Welcome to RCU. Great place with a lot of good people, all willing to give advice and opinions.

The Cessna isn't a terrific trainer, but if you can find an instructor willing to try, you may do okay with it.

Here's the AMA's website. They have a "Club Locater" page, just plug in your state or your Zip Code to find one close by. http://www.modelair.org/

You'll need AMA membership for most clubs (for the liability insurance), plus club membership. Total of $100 or so, plus field support equipment, like a glow igniter with charger, fuel pump, 10% nitro fuel and extra fuel line (at least 3 feet), a 12 volt starter with 12 volt battery makes engine starting much easier, and extra glow plug and a couple extra props (10 X 6 or 11 X 5). Another $80 to $100.

Try Tower Hobbies (or your local hobby shop) for these items. http://www.towerhobbies.com/

Good luck,
Dennis-
