First thing I would do is buy the Great Planes Rel Flight Simulator, If you have PC..

It will give you a good start on the orientation and getting use to the sticks, If you crash on here just hit the space bar and you have a new plane, soone told me that the software will pay for itself many times over.

It is very realistic and fun, I't s basically how I learned.

I started with the Hanger 9 Alpha Trainer RTF - Readt to Fly Everything is installed and is done for you, Just fuel her up and go. I paid $275

Flys great and is easy to land. But it is gas not electric.

Sounds like a good thing your doing, Your boys will remeber their times spent fly with dad forever.

Good Luck!
