spur b4

[stampede vxlboy]

does the spur gear make a noise b4 or should it be smooth ? any help plz . or do all buggy make noise from the spur gear ? :lol:

[chris_trcc]

all goes off dp size, but on a b4 should be quiet, sounds to me you havnt got enough clearance between the pinion and spur. or slightly too much (is it stripping the teeth?)

[bodgit]

You should also check the gap is consistant by rotating the spur one full rotation, and checking the gap. Not all spur gears are perfectly round so what may seem enough on one side may be tight on the other.
I use a bit of paper or insulation tape between the teeth when I set mine so it cant be too tight.

[chris_trcc]

i seen a few people that done that in the past but never actually tried it. does it work on 64 dp gears or just the 48dp

[rc_dan]

i use the paper trick. works every time with 48dp's

should work on 64 dp to, try it ? try a Rizla if not

[bodgit]

If you find paper too thick for the finer 64dp use tissue paper folded.

[stampede vxlboy]

WHAT SPUR GEARS ARE THEY 48DP OR 64DP :woot:

[gerbil]

b4 's are 48dp mate

[stampede vxlboy]

THANKS GIRBIL

[jim76]

i think you should fit the madrat spur and pads on it, that will make it run a bit quieter

[rc_dan]

madrat spur is socking !

[stampede vxlboy]

are you joking jim 76 the spur gears for the madrat are pants

[stampede vxlboy]

sorted the spur gear out. but when i hit the brakes it slow at the brakes coming on . using ezrun 5.5 could it be coz of the power of the motor .i need it to stop dead . i use the same set up in my son madrat and the brakes on that are fine but that a ezrun 9turn

you should be able to change the brakes with the setup card for the ezrun speed contol

[stampede vxlboy]

i have but it will not set like the madrat brakes the well fast . but is that because the motor been faster or not . 5.5turn b4 and the madrat 9turner

[Battle_axe]

it could just be that you are going allot faster than the 9 turner and u need further to stop

[stampede vxlboy]

it does not seem it was making a buzzing tune and rev up on its own with out me touch the handset

[stampede vxlboy]

no the motor works fine in my son madrat the brakes are fast as hell . but in the b4 its like it takes 10 seconds to stop a little bit. but just rolls in the b4 like it does not want to stop . but the madrat rat as the same esc in a stop fast as hell in madrat but not the b4 . does anybody know why it would do this :confused::confused::(

[stampede vxlboy]

any help would be good

[i4n]

Are the rear wheel locking and the buggy just skidding to a stop? If so, that will explain why the B4 takes longer to stop (tyres have maximum braking traction just before they lock up and when they lock up they have less)

[stampede vxlboy]

when i hit the brakes it just carry on then stops about 10seconds after me putting the brakes on :confused::confused:

[i4n]

Simon, we know that - you've written it about 10 times in this thread and countless other times in the other thread you've started about the EZ run, but what you're asking can be interpreted in several different ways - do you actually mean it comes to a stop 10 seconds after you hit the brakes? Do you mean, it coasts for 10 seconds and then comes to a stop or do you mean it keeps accelerating and 10 seconds later it starts to brake and comes to a stop? Explain everything fully mate and we can help you as we know EXACTLY what is going on.

Anyhow, back to what I asked, are the rear wheels locking? Do they physically stop rotating but the buggy keeps going (like the skids you used to do on a bike when you were 12?).

If you answer the questions asked, it helps people rule out every cause of you problem. By doing this people will want to help you, rather than just getting annoyed with you asking the same thing over, and over, and over, and over.... For example, I'm using my own personal experience here by asking you that question as on my 2WD drive car, if the brakes are set too hard/high, the rear wheels lock up and it doesn't appear to stop.

[stampede vxlboy]

did you get my pm when you hit the brakes it just carry on

[i4n]

did you get my pm when you hit the brakes it just carry on

Yep, and replied to both of them.

[stampede vxlboy]

i have re set the diff and its still the same i put it down to the handset and esc that why the brakes come on a little bit and not full brakes ,

[bigred5765]

but didnt you say you had used the same hand set and esc on both cars and it works better in one car than the other??

[stampede vxlboy]

i have got a ezrun in the madrat 9t combo and a traxxas handset and in my b4 ezrun 5.5t and a traxxas handset set . and yes the both work better in the madrat :confused:

[stampede vxlboy]

it stop but no faster another plus brakes are set to 100%

[bigred5765]

if one is a 9t and the other a 5.5 its probabaly going faster so will take longer to stop

[stampede vxlboy]

i understand that but it like the brakes are crap on it
no because the 5.5 t work fine in the madrat brakes are very good

[i4n]

If you've done all I've recommended in the PM then it can only be the electronics, but as you say they work better in the Rat than the B4 I'm still thinking something is wrong with the car - it's the basics of fault finding, if you substitute equipment and the problem remains it is what hasn't changed at fault, in this case your B4. As others have said, it would be a lot easier if we could get our hands on the car so I'm afraid I'm all out of ideas Simon, I'd suggest taking it to a local model shop (with your radio gear etc), telling them what is happening and the let them sort it out.

