RE: *1800 mAH Battery In Cold Storage*
If you say your changing glow plugs every gallon of fuel there is definately something wrong with your procedures or your thinking. I fly nothing but 4 strokes and use OS F plugs. That means I would spend $10.00 for every $20.00 worth of fuel [X(]. My glow plugs last at least 100 flights and in some cases 150 flights. Never lost a plane in 25 years due to bad glow plugs or bad batteries. Just stupidity
