There are many different types of RC airplanes that are available for purchase. The cost of one varies depending on what type you want and the size of it.
An RC plane simulator would run you about $40.00 according to this site: http://www.trendtimes.com/rc-helicopter-flight-simulator.html You might want to do a search for yourself to see what you come up with.
The price range for an electric remote control plane would vary based on the type of plane you want. A basic one would cost much less than one with more expensive material or a large one.
The prices of RC transmitters vary. They can cost from as little as $150 up to thousands of dollars. RC transmitters can be purchased in stores or online. Here is a website I found: http://www.rcplanet.com/JR_Radio_Systems_s/2086.htm
how much is an RC XD
If it is an electric RC plane then all you will need to pay for is the plane and if you plan on crashing a lot some spare propellers if it is an RTF or ready to fly version. If it is an ARF or almost ready to fly you will have to buy a motor too.
I would say between 75-110 dollars.
The cost of micro remote control (rc) boats may vary depending on the model of the boat. Some range from $40.00 to over a hundred dollars. They are small and therefore can be utilized anywhere.
A mini RC plane can cost as little as $30 to over $1000. The price depends on the level of detail you desire, scale, if you wish to build from a model kit, and the material of the plane. Foam planes with simple stickers are on the lower end of the price spectrum, while highly detailed larger scale models are more expensive.
Both RC plane are awsome because they are both planes.
RC warships are small remote controlled boats which oftentimes are built to fire small BBs at other RC warships causing them to become damaged and sink. RC warships typically run about 30 dollars a piece depending on their capabilities.
Anywhere from $5 to $500. It depends on the size of the plane. I get all my motors from hobbyking.com
