive glow starter like the Radio South units. One lean run can ruin a plug, and the adaptive starter applies more current depending on how much fuel is on the plug. I get them relatively cheap from Central Hobbies.</DIV></DIV>
