X10 mods ?
 

Noticed on an X10 'for-sale' ad it mentioned a bearing mod and a prop shaft spring mod ?

What are these, do I need them, should I have them on my X10 ?
I remember hearing about a bearing mod somewhere near the spur gear on early cars to stop the spur from stripping, not sure how to do it, or if I need it.

Also I could do with some new Diff / Thrust balls, anyone know where to get some (and which ones) for sensible money, rather than getting the TTech ones ?

Northy ???

trust me the x10 needs no mods and doesnt strip spurs
do you know the x11s on its way?
the x10 is bomb proof for competant people.....like all the rest of rc/cars;)

scott are on something my mate the monk ate about 15 spurs last year:D

Ah that was me! I gave up my pred this winter indoors when it just looked at the gym mats and broke!

It's a marmite thing, eithere you love it or hate it, I was intrigued by it, tried it and now hate it!:p

the spring mod on the propshaft is a method af ensuring the propshaft is pushed all the way back into the rear pinion, as it was discovered that maybe the rear pinions were breaking because the propshaft was moving too far forwards into the front gearbox under certain conditions.

The spring allows the propshaft to move forwards and backwards as necessary when/if the chassis flexes without anything being damaged, and is probably more useful on a propshaft that has not been built precisely.

The question about needing one or not is entirely up to you.

The bearing mod probably related to the propshaft being supported by two bearings instead of one - again this is not a necessary modification. The X10 transmission, if built correctly, is bullet proof "out of the box" now.

As for diff/thrust balls, I have no idea - there is a thread on www.the-pred.co.uk that discusses the use of Tamiya thrustraces etc., but having never had an issue with the ceramic diffballs in the pred, i wouln't know which others fit the car.

Hope this helps.

Hey bert
your freinds x10 must have been built incorrectly (maybe to much end float in the prop,,or motormount not being sufficiently tight)
the x10 has been tried and definatly tested and dosent have any transmission issues as long as the pinion saver rings (supplied in kit) are fitted:rolleyes:
as you probably know my little Bro now owns ttech and if there was a real problem we would now be talking about it honestly and getting to bottom of it and putting it right
at my local club the pred outnumbers all other makes considerably and they all run fine
as burgie rightly said (if built correctly virtualy boombproof)

cheers

Bert, Please let me know your theary to why you done so many spurs:confused:

The spurs are hard. Much harder than that on something like a 501X / B4 / yoke etc, which you can actually bend. Since it's harder, its more brittle so landing a big jump (which is how I did my one) can potentially break it. If it was moulded like a b4 spur it wouldn't do the same thing I'm sure of it.

Thats how I see it anyway.

Jimmy isnt that what a slipper is for ?
the spur is made from delrin which is bearing material and is very flexible!
like i keep repeating there are no problems at all with the x10 reliability its a fantastic car with lots of inovative features some obvious some not so like king pin inclination....
the car needs no upgrades/mods of any kind:)
cheers

I have one here, and a b4 spur. The b4 spur is a bit thicker (about 1mm) but is a LOT more flexible. Not sure if the teeth can be made wider? clearance? but I still think if it was made like the b4 spur it would stand up better.
The gears are good - so if something is gonna slip or break (and the slipper is too tight) then the spur is the weakest point.

If you could make the slipper as easy and nice to adjust as the one on the 501X - then I think you'd never have a problem again. That car has several turns just to adjust to your preference.

Jimmy wait for the x11 ,,,not saying this will be a feature or not!
you will all have to wait and see:confused:

:) I have to agree with Scott on this one in the time my son & I have been running our XRS's we've only stripped one spur and that was caused by me not meshing the the gears properly in a hurried pinion swap. Drive trains been bullet proof otherwise.

I have NEVER stripped a spur in the X10.

G

Same here - i still have origional kit 73 tooth on my car.

I do however believe that the slipper is a weak point in the car. You have plates directly onto the gear. It does work to a point, but i firmly believe that it would improve the car if it had a proper PTFE (or similar) pad like every other slipper clutch that i have ever seen. I suspect this may help some of those that have had problems with spurs, and i think it would actually make the slipper a useful set up aid, which i don't think it is now.

