Tall Paul, you are right, the batteries can be recharged between flights, just not during one attempt (i.e. a failed launch, cannot go and top-off the batteries before next launch but if failed flight attempt, can go top off batteries while waiting turn in line)
Aw shucks! That takes all the fun out of it! ! ! !
I actually did some power to weight calculations that I didn't post just for myself. And with a 12 volt 2200 mah pack it would be possible to do all three missions from one charge but only with some thoughtful planning on which tasks to use how much power and how fast you'd fly the load bearing missions. I thought that between the requirement for the hand launch and careful doling out of the power that this would make for a highly challenging event. Now I find that I read the rules wrong and there will be more than enough power on board to do all the missions easily. So we're back to the guy doing the javelin launch and the pilot's ability to correct for any faults in time being the only real limit to plane and load.
You want to get that guy chosen and onto a high quality steroid diet pronto to be up to snuff for the final meet.....
