Aerobatics is both physically and mentally extremely demanding. It can be competitive, frustrating and is extremely hard to master.
On the other hand, it is hugely rewarding, exciting to fly and has a very close community with competitors often helping their opponents overcome issues that might keep them on the ground. It will build your capacity and understanding of the principles of flight, and needn’t cost you an arm and a leg (although that option is always available!)
Above all flying aerobatics is fun, and something every PPL holder should at least consider.
