    We now join a build already in progress.

    This is a 1972 AMC Matador sedan black & white 'Adam 12'. Originally built by Cox as a gas powered free-run car with interchangable steering cams that made it drive patterns.

    She may not be the new Bluesmobile, but it's going to work out ok. Missing 2 headlight lenses, and a lightbar lens. I think i can work aound that... I wasn't around when these were, so i'm going to need some help on lighting patterns. I grew up mostly with CrownVics with a red/blue lightbar up to the current lumen-wars nightblindness causing dangerous walls of light. Headlights, tail lights, marker lights are easy. May even do turnsignals. Roof lights do i want wig-wag or both on independant flashers? Do i want headlight high beams to wigwag opposite roof, or were they not doing that yet? Do i want tail lights to wigwag, or was that not happening yet either? Powering the back is my one issue i haven't figured out. Original axle is plastic 1/4" hex between the wheels, and had a huge tooth spiralcut gear

    Doing some really important work on this... No, not ordering servos, a speed control, an rx, a battery, a rear end, or a sound thing, not even buying paint.

    Bore lens mount into passthrough holes for led, make intersecting tiny hole from base into light base. Grab magnet wire, (mine came from a stock jeep speaker) scrape ends and tin. Poke through tiny hole and out a big hole. Grab a red and yellow 3mm LED, file off the rim at base, trim short - leads for approx 1/2" oal. Solder short leads together. Take long leads + trim shorter, then put around 45 deg angle. Tack onto magnet wire, mark car side of wire with sharpie or something. I did Black to ground, red to red light, no mark for yellow. Test. Put new LED pokey-bit assembly into the modified pokey-bit receptical. Test again. Don't be like me and not test the red side until it's assembled, then realize its bad. By now it works, and you fully remember why you don't like magnet wire, and try to hype yourself up for round 2.

    Little later i have exhausted the swear words i know. I need to learn more languages...
    Let's back up to how i could have gotten what actually worked 'the easy way'. I pulled the lens out, turned the lens pin mount into a through-hole, then up sized it to fit a 3mm Led with the flange filed off. Then one side got up-sized again to about 2/3 or 3/4 depth so it's past the next hole we drill. I drilled a 0.028" hole up through the base intersecting the through hole for leds, then passed 3 strands of 0.005 magnet wire in tiny hole base, and used a stick to push wire out the big side of through hole. Then scrape some enamel and tim end of wire, attach, test, install, test.

    Red has the oversize holes, not too awful, but looks like i'll probably need to do a lens

    Let's try , 1 adam 12, code 3
    [​IMG]
    And lo there was light.
    [​IMG]
    I'm not sure if i need to put in High beam headlights instead of the stock lenses so it all matches
    [​IMG]
    Or i could try to make a filler lens that sorta looks like the inboard ones. Or i could say meh, it's good.

    Litte bit later
    [​IMG]
    More lights
    [​IMG]

    The round lens of the LEDs were filed down to fit in blind holes behind the body lenses. I smoked several leds trying to get it all working, ran out. Hope i don't get pulled over...
    I think i might have enough lights now. Next up is going to be building light controls.

    Then something about a radio control car...

    First let's try get our new apex preditor used to its new habitat... A truck and construction meet!

    Somehow my bus was 'deemed suspicious'... i think it was profiling.

    Anyway, got some junk machined into unobtanium to mate toy grade junk to obsolete junk.

    Brass plate ties a toygrade gearbox into chassis. Nothing very fancy yet.

    Also drilled out the broken roof antenna, installed 30lb fishing line for better whip antenna
    Put some electronics on in a rather sketchy manner.

    "This black & white patrol car has an overhead valve V8 engine producing 328 hp at 4800 rpm, it accelerates from 0-60 in 7 seconds and has a top speed of 120 mph..."

    I got the headlights circuit working remote on a hacked servoboard, then hotglue mounted light wiring to body, cut wiring to size, retermed. Didn't have the right parts to remote activate the take-down lights, it's not Pursuit day.

    1adam12, 1adam12 vehicle accident with roll-over, entrapment.

    An awesome looking brushfire rig responded with me. (Sure wish there were an ambulance available too, but that was still on the workbench...)

    I think this might become my siren.

    What else might an early '70s police car pull over?

    Little while later it's time to go on patrol again.

