I have to go along with what flyinrog said. People have learned on low wing planes before without problem but the Super Sportster is a bit too fast for that purpose. It is really more of a second plane. If your local Hobbytown is anything like mine, they have a lot of young people working there who are often more into RC cars than planes. For this reason they don't give the best advice when it comes to planes. The good news is these stores have a good return policy and should let you at least exchange the Super Sportster for a trainer (high wing) style airplane. A couple I know they carry and often have in stock are the LT-40 from Sig Manufacturing and the NexStar from Hobbico. The LT-40 is an ARF like the Super Sportster and should cost around $135.00. The NexStar is also an ARF but comes with more bells and whistles that aren't totally necessary but it is designed to be very simple to set up.

With the LT-40 you will have to purchase a .46 size engine separately while the NexStar comes with one already installed so keep this in mind while making your decision. With your limited funds it may be easier to get a plane first and begin the building process then get the engine later when you have more money saved up.

The instruction manuals for both these planes should tell you everything you need to assemble your plane. Some items you will need for assembly:
30-minute epoxy
razor blade or hobby knife
small screwdrivers

Additional RC equipment you will need:
Radio (this includes the transmitter, a receiver that goes in the plane and four standard size servos that will plug into the receiver and a flight battery to power the equipment in the plane. These items can be purchased new as a set or separatly.
Engine: A ball bearing supported .46 size (Thunder Tiger .46 Pro is generally considered the best bang for the buck) is the best recommended size to get started with. You will also need a glow plug for the engine. Note: if you get the NexStar the engine and glow plug are included with the plane.
Glow Fuel - anywhere from 5 to 15% Nitro should work fine to start off.
Glow plug ignighter - this is basically a battery you connect to the engine to get it started. You take it off before flying - the engine will run on its own at this point.

Some additional advise:
Find a local flying club - there will be someone there willing to help you get started and will provide lots of advice.
As has been previously mentioned, there is often used equipment available that can be much cheaper than starting new. I helped a friend get his nephew started flying last summer on a used LT-40 with engine for only $120.00. All he had to do was find radio equipment, fuel and starting equipment and he was ready to go for relatively cheap.

Good luck!
