Specs:
(1) buy a breadboard starter kit, battery/power supply, audio sockets, 10K, 100K, 1M potentiometers, a set of leaded resistors and capacitors, and a few diodes.
e.g. something like this: https://www.amazon.co.uk/ELEGOO-Electronics-Potentiometer-tie-points-Breadboard/dp/B01LZRV539/ will provide most of what you need.
You'll need to buy potentiometers as well. e.g. http://futurlec.com/PotRot.shtml
(2) buy a few CD40106 "Hex Schmitt triggers" - these are the core of your square wave oscillators. Each chip gives you 6 oscillators. More than enough for a drone.

They are common and cheap, and you can run them from 3V to 18V (absolute maximum)
(3) Read and build this http://www.fluxmonkey.com/electronoize/40106Oscillator.htm, and that will start you off.
(4) Start addings LEDs to the outputs of your oscillators so you can see what's happening in your circuit.
(5) Advanced: learn how to use op-amps, so you can do proper mixing, low/high pass filters, etc. These are usually "cookbook" circuits. Just learn how to make a few, and repeat them.
If you are willing to wait for shipping you can get similar things a lot cheaper from china:
They all vary in what sensors they include and can take weeks to ship but for the price these can be better value.
Whether they are worth it or not in another matter - you will not likely use 90% of the components in them and can simply buy the things you need a lot cheaper individually. In addition to this you quite often need more than the single sensor of a particular type that they come with so you normally end up needing to buy more separately regardless.
What they are good for is if you want to experiment with a large number of different sensors or want a collection of them for random projects in the future and don't want to wait for shipping to prototype something in the future.
It might be better to start with a general electronics starter kit rather than a sensor kit (ie one that comes with basic components like resistors, caps, button, leds etc) as these are good for a variety of projects and the parts that come in kits like this are often bought in larger quantities or more expensive when bought separately and are generally more useful to a wider range of projects (when combine with specific sensors that you can buy separately). Such as:
