Haastnooit's AXR10 2.2s NCD SuDu1 / SuDu1 FL
 

The AX10 Scorpion is the first crawler I ever had, I got it a few years ago … and it was stock for quite a while, then had a shorttime flirt with a Hotracing chassis … but luckily she ended up as nice UGC Fastback 2. Then a bad thing happened to my AX10 … I got myself a XR10 and went MOA MAD, totally forgot about shafty’s.

But now my attention is back on it since I stopped racing other types of RC cars. I don’t know yet which way this thread is going to go, it could be the build of a new rig or a rebuild thread/introduction of my Fastback 2. Either way I decided she was in need of some nice wide AXR10 axles front and rear. Sole objective as everybody knows, to improve the steering by a (roughly estimated) bazillion gazillion percent. I used the Creation fab premium tubes to make these axles happen, and took some pics during the proces of installing them.

Creationfab premium tubes installation

Step 1 – Shorten the axle housing, flush with the nub on the housing.

Step 2 – Remove the bearingstop on the inside of the axlehousing.

Step 3 – Grind down the nub and ribs on the side of the axlehousing a bit so the tubes can slide over. Make sure the fit is nice and tight so take it slow with the grinding.

Step 4 – Insert the tubes and line up the holes. Secure the tubes to the axlehousing with the suplied screws

Mods:
- Axlehousing mod (post 1)
- countersunk XR10 lockout screwholes
- shaved XR10 axle shafts

http://i1123.photobucket.com/albums/...ps87589f55.jpg

It is not totally nescesary to perform this mod to the XR10 lockouts, but when I did this on my XR10, I thought that it looks much nicer then with a buttonhead. It has some sort of “factorylook” to it, when the screws are installed. Perhaps the way it could have been stock … lol

http://i1123.photobucket.com/albums/...ps326d01fd.jpg

To get the XR10 axle shafts to pass through the tubes, you have to shave down the collars next to the tang. Below some pics with stock long XR10 shafts to compare.

I still have to drill the holes to fasten the lockouts, but here is a pic of my fully assembled AXR10 rear axle.

Nice pics...I'm sure this will help out some guys who are looking to do these mods and aren't sure what is involved...and really how simple it is "thumbsup"

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Your bazillion gazillion percent improvement, Is that an approximation, or just hard cold fact?

I am more than sure that it is the daggum truth!

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Thanks Itty "thumbsup" I hope this will help others. When I was reading about the XR10 mod, I found usefull information scattered around several threads. But not always illustrated with clear pics, so this is my contribution to taking care of that

It is the daggum truth .... I got a real nifty angle measurement device I use all the time. I don't know where I got it from ... but it says "manufactured in Dr.evil's secret lair" on the back though :shock:

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Well you have to have a front axle as well, so here is the laydown ...

AXR10 front axle

Axial AX10 axlehousing
Axial AX10 Diffcase
Axial AX10 Diffgasket
Axial AX10 HD locker
Axial AX10 OD gears
Axial XR10 C-hubs
Axial XR10 knuckles
Axial XR10 steeringplates (zero ackerman)
Axial XR10 universals
Chaotic Crawlers XR10 Ti bent tierod
Creationfab premium tubes

Mods:
- axlehousing mod (post 1)
- universal mod

http://i1123.photobucket.com/albums/...pscaccacf8.jpg

After carefully doing the mod to the universals on both my XR10’s, I really did these up good. Now they are the smoothest set of XR10 universals I have …

http://i1123.photobucket.com/albums/...psf810e1f5.jpg

The front axle is not completely done yet, I have to finalize my steering setup and still have to mod the knuckles, drill holes for the C-hubs and some other odds and ends. But here it is a pic of my fully assembled AXR10 front axle.

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Great write up an a hell of a ion explaining it..

It's amazing the diff in how smooth the stock uni's can be with a little work on them. I have done it to 3 maybe 4 sets of them now. It's a very crucial mod to do for any steering over 45* with these.. IMO

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Thanks but what do you mean with ... " a ion" :mrgreen:

I agree with the uni mod, afterwards they are very mucho smoother throughout the whole cycle and you are rewarded with more possible steering ... crucial indeed when you want to max out your ride :twisted:

I think he just mistyped "a job"..."thumbsup"

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Dang ... I think you are right Jeremy ... oops, why don't I see that :oops:

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Lol.. darn smart phone key boards!

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

:mrgreen:

I ordered a new AX10 transmission today, guess I made my mind up and am going to build a new rig 8). I am now officially on the lookout for a new chassis, and had a quick look around RCC and came up with these options, not sure which way to go yet:

- Kush 2.2s
- SuDu1
- DIY chassis

Any suggestions ? Also better 50-50 or 40-60 ?

I know both Y-town crawlers and Chaotic crawlers have chassis' coming out, but those will probably be more pricy then I am willing to spend. But you never know. While I wait for the tranny, I will try to find some 3.5" shocks and look in to chassis options ...

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Hey Ronald, you can talk to me about some things? SuDu would be cool. .

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

SuDu One "thumbsup" From what I've seen they are great performing chassis... The Kush would not be a bad decision though either...

