An Overview of Scratchbuilding

Building From Scratch

This post will outline what scratch-building is, and how to get started with it, (And how NOT to).

Scratch-building is generally defined as constructing a model (a plane, in this case) from its bare parts and without using any kind of kit. Overall, scratch-building a remote-controlled plane doesn’t have to be characterized as you building your own original design. You can download plans other people have made off of the internet (There are thousands) then simply build those plans, or you can make your own design for a scratch-build.   Continue reading An Overview of Scratchbuilding


Hello there,

Today I will be talking about Quadcopters.

Quadcopters, or Quads, for short, are helicopters with four rotors on four sides of the helicopter.

Unlike most helicopters, quadcopters use 2 sets of identical fixed pitched propellers; 2 clockwise and 2 counter-clockwise. These use variation of RPM to control lift and torque. Control of vehicle motion is achieved by altering the rotation rate of one or more rotor discs, thereby changing its torque load and thrust/lift characteristics.

Quads became popular for commercial use in 2010 with the release of the Parrot AR Drone. The AR Drone was designed to be user friendly,  and was most notable for being controlled by and iOS device. (iPhone, iPod Touch, iPad) The AR Drone 2.0 has been released since and boasts much more technology and user friendliness. Learn more about the AR Drone here: DRONE

Today, the technology behind Quads has become very popular and is quickly advancing. Quadcopters have changed human ways of life in many ways. For one, they offer a much more stable platform for hobbyists such as myself to practice with. But lets look at this on a bigger scale.

Imagine an oil company needs to inspect a long pipeline. Normally, they would send out a manned helicopter with a crew of 2-3 to inspect the pipes. Not only does this cost fuel and time, but humans are put at risk. Modern day helicopters are very safe and reliable, but they still can malfunction. Imagine of a single helicopter malfunctioned. The helicopter at best costs about one million dollars. The lives of the crew that were lost in the trouble? Priceless.

Imagine putting a $1,500-$2,000 Quad in the place of this. Sensor equipment would not only be most likely much more accurate, but time, money, and the lives of human beings are all saved. And if the Quad malfunctioned? $1,500 is much less to loose than $1,000,000.

The possibilities to Quads are endless.  Please follow the following links for some great ideas some people have already come up with.

The following one is very important in my opinion. Technology like this could change our world beyond belief.
