What difference between on-road RC Nitro petrol car and an off-road RC Nitro RC petrol Truck engine?

On Road Engines are designed to operate at higher rpms. They produce more HP. But they are fuel hungry. A typical off road buggy race will require 10min pit stops, While in Nitro on road they require about 5min. The smaller the carb hole, the less power and more fuel mileage you get.

On Road:
1/8th Buggy based: Offroad / Onroad .21-.28 RPM: 42000 / 38000 6.5mm carb restrictor
1/8th Open: .21 RPM:45000 9mm carb restrictor
1/10th Sedan: .12 RPM:44000 1.73hp

Offroad:
1/8th Buggy: .21 engine RPM: 42000 6.5mm carb restrictor
1/8th Truggy: .21-.28 RPM: 42000 / 38000
1/10 Stadium: .12 RPM: 30000 .7hp

"TAMAK" Thanks for this kind information. Which one is the best for the race, and what age required for these two types of RC car and RC truck.

As a dad to racing sons, they become aware of serious racing at around 11-12 years old. By 16-17 they'll be completely rebuilding the chassis and moving onto engine rebuilds and clutches. Yes, there's a lot to learn and great fun sharing that time with young boys and girls too.

Consider clutches as they are an essential aspect to Nitro (Racing Fuel - Methanol+Nitromethane+Oil) racing. On road we also have two speed transmissions (yet another clutch) to tune and it takes a lot of "dads" commitment to get it all together.

Many would love to come into this thread and tell you to buy electric, it's easier!! In truth, all RC racing is difficult at the best of times, just getting your radio, electronics, servos and remote gear is a challenge.

It's not cheap...! Nor is anything that operates at this performance level! It takes a lot of commitment, support and maintenance to keep them going nicely.

I'd suggest heading to local hobby shop, asking about a good 1/8th 4WD buggy and basic starter pack. Pullstart engine, glow starter, tuning screwdriver, fuel bottle and cross wrench for plug and wheel nuts... Try and get a good radio and servo deal.

You can dis-assemble and you should! While pulling it down, migrate to HEX screws and that's where I'd stop spending, don't hop up, just fix as cheaply as you can. Buy one extra set of offroad tyres, for off-road only) and use the worn set on the street and have some fun annoying the neighbours getting some free practice at home. Keep the entire track in full view and stand back if not.

If you can keep it running for a year (there'll be breakage), hang out at a track or join a club, then you'll know what to do. If you crash and burn on the first day and persist, I hope the local hobby shop sorts it out and lessons learned. (there's heaps of things that go wrong that you would never have expected, just finishing is a challenge of it's own)

Losi are good, so too the Kyosho Inferno, plenty of good ones to burn your fingers on and they all get dirty!

good luck.
