The fuel for single eninge planes costs around $5 a gallon.
it can fly
two planes intersect in one line, or the planes could be parallel. by the way there is no such thing as skew planes...
The angle between two planes when the planes intersect at a point is the acute angle fixed by the normal vectors of the planes.

Mini rc planes are sized in between micro rc planes and standard sized rc planes. There are many models to choose from. A video of a mini rc plane can be found here: http://www.youtube.com/watch?v=0pMnHrb3a20
There are many different types of remote control planes, or "RC planes." Depending on the interest of the person, one could spend anywhere from $150-$10,000.

Better is to order RC planes from website - AIR HOGS as the RC planes provided by them are much realistic and controllable. There is no shop for RC in Brampton......better is to order them through net.
The cheapest micro rc airplane I could find was the Rc universal Biplane Flatout 3D ARF 30.6".Which cost $32 from Great planes or $39 from amazon.This is the cheapest RC plane I could find on the Internet

Electric RC planes are good for beginners because they are easier to fly and maintain. Gas powered RC planes use a nitro-methane based fuel and can be difficult to maintain and to operate.

Electric planes can have many uses to them ranging from just recreationally flying them to races, as well as reenactments of wars. http://www.xenonproject.com/rc-airplanes/electric-planes/
Most rc foam planes have motors or remote controls, so they are not entirely safe for toddlers. These planes are marketed toward an older crowd, so more durable toy planes would be a better fit for such a young child. http://www.rcfoamcrafters.com/
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.
