Trust me, rc cars can go very fast. RC gas cars can accelerate from 0 – 60 mph in less than 2 seconds. But the hall of fame cars are all electric cars. So the best guess can be that electric RC Cars seem to dominate. On the other hand talking of racing over 30 to 60 minutes long, gas cars can consistently post the fastest lap speeds. R/C cars started in 1/8th Scale On-Road Gas class. And when it comes to pure performance, nothing beats the speed and realism of 1/8th scale on-road gas cars. They give speeds from Zero – to – sixty miles per hour (mph) in 1.5 seconds, at racing speeds of over 70 mph. And these are real speeds as captured by radar guns. For power, these cars use 3.5cc 2-stroke engines capable of producing 2 horsepower. Power is delivered via a 2-speed or 3-speed automatic transmission to a 2WD or 4WD full suspension chassis. Wide, low profile foam tires produce the grip needed to propel these machines to incredible speeds.

1/10th Scale Off-Road RC Electric rc Trucks are probably the most popular class. These cars (i.e. buggies, racing trucks, monster trucks) can be run on almost any type of surface. Dirt, dust, water, and jumps add to the fun. These cars also make use of the standard 540 electric motor. The main difference to on-road is the suspension system.

Long shock absorbers keep RC electric trucks stable over bumpy surfaces.

Tires are also bigger, have deeper threads or spikes, and are made of rubber. 2WD is still the most popular class for off-road, although there are plenty of 4WD cars to choose from. Early electric rc cars and trucks were 1/12th scale run on-road. Today’s cars are run indoors and outdoors, on asphalt or on smooth carpet. These cars make use of 540 size electric motors, powered by 4 or 7 cell batteries. Pan chassis with direct drive transmission are the norm. Foam tires are used and lightweight Lexan bodies are used.

Because of its small size, 1/12th scale cars are lightweight, and have good power-to-weight ratio. 30+ mph speeds are achievable even with the basic Mabuchi stock motor. 1/10th Scale Gas Touring Cars are similar to electric touring cars, but with more power and 2-speed transmission. At 190mm, these cars are slightly narrower and smaller than the 200mm models. These cars are tamer in performance as compared to 1/8th scale on-road gas, but still capable of speeds in excess of 50mph.

Performance at the track is similar to their electric counterparts. At twisty turns, electrics are usually faster. However, the 2-speed transmission allows gas touring cars to achieve higher top speeds. Some of these cars are Team Associated Nitro gas car TC3 and OFNA Nitro gas car LD3 RTR. These cars have an engine of Force .12 that gives a speed of 40 mph. 1/8th Scale Off-Road Nitro RC Trucks combine the speed and power of a 3.5cc engine with the fun of running in off-road conditions. These buggies need and use 4WD to transfer the power of the 3.5cc engines to the track. Sticky rubber tires provide the much-needed grip. HPI Savage 25 Nitro RC Monster Truck, Associated RC Monster GT Truck, HPI Nitro Savage 21 RTR RC Monster Truck, Tamiya Terra Crusher Nitro Gas RC Truck, 1/10 Traxxas Tmaxx , T-Maxx Nitro RC Truck and Traxxas Rustler are some of the 1/8th scale off road nitro rc gas trucks.

Nitro rc cars and trucks look cool. It’s a pride to own one and it looks great on road and off road. But they do cost a lost as well. Well, in order not to end up with a piece of junk or spend way too much on a simple model, some tips should be kept in mind.

For a beginner nitro rc stadium trucks or monster trucks can be great fun. But monster trucks are not as fast as stadium trucks. A Nitro rc Stadium truck can nail down to 50-60 mph and can take huge jumps but tear up some asphalt.

Rc Buggies are also pretty much like stadium trucks. HPI MT2 18SS seems to be a pretty good truck. If you’ve never had a high powered nitro or electric car before, you might want to start with a 4wd car. They’re much easier to control.

RC kits are easy to use and readily available. They are fairly popular too. Another plus point for the same is that help for them is also readily available. With an RTR kit you get a decent radio and the car for a decent price. It is always advisable to find a manufacturer that has good following. It leads you to find parts, hop ups, technical advice, etc easily available. Parts for RC kits are also readily available.

While buying kits there might some other things that need to be bought along with the RC kit or separately. Most of the time, the kits come with a car and a motor only. Some more advanced models come without motor at all. The RTR RC kits usually come with a radio and actually do not require much building up. They are around 97% completely built. You will also need to buy a nitro fuel that is especially for the Remote Control cars. Keep a check not to end up buying a Nitro Fuel for a Remote control Plane. For radio controlled cars, petrol can also be a fuel source.

A glow plug igniter is also required. They come in various different shapes and kinds but more or less all are same but some come with a meter to show how much of fuel is left. A fuel bottle is also necessary. They are not an absolute necessity, but make pouring fuel into the tank much easier than out of a one gallon can. Investing in a good air filter is always a wise decision. This would make up all the necessary things while buying a Nitro car. Other handy stuff that may come in useful should be tucked in a fishing tackle box. This would include things likes screw drivers, a cleaning sock, needle nose pliers, some spare screws, glues etc. Put all these things into seperate slots to make it a little more organized.
If you have had some experience with RC cars earlier then build-it-up kits are also advisable. Build-it-yourself and unassembled kits generally have higher quality parts and you can choose your own engine and other parts. This is more advisable for people who have already had some equipment and move from one model to another. So the cost drops after the initial investment. This also helps to know your kit in and out and makes you more familiar with your vehicle.

A nitro rc car fuel system can be hard to master. Here’s how it works as well as some handling tips.

Fuel Tank System

RC gas car fuel system

The fuel delivery system of a nitro rc car:
1. Fuel tank
2. External fuel filter
3. Primer
4. Fuel line
5. Air pressure line

Nitro RC car Fuel Tank
Fuel is stored in a fuel tank. Some fuel tanks have an internal fuel filter while others do not. An external fuel filter should be used with fuel tanks that do not have an internal fuel filter.

rc fuel filter
External Fuel Filter
To prevent debris from entering the engine, a fuel filter is placed between the fuel tank
and the carburetor. If the tank has an internal fuel filter, there is no need to use an external fuel filter.

Primer
To start an engine, it must have fuel in the carburetor. The primer helps push fuel into the carburetor. This is done buy pushing the primer up and down several times. You can actually see the fuel inside the transparent fuel line move from the fuel tank to the carburetor.

Fuel Line
This is a rubber tubing allowing fuel from the fuel tank to reach the carburetor. Air Pressure Line Rubber tubing coming from the tuned pipe going to the top of the fuel tank. Exhaust air from the tuned pipe helps to pressurize the fuel tank, helping fuel move from the fuel tank to the carburetor.

Tips on handling a nitro rc car fuel system:

Tip 1:

To prevent confusion, try using different color tubing for the air pressure line and the fuel line. For example, use orange for the air pressure line and blue for the fuel line. This will help prevent mistakes in connecting the line. For example, if you mix up the connection, your car will not start.

Tip 2:

I personally prefer a fuel tank with a primer because I can easily force fuel into the carburetor before starting the engine. Some fuel tanks do not have a primer, and I find it takes a few pulls on the pull-start to get fuel to even reach the carburetor.

Hope I have helped you with this info on an rc car fuel system.

Cheers to your rc hobby!