For your future reference, here is a link to the .pdf version of the manual (2 seconds on Google looking for "Associated B4 Manual" found it) http://aedownloads.com/downloads/manuals/ftb4_manual.pdf download it, print it out and keep a copy with the car as it will answer loads of your questions.

[stampede vxlboy]

thanks i am going to set my 2.4ghz and see if that better . if not i will take it to the modelshop

[stampede vxlboy]

cannot get the back wheels to lock up at all . its does it in reverse

[Ashley]

Hi does your sons madrat stop all of a sudden?

Try drag brake on your b4 you will need to set that through the programming card though.

[stampede vxlboy]

the madrat stop dead and the b4 stop but know were as good as the madrat . and the spur are hard to set it right b4

[stampede vxlboy]

drag brakes on 20% and 100% brakes

[tony6187]

could it be the slipper being loose/worn pads?:confused:

[bigred5765]

cannot get the back wheels to lock up at all . its does it in reverse

so if it locks the wheels in reverse and not in forward driving,might it be the case Ur actually driving the car with revers as forwards and forwards as revers and u just revered your tranny to make it right, i read that some were if you change any two wires on the ezrun it reverses the direction of the motor???PS don't think any speedo has breaks in revers mode ??

[stampede vxlboy]

i set it all but the brakes are like that because of the power i have tryed turning the wires around and when you go forward on the handset it goes in reverse and when you go in reverse in forwards

[stampede vxlboy]

thanks for all the help guys hope to see you at a track soon

[bigred5765]

SWITCH THE TRANSMITTER TO SERVO REVERSE, IT SOUNDS LIKE WHAT I SAID ABOVE IS RIGHT THERE ARE NO BRAKES IN REVERSE,

[stampede vxlboy]

if i do that it will turn the wrong way

[bigred5765]

u can do it just on the throttle,

[stampede vxlboy]

i had decide to sell it i have seen something else i want.
its running fine now does it make the car slower if the grass is wet?

[jhammond]

Wet grass increases the drag, so yes, it would slow anything moving through it.

Why are you selling it if it's working fine? I assume it's working again because you listened to "bigred5765" and it was the throttle inverse that solved it?



Julius.

[stampede vxlboy]

no it was not the handset set its coz of the power of the motor

[Timee80]

sounded to me like it was just a loose slipper and this would also cause the noisey spur.

[jim76]

so you get a new car, set it up wrong, ask loads and loads of questions, possibly get it going ok, then decide to sell it.

why oh why does anyone bother to help you?! just get your next car from a shop, ask them for help so they can show you first hand.

[jhammond]

I'm in agreement.

This chap seems to pollute this forum with unnecessary topics; most of which have been heavily covered before.

[Col]

no it was not the handset set its coz of the power of the motor

Bullshit. I know a lad who tried a 3.5 in a b4 for a laugh. It stopped as well as anything alse I've ever seen.

[stampede vxlboy]

i have just tryed my mamba castler esc in it and it 10 times fast and the brakes work fast as hell but when you start of it start squrals when setting off i am not selling it know keeping it

[sparrow.2]

It squeals because you've built it wrong / your diff is still fooked

[stampede vxlboy]

why it fine with the ezrun but not as power full mambacastle
i have look on the manual and its how i did it

[stampede vxlboy]

could it be that the diff it too tight or the slipper is too tight

[jim76]

TAKE IT TO A SHOP OR CLUB!

[sparrow.2]

could it be that the diff it too tight or the slipper is too tight

Diffs and slippers only squeal if they are too loose.

Build both according to the manual using associated diff grease for the big balls and associated black grease for the thrust bearing (the little balls)

You can then even plop in a 3.5 turn and it won't squeal...

[stampede vxlboy]

i have took it to a shop the said it was down to the power its when you set off only

[sparrow.2]

Mate I've run a 4.5turn on carpet and driven it like a berk for fun and there wasn't the slightest sqeak from the gearbox. They are tough as nails!

[stampede vxlboy]

its fine with ezrun but not the mamba i would like to use the mamba as it is hell of alot faster

[ashleyb4]

More than likely you have a diff bearing out of line inside or its to loose. Or your slipper is to loose or your spur gear is melted or your slipper pads are melted.

A

[stampede vxlboy]

slipper no far from full tightened and the diff run fine with the cheap esc

[ashleyb4]

So you have taken the powerful brushless out and put the slower one back in to try to see if it still works??

