Go find a club near you. Trust me, it will be the funnest part of the hobby....and it will save you allot of money in the end. Clubs are filled with experienced pilots, and there is something about this hobby that attracts helpful friendly people. Somebody will probably have a trainer that they will buddy box you on and trust me that trainer will get your nerves going so much that you'll think it's a P-51. After that you'll feel just fine about flying your own high wing trainer around for a while. Here's my advice. Don't skimp on gear your first time around. You'll end up spending more money in the end when you want to advance in the hobby. Get a good radio the first time around. I made the mistake of getting a four channel JR that I replaced within a year. For a little more money I could have just bought the 7 channel that I still use today. I wouldn't recommend anything less than 7 channels.....the more the better. Also, buy a motor, ESC, Battery, Servos....etc. that can transfer to the mustang later. When you're ready to put the trainer away and fly the mustang, you'll already have the gear you need to put in it (assuming it survives the training process). good luck and have fun.

WARNING! if you choose to build that P-51 and fly it.....it will most definitely crash. and you will be so heart broken you'll probably give up the hobby.
