thats the smartest quote Ive heard in a long time. I really appreciate all of the input... It does seem to be rare that battery failure is the cause of most crashes but, it sure seems to be cheap insurance to double up. If it was just a plane we could pluck off the shelf and fly it may be different but, most like me (I think) pour a lot of themselves into making a plane they are proud of and to see it dig a hole for a lack of 25.00 and a tad more effort is just a shame. Thanks again all... this has to be one of the best web communities on the net.
