Hahaha...Makes me start to wonder how much power i have left in my flight pack..As i've only been flying for about 6-7 weeks and on a day at the feild ill use up to 1.5 litres of fuel in my kyosho calmato with an os 46 fx and i only have a 600mah pack that comes standard with the JR radios... Might have to get a volt checker....
