Electric RC Models were looked upon as mere toys in the past. But now a RC model powered by light weight energy dense Lipo batteries along with powerful efficient brushless motors can now run neck-to-neck with their glow powered cousins when it comes to power and longevity.

Choosing an RC electric motor for your RC Models isn't quite as straight forward as ordering the recommended size glow engine. All the different brands, sizes, and specifications can make choosing a motor quite intimidating if you're new to the hobby.

Understanding the basic fundamentals outlined here is essential for choosing a suitable motor for your models. the more experience you have tinkering with different setups, the more confident you will be when choosing RC electric motors for different types and sizes of RC airplanes...Now just go and learn here

Motor Specifications
When shopping for RC electric motors, you will need to understand what the following specifications mean.

Voltage Constant
Kv is the "Voltage Constant". This is how many RPM's the motor turns for each volt applied. Actually, it's a tad less because motors aren't 100% efficient.
For example, if you apply 12volts to a 200Kv motor, it will turn at just under (12 x 200) 2400 RPM's.

Torque Constant
Kt is the "Torque Constant". For all motors, Kt= 1355/Kv. You'll have to ask someone smarter than me where the 1355 comes from, cause I don't have a clue! Just accept it for what it is.
In a nut shell,...Continue Reading

To Start a Fun Night Flying, it is important to understand some basic concepts about Night Flying and lighting system for RC Aircraft

RC Night Flying is the act of flying a radio-controlled model airplane at night! I do not know when the practice of night flying began, but I would assume it has been rather recent in the history of model aviation. With advances in technology producing more powerful engines and lighter components, it is now possible for a small aircraft to carry the additional components necessary to illuminate an aircraft in flight. After all, if you can't see it, you can't fly it.Then Turn to the real problem: how to illuminate an aircraft in the dark?

The best way to illuminate an aircraft is to put lights on the aircraft. And in order to do this, one needs a light source and a power source (to power the lights). If your power source is a battery pack, it is not advisable to use the same batteries to power your lights that are being used to power your receiver! This is an accident waiting to happen.



One of the simplest (yet least elegant) solutions is to use LED Light Belt to light up the airplane. This has the advantages of being economical (LED Light Belt are cheap,about 5usd/mtr), Extremely light weight,quick to set up, and they require no power source. Their disadvantages, however, include additional weight to the aircraft, disruption of the airflow over the aircraft surfaces (increasing drag and altering flight characteristics), and...Continue Reading

How to Become An Excellent 3D Flying Pilot

There are more and more Pilot Turn to 3D flying instead of flying other Basic and Trainer Model Airplane. So how they practice to be an excellent 3D Flying Pilot?

3D Flying Pilot

During the 3D maneuvers,experiment and practice with your plane until you learn everything you can about it. Here are the skill share from experienced 3D flying pilot

3D maneuvers

FIRST STEP:
Programming your radio for 3D flying is key to being an awesome 3D pilot. See our webpage on programming your radio first.

SECOND STEP:
Trimming out your plane for 3D flying is critical to being an awesome pilot. Right thrust and up thrust must be optimized. Perfect right thrust and up thrust for hovering is different than for sequence flying though they are close. This cannot be changed on a day to day basis, so you need to decide what is most important to you. It's easier to fly sequence with 3D right thrust and upthrust than it is to fly 3D with sequence right thrust and upthrust, so if you are primarily interested in 3D, trim the plane out as follows: On a day when there is little or no wind, fly level to the center of the field at a slow speed, pull to vertical and roll to see the canopy of the plane as if you were going to do a hammer. Let the plane slow to almost a stop. Go to full throttle and let go of the sticks and fly for several seconds. If the plane veers right of left, adjust the rudder to keep the plane vertical. Do this 10 to 20...Continue Reading

Start a model aircraft engine is surprisingly easy, it’s prime can be hand-started in a couple flips. But some propellers have extremely sharp edges.For your own safety scrape and sand this edge down. If you try to flip the propeller by hand you will get a nasty razor cut. and you may heard that some people use a Chicken Stick to start their engines if they didn’t get an standard electric starter Why start engine can be so “Informal”? Are they really all acceptable?

“Chicken Stick” Start Engines
People use a Chicken Stick to start their engines for safety purposes. A Chicken Stick is a small, hand-held, rubber coated stick that is used to flip the propeller and keep the fingers out of the propeller arc.

Start Engines

Hand Starting a Glow Engine
My first recommendation for starting an engine is to attempt hand starting before automatically reaching for an electric starter. It is faster and easier and not as hard on your engine. Follow these steps closely and you will be amazed at the success you have starting your engines.

Hand Starting a Glow Engine

Before you attempt to start your engine ensure that:
Spectators are a safe distance away and behind the propeller.
There is nothing that can get pulled into the propeller.
The glow igniter is not connected.
The fuel tank is full.
The propeller is securely mounted using a real wrench — not a four-way wrench.

