Converting an R/C car into single-rotor drone?!

[ClobberXD]

I've got an R/C car that doesn't do good... Can I just remove the plastic chassis, and wheels, and then fix a rotor to the rear axle (one side), to have a functioning drone? The front axle can be used for left/right flaps...

I think you under estimate what it takes to make a drone fly. An RC car is not going to cut it.

 

And flaps are useless on a helicopter. you also need another rotor to counter the torque from the back wheel, and a stabilizing force to direct lift. 

 

A three channel radio is not even enough to fly a plane with (technically you could do it though)

[Enderman]

no

thats called a helicopter

 

and you require very advanced engineering design to make anything that gets off the ground

[manikyath]

in theory you can.

 

in practisce, you need a degree in aerodynamic engineering and probably a few years of experience with aircraft.

the motors for RC cars probably arent made for low torque, high speed situations that are meant to be used for propellers

and then theres aerodynamics

and keeping the aircraft from tilting, spinning, and turning without control requires sensors and a microcontroller

 

simply speaking, its not as cut dry as just attaching rotors to the end of the car

in theory you cant, the way he described it

the motor and gearbox in an RC car are not powerful enough to lift it with a rotor

Are the motors that weak? So shall I drop this project from my precious agenda?

some RC cars.. i beg to differ.

 

but yeah, most likely not gonna happen.

they are not weak

they are different

rc car motors are much lower higher kV and spin at higher RPM

they are supposed to have high acceleration and speed, not massive torque required to spin a 36" blade (yeah, you would need 36" blade to lift the weight of a regular 1/10 rc car)

there is no RC car that has the required mechanics to fly by directly attaching a rotor to the drive shaft

its simply not possible, unless for some reason your RC car has a plane/heli motor in it, which would be ridiculous, cause rc cars are meant to go fast not slow

it'd come down to prop design, but if OP has to ask, he's probably not up to the task, because if he was he'd most likely be working at noctua
