Ummm..... so what do you really want to do?
The radios and components are different between marine and air and from your questions you'll need help with whichever one you choose. I can't remember the name of the local boat club but if you want to go air I suggest you spend some time out at the field asking questions. We also have trainer pilots but I don't think the club trainer exists anymore. The field is in Saratoga Springs next to the Jordan river and is a really nice facitily other than there being water on three sides to complicate dead sticks but no field is perfect unless you've lots of money to join a private facility.
