I would also HIGHLY recommend the 62" Osiris.  The kit is excellent, it goes together quickly and flies extremely well. We're flying it on 5S packs, but there is a motor set up for 6S, and it's probably easier on the batteries.  TON'S of power on the 5S setup but the draw is high and you're limited to about 6min on a 5000 pack. The 6s also has a ton of power with lower draw and longer flight times.