A

[stampede vxlboy]

this sound fooked up but it fine with the ezrun and my traxxas vxl esc ? but make a funny noise with mamba

[stampede vxlboy]

no just tryed 2diffrent esc it and it work geat i am going to try my other ezruner esc in it know and see the diff must be ok coz it does not make a noise with any of the other esc i have tryed

[sparrow.2]

no just tryed 2diffrent esc it and it work geat i am going to try my other ezruner esc it it know and see the diff must be ok coz it does not make a noise with any of the other esc i have tryed


Next time your foot itches scratch your back...

[stampede vxlboy]

just tryed it with a diffrent ezrun and it fine brakes etc and the vxlesc hell of alot faster as well but there too big to use it in the car as they are big esc and the mamba make a noise but run fine in my traxxas rustler bandit vxl

[stampede vxlboy]

haha

[chris_trcc]

might be a daft question but have you got your slipper pads in the right way round ?, if it only makes the noise on the more powerful motor the slipper wont bite as good. you cant just tighten up your slipper to the max the buggy be horrible to drive around the track. check the diff again use plenty of greese on the diff get it running smoothly, other then that get your electronics sorted if you think its the problem. have you got any overheating problems?

[stampede vxlboy]

no heat problem at all but it only happens with the mamba but its 10 times fast with this esc.l but make a funny noise . and the vxl esc is fine works great brakes etc. but 1 of the ezrun slower than the other plus there no brakes on the other ezrun brakes there but takes a long time to slower down. i need to pull the brakes 10 seconds before i stop

[stampede vxlboy]

is the only 1 side you can put the slipper pads on or can you use both sides or not

[Dazzler]

is the only 1 side you can put the slipper pads on or can you use both sides or not

Slipper pads are one either side of the spur gear - You have implied by this comment that you are only fitting on one side only - I think this may well be the root to a lot of your problems. Try reading the manual !, it's all on line at the team associated site. Might save a lot of basic questions if you do, people will be guessing for a long time what is wrong, if you have built the car incorrectly and stated it is built properly.

100's of posts later, it apears unlikely there has been anything wrong with your motor, speed controller etc.

P.S. Your spur will most probably be ruined now...:woot:

[stampede vxlboy]

no there 2 slipper pads like all the other car etc and somebody said they go on 1 way instead of just put them on is there a special way for them to go on

[Dazzler]

########################READ THE MANUAL########################

The manual does not state that the slipper pads require fitting in any particular way round.

The manual is avaialble for download on the team associated site - it isn't here on oOple - go and look for it on the team associated site.:bored:

[stampede vxlboy]

i have read the manual from front to back .it was somebody else that said it not me . about the slipper pads

[chris_trcc]

sorry to say but the slipper pads indeed only go in one way lads. feel the surfaces of both sides of the slipper, you get a rough side and a slippy side. (You want it to bite on the rough side so put that on the out side so it rub against the plates. and just put a bit of greese on the slippy side and put it in place of the spur, stop it from falling out whilst building it back up as there pain in the ass to keep in place. stamp it sounds to me there nothing wrong with any of your spedo's just set up differnt to the transmitter. and also the modes like drag brake, full throttle, ect. reset them and follow the instructions and you be fine. if it takes 10secs to stop surly there no brakes at all!?, just rolling to a stop? that could be dangerous for you on the jumps and approaching corners

[chris_trcc]

also the manual might not state that because its common sense!! use your head

[stampede vxlboy]

i will try it got loads of solding to do. and got the do the diff again is the diff grease green in a little tube. but i will try it all out after tea thanks for the tips mate

[chris_trcc]

green? i cant remember as i just sold my b4 to go into 4wd buggys. diff greese is black? but also you have the clear stuff, not sure, im sure it wasnt green. somebody else will know and tell you. i may be new to the forum, may i ask why people got somthing against stamp? fair enough he posts alot because this is the easyiest place to get answers and tips. and saves him a trip down the model shop.

[i4n]

i will try it got loads of solding to do. and got the do the diff again is the diff grease green in a little tube. but i will try it all out after tea thanks for the tips mate

Green is the "snot" that you use for building shocks.

Transparent silicon is the stuff for on the diff balls.

Black stuff goes on the thrust bearing.

[stampede vxlboy]

thanks :thumbsup:

[chris_trcc]

have you sorted your buggy out? let us know how you get on mate

[bodgit]

no there 2 slipper pads like all the other car etc and somebody said they go on 1 way instead of just put them on is there a special way for them to go on

I remember someone posted that the slipper pads fit one way only on each side of the spur so stampy is correct

[stampede vxlboy]

there is no special way to put the slipper pads on. as long as there 2 slipper pads on 1 on each side it work . if that the case your the only person say it :confused::lol:

[PaulRotheram]

Sometimes there is a rough side and a smooth side.. this I think is the point trying to be made.

