Has there been a study of how much flying time can be gained by reducing the weight of the P3P? I understand that information might be theoretical because it seems unlikely that the weight of the flying bird could be reduced, for instance, by a pound (.45kg).

However, assume for a minute that it would be possible to reduce the weight by a pound. The battery, motors and 'flyability' would remain virtually the same. The strength of the structure would also remain the same. In effect, the bird remains the same but weighs a pound less. How much longer could it stay aloft?

This "weight loss" is achievable, in fact I have already done it! To surprise you further I have also "removed" almost 2lbs. (.9kg) of weight and my P3P has the same qualities of a freshly unboxed aircraft.

So, my question is: How much longer, if any longer, can I expect the bird to fly? My guess is that any increase will not be linear and not be directly proportional to weight loss. I suspect that there is a time factor involved in the discharge rate and once the battery is being depleted the rate of discharge may not be solely related to work.

FWIW I am looking to get 45 minutes of flight time under particular conditions. Doable? We'll see. If you've been interested enough to read this far, send me a message and I'll tell you how I reduced the weight. Anyone could do it. In fact someone has probably already done it, I just don't know about it.

Because it was a lot cheaper than a Sikorsky, that's why!
