    what you have in there is most likely oil and not fuel because the fuel used for these cars would never dry up and leave a residue it would just evaporate off completely.

    oh, well, in that case I change my question to "how on earth do I get that oil out of there"

    The fuel kinda worked but it's slow, the fuel was transparent but after bathing the engine in there for 1.5 days it turned yellow and it has a lot of gunk floating around in it.

    I'm now testing break cleaner, let's  hope that removes it quicker.

    Soak it in isopropyl alcohol. Then wash it with hot water and soap.

    Soaking it in fuel should also work. 

    I tried bathing it in fuel last night, it has been in there for over 12hours. it kinda worked, a lot of the dry fuel dissolved, but not all.

    Shall I put it back in the fuel for another 12hours or shall I try isopropyl alcohol?

    Doesn't rc cars use methanol, nitromethan and normal gas?

    Pipe cleaner (mechanical cleaning) and ATA paired with ice  (if it does not damage anything) as a first step and after this try organic solvents. Water won't do it. Things like hexan might work.

    someone gave me the advice to just bathe it in the fuel overnight, it has been in there for a few hours now. if that doesn't work, I'll try your methods. I'll keep you updated!

  4. I'm working on an on RC car which runs on liquid fuel, but I ran into a problem: the fuel that was left in the engine block dried up completely.

    Does anyone know how to get the fuel out of the engine? (without breaking it) Is there some liquid I can use to dissolve the fuel?

     

    big think: the engine

    small round thing: should go on top of engine

    2 things on the left: heatsinks

  5. Does java editor 15.22 have some kind of config where you can change the default syntax for the uml class editor. in the uml editor you can give a class attributes and automatically create set and get functions, but I don't really like the syntax of the set functions, the get functions are exactly the same as I would do but the set function are not.

     

    What I want:

    public void set_name(String new_name) {
      this._name = new_name;
    }

    What I get:

    public void set_name(String _nameNew) {
      _name = _nameNew;
    }

     

    Is it possible to tell the editor to generate the functions different?

    However, it shows the greatest purchase of each day, instead of the sum.

    I tried to remake your table with graph, it doesn't show the greatest, it shows both, but on top of each other both starting from 0 where one goes to 25 and one to 5.50.

    I haven't found a way to show the sum yet, I'll try some more methods and tell you when I find something useful.

  7. actually, a lot of freezers are made like that, but the standing fridges/freezers take less floor space, so its easier to place in a kitchen. I know multiple people who have a freezer like a mc chest in their garage and a 'normal' fridge in their kitchen.

    Not really. I'm going to use an arraylist here just in case you don't know how many elements will be created.

    
    List<Duck> ducks = new ArrayList<Duck>();
    for(int i; i>whatever; i++){
      ducks.add(new Duck());
    }

     

    ahh, ok, thank you!

    I'll try to use it and learn a bit more about arrayLists
