SNS3Guppy - thanks for reminding why I so rarely visit Pprune - home of the 500-posts-a-year finger-waggers
If you took the time to actually read the post, you would realise that Sandbagsteve was simply passing on his experience regarding NiMh battery life issues; derived I surmise, from working as a photographer.
He was doing nothing more than passing on information which he considered may be of interest or use to fellow pilots. In that assumption, he was correct as far as I am concerned - thanks for the info Sandbag'.
But thank you for reminding me why I don't waste my time here very often.
