Question: Which radio-controlled car is powered by the simplest organic nitro compound?

Context paragraphs:
Schumacher Nitro 21 XT-R 3E: The Schumacher Nitro 21 XT-R 3E is a radio-controlled car made by Schumacher Racing Products powered by a nitro fuel engine.

Tamiya Radio Controlled Nitro Vehicles: The Tamiya Radio Controlled Nitro Off-road Vehicles entered the radio controlled (RC) nitro engine (glow engine) powered 1/8 scale truck market in July 2002.  Produced by the Tamiya Corporation of Japan, these 1/8 scale trucks are designed for stadium competition.  Tamiya's first nitro truck, TR-15, was introduced in 1994.  Second truck was Mad Bison, released in 2000.  Third attempt, Terra Crusher, departed greatly from the previous two.  Terra Crusher (TG-01), released in July 2002, capitalized on the off-road monster RC boom of the time; subsequent trucks include the Wild Commando, TNX (TGM-03), TNX 5.2R, and Nitrage.  The trucks perform in competitions for Remotely Operated Auto Racers (ROAR) abbreviated as ROAR.  ROAR is the sanctioning body of competitive radio-controlled car racing in the United States and Canada, overseen by IFMAR (International Federation of Model Auto Racing).

Schumacher Menace: The Schumacher Menace is a radio-controlled car made by Schumacher Racing Products powered by a nitro fuel engine.

Nitronate: A nitronate (IUPAC: azinate) in organic chemistry is a functional group with the general structure 2− .  It is the anion of a nitronic acid, a tautomeric form of a nitro compound.  Just as ketones and aldehydes exist in equilibrium with their enol tautomer in basic and acidic conditions, nitro compounds exist in equilibrium under basic conditions with their nitronate tautomer.  The base deprotonates the α carbon, or the carbon directly attached to the nitrogen.  The nitronate has two different resonance structures, one with a negative charge on the α carbon and a double bond between the nitrogen and one of the oxygens, and another resonance structure with a double bond between the nitrogen and the α carbon, and no double bond between the nitrogen and the oxygens.  A nitronic acid is also called an aci form.  In the Nef reaction nitronic acids are degraded to ketones.  They can be alkylated on oxygen and used as a dipole in 1,3-dipolar cycloadditions.

Model engine: In radio-controlled modeling, a model engine is an internal combustion engine used to power a radio-controlled aircraft, radio-controlled car or radio-controlled boat.  Other forms of aeromodeling, such as free flight and control line aircraft, and ground-running tether car models also use these engines.

Radio-controlled drifting: Radio-controlled drifting refers to the act of drifting with a radio-controlled car (R/C car).  Special R/C cars are equipped with low-traction tires to aid in the ease of inducing and maintaining controlled oversteer.  Car setups are often modified to allow the car to drift more easily, by replacing motors, shocks, tires, weight balance, brakes, and other factors.  R/C drifting is typically performed with four wheel drive (4WD) electric R/C cars, although some practitioners use gas and nitro powered R/C cars and/or rear-wheel drive vehicles.

Schumacher Menace GTR: The Schumacher Menace GTR is a radio-controlled car made by Schumacher Racing Products, powered by a nitro fuel engine.  It is essentially a Schumacher Menace made into an on-road car.  This is accomplished using lower shock towers, shorter dampers, different tires, wheels and other small adjustments.  The end result is an on-road car that is just as fast as the Schumacher Fusion in a straight line speed but that can corner a lot faster due to its wider chassis and more stable nature.

Nitroglycerin: Nitroglycerin (NG), also known as nitroglycerine, trinitroglycerin (TNG), trinitroglycerine, nitro, glyceryl trinitrate (GTN), or 1,2,3-trinitroxypropane, is a heavy, colorless, oily, explosive liquid most commonly produced by nitrating glycerol with white fuming nitric acid under conditions appropriate to the formation of the nitric acid ester.  Chemically, the substance is an organic nitrate compound rather than a nitro compound, yet the traditional name is often retained.  Invented in 1847, nitroglycerin has been used as an active ingredient in the manufacture of explosives, mostly dynamite, and as such it is employed in the construction, demolition, and mining industries.  Since the 1880s, it has been used by the military as an active ingredient, and a gelatinizer for nitrocellulose, in some solid propellants, such as cordite and ballistite.

Acetonitrile: Acetonitrile is the chemical compound with the formula CH3CN .  This colourless liquid is the simplest organic nitrile (hydrogen cyanide is a simpler nitrile, but the cyanide anion is not classed as organic).  It is produced mainly as a byproduct of acrylonitrile manufacture.  It is used as a polar aprotic solvent in organic synthesis and in the purification of butadiene.

Nitromethane: Nitromethane is an organic compound with the chemical formula CH3NO2 .  It is the simplest organic nitro compound.  It is a polar liquid commonly used as a solvent in a variety of industrial applications such as in extractions, as a reaction medium, and as a cleaning solvent.  As an intermediate in organic synthesis, it is used widely in the manufacture of pharmaceuticals, pesticides, explosives, fibers, and coatings.  Nitromethane is used as a fuel in various motorsports and hobbies, e.g. Top Fuel drag racing and miniature internal combustion engines in radio control, control line and free flight model aircraft.
