Got my old bandit out the other day. The battery was shot so ordered some new ones. Charged it up and it would only turn one way and not reset without moving the wheels by hand. So I took it apart seeing if it was a contact problem, dirt etc. Anyways I wiped the buildup off the green circuit board inside of the (part pictured below). Now the motor spins out of control as soon as you plug the battery back in. Any idea how to fix it? If not does anyone have a extra one of these parts they can sell? Will suck to rewire it but better then nothing. Wanted to play with it, with my 2 year old. She loved it going back in forth but not much fun it you can't turn ;) So any help would be great, thanks

Ive got several cars from the bandit chassis that have working electronics and I will be converting to hobby cars. I could sell you the complete electronics that way you can just drop them in and go.

Cool man let me know what you come up with.
I was talking with a friend and he dropped off a old Nikko truck thinking the parts might would work but there not even close, tires might work though for a upgrade. ;D

bandit king probaly has ya covered, but if not, i have a 49 mhz board and remote in case yours is 27, i may have a servo alone too, but not sure

Mine is a 49 mhz.
Got out my Tyco Indy car too, it's not quite as much fun as the bandit. Sit's way too low and can't drive it in the house as well.
-
if yours is 49 mhz, then i can only assume you have a red bandit or older baja bandit? post a pic either way but especially if ya got a red one

Nope it's black. It's in parts right now but I'll snap a pic here later and post.
-
Here is a pic of it apart. It needs cleaned up bad. Was going to do it yesterday but wife wanted it off kitchen table. Since i don't have parts to fix it yet might as well wait.
-
is the chrome bumper still in tact?
-
Yea it still has the chrome bumper.
I was looking at the pic, damn it's dirty. It sat on a shelf for probably a good 10 years before i boxed it up, and that was where it's been for the last 7 years.

no flat spots on the tires?

no flat spots on the tires?
Not that I noticed. I'll check them back out tonight.
-
i just thought if its been sitting for so long it might have some
-
they do seam to get flat spots in them, you will know right off when ya get it goin, it will bounce everywhere

Then if that's the case i'll say no. Because it didn't the little i drove it the other day.

Just checking to see if anybody has anything to help me out? Or a way to fix it?

hold tight, I have a perfect working radio in my wild thing hopper that I am going to be converting to a hobby car setup. I just ran a super hot motor in it and the speed control wont handle it so I will be taking the complete radio out.

Sorry, not presureing anyone, but after years of motorcycle "forums" & people saying "sure man got one" and then there never heard from again, sometimes you just have to refresh ;). Really no hurry weather sucks here, so can't get it outside anyways.
-
Well I got a new servo and it has the same problem. Any other ideas?
-
did you use the whole board/servo or only the servo? im assuming you used both? the board i sent you came from a working truck so id check the remote itself, i had one that the contacts was not making good connection when you turned, if you only tried swapping the servo, then id give the remote a try and then swap the board
-
I just did the servo, less wires to splice. Some of the wires on the board where coming off so I'd have to resolder quite a few to even test it. Not sure if it happened in shipping or what, but at least 3 are barly holding on.
I took the remote apart and looked it over and messed around with it, there was a groove in the copper but even if i tried to move it out of there it was no luck.
Was really hoping to just swap the part and be on the way of driving it.
-
may have been my barbaric packing.........was on the spot and the plastic bag was all that was handy. anyhow, i bet the board in yours is bad since thats the most common thing ive seen to quit working is the servo, or usually reverse quits either one.
that board i sent you does function, probaly worth adding some solder too if the wires are loose.
-
I was hoping it was just the servo.
I really don't want to hack the crap out of mine since alot off your wires were cut off. But we'll wait and see what i do. Maybe someone has a no hacked board they want to sell.
-
I might have a board no promises but possibly. I know I have servos.

well if you already cut the servo loose from the board it was attached to, its already hacked, best thing to do is re solder the 2 battery and 2 motor wires that i had cut loose, and the lil red light is all that hooked to the smaller wires, a solder gun and shrink tube along with 15 minutes and its back in buisness. most likeley if you get another board, the battery wires will be cut in half to remove it from the truck chassis, so will the motors wires unless you get one with the motor included.
in any case if you decide to buy another board you need one from a baja bandit like yours or an older hopper with the old style rear dif like the one in your baja, since the motor is wired the opposit of the old vs newer bandits and other tycos, thats if you buy one with the motor included. the later tycos for some reason have the motors wired the opposit of the newer tycos and so the forward will be reverse and reverse will be forward, im pretty sure its because the difference in the way the gears are set up in the older/newer ones.
good luck, and oh yeah, i had a loose wire on a on off switch awhile back, i heated the tip of the solder gun then just touched it to the soldered joint long enuff to re melt the solder to the wire and it worked good, maybee do that to the loose wires on the board?
-
I haven't been able to touch this project, been super busy & I have a new baby due any day.
Anyone on forum willing to fix this problem for me if i can send it to you?
-
The motor is going to spin intill it reaches the contact loop which completes a continuty circut. You can test this , but u have to unsolder the violet, gray, white and blue wires from the board. If i where u, i wouldnt splice anything. Just re solder a new wire. So what if people say u hacked it, thats just silly talk if it fixes the problem. I fixed my Eliminator, i wouldnt call it hacking.

When I get a chance I'll look into this.
I just want the damn thing to work, it's only one little thing keeping me from enjoying it.

the drive motors or the sterring servo motor spins?
if its the servo tweeking out, seems like a wire is arching creating a pulse circuit. if theres a bed wire and its pulsaing it will cause the servo to tweek out.
if its the back motors then check around the 2 wires connected to the motors an board. make sure theres no dust buildup making contct with the 2 wires.
also touch the radio crystal and see if it wigles. have the car on so if it is that then it you will notice it with the glitching.
not sure if these ones are wax coated to prevent moisture? maybe some one can answer that for me