Hello Matt w:)
the pred spur is made from delrin which is another type of bearing material such as ptfe...and also the nut tightens onto 3 coned washers which act as a spring(on other cars eg losi,asso) which is the same princible used in some losi diffs
maybe having the coned washers installed incorrectly is causing this weird spur problem:confused:

i think the correct orrientation is as below.....

SLIPPER NUT.....WASHER <......WASHER >........WASHER <......CLUTCH PLATE
hope this makes sense

scott ikonw u are an engineering genius so i will tell u a fact jimmy built the monks car so iwas assembled correctly check theck review he even modified thed the bearing assembly (ask jimmy) so there was no build error the car just ate spurs mate :D and where ur durango

I must say that i have seen alot of spurs go on the x10 ! reason y ?

Bert/Jimmy i am not happy at all with berts response:mad:
all i have done is offer advise or try to help with your problem bert.......
you know nothing about me bert and have just made this attack very personal :confused:
how old are you?
and my Durango is sitting next me in my work shop ,but not realy sure what thats got to do with the price of fish!:wtf:


modified the bearing assembly!!!!!!!! thats not a standard pred !!!!!so why not state that originaly......and i know you run this site jimmy but theres no need for this mod! its more than likely this causing the problem , but hey i dont care anymore:(
everything that comes out of you mouth/keyboard is negative

i think BERT you must lie awake thinking up weird ways to make up problems and derrogatory attacks
sincerly hope you get banned ( thought oople was better than this )

oh ...and Berty Baby.....learn to SPELL:D

Bert instead of trying to attack me :) why dont you engauge in helpfull posting to why this spur thing is happening.....as you are an engineer
isnt this what oople is for?
and you never answered the question to why your mates car chewed spurs
(trying to get back on track)
if you read my posts again you will see that none of the things i have said are...personal/attacking/or suggesting that i know better than anyone else
just trying to be helpfull and get to the bottom of this problem

i expect a response

cheers

lol

Bert was naughty with that message so I have deleted it - please PM me if there is a 'problem' since I don't always have time to read every post :) and that goes for everyone of course. If there is a problem, then let's be nice about it!

bearing mod - one of the team drivers invented it and never stripped a spur. The bearing mod was there to stop the spur moving so much when the chassis was twisted. (like when you land on one corner from a big jump.
I don't think we really need to get all silly about this - the design of the x10 spur was changed to make it stronger (one less tooth for the same diameter = stronger better profiled teeth).
If people are stripping the new spur, for whatever reason, it needs discussing as to why.

Scott,

It might be worth looking through the archives at the forum about the bearing mods that were carried out to the early x-10's and having a chat to the owners of these cars to find out why they did the modification in the first place.....they must have done this for a good reason.

It may or may not provide some of the answers to the "possible" spur problems and who knows...might provide some interesting ideas for the new x-11

I would definately like to see an easier to set slipper (maybe a coil spring? or...?) so you have a bigger (even slightly) range of adjustment.
Wider rear wheels also would be good.

:) Lets just first of all clear up one thing .....i am not anything at all to do with ttech ( so ideas thrown at me are a little wasted )
yes my brother Lewis owns ttech and hopefully (definately) will read this thread so maybe your inputs may sway certain decisions about the x11...maybe...:)
me comenting on this thread was purely to help people and sugest things that may have been over looked.
i myself/freinds have never had a spur problem you see.

just for Bert
here is a pic of ugly old me(unshaven,in need of hair cut,drinking beer) today the 9th of march holding my Durango 2005 in my kitchen....showing my todays local newspaper....and the latest edition of racer mag for proof that i still have the car!
www.rc10b4.com/gallery/showphoto.php/photo/3175/sort/1/cat/500/page/1
not realy sure why you asked but hopefully thats the end of that:wtf:
if Bert you would like to buy it, and that was why you were asking....you kinda went about it the wrong way
cheers

hope that cleared up a few things

Also Bert i see you have a pic of the stig as your avatar
do you know who he is?
i do.....pm me:)

Scott I know who/wher Bert is if you'd like to go round with the 'lads'

His name is Eric and he lives at 29 Acacia Road and when he eats a banana an amazing transformation occurs......lol.:D