If you have never run this engine before or for any reason think the high-speed needle valve is not...Continue Reading

Gas Model Airplane Shopping Tips (RTF, ARF, Kit)

Gas Radio Controlled Planes are more complicated, and which can be found in many different variations all suiting different levels of skill and passion. So it is probably a good idea that only more experienced fliers fly gas planes.

gas model airplane

Gas planes usually have more expensive maintenance costs, as well as greater start up costs as opposed to electric planes. Gas planes are also difficult to learn how to fly, so When choosing the right gas plane, you will need to decide if you are going to need an instructor or if are you going to learn by yourself. If you are a beginner you should get a trainer gas rc plane, as this type of plane will help you to learn good flying skills. There are a number of options which you should look at when buying a gas radio controlled plane:

*You should choose a trainer gas plane if you are a beginner
*Wings should be high up on the fuselage above the cabin area
* wing should be large because more lift is created and will make the airplane fly slower
*Look for tricycle landing gear to make landings easier
*A flat bottom wing air foil section for better lift
*Buy a 4 to 6 channel transmitter now
*The bigger the plane, the easier it is to fly

Ready to Fly Gas RC Planes(RTF)
Picking out the right gas rc plane is very important as you don't want to waste your time and money on bad ones. Not too many years ago remote control airplanes required hours and hours of building...Continue Reading

http://v.youku.com/v_show/id_XMzY1MTQ4MjI0.html

There are many question about “how to use Mini Servo Sectionboard Power Box for gas plane with 20A UBEC?” they are all pointed out this mini power box are ordered from SDSHobby.net.What is this Mini Servo Sectionboard Power Box? And why is it so hot?

Mini Power Box

This Mini Power Box Pro is mainly used for the servo with large regular vane’s airplane, such as gasoline engine. This product can distribute several strings’ power. The section board integrates CDI remote flameout switches and reserves position for receiver, which make servo’s lines convenient and tidiness. If you use double powers input to the power supply, it will be more stable and more security.

Produce features:

1. Eight channels for input, and sixteen channels for output.(every one channel input with two channels output )
2. Integrates CDI remote flameout switches. Through each channel of the remote controller or switch channel (usually choose a switch channel) can make the gasoline engine’s CDI on or off by remote control.
3. Independent CDI power supply socket. Receiver power completely separates with the CDI power, so you should not worry about that CDI arouses high frequency signal will interfere the receiver, and the LED display the state of the power supply at real time.
4. LED display the state of the electric voltage at real time, and LED...Continue Reading

Guide to Make Your RC model Airplane More Conspicuous–Covering Film &Sealing Iron


Covering your RC model Airplane is one of the last things you do, but most of the hobbyists have not experience of sealing covering film. It’s not complete but also requires a lot of consideration if you want a result that’s going to handle the loads imposed by the model as well as look good. Which covering film material you select will be based on numerous factors, including the following;

Fuel proofing
Weight
Strength
Colour availability
Pricing



Note that even with the same covering there can be a reasonable deviation in the weight (per metre square) due to the mass of the pigments in the material, different colours have different weight


Covering Weight Application method Details
Japanese tissue 7gsm Dope One of the lightest coverings you can obtain. Note that this will require adhesive to apply to the airframe and doping or similar sealing.
Laminating film ??? Iron-on Typically available in 1.5, 3, 5 and 10mil thicknesses, laminating film is an excellent low cost source of plastic type covering film. Even in the 1.5mil thickness laminating film exhibits exceptional strength to weight ratio.
Nelson Lite Film
So-lite
Solite 21gsm Iron-on Considered to be one of the better iron on ultra-light films.
Litespan 30gsm Iron-on Litespan is a very light synthetic tissue used in place of normal tissue/dope. It is much stronger and...Continue Reading

There are many different rc aircraft types associated with radio control flying, many of which you’ll see at an rc flying club field. If you’re completely new to the hobby and are wondering what these types of rc aircraft are, then this page will introduce you to them.

Remember that the word air craft covers all flying machines, not just conventional airplanes. Also bear in mind that the most common rc aircraft types (airplanes and helicopters) can be scale, semi-scale and non-scale models. These three terms refer to the reality of the model; whether it replicates a real aircraft (scale), is a close representation of a real aircraft (semi-scale) or is a completely made-up design (non-scale).

Whether you end up flying scale, semi-scale or non-scale rc aircraft comes down to your own personal preference. There are plenty from each category to choose from these days, a reflection of the popularity of the hobby!
The basic RC aircraft types

For the purpose of this page, rc airplanes and helicopters have been split into their own types; simply categorizing the two as aircraft types would be a bit broad given the variations available.

Collectively, rc planes account for the largest number of aircraft in the hobby. Having said that, the popularity of flying rc helicopters has grown tremendously in recent years as electric rc helicopters have surged onto the scene, and the gap between the number of rc airplane pilots and rc helicopter pilots has become much smaller than...Continue Reading
