Galileo Wheel
Galileo is a unique breakthrough technology, The Galileo Wheel, that combines a track and a wheel in a single component. This simple unique mechanism transforms wheel to track, or track to wheel, enables switching back and forth between the two mechanism modes within seconds. The technology offers the benefits of both traditional transport elements: the wheel with its energy efficiency suitable for high speed transport, smooth ride, maneuverability, and small footprint. The tracks with their superb traction to use in overcoming obstacles, smoothness of ride over rough terrain and towing capability, it’s capable to climb up and down the stairs. Mobility tracked robots needs analysis of tracked vehicles, no matter it is large or small, shows that the majority of these robots would be better off on wheels most of the time, but for a short but critical portion of their intended movement, it must be on tracks to achieve their mission. Galileo has developed the ideal mobility platform for vehicles, robots, wheelchairs and any other devices which needing track and wheels simultaneously. It is a great innovator! watch the video to see it in action.
New Design Idea for Mars Rover Wheels
Roving across the surface of the Planet is no easy feat. Just getting there is one heck of proposition in itself. Vast surfaces on our Red Planet companion make it difficult to choose where to cruise. Terrain must also be over come, which is no easy endeavor, just getting to the top of Husband Hill named after the Captain of the Columbia Space Shuttle crew, took months.
Life is not easy if you are the Mars Rover, you have so many worried; you are indebted to the taxpayer for your chance to explore another planet, you can never soak up enough Sun to remain fully charged and you have to worry about the Devil too. Those Dust Devils are mighty fierce although they are able to help clean off the solar cells.
Climbing mounds, hills and steep terrain is like a story of a Robotic System on the reality TV Show “Survivor,” the odds are against, you but you can never leave the island. Since steep terrain often has the best exploratory opportunities, one needs a robot which can easily transverse the Mars Landscape.
I propose we redesign the wheels, with angled spikes, which grip as it climbs and then retract once the wheel moves forward. The spikes will be no larger than those big nails you use to frame a house with and they will pierce thru the concave part of the tread on the outer surface of the wheel. This will allow the Rover to not fall over.
Further I propose using LED lights for forward vision so we can see on our screens back at home what is going on. Efficiency is the name of the game and we need lights, which do not suck up all the juice in the batteries that we need for mobility. Climbing steep terrain will take more energy from the batteries you see? LED lights are bright, but very low wattage and we can make them run using electromagnetic induction technology to charge a capacitor instead of the headlights working off a battery. We use the vibrational energy of the Rover’s own motor and the bumps on the ground that our Red Rover will travel over.
Currently there are some nifty micro-flashlights being used which you can buy which use a similar technique and are available thanks to the Everlight Flashlight technology research lab. These smaller flashlights work by shaking them for about thirty seconds and shine for about 6 minutes and they shine quite bright since they use a very bright LED light. Here is a link to this home use flashlight:

Here is a quick movie you can watch online to see how this technology works.

If they get too dim from too smooth of a trail, yah, we wish, then the system would revert back to the battery. Additionally we can run the spike system on the wheels by using the same energy source of the bumpy terrain, which activates tiny servos of .2 watts per wheel. Perhaps this is a good way to save energy and increase efficiency? Think on this.

RC Planes For Beginners – Multiplex Easy Star is One of the Best Trainer Planes on the Market
If you are like most, the desire to fly has exerted a strong pull from a very early age. For thousands of people, radio control aviation has been the means of fulfilling that dream. With a minimal investment of time and money, anyone can fly RC aircraft. However, choosing the right plane is very important. There are many good RC planes for beginners but if you want the perfect first aircraft look no further than the Easy Star RR from Multiplex.
Park flyers or trainers make great first planes and one of the best models on the market is the Easy Star RR (Receiver Ready). Beginner planes need to be relatively slow, stable and sturdy enough to withstand crashes. While Easy Star is fairly powerful for a trainer, it handles exceptionally well at slow speeds and is also a good glider. Easy Star is a high wing model, as RC planes for beginners should be. High wing planes have the wings attached on top of the body or fuselage. This adds to stability and makes the aircraft more forgiving, important when you are first leaning the controls. Constructed of durable foam material, Easy Star is tough enough to survive crashes without breaking and easy repairable if it does. For extra protection and safety, the electric motor is mounted on top with propeller facing rearwards.
While RC planes for beginners are available in electric and glow engine models, more and more new pilots start off and stay with electric power. Electrics offer performance comparable to glow-powered planes without the maintenance and messiness of fuel. Easy Star RR comes with ready built model and pre-installed Permax 400 Speed/6V electric motor, Multicont X-16 electronic speed control and 2 MPX Tiny-S servos. All you need to add is 3-channel transmitter and receiver and flight battery.
Many RC planes for beginners are too tame for pilots past the beginner stage but that is not the case with the Easy Star. Capable of performing loops and stalls, this trainer can be enjoyed by intermediate level fliers too. If you want to fly but think it may be too hard or take too long to learn, try the Multiplex Easy Star RR. Not only will you be getting a great beginner airplane, you will also have a model that continues to provide entertainment as you become better and better at RC flying!