Scott, yeah i understand what you're saying, and to a point agree - but i stand by my origional view that a duel pad slipper (with improved springing as Jimmy surgests) would be an improvement. That said, like i stated from the outset - i haven't ever stripped a spur. (que crunching sound next time i run car :rolleyes: )

The transmission is generally good - as is the car, if i didn't believe this i wouldn't still be running it. That said, i don't think it's perfect (perfect car doesn't exist - but i think the one you have in your hand probably comes closest!!) and believe there are a few things that could be improved. Slipper is one area for me, as is diff outdrives. I think the diffs would be better if they suppported the plates properly.

Best not Ernie might be there:)
and you dont want to mess with Ernie:(

probably not a good idea as my wife is a legal executive!

anyway you (the monk) cant blame me for having a little gripe with ernie or bert or what ever his name was:confused: forgotten!
he did call me a rather rude name for absolutely no reason (obviously off his head and needs putting down) on this public forum:o which can be read by women and little children+ inteligent people blush when they read stuff like that..and it puts them off:)
silly man but hey ho

could probably bash him a bit more but whats the point
its all fun and we are all freinds on here i would hope
anyway ive wasted enough time (i aint got) talking about rubbish now
and would very much like to get back on topic now
to sort out these pred mods....

cheers

Scott i also know who bert is ! This is pic of when he was young !!!
Hes the one in the yellow teeshirt !!! :D :D :D
http://www.dudleyradiocarclub.co.uk/...s/himley_3.jpg

Now hes a bit older now and hes also done some modelling !!!!!!:D :D :D

Just a bit of fun boyz :D

Scott I understand your gripe, i saw the post! Round here that's fighting talk, it's not right but its good fun and you can hug it out after!!:D

Back to the pred, I some how managed to get jimmy's review car (no28) and it had the bearing mod! I belive that on the early x10's the spur is set further forward, perhaps this could be causing stripping spurs.

Start new thred for x10
this is more fun, Scott i like it when u have a dig at bert :D :D :D

cheers pipe:D

time for a banana:D

erics back on the patch:mad:

its me thats my photo where else could it of come from:D

Hey Matt w
I take it by plates you meen diffrings?
and this is some thing again that i personaly havent had a problem with but i know some have snapped rings?
and yes they seem to sit a little odd on the outdrives but they seem to work.
one thing i personaly love about the predn X10 is its super free transmission!
have you ever known a car with no motor in to be so free?

All cars i believe have floors (dont even start asking us to name)
but thats the nature of the game (tech sport....i like to call it)

the pred is an xtremely advanced car......for instance....when i measure most cars geometry an odd pattern starts to occur
they are uncanily similar (lots)
you see most cars have say a 75mm long wishbone (for arguments sake)
with a slightly shorter top arm (camber) this gives camber change.....yes...with me so far..bear with me..
The good old pred has huge length wishbones (actualy longer than a LOSIxxxt/associated T4 trucks) with very short top arms (camber) but still has the same amount of camber change as the other cars....weird....

its the only car that i know that does this and geometricaly is a work of art....
and is the only buggy i know of that uses KPI (king pin inclination)
and i could keep banging on and on but i will spare you :)

and i have spoken to a few other manufacturers that agree that geometricaly the pred is awesome (probably the best) and they thought that richards ideas and understanding were phenomanol

thanks
that old durango,s quite good as well;) ;)

The HPI Pro4

Things I would see changed before I ever would part cash for an X10

Slipper plates with pads, the gear material should not be used as a stressed part of the drivetrain.
more resilient spurs
A propper stiff coiled spring (that don't got coil nound to get the slipper to stop slipping) as conical washers tend to be a more on/off affair.
Propshaft tied into the motor mount, to reduce and deflection (which is only minor)
Prop shaft to be assembled in the kit, not left to chance by the customer.

Scott, yeah plates/rings, same thing. Again, i haven't had a problem either, but i have seen some that have. I always believe that the carrier should be incontact with the ring on the same pcd as the balls - just for more support and hence more consistancy.

You're right that most cars now have similar geometry - some of them even use the same bits as we all know.
