any way to do it? can the P2V+ carry it? is there a parallel harness sold anywhere? im thinking the biggest factor in flight limits is the extra weight of a 2nd battery. im sure the long range junkies like DBS already know of this answer. im NOT looking for any "performance hindrances" answers since, well, its a flying camera not a tour de france competitor. can it do it or not. is the harness sold or not. thx.
