RC cars can go very fast. Gas powered RC cars can accelerate for 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 speed 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 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 cars 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 TC3 and OFNA LD3 RTR. These
cars have an engine of Force .12 that gives a speed of 40 mph.
1/8th Scale Off-Road Gas Trucks combines 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
Monster Truck, Associated Monster GT, HPI Nitro Savage 21 RTR Monster
Truck, Tamiya Terra Crusher Gas Truck, 1/10 Traxxas Tmaxx or T-Maxx
Nitro RC Truck are some of the 1/8th scale off road gas trucks.
