You probably can fly them. The big trick is landing them. Things happen faster. You have less time to react. Your muscle memory training isn't fast enough yet to allow you to correct things in an instinctive way. You may react wrong and there may not be time to realize it and correct it. Its all about the landing. However, experienced pilots will find advanced planes EASIER to land. They just slide right down the pike and land without a great deal of correction for wind or gusts. They are actually less work to land, if your brain can keep up.
