So I'm gonna take a guess and say that I can convert a blender into an rc car. Sounds pretty straight forward if you think about it. Powerful motor in blender stripped down laid horizontally paired to pulley or something. i am open to any suggestions. Is this a good idea?

You'll need a veeeeeeeeeeeeeeeeeeeeeeeeeery long extension cord to power the ex blender motor...

Have you considered using off-the-shelf RC components which ave been honed over the years to fit the purpose?

My idea solder the blender motor to a power source like a battery that would sit on the rc

Afaik a blender motor is AC powered. You'll need a DC/AC converter with sufficient output voltage and power to operate the motor.

A blender will need ~ 500 W (give or take some).
Suppose you have a 12 V battery and an ideal converter (note that no ideal converter exists, add 10 %... 20 % losses for the converter). 500 W from 12 V means 42 A (rounded). You'll need a 14 Ah battery to run the car for 20 minutes.

A brushles RC motor can be had at e.g. up to 700 W top power, will weigh less than the blender's motor and RC speed control is readily available.
Plus all the other gear you'll need to control the RC car.
Minus the risk of dealing with potentially lethal voltages as required by the blender motor.

Good point but I am just interested in making it work not how effeciant it is

you realise it will be a big and heavy battery ... eg a car battery ?
what physical size did you expect your RC car to be ?

Others have pointed out the impracticalities, but if you're determined to use a blender motor post the spec of the motor (voltage/current/power/frequency ratings).

I think I will build an RC car with a steam engine. Does anybody know how large he water tank will have to be?

Why use water? Use liquid air, then you will not need an additional source of heat to generate 'steam'. The thermal energy from the ambient will suffice, provided your heat exchanger is big enough.

This is my first post, hi everyone.

So, I would like to do the opposite. I have a stick blender I love and this being the second time in 2 years the motor has died, I'm attempting to put a brushless one in there. I found a replacement the first time it happened for the entire handle and motor section and seeing as my search throughout the internet seems to say they don't use brushless motors in blenders... Which is what I wanted to buy, seeing as no replacements are found now and I want something that's going to last longer than a pet fucking octopus!

ANNNYWAY... Any advice would be appreciated. I've never done any rc car stuff but the electrics of this seem to be within my abilities to bodge together. The only unknown is what the power rating of the motor I'd actually need would be. I'm aiming for overkill... Y'know, if I'm guna go to the trouble of fitting the whole thing myself!
