i got this chinese car from a local i want to make it go faster but it has a radio reciever in it the car is 6v but i want to keep the reciever in there and make it go faster do i need a new dual motor controller in there to handle the volts or will it be ok 6 to 12 isnt that much is it and why does changing the voltage to 12 increase speed isnt that a gearing or current ratio also i want two gearboxes but i was reading another forum and it said to get new gear boxes the chinese ones arent going to be able to take the abuse if i get it going faster
what is my best bet on making this car faster and keeping a radio controller in there i have money but i dont want to spend to much on this little car

Going to 12V makes the motors spin twice as fast, and also increases their torque output. The gearing can make a difference in speed, but the voltage is where the real power is.
When going to 12V it's always best to put in a second motor and gearbox, otherwise the traction is going to be pathetic with only one wheel drive. Those gearboxes will probably take 12V ok.
The issus is going to be the RC electronics like you said. 12V may fry them. If there's a way you can isolate the RC stuff and wire it so only 6V goes to that and 12V gets to the motors then that's the way to go. |

| Keep the 6 volt setup...but utilize relays to activate the 12v going to the motors...the trick is finding a 6v relay.... |

i can fit three batteries in this car without cutting if i leave it a 6v and add the 2nd gear box and the 3 batteries will it go much faster or no if not then i think i have to just buy a new board because i dont know how to isolate the board with only 6v cause the board would have to get 12v because its rc the board opens and closes the cuircut so if its 12v it will have to have a new board but i dont know what im looking for i know that i only need a 2 channel remote but the dual motor driver has to be able to handle 12 volts can some one show me what i need i want to get as much power out of this as possably im going to have 3 12v 14ah batteries in this little car im willing to upgrade the motors but i have to keep this remote controlled
also i dont know much about rc but i only need two functions forward reverse, right and left is a motor driver rc by its self or does it need something else |

so i was looking at the rc motor controller it says 30A 240vac 5v
i dont know if it can handle 12v can it if not what do i need does a motor controller have rc capabilities already or does it need something else to make it remote controlled can you show me what i need
im going to attach another gearbox and motor assembly
i can fit two more batteries under the hood of the car will that effect the speed even if i stay at six volts to motors and three batteries has to make it go faster
i really want to max this thing out without tearing up the gearboxes |

I posted this for redoffroadyahoo he was trying to do something like that.
I would use 2 5 or 6 volt relays and 2 1N4004 diodes.
the relays should be SPDT Relay : (Single Pole Double Throw Relay) an electromagnetic switch, consist of a coil (terminals 85 & 86), 1 common terminal (30), 1 normally closed terminal (87a), and one normally open terminal (87).
Wire it up like below
the diodes make sure only one relay is actuated at a time.

Divinar find on the relay
do you have any pictures of the stearing? would like to see how they did that |

don't mean to hijack this thread, but i just picked up the same exact ride-on recently. from what i researched, the oem is chi lok bo (based out of china), and the initial importer was excalibur electronics who sold to several catalogs including hammacher schlemmer. support for this is essentially non-existent as are parts. are the parts axial bore sizes and gearboxes identical to 6v powerwheels? looks similar to peg, as well.
bflynfree were you going to use pw gearboxes? |

| no i found a gear box seller on ebay her email is atvofdallas@hotmail.com she sold it to me at 55 dollars that includes shipping and handling i wish i could have found gearboxes for less that would have worked but the ones i found totaled up to higher and they didnt have the mounting brackets built on so i just went with this cause it seemed easier than trying to retrofit different ones and the gearing is probably different i didnt want one wheel going faster or slower than the other |

The gearbox drives are specific to various chinese brands and PW gearboxes will not drive the wheels without a lot of modding (in other words, might as well add PW wheels as well if you decide to do it.) Your particular version is a really common one amongst chinese generics in terms of the driver. I have about 12 of them sitting around and about another 10 installed on vehicles around here. there are several variations of gearbox shape and output ratios. It's not difficult to source the right one, but a bit of care needs to be taken (or just buy a matching pair and turn your existing one into a spare).
Paying that much for one of those gearboxes is completely inconceivable to me. $5-10 including shipping is a more realistic amount. The GB's are very "fragile" mostly due to the smnaller than 500type motors and very iffy pinions (the plastic is not great and they are just superglued onto the motor shaft).
If you pop a wanted add up here you should get several replies for a gearbox and motor. Consider upgrading the motors themselves to something like 550's with metal pinions. Again, motors can be sourced through this site quite handily.

i wish i would have thought of that earlier but im impatient so i ended up paying more i would like to know how much of an infulence 550s would have on this car
i plan on makeing molds of these gears so i can make them all aluminum it will take a little time but i think it will be worth it theyll be able to take much more abuse without stripping out |

Your drawing will not work and the DPDT relay you have will not work ether, you need two independent SPDT 6v relays rated at 30a or higher and two diodes rated at 1a or higher. Follow the drawing posted by mxl4729, but where it reads "6v from control board" It should read "to original motor wires" that drawing will work and give you forward and reverse.

| it turns out that wont work either i found out how i need to do it but i have to take to peices of wire off the control board and im afraid of ruining it |

I'll try to take some macro shots later but the blue boxes are relays not rc controllers, you can look up the specs in English on helishun's website. The actual radio
circuitry already appears isolated ( track the black ic and long antenna wire); the relays appear to be wired to the main motor and front lights respectively. the front servo uses a much smaller motor/voltage and also looks to be isolated.
Now assuming resistance stays the same, doubling the voltage is another way of saying doubling the amp/current since the main motor will still effectively operate at 6v. So I would be way concern about these motors holding up, the isolating cicuitry issue seems already taken care by the manufacturer.

here are the macro pics:
power module
60.99 KB
main board
98.78 KB
total of 4 relays (each seems to have a corresponding diode ie the little black cylinders); 2 on the power module and 2 on the main board. This matches the number of outputs; 6 V main motor, 6 V headlights, <6V front servo, and <6v RC.
The smallest rated relay is on seems to be the power module and is rated at 10A 24VDC; does this mean that by conservative estimates, as long as this is not exceeded the RC should be ok? I think that is a reasonable assumption. By Ohm's law, this is equivalent to 20A, 12VDC; which should be good enough for 1 motor juiced with a 12 V battery? someone please correct me if I am wrong; freshman physics was a long time ago.
By the way, the RC circuitry largely seems to consists of the IC and antenna in the lower left corner of the main board.

| the main board in your pic carfu looks just like mine but i dont have the slightest clue were they would have hid that power board and ive nearly taken this whole car apart |

| Wasnt hidden on mine, was tacked up next to the main board and between the battery and main board, could have been left out on the non excalibur models for cost cutting basically protects the rc from what I can figure. the main relays drive the motor and headlight. |

| WOW- I have the same car in silver and I am looking to do the same thing. Except, everything you guys mentioned was like a foreign language! If this is all figured out already, could someone please tell me what they did? I would just take that direction to the hobby shop and pay them to do it all. This thing on its own is WAYYY too slow for my daughter. Please let me know if this project was complete. If any of you want to pick the project up, I can send the car over to you.. Thanks |
