Blaze by HobbyKing: R2 Touring Car and DFR 1/10 Scale Drift Chassis

Last week HobbyKing announced the release of two new Blaze chassis cars. One is the Blaze R2 1/10 Scale Touring Car, the other is the Blaze DFR 1/10 Scale Drift Chassis. Both of these models share a number of similarities, as they are both based on the very popular and successful MTS T2.

Custom Workbench Build #2

Following on from my ‘Custom Workbench Build #1’ Article, I thought I would share how I went about building two hobby benches. The idea is to set up a good workspace for RC projects. I have created one standing bench for soldering and building and the other a seated bench which is also for building, but mainly for updating software on my flight computers.

GPS Reliability and Precision

The use of satellite-based navigation system has grown tremendously in the last decade. Almost every phone, many cars and even fitness watches have an inbuilt GPS receiver these days.As already mentioned previously, there are many safety benefits when using a GPS based flight controller, however, there can also be some issues using this technology though. Some reasons that relying solely on the accuracy of the GPS position may be problematic will be listed and explained in this article.

DJI Drone Pilots will Now be Forced to Take a Knowledge Quiz

Regulation of drone usage is not a new concept for many hobbyists. For the past few years, as the popularity of drones has skyrocketed, governments and regulatory bodies around the globe have tried to regulate and limit its use.

The Art of Balancing an EDF Fan

An unbalanced fan sounds terrible and yet many modellers don’t realise just how easy it is to get a fan to sound like a turbine. Most model aviation clubs are close to residential dwellings and so noise must be reduced. Many clubs have adopted strict noise policies in order to keep the surrounding neighbourhood happy. The reason we balance an EDF is similar to the reason we balancing a propeller, sound, efficiency and to minimise the wear and tear on the sensitive components in your model aircraft. No doubt you’ve heard the sound of a well-balanced fan and you’ll agree with me that it’s just a beautiful thing.

There are many ways to balance an EDF fan and in this article, I’ll cover two reasonably easy, yet, effective methods.

HKM390: Brushed vs. Brushless Motors

Today I received the HKM-390 On Road Bike from HobbyKing. As you know by now, the excitement you feel when you receive a package from HobbyKing feels as exciting as seeing on the presents under the tree on Christmas morning. Just like a kid on Christmas, I opened the box as quickly as I could.

Everything You Need to Know About Electronic Speed Controllers (ESC)

We take the humble speed controller for granted but it hasn’t always been this easy. Speed controllers have been around since Adam, however, they were nowhere near as sophisticated as today’s modern Electronic Speed Controllers.

How Brushed and Brushless Electronic Speed Controllers Work

An electronic speed controller (ESC) is an electronic circuit whose main purpose is to vary the speed of an electric motor and it’s direction. Whether the ESC is for a brushed motor or brushless the ESC interprets control information. This is not as in a mechanical motion as found in the case of servo units but rather in a way that varies the switching rate of a network of “Field Effect Transistors”, or more commonly known as FET’s. The rapid switching of these transistors is what causes the motor itself to emit its characteristic high pitched whine, this is especially noticeable at lower speeds. These FET’s also allow a much smoother and more precise speed control of the motor and in a far more efficient way than the older mechanical type of speed controllers. It has a resistive coil and moving arms, that we would see in many models a few years ago, especially in the model car world.

Model Aircraft Maintenance

Model RC Aircraft are subject to punishing extremes that take a toll on the components and the airframe. We have all seen landings where a plane hits the deck hard only to bounce back into the air, stall, and bounce on the runway again. The corpse of the crippled aircraft, along with any lost limbs is dragged from the strip to be put back together in a makeshift field hospital.
