Since this is the beginner's forum, I'd suggest that beginners not fly alone for a number of reasons.

Safety
You don't learn from others.
You don't have anyone to help you bring back your airplane.
You don't have anyone who might have seen what you did that caused the crash.
You don't have anyone who might have seen where it crashed.
You don't have anyone to figure out why it won't start today.
You don't have anyone to borrow the tools from that you haven't bought yet.
You don't have anyone to borrow a glowplug from when you learn that they don't last forever.
