This page will give you information on how to build a model car withhydraulics. We are going to give you step-by-step instructions on how tocreate the model.  We are also providing you with questions and answersat the bottom of this page.  If you don't see your questions listedbelow please email us at royalindividuals@yahoo.com

In this demonstration we are going to work on the all famous 1964Chevy Impala. This is going to take a lot of patience, so be ready. Beforewe can get started, we need to make sure that we have all the materialready. (Click here for the material that you need)
 
 

First we cut the front A-arms and rear axle about 1/4" wide , afterit is cut, we must make sure that the edges are smooth, so we take a fileand smooth them out to a nice clean finish (clickhere to see an image)

Now we are going to install the "guide line". we are going to usea small paper clip for a guide line. you want to cut a small round holejust big enough to fit the paper clip on the chassis, we are goingto install 2 guide lines, one on the front wheel wells and one on the backwheel wells. Make sure that you put the guide line in the correct place,if not you will have problems later. (click herefor image)

After this is done you must provide the T-sliders and the O's. You can make these yourself or you can purchase them.  It is verycritical that these T-sliders are made perfect because this is the partthat makes the car maneuver around smoothly and is very critical when yourdoing side-to-side. For a person that has little or no experience, I wouldrecommend you purchase these from a hobby shop that deals with Lowridermodel cars and accessories. The O's must be glued to the chassis on thefront and rear axle, where the cuts were made. (Clickhere to see an image of t-squares) (Click hereto see position of the t-squares)

We are going to be using small motors that can be purchased at alocal electronic store or at your local hobby shop.  You can be creativewith the mounting of the motors, this example shows the motors in a verycommon way of installation. Mount the motors as shown in the diagram. (clickhere to see an image)

When you mount the motor, make sure that the body will fit on thechassis with the motors in place, so before you glue or tie the motors doa "body check" by taking the body and putting it over the chassis withthe motors in, to make sure that the motors are not sticking too far outto give clearance to the body.

You have to make sure that the motors are held down very solid onthe chassis. For this, some people use hot glue to glue the motors on thechassis....i would recommend that you tie the motors to the chassis usinga small, but strong string for example fishing wire, and also using a littlebit of hot glue to secure the motors, this will prevent the motors fromcoming off when the car is in movement.

Now we are ready to install the the hopper wire. For this we aregoing to use 20LBS fishing wire that you can purchase at a local fishingstore. we are going to cut an 8 inch wire and make a knot to one of theends on that 8 inch hopping wire and insert it into the T-square whereyou made a the hole at the top and using a small connector to connect tothe corresponding motor.  (click here to seean image)
We need do to this on all four motors.

Now that you have the motors in place with all the hopping stringin place, it is always suggested that you try each individual motor tomake sure that it will go up and down smoothly and will not get stuck inthe up and down action.....

We are going to use small 4x2x2 hobby box tomount the switches. We are going to be using 4 dpd momentary toggle switches.You want to make sure that the holes are drilled accordingly and accurateonto the switch box, if this is not done, then the switches will not lineup, they have to be straight.

We are going to work with a 2ft-5wire phonecable that you can purchase at your local hardware store or anywhere theysell phones. You can use a 6 wire or an 8 wire cable if you cant find a5 wire cable in your area, you are just not going to use some wires

Now that the switches are in their proper position,we can start soldering the "power bar" you can use a paper clip as a powerbar, you must solder the power bar to the middle prongs on all 4 switches. now that the power bar is in place you can solder a wire from the powerbar to the positive lead on the battery. We are going to use the blackwire on the 5 wire cable. which leaves us with 4 wires.  ( clickhere for image)
 

Now we are going to solder all the motors'snegative wires to each other, so we wont have to work with a lot wires.once these wires are soldered, we will run a wire from one of the motorsnegative lead, to the negative lead on the battery. (clickhere for an image)

All the wires on the cable should be all differentcolors. so solder one color wire to each positive lead on the motors. weare going to connect the red color wire to the front-left motor, we aregoing to connect the green color wire to the front-right motor, and theorange color wire to the back-left motor, and the blue color wire connectedto the back-right motor. But the color wire really doesn't matter as longas you remember which color wire goes to which motor. (clickhere for an image)

Now you should have all the motors negativeand positive leads soldered, its time to connect the wires to the switches.we are going to connect the red wire to the top 1st prong on the 1st switch,we are going to connect the green wire to the top 2nd prong on the 1stswitch, we are going to connect the orange wire to the top 1st prong onthe 2nd switch,  and we are going to connect the blue wire to thetop 2nd prong on the 2nd switch.  (clickhere for an image)

Now were are going to add jumper wires whichwill let us control 2 motors at the same time with one switch. were aregoing to need eight 8 inch wires for the jumper wires and connect them asshown in the diagram. (click here for the diagram)

Now we are going to add more jumper wires tothe existing jumper wires for more switch action. Now remember the diagramonly shows the new jumper wires that you are going to solder on. solderthe new jumper wires as shown in the diagram. (clickhere for diagram)

After this is done, you are ready to put theswitches in the switch box.  Before you put the switches in the box,make sure that all the soldered wire is covered with electrical tape, thiswill prevent from any electrical problems. now you can screw the switcheson with the screws provided with the switch box...............

Remember, Only try to use the model in a periodof 5-6 minutes at a time and give it a 10-15 minute rest. You want to dothis because the motors get very hot and if you use the model for a longperiod of time, it could cause the motors to blow out, and you will haveto replace the motor.
 

1. why does the model get stuck sometimes whenthe car is in the up and down motion?
Answer: make sure that you have just enoughhopping wire going to the motor, you don't want to make it too tight ortoo loose. Also make sure that the connection from the motor to the stringis not all the way in the motor. and you want to make sure that the stringis not rubbing on the chassis.

2.why do i hear a buzzing sound when i hita switch
Answer: when you hear this, it means thatthe hopping wire is no longer connected to
T-square or vice-versa, all you have to dois put a new hopping string, you will see that this is something that youwill have to do frequently so get used to it.

3. As soon as i connect the wires to the battery, the motors are activated and the car
stays up and will not come down utile i takethe power off. why is that?
Answer: when this happens, it means that there are some wires inside the switch box touching each other witch is causingthis, make sure that no wire are touching each other in the switch boxand make sure that none of the jumper wires are touching another switch

4.Why can't i get 3wheel action?
Answer: in order to get 3wheel action youmust have some weight in the back of the car, i would recommend using afishing weight to get the proper weight in the back
