RE: Getting started, on a budget, with a size limit
Maybe look for some used equipment???? Or take your money and buy a simulator. many have learned to fly using a simulator. This will do tho things for you. Teach you to fly and let you find out if you REALLY like the hobby. I'm thinking you already like the hobby!!
Don't get in too big a rush. Take your time and find exactly what you need. Maybe take the time to look up an experienced pilot (although your buddy sounds somewhat experienced) and drive there if you need to and have a bull session with that person. I think that would be time well spent. Also a local hobby shop could also be a good source of info. Do your research first.
Good Luck on your quest!!!!
