It largely depends on the specific type of RC car model you have. Electric RC cars don't create much noise especially the ones with brushless motors. They are a perfect option to go if you want your car to be environment-friendly as well as a remote control car that won't disturb your neighbours. Gas-powered or nitro-powered RC cars create much more noise in comparison. They also have more power and speed.
Hope that helps.
It really depends on the RC Helicopter. I had a very small helicopter that made very little noise, but my new (and significantly larger) RC copter makes a fair amount of noise. Most RC Helicopter make a buzzing sort of noise, that is reasonably loud. The volume depends on the size, how high it is going, how fast, and what manoeuvres.
A test to measure the noise level of the exhaust system.
It's the power steering pump. Check the fluid level. You might have to replace the pump.

The noise level distance formula calculates the distance between two points based on their noise levels. It is typically represented as: Distance ((Noise level 1 - Noise level 2)2).
The sound level of the noise measured at 42 dB is considered moderate and is similar to the noise level of a quiet library.
To determine the level of noise in a circuit using a Johnson noise calculator, you need to input the resistance and temperature of the circuit into the calculator. The calculator will then provide you with the Johnson noise voltage, which represents the level of noise in the circuit.

A resonator on any car is to help the muffler keep the exhaust noise level to a minimun.
Check the power steering fluid level. It might just be low or there is a leak.
could be the fluid level is low