[chris_trcc]

trying to be made lol. what im trying to say is that yes, the slipper pads do go in both sides of the spur like it shows in the manual. but it dosnt show that the slipper pads should go in a certain way on both sides of the spur, rough side of the pads against the disc assembly. then you dont have to go mad tightning up the slipper

[bigred5765]

rubbish it truly makes no difference which way around you put them in the slipper, they are tightened down that tight that rough or smooth side as you put it will make no odds at all, and the moment it slips,and they always do they become smooth,its the alloy parts that need to be ruffed up from time to time,

[stampede vxlboy]

[chris_trcc]

cool, just thought this could of been his problem. but i still dont get you. so when the pads get worn, whats the point in buying new replacment ones, if its the alloy parts that needs to be done instead.

[Dazzler]

I would replace them if they were to get contaminated with grease / shock oil etc or if they were to be damaged when assembling the slipper, i.e you dont get them located correctly and tighten it up without noticing. You really should try not to get grease near the pads. When putting the slipper together, I'd turn the car on it's side and make gravity work in my favour rather than against me by having the car on it's wheels. The slipper will go together easy enough. And ultimately it will wear.

[stampede vxlboy]

i would not put grease on the slipper when you spin the back wheels should they spin free and start notching when it about to stop spinning .spin it by free hand

[chris_trcc]

where i put the greese is on the back of the slipper pad so wont affect the slipper at all, just makes life much easyier building together inbetween racing

[bigred5765]

where i put the greese is on the back of the slipper pad so wont affect the slipper at all, just makes life much easyier building together inbetween racing

if you put grease behind the pads when the slipper slips it gets hot,this will melt the grease and allows it to contaminate the pads then there screwed,even if you use heat resistant grease when it spins up it will fly out and contaminate the pads, the way to hold the slipper pads to the spur is use a very very small spot of super glue in one place to hold the pads to the spur,or as already mentioned use gravity and build it on its side,

[super__dan]

If a slipper is being used correctly then the pads glaze, this happens quite quickley but then stays consistent for a while. Eventually they glaze badly and then the stick/slip point will be inconsistent so time to rebuild. You can of course flip them but also if not bad you can recover them a few times by scraping the glaze off. I do this using a scalpel blade and scraping the glaze off on a flat hard surface.

Though hard anodized the plates do wear but at a slower rate, I use more slipper than than most and so change them once a year when my car gets a full rebuild. I'll have gone through a few sets of slipper pads in that time though.

I wouldn't ever put any kind of grease or oil anywhere near any parts of the slipper, just before assembling everything gets cleaner in brake cleaner so squeeky clean.

[stampede vxlboy]

SO DOES THE WHEELS START S NOTCHING WHEN YOU SPIN THEM BY FREE HAND WHEN THEY STOP SPINNING ITS LIKE IT START NOTCHINE WHEN IT STOPS SPINNING

[Northy]

Maybe :confused:

[Mike Hudson]

Sounds like a rare riddle to me does that...

[Dazzler]

SO DOES THE WHEELS START S NOTCHING WHEN YOU SPIN THEM BY FREE HAND WHEN THEY STOP SPINNING ITS LIKE IT START NOTCHINE WHEN IT STOPS SPINNING


Well, maybe it will, maybe it won't....

If you still have the motor fitted and pinion / spur meshed then you will see the 'Cogging' of the motor exagerated through the wheels.

The extent of this will be dependant on motor winds / type etc. Turn a motor by hand, you will feel the cogging effect caused by the magnetic fields.

If the motor / pinion is removed, then the transimission should be smooth.

[stampede vxlboy]

its fine when the pinion off but start doing it when i spin the wheels by hand that all but sound good when running it .but by hand it sounds like cogging when the wheels stop spin

[Dazzler]

its fine when the pinion off but start doing it when i spin the wheels by hand that all but sound good when running it .but by hand it sounds like cogging when the wheels stop spin

It's something you will see and feel more than hear, from what you have said, i'd put it down to cogging of the motor. But it's worth checking for any debris or damage to the spur or pinion - just to be sure. Make sure the motor feels to be turning by hand properly too.

[stampede vxlboy]

it runs like a dream but it did it when i got it off here off si coe
its had all new parts diff balls etc

[bigred5765]

if it only does that with the motor and pinion connected its most likely just the effect of the magnet inside your feeling and perfectly normal,as long as it run fine and sounds fine when you drive it then it is most likely,YES YOU GUESSED IT FINE,

[stampede vxlboy]

thanks mate i have been trying to tell people what it does should it be loud when you lift it off the floor
