RE: Big planes
Mike,
Good information already here. You will want to get some help from an experienced pilot with time on large scale planes. The landing will require more power management than smaller planes. It needs to be with some power on as it's very difficult to glide a plane as most trainer and lightly loaded planes are done. You will need to fly the plane in under power. There are pilots who fly in without power however most are very experienced with giant scale planes. The skills aren't difficult just different. In the air they actually are normally easier to fly.
