Official Nylint modifying thread

Those pics don't show it in its best light, I must say.
From above, it looks prettty OK
Cheers,

Maybe someone who's had the gearbox open could help:
What's in the part on the inside of the gearbox (nearest the tub) in the little ridges along the moulding?
If it's nothing critical, I've got an idea coming on
P.S. Nearly got 90deg. articulation

its where the motor sits isnt it? but im not sure, i'l have to have a look tomorrow,

also, i have to admit your servo attachment seems very simple to the people among this communty who arnt to be trusted with a drill, sander and model car in the same room

[Laughing Potato]

I think you have come up with a pretty darn clever way of doing the steering there Sam

You just need to alter somehow get a bar that steps down rather than run at that angle. Could you invert the servo, so the bar runs lower? I guess the servo is fixed with double sided tape?


The gear box runs the full lenght of the axle, so there is not much more you can cut off

[jimbob]

just as a side note and any crawler will tell you 90* articulation is not neccessary and sometimes to much causing it to top of as it switches CoG

im sure hwat you have atm is fine  probably around 75* is perfect

and as for servo mount i will be mixing the two... using LP mount and sammy's linkage as i feel this one will give better equal steering, with LP's one wheel will steer more then other in each direction i believe?
sammy it looks good but it might get scratched up on the front like that

IT CRAWLS AGAIN!!

 

I didn't glue the selector on the axle to lock into low.... turned out that the end section of the gearbox/reduction unit (yellow) houses a metal piece with three prongs which is pushed against a plate with indents for the prongs to grab, when overloaded the metal piece slips out to save the motor. Well mine was pretty worn (my 4 year old Nephew tested my crawler first) so I ran to B&Q and grabbed some epoxy and voila! No more clicking, just crawling.... or speeding... the choice is mine 

Next up will be the steering... B&Q do mini tread plate-like metal sheeting, might be time to knock myself up a bracket

[Pug205]

nice work stu, 

so basicy glued  the gearbox in place to stop it moving?

[Ghost]

no theres a piece in the box that slips when it cant move the wheels, glueing it shut will mean there wont be any power lose

[Stumungous]

nice work stu,

No, just the locking plate and the part with the prongs inside the last stage of the actual gearbox casing, not the motor/axle casing, the actual coloured gearbox casing. That way the prongs can't slide loose and skip and limit my crawlers abilities...

By the way... (Pushing my luck) I've just run it and it's crawled up 2-3 inch vertical step (my cougar drill box/havoc starter box ) Trouble is I'm not running springs (shock bits only) so it got to a point then stopped... if I was running with the springs (at a guess) it could have made it on to it.

Might look into giving it a tummy tuck, just got a shot of one that has had it done, does look much better... maybe give it a nice lil' skid plate as well

Here, judge for yourselves

[josh_smaxx]

that looks ace stumungous!    wish i had the paience to make mine look that good but i think i will keep mine performance minded 

[Ghost]

ive taken my nylint apart and done the tummy tuck, the servo the ESC, cut the treads, cut the springs extended the chassis both ends, glued the slipper in place shaved the bottom of the axles and sprayed the shell and the rims

phewwww

[Sammy]

To all who commented on my steering: thanks

LP, Do you think that if the lugs were cut off the servo and it was 'slid' down a bit, it would be OK? The top bar is the stock one connecting both wheels; that's OK there at the moment but the bottom one could do with moving down, although it's on balls inside the ends so it might be OK.
Picking up a transmitter today so we'll hopefully have it running tonight 

Update later

Lets see it then

It could be a tad low if you did that. Try a metal coat hanger as they bend quite easy to gain a step shape I think it would look better. I'm sure what you have done will work very well, and I like your thinking a lot I wonder if a MG micro servo would be good enough? I have one on the garage aswell................................ I think I'll give that a go on my spare car.


I'm going to fit my Wild Dagger wheels next, maybe over the weekend if I get time. I'm working again now, so everything has to slow down. I'm spraying the shell at the moment between lesson when I have time. Its a grey primer, but looks good and I doubt I'll now add the blue I intended.