    Control, 1-Adam-12, back in service.
    Ok so i let my ambulance steal the show in those pics. it's got a more impressive lighting setup, and since i run both of them from the same transmitter i couldn't power up both recievers. Besides the ambulance may need to leave in a hurry, while Adam-12 would be out of service on the scene until the incident was over and paperwork was done.

    At one point there was a police chase involving a blue Semi that was going on a rampage. The chase ended without incident when the perpitrators father took the transmitter away from him and took him into custody.

    The whole time i've had the car, I'd been bummed about the ruined white paint, but i found out Iso-alcohol got the old gas schmoo cleaned off pretty easily.
    [​IMG]

    So in celebration, it got chromed wiper arms. Then since the best looking cop car wheel setup for a Black&White is and has always been black steelies with dogbowls/babymoons and beauty rings, i added the set of chrome rings.
    [​IMG]

    I knocked together a rear 'strut-tower brace', which is more of a rear body support and package tray visible through the back window. I'm probably going to punch the on/off switch up through it, if i can find some kind of 'cop junk' like a hat or gun to make into a switch hider. It's not a cage car, so i'm not worried about the detained getting a hold of stuff.

    Yes i know the actual 1-Adam-12 Matador didn't run beauty rings on the steelies. They also ran the black 727 can lights so it didn't reflect cameras, and didn't have LED lighting. Eh, my car.

    I shared this car over on the 'Cox engine forum' since it started life as a Cox product. Somebody liked the bus, so here's many VWs.

    I'd finally ordered some sirens from Evan Designs. I'm happy to be able to know for sure the "9v" option works great off a 7.2 stick pack. I then put it on 4.5 - 6v rx voltage, works great! It will still take an RX Switch and a Servo to run the Police siren fully remote.
    It has a momentary button to toggle sirens, Adam 12 can use the siren in mode 2 or 4. All the sounds in sequence (1) and phaser (3) just don't fit early 70s american cops.
    A 'Police siren' will also be getting installed in the Econoline Ambulance, all sounds will work without it being too weird for that vehicle.

    I'm calling it close enough to a Federal Signal PA20A.


    I also really like their Fire Siren, it's a great Federal-Q that winds up nicely but doesn't really free-roll down, (so i think it's a Federal QE) Also they're a little heavy on the Grover airhorns, but they atleast use them well instead of the stupid 'fuhfuhfuhfuhfuh' junk that my local dept seems to like doing. Guess i'm going to be really pushy on the way to the scene. I'll definately need one for my American LaFrance project later, probably with the bigger speakers. Screaming Q!!!

    I like wires...
    [​IMG]
    Here's the wire harness it takes to run the body lights. The roof lights are still currently setup as only solid instead of Red solid / Amber wig-wag.
    Then i still have to knock together a servo mount for the momentary switch. Need to pick up some white paint for touch up, then chrome out the window trim.

    Although i never even ran her on nitro, i have to admit the cox cam-steering cars weren't really all that amazing. It was cool that it's a robotic car that worked off a rotary punch card. Electric RC is *SO* much better than on Nitro with 4 interchangible steering control disks. Action van Matador stock-car racer
    Some sick part of me still really wants to build up an Action Van body. It just needs graphics and murals to go full on 1970s Vanning.

    Chassis layout. Siren is a black chip, speaker, push button. It now has its own control servo since i wasn't feeling like trying to make a control circuit. Power tapped off the RX bus with 2 pin servo lead. Knocked together a styrene switch holder, bonded to servo case, set the epa to lightly go clicky. Toggle switch D down/up to advance through settings On/off switch is mounted in the package tray. Fwd is on.
    Body lights on th channel, up is on Roof lights on sw B, down is on. This way car turns on dark, light controls come together for On

    The spring on the crankshaft starter knob is a worm gear for the spur gear that floated on the original hex axle, a switch let you mesh or clutch the engine --

    I kinda think i may deviate from screen accurate with the roof lights. Adam 12 had the Reds turn on solid, with wigway ambers, but now days wig-wag is better understood and is a whole lot better at getting attention.

    Electric Adam 12 was entered in a contest over on its original engine forum. Figured i needed to show off the features I kept the speed backed way down, my cameraman isn't used to working with rc cars.

    Bad videos of a kinda cool car.




    Yes i know i need a video editor. I'm open to suggestions!

    I got 3rd place out of 6 in their Modified class
