Question What is the recipe to build a hobby-grade BMW police car in 1/15 to 1/20 scale?

here are my specifications:

1. proportioned steering and speed control:
good low-speed control for parking and backing up
2. forward and reverse
3. working body lights with neat flashing police lights in the grille, etc.
4. working light bar
5. working alley lights
6. working siren
7. blacked-out windows
8. authentic scale body
9. authentic police push bumper in front
10. a 4-door sedan BMW body as a 3 or 5 series
11. functional differential and suspension
12. street/touring tires (no drift tires)
13. authentic ride height
14. dual exterior mirrors
15. chrome grille and wheels

Can a two-channel radio turn the siren and specialized police lights
on or off or would I need more channels?

What is a good kit that would serve as a platform for my build?
I prefer NiMH battery technology.

This car is to be an electric on-road city-slick vehicle with wheels
under the fenders and not an open-wheel buggy nor truggy .

Electric is the way to fly. No mess. No noise. No fuel expense.
No pollution. Easy to start. Easy to maintain. Indoor-compatible.

XMods are your best option for that. Not many other micro RC cars exist. Maybe a Mini-Z if you're feeling rich, lol.

I don't want to go any smaller than 1/20 scale.

I might set my sights on something as large as 1/10 scale if that is very doable.
It seems as there is a lot more readily available in 1/10 as that seems to be
the definitive standard of RC.

What does "doable" mean in terms of the RC hobby?

1. there are kits and aftermarket parts readily available on the market to do what I am thinking about doing
2. the project won't be so overwhelming as to be above my financial means or skills as a DIY craftsman

You are probably going to have to go 1/10 scale. There you have tons of chassis and body options. And yes you will need more than two channels if you want radio control for more than throttle/brake and steering.

I'm sure you can find someone who makes 1/10 scale light bars and other police accessories, and check out HPI for bodies, and they have good 1/10 and 1/12 scale chassis' as well, probably have a BMW that.

Also look at Tamiya products. As far as doable, in the 10/ scale range what you want is quite realistic whether you find some premade parts or make some custom stuff. You're basically looking at a custom body and simple electrical work, the rest is cosmetic and it depends on how real you want it to look.

You might be able to get a toy grade R/C police car, and use that body and electronics on a hobby grade chassis, that's where I would look first, though off you only want BMW it might be a stretch to find, I'm sure there are R/C police car toys out there.
