Hi Shakey
Best of luck with the project
It does sound very ambitious to do all that to a high standard. There's so much else for students to do in their A2 year, I hope you haven't let yourself in for too much work!

DM has already pointed out, model railway controllers and slot car controllers are quite different things.
Not sure what you mean about 12 Volt setting and a 16 Volt setting on the transformer. In slot cars controllers and power supply are separate.
For sure it'll be a challenge to produce a product that does two rather different things.

Hi Shakey
Hope I'm not being to picky with this, but there can be extra marks for coursework in making it clear.

When you say it will be powered by radio frequencies I guess you are saying it will be controlled by radio frequencies, but powered by batteries (which is how electric RC cars work) - or in the case of slot cars pick up power from rails either side of the slot.
It is possible to power cars by radio frequencies, but there are serious safety and regulatory issues in doing that.
