HOW DO I TUNE A NITRO ENGINE, IS IT EASY?

Before you can do any tuning to your new RC Nitro, you need to break the motor in first as the materials inside the engine change mass with heat so in order to ensure the engine components work well together and have been lubricated and heated properly you Must ensure your motor has been broken in without any tampering or pre tuning as this can harm your motor and void warranties.  We suggest you look at this video and follow all manufacturers instructions included with your New RC.  Breaking in a Nitro Motor

By far the steepest learning curve for a nitro rookie is learning how to tune a carburetor. It can be awkward at first, but with a little effort, you’ll get it and never forget how to do it. Before we start adjusting needle valves, let’s consider the role of the carburetor and how it works. Properly tuning a carb is much easier once you understand how it functions.  Check out this link from RC Car Action that explains the do's and dont's How to Tune Nitro Engine

DO NITRO CARS REQUIRE MORE MAINTENANCE?

The engines in nitro cars use Premixed Nitro fuel rather than batteries to power them. Because they run using this oil- and methanol-based engine, nitro RC cars require more general maintenance and care before and after use than a battery-powered electric RC car does.  After you use a nitro RC car, you must remember to drain its fuel tank, clean and oil its air filter and add oil to the engine. Also, nitro cars are also much more susceptible to wear and tear on the engine than their electric counterparts. Here is a great link to Maintaning your Nitro car - NITRO CAR MAINTENANCE

ARE NITRO CARS IDEAL FOR BEGINNERS?

Because the engines in nitro cars need to be tuned OFTEN to provide optimum performance and maximize the engine life, you will need to have some expertise and experience when using these vehicles.  Nitro cars do not have on board computers keeping the car tuned for changing heat or cold conditions which affect a Nitro car on a day to day basis.  If you get the tuning on your car perfect on a 25 degree day then the next day the temperature is 17 degrees your tuning will be effected and you will need to re tune or end up paying for a tune up by a pro which can be costly unless you understand that you need to learn and practice the art of tuning.  It does not matter how much you spend on a Nitro car the science is exactly the same and a learning curve is a given.

Also, nitro RC cars are typically harder to control than a base Brushed electric counterpart. With this high-speed driving often comes a tendency to crash the vehicle more often. If you hit a wall at these high speeds, you can literally destroy your car.  having said that Brushless electric cars these days at the higher end of the spectrum are indeed faster than most nitros. Also, because you will need dexterity to control these cars and you will need to use flammable, poisonous fuel to refill them, nitro RC cars are not a wise investment for young children.  You must ensure young children are under strict supervision when operating any Nitro car.

But if you are looking at investing in a nitro powered RC car and think you have the patience and are prepared to learn and make mistakes along the way nitros can be very rewarding.  Also consider purchasing a nitro car kit such as the Starter Kit so that you have everything you need to power your car right away.

WHATS THE DIFFERENCE BETWEEN BRUSHED AND BRUSHLESS TECHNOLOGY?

Though inexpensive, traditional “brushed” electric motors offer short run times and limited power. Current passes into the heart of the motor through soft to semi-hard blocks of material called brushes which contact the spinning commutator. Friction from this contact reduces power and causes wear, eventually requiring brush replacement.

New Technology “Brushless” motors avoid these inefficiencies. Current passing around the outside of the motor’s can causes magnets on the motor shaft to follow in a circle (imagine the passing current acting like one magnet, pulling the magnets on the motor shaft toward it). Brushless technology is more expensive, but also more efficient equating to much longer run times with fewer break downs- and can be MUCH more powerful!

WITH A BRUSHLESS MOTOR, DO I ALSO NEED TO RUN A BRUSHLESS (ESC)?

Yes. Brushless motors will not work with non-brushless ESCs - the two technologies are completely incompatible. A brushed ESC just pumps out current like a fire hose pumps out water. A brushless ESC spreads current in a precise pattern to different places in the motor.

WHATS A GOOD BEGINNERS AIRPLANE TO START WITH, HIGH OR LOW WING?

Choosing a plane can be a very difficult and intimidating decision and there are some things to look for that may help you choose wisely.   Here are some important things to consider.  Firstly it takes a little while to gain the muscle memory and response time to fly a radio control plane.   A High Wing slow flyer will give you more time to react to mistakes and improper inputs.  Slow flyers don’t seem cool at first but you’ll be surprised at how quickly you fall in love with a good flyer before the one that looks cool.  Aircraft like the ever reliable CUB the Beaver or the New Discovery range of Park Flyers will be a great investment as your first plane.

These planes are great to start with because they are electric easy to use and maintain and mainly constructed of durable inexpensive foam. Today’s electric R/C planes have plenty of power and are much easier to fly and maintain than fuel-based planes.  Gassers and nitro planes are pretty awesome, but learn to fly, crash and repair before you add the complication of an internal combustion engine.

These types of planes are made of foam, Foam is your friend.  The fact of the matter is your first plane will more than likely be trashed. Foam is durable and easy to repair. Balsa planes are beautiful and there is nothing like them.  They are works of art that look great on the shelf and in the air. Not to mention they stand the test of time. But don’t start with that beautiful balsa plane.  Learn on an inexpensive foam plane that can take some abuse. 

Don’t go too small, it’s important to choose the right size plane for the space you have available. In general the smaller and lighter your plane is the more crashes it should be able to endure.  This also means that it’ll be more sensitive to wind and will probably be unstable. Bigger planes tend to be more stable, but they need more room to take-off and land.  Park flyers are a good size to start with and are usually around a 36” wingspan and require a 600 X 600 foot open area to fly.

If you think this is a hobby you want to stick with, a simulator is a worthwhile investment.  They are very accurate these days and around 20 hours on these SIMS can save you plenty of dollars not to mention give you a confidence builder.   Two of the best on the market know for keeping up with industry standards and realism is Realflight and Pheonix, believe me do not bother with anything else...

Happy Flying!
