I would not suggest the Cessna as a trainer. MOST scale models do not make good trainers.

Even though the EasyStar is back ordered (Tower says the KIT is in stock, but the RTF is due in in mid August) I would get that.

The best suggestion I can make though, is to get an instructor and see what the instructor suggests for a trainer. An instructor can not only help keep you from damaging your plane while learning, they will usually make sure you do not learn any bad habits. Clubs furnish instructors at no charge.

If you want to do this without an instructor, get the EasyStar. The EasyStar will handle wind up to about 10 mph with little or no problems, while a Slow Stick (also an excellent trainer ) has difficulty with wind much over 3 - 4 mph. While the Slow Stick can be flow in a baseball field size area, the EasyStar does require an area the size of a football field. In either case, the larger the area you have to fly in, the better off yo will be.

Hope this is of some help.
