RE: new to flying
These guys are right eaglesfn68, you need to start out with a trainer of some sort and get with an instructor. It sucks to have to wait if you are really wanting to fly aerobatics, but it is honestly essential to start with the basics and get grounded in the fundamentals to ensure your success. The planes you are wanting are definitely a lot of fun, but it will take time to get to the point that you are ready for it. People who have experience can make flying 3D/4D planes look deceptively easy. They are easy to fly ONCE YOU HAVE MASTERED basic flying, but actually hovering and flying in high alpha takes a lot of hard work and TIME. Whether you need to wait until your 2nd, 3rd or 4th planes depends on your skill and age frankly. Some guys can easily move from a trainer right into a basic 3D plane like a profile or a U Can Do as a second plane. Some need to make a gradual transition. The trick is to be honest with yourself and do not bite off more than you are absolutely certain you can handle. I would say you need to get that trainer, let an instructor teach you how to fly it correctly, and then fly the crap out of it. Fly it until you can unmercifully wring it out and perform the basic aerobatic maneuvers with total control and you have gotten to the point that you can get out of any situation without thinking about it.
Learning to fly the trainer proficiently should keep you busy for 3-6 months if you are flying at least a couple of days a week and you have good hand eye coordination and depth perception, if not it could take longer.
Once you get to that point, you should be able to make your own decision as to what you can handle.
