Thanks again...

Yeah that is really my main concern right now. Our back straight away is around 100 feet, just to give you a idea of the size.

Last night, I ran my Turnigy trying to hit the cutoff, to see how long it will run, after 30 mins ( on the dot ) I brought it in and took a look. I was concerned the cut-off had been disabled, it was not, and when i threw it on the charger it was at 7.6v.

I feel much better about making the length in the mains now.

Thanks for all the input guys.