[Ghost]

when my f***** camera gets fixed by cannon i will, i got one of those dremmels from woolies and it did the tummy tuck, the chassis extention isnt that good ut it works, ive replced the blue bits with rods becasue they werent long enough :@

[jimbob]

got mine 2day 

currently making servo plate which looks goood atm, just gotta attach it  gotta open up the gear box nd i wil see what this coloured bit is 

ya blue bits limit travel so they will be extended or something i dunno i got some rod here will see what happens 

[Sammy]

Waheyyy
All fixed up and working, finally got my rear end down to the LHS and bought up the required bits.
My findings: As LP suggested, I have moved the servo down a little; not much but every little helps.
Fixed ESC to chassis rail (not planning on running a body on this one) and put the motor-ESC connection box on the other side (all servo taped)
Using a Jato turnbuckle as the steering rod if anyone wanted to replicate it.

So, the specs of mine so far is:

Basic Nylint Jeep
Servo Mod (See earlier for my version)
No Body
Futaba 3001 servo
MTroniks RV Max ESC
Hitec 27Mhz AM TX+RX
Receiver in old battery compartment
6 Cell SubC Pack
Shocks (all on in stock fashion at the moment...

Planned:

Extend chassis a bit using LP or Ghost's method
Possibly custom make a chassis tub as it really doesn't suit my needs As I was just saying to "Ghost" I've got some time tomorrow so will post a CAD of the layout of the new chassis design

Cheers, and will get pics up later.

[jimbob]

well spent ages today maybe 5 hours doing mine

then find out my receiver was dead  but found another so it was all good.
e4verything is mounted find but i would agree that i am not able to run body atm with hobby gear but we will see.
servo mod looks good  might make a new one when feel like sawwing metal again 

PROBLEMS (i know haven't had many yet )

for some reason think one motor is running faster or front one isn't running properly (probably because i had a look inside gear box)
need to bend rod for steering 

now here's the big question !!!!
How many of you found that it doesn't steer enough for the servo or the wheels turn more in one direction i had a look and it looks like the axle is blocking them and probably nothing you can do about it really  :-[

anyway when i have fixed steering and hopefully motors  i will get a vid..
only got 6cm of ARTIC atm

[Stumungous]

that looks ace stumungous!    wish i had the paience to make mine look that good but i think i will keep mine performance minded 

Does look god doesn't it............................................ shame it's not mine.

Mine's just stock at the minute, to be honest between getting over being ill and clearing out crap that I don't need any more I haven't had much time, no promises but this weekend is looking good... also got some mini-style tread plate to make a funky looking bracket for the servo...

BTW, the epoxy failed on the front diff, this I suspect is down to the little amount I used, I've covered it in epoxy now and will leave it to cure for 2 days to make sure it's as solid as it can be... failing that it'll be time to go and track down some JB Weld

Love the steering servo's guys, might take me a while to get everything up and running as I've got nothing to play with to see if it'll fit...

Get Twisted

I'd been thinking about getting maximum axle twist all week. I still wanted to make it easy and using parts that most have lying around in spares. I spent a long sime on this, and lots of failed ideas. I wanted to do something different but was slowly losing the will to continue. After 3 hours everything I'd tried had not work or I'd gained such little extra twist it han't been worth it. The shock always limited the amount of twist possible, no matter what i did

Then, I had a major brain fart

What if the shocks could move? I've never before seen what I've come up with, and I'm pretty darn pleased with the result I've done lots of research on these Nylints, and I can safely say this hasn't been don YET



The pictures say it all






There is still work to finish on it, but you can see how good it is. I need to limit the amount of twist, as it can roll rough over and get stuck. I'll mount the shell is a way that it stops the servo arm rotating fully

[Pug205]

whoa 

very good  lp    

hav'nt seen that done before 

[Stumungous]

Loving it LP that's articulation and a half!!

I'm just starting on the bracket for the steering... spent today dying the links and roll cage, I aimed for black and got dark purple doesn't look too bad but obviously it wasn't what I was aiming for...

Anyway; moving on: I need a cheap ESC to use on this beast... anyone got any recommendations? Cheaper the better as it is the season to be cash-less

Any ESC should cope with these 280 motors, really cannot see it struggling.

[Sammy]

LP,
Does this only work with the extended rods?
Sam

[Ghost]

u should copyright it

very very very nice, and its no simple

[Laughing Potato]

Sam

All you would need to do is extend the single pivoting rod. Extend it to the point where the axle clears the chassis when twisted.

Over rotation is the only problem with this design, but if I have time that will get sorted tomorrow
