Guys Something a pal asked me about last week got me thinking about a project - I wonder what your thoughts would be on it. There is a disused 20-mile canal that runs from a lake near where I live and I'd be interested in filming the whole length of it. The country footage could then be sped up to make a shorter edit, with slower sections around the lock gates. There is a towpath that runs the length of the canal alongside, so I could possibly be a passenger on a motorbike or quad to control the craft while traveling along slightly behind it. I realise that I would have to stop to change batteries and therefore would have to edit the clips together - but that shouldn't be an issue. It could be done over a number of days if needs be. However, what would be the potential pitfalls in doing something like this? I assume I'd have to set the maximum distance range to whatever a full battery's worth of distance would be, but what about the RTH function when the craft detects that there won't be enough juice to return to the original home point. I could always pause and reset the home point and then continue? Any other issues that I have glaringly not thought about?