RC Helicopter Tail Set Up
RC Helicopter tail setup can be frustrating if you let it. After reading this article you will have a better understanding on the procedures of the setup process. A tip that I have found for 450 size helicopters or smaller is to take a old turntable you know the one that played vinyl records. Then mount my helicopter to the part that spins I used a 1×2 drill some holes then put in some wing bolts to hold the board slide the board threw the skids then tighten it down This allows the tail to swing side to side. This way I can make the adjustments needed on the bench.
1. First thing we want to do is make sure all the parts are moving in the right direction
· Looking form the tail when we move the nose of the helicopter to the right the tail slider should move toward the tail or to the left. If we are flying by the nose this is the way most pilots learn. If the tail slider moves the wrong way we need to reverse the gyro this is best done at the gyro itself not with the radio.
· Next we need to make sure servo arm is centered when doing this we want the gyro in rate mode the stick center radio on and power supplied to the helicopter. Then just keep moving the arm or switching arms until you find one that is close to center.
· Next we adjust the linkage on 450 helicopters you can just slide the servo up and down the boom with the linkage attached but one thing to make sure of there is no binding and rod is not to long or to short. What we want to accomplish is that the tail slider has a little pitch pushing the nose right to allow for main motor torque in a hover. If just a little left of center works well.
· Now we need to go in to the radio some types cannot get all the details of how to get there for so many radios out there but we need to find the gyro menu and set first to setting to -50 and the 3rd switch setting to +50 for are gain this is a good place to start
· Now we are ready to spool up and see if are tail holds If is spins counterclockwise we need to shorten the tail linkage rod. Or if is spins clockwise we need to lengthen the tail linkage rod.
· Next we need to get the helicopter in a hover and check the gain whit the helicopter in a hover if the tail wags a little the gain is to high I found on my 450 I set at 32%.
Sometimes I have to play with sliding the gyro or adjusting the tail linkage rod to get it just the way I want. Just keep fine tuning and you will get it where it holds rock solid Hope I helped someone Have a great day!

RC Planes for Beginners – Ready to Fly Radio Control Planes
Since the beginning of time, humanity has been fascinated with flight. From early attempts to imitate birds to the application of mechanical ingenuity and the scientific method to the problem, man finally, after much trial and error, on Dec. 17, 1903 accomplished the first successful, controlled, heavier than air flight. Since that day at Kitty Hawk, North Carolina, progress has taken place by leaps and bounds until today, global air travel is commonplace. However, not everyone has the time or money to jet to a vacation in a far away land, or to own and operate a private plane. Yet we still may remain enthralled with flying and the airplanes that make it possible. Learning to fly electric, radio remote controlled model planes is a realizable and inexpensive way to satisfy our desire. For those with the flying bug, simple, affordable, easy to use RC planes for beginners are a great place to start.
A quick trip to the local hobby store or a search online will yield many different options of electric Ready to Fly (RTF) RC planes for beginners, from toy to micro planes, park flyers to trainer, and biplanes to gliders. Some RC models are only partially assembled or come with complicated plans for building from scratch. Some enthusiasts love model building, but the majority of newcomers are better served by pre-assembled planes, with all necessary parts – motor, radio system, servos, battery pack, etc. – packaged together and pre-installed. With RTF planes, all you need to do is insert batteries and you are ready to go. Beginner planes, slower flying and more stable than advanced models, are also easier to fly and to repair. Because they are so forgiving, they allow you to build your eye-hand coordination at your own pace.
Another advantage of RC planes for beginners is their affordability. The ability to start with an inexpensive plane is beneficial to novice pilots because crashes are bound to happen. Look for a beginner plane that is crash-resistant but simple to repair when repairs are needed. Also be sure to select a model for which replacement parts are readily available. If they aren’t and you total the plane, your only option is to replace it and that can become expensive.
