Electrics - Cost is not as bad as it appears

[Daniel Dupont]

Don't get me wrong, if the price come down for the battery I will give it a 
try for sure.  But I would hate to have only one plane on 
Electric.....since I would still have to carry all that gear in case I need 
the fuel plane...:)

But my understanding at this point says...you cannot recharge at the field 
since the battery will already warn from the discharge cycle and I like to 
fly at least 6 flights, often more....

I always a spare fully charge pack for my radio, good for about 12 flights 
altogether.

I carry all king of spare parts including complete a engine / spinner 
/starter / glow driver / ect.ect......since I often fly well away from home 
about 100 miles, and I fly there because since it the most concentrated 
Pattern in the Atlantic Canada.
