What you should consider before converting your RC airplane gas engine to an electric motor system. With the changes in RC electric motor technology it is possible to fly ANY size model using RC plane electric motors. The biggest leap in making this possible has been two fold. First we have model airplane electric engines that are powerful enough, not to mention much more efficient, that they rival or even surpass gas/slimers/smokers/nitro hogs, or whatever else you may call RC airplane gas engines.

In fact you can expect to see an increase in the performance of a model airplane in several areas. Your take-off is shorter, climb rate will increase and you can now fly in areas that have noise restrictions. The debate between the benefits of RC plane electric and gas motors are as controversial as those between PC and Mac users. It will continue for as long as they are both in existence.

Some questions you might be asking before you convert your RC model airplane's gas engine to an RC electric motor...

How long will the battery allow me to fly? With today's Lithium Battery technology, you can easily expect 10 minute flights, even in bigger aircraft. The days of overheating the batteries and fire hazards are almost non-existent. There are many add on features that you can now purchase that all but eliminate battery hazards. Such as temperature monitors and voltage indicators.

Here are some questions to ask before you start buying any components. These questions will help determine what components to buy.

1. What is the radio control plane that you are wanting to convert? Is it a trainer, sport plane, 3D etc.. This is important because you will need to determine the electric motor based on your models capabilities, and what you want it to do.

Example: Hangar 9 Arrow with a.40 size gas engine.

Would require an electric RC motor equivalent to a AXI 2826/12 External Rotor Brushless. This motor would allow this model to perform basic aerobatics with its semi-symmetrical wing.

Specs of the Hangar 9 Arrow

You will need these numbers to help determine the motor, battery, and prop requirements.

• Wingspan: 63 in
• Overall Length: 52.5 in
• Wing Area: 710 sq in
• Flying Weight: 5.7 lb (as a radio controlled gas plane)
• Engine Size: converting a standard.40 size RC gas engine to an RC electric motor.

Now you need to determine what type of batteries you will need. This is based mostly on your budget and time till land variable. In other words, how long do you want to fly for and still get performance.

The most obvious choice is going to be a Lithium Polymer battery, this is the most advanced battery technology available for RC model airplanes. They are also the most expensive. Other older battery technologies are available, such as, lithium ion and nickel metal hydride. They can do the job, but at a weight cost and flying time consideration. So choose carefully.

In the Arrow Example: We will use a 4200 mAh 11.1V Li-Poly Pack. This was determined based on the flight performance we were after, some aerobatics, but mainly stable easy going flying. Nothing too extreme.

As with any gas RC plane conversion to electric (or any electric radio controlled airplane for that matter), you will have to consider an ESC (electronic speed control). This hooks up to the motor, battery, and receiver. You will need to pick one that can handle the required number of battery packs, servos and have programmable features. This will make life easier for you if you pick one that is feature rich. Of all the components, this is one to spend a little more on. You will be glad you did.

For this example, we used a 40 Amp Brushless Controller with Program features. There are lots of manufacturers of ESC's so take the time to reseaRCh them.

Prop Selection is an important consideration. You need to be aware that with an electric conversion there is a possibility that your model plane will not have enough clearance when using an electric motor prop. It may need modifications to the landing gear (making them longer) so that the prop has clearance.

For the Arrow example we used an APC 13x10 propeller. Most electric motors now have a table that you can find on their website that will recommend the propeller range to stay within.

One final consideration with RC gas planes converted to electric. You always need to factor in cooling of the battery pack and esc. In fact many modelers, including myself, put the ESC on the outside of the plane, usually I mount it under the engine on the firewall. You also need to make air vents to cool the battery inside the model. Without this, you run the risk of overheating batteries and ESC's.

If you have any comments or need more help, I would be glad to answer any question you have. Please post a question at our HTMRCA Blog for the quickest response to your questions. Or you can leave a comment about this article. You can also write just to say hi. This is one big community and it's great to get to know other electric radio controlled plane pilots.

Good Luck, and Happy Buying and Flying,

Feel Free to contact me with any specific questions about electric conversions. I love to help other RC airplane Hobbyists. contact@howtomakeRCairplanes.com. By Carl Bayer - I have been flying and building radio controlled airplanes, helicopters, boats and cars for over 20 Years. I have been specifically building and flying electric airplanes for over 10 years. My latest interest is to convert balsa wood kits with gas engines, to models with electric motors. This has been more realistic to do lately because of the huge leap in battery technology and it has been a very fun way to still make balsa kit planes from scratch, but not worry about any gas problems. If you would like to know more about how you can build Balsa Kits too, then check out my complete building system book on How To Make RC Airplanes http://www.howtomakercairplanes.com.

Comeback of a Sports Car Legend:

 

The countdown is running for the new era Scirocco: the third generation of the sports car will already be arriving on the market in August. Volkswagen is staging the comeback of a legend with the debut of the two-door car – Scirocco generations I and II wrote history as the most successful Volkswagen coupé of all time with about 800,000 units sold.

Cult status. In particular, it is the original Scirocco presented in 1974 that has long held cult status. Because, in contrast to many of its competitors of that time, the Scirocco – designed by Giorgio Giugiaro – was an affordable car with everyday utility, and front-wheel drive also made it a safe sports car for use every day of the year.

Fascination. The new Scirocco is extending this tradition. It offers pure driving pleasure, a new powerful design, high-end technologies such as DCC adaptive chassis control and the new 7-speed DSG dual clutch transmission. Plus: exclusive use of efficient turbo engines with up to 147 kW / 200 PS

Power, space for four adults despite its sporty lines, an extremely high level of safety and the everyday utility that is typical of every Volkswagen. This mix of passion and logic costs far less than one might guess based on the car’s key data.

New paths. Although the third generation of the Scirocco follows exactly the same positioning as the first one, Volkswagen very intentionally avoided retro elements. In this regard too, the Scirocco of the year 2008 is a conceptually counterpart to the original version: because in the mid-1970s the successor to the Karmann Ghia also set out on new paths, both technically and visually.

Cost of Hood vents?? And a superb paint job?

I sport an infiniti g20 and i was wondering if i could get those cool vent things on the hood to make it look more sportier and i was thinking about also painting it black and tinting the windows, this will rack up a bill of???? and im not looking for the best paintjob ever but one that is par and it is currently red so yes they will have to do that other stuff,

I'd say $2963.15 plus tax and shop supplies.

FEATURES: Style and elegance
British brand of luxury off-roaders and SUVs still the last word on good looks versatility Friday, June 18th, 2010 17:32:00 Like Rolls Royce, Aston Martin and Mini, Land Rover is the quintessential British brand, restrained but brimming with ideas and it is this combination that has put it in good stead with motorists the world over.