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Yeah, the SuDu looks very capable and cool "thumbsup" You did very well designing this chassis. What do you have in mind ?

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

You are right about the SuDu1 .... and I like the Kush as well. I asked Chris if he could make a CF version like Rcbro's. But he was not eager to do so for a single chassis ...

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Shock choice

I went through all my spares and leftovers the past days and gathered up two possible options as for shocks.

Option 1 is a set of Traxxas 3.5” bigbores, running Losi mini-T front springs. On the pic below the front springs are flying the “missing man formation” as I got both sets of pinks on my BJ4 right now. Also have the Dlux standoffs for mounting on the chassis …

Option 2 is a set of Axial plastic SCX10 shocks, running Losi mini-T rear springs and MRC silver springs. At this time I only have one complete set of the rear springs, as silver is in use, leaving me only with blue and green to choose from. Therefore I ripped some springs off the MRC and added them to this option. I probably should better get an extra set rears though …

http://i1123.photobucket.com/albums/...ps90049012.jpg

I am thinking of going with the SCX10 shocks initially, because of the light weight and the possible preload adjustment. Regarding smooth working there is not much difference between the two imo. What do you guys think ?

Oh an does anyone have a spring rate chart of the mini-T and MRC springs ? I cannot seem to find one …

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Here are the Mini-T rates,

http://www.rccrawler.com/forum/attac...ring-rates.png

The only thing I have been able to find on the MRC Spring rates is Soft and Very Soft.:roll:

Thank you for your detailed write up on the XR mod. Couldn't of been a better time, I was about to tear in and do it. It really answered some questions I had. Keeping the subscription to this thread warmed up. Much appreciated.

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Youre welcome dentonmac "thumbsup" Always good to know I could help someone out ...

Your picture is not showing, but I copied the url and saw it ... thanks. I was looking for a official list by Losi, but apparently it doesn't exist. You know that is the one list I found also, those are testresults of a user on the Losi forum, found here and summary below.

mini-T front springs (LOSB1117)
pink (soft) - 0.86
red (medium) - 1.38
orange (firm) - 2.04

mini-T rear springs (LOSB1119)
silver (soft) - 0.83
green (medium) - 1.52
blue (firm) - 1.69

I was hoping to find out where the MRC springs would fit in ... guess I will have to keep on looking.

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

If you send me a pair I'll measure them on my scale with my spring compression jig! :)

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

I am in Europe so that is a costly adventure, but thanks for the offer "thumbsup"

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Well choice of chassis has been made in a way I did not expect (check sig) .... thank you Tomi and Douwe "thumbsup"

So this build is getting really serious now, I got an AX10 tranny+gears underway, my SuDuOne is cut next week or the week after. Giving me time to decide how to go about the servoplate and rear linkmount.
Also will be using the delrin lowerlinks that are optional when buying a SuDuOne chassis. For uppers I will try some CF tubes.

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Very nice... Congrats on making them team "thumbsup" I'm sure you will love working with Tomi and Douwe :)

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Congrats Ronald...
;)

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Thanks guys, I am really stoked to be onboard the NCD team "thumbsup" Can't wait to get the chassis and get on with it ....

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Well ... it has been a while, but things are slooooooooowly moving along. I got my AX10 tranny+gears and some extra mini-T rears in a week ago. I will post some pics up when my chassis gets here. It is in the mail right now and will hopefully be here this weekend or beginning of next week "thumbsup"

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

nice build Ronald, i see you soon at Purmerend

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

I have been receiving parts for the past few weeks "thumbsup" and finally got everything together to get along with this build ... still working on the body though ... Progress ...

Chassis & Transmission

Axial AX10 Locked transmissionset
Axial spurgear 87T
Axial steel pinion 14T
NCD SuDuOne chassis

Mods:
- brass inserts transmissioncase
- shaved motorplate
- de-anodized transmission parts

I was fortunate enough to hook up with Team NCD and build up my 2.2s rig based on the SuDuOne chassis. It’s design is made by a fellow Dutchman (Douwe) and is very straightforward and very effective ! Great chassis design combined with Tomy’s topnotch machine work will lead to this ….

http://i1123.photobucket.com/albums/...psaf66a012.jpg

http://i1123.photobucket.com/albums/...psa662135c.jpg

The SuDu1 chassis was one of the first chassis’ (perhaps the first) offered for sale by vendor with the milled out skidplate design ... extra care taken by Team NCD to save you as many grams as possible "thumbsup".

The skidplate also flares out below the CF sideplates to prevent damaging the sideplates when sliding on the skid.

http://i1123.photobucket.com/albums/...ps86dd1d2c.jpg

http://i1123.photobucket.com/albums/...ps61f0b2a1.jpg

The first pics above are with the OG chassis braces, below some pics with a alternate chassisbrace design. Doubling up the upperlinkmounts to stiffen up the chassis some more, also making the chassis symmetrical.

http://i1123.photobucket.com/albums/...ps68b86b4c.jpg

http://i1123.photobucket.com/albums/...pse4c98731.jpg

http://i1123.photobucket.com/albums/...ps622e77e7.jpg

I really like the look of the v2 sidebraces and am going to use these for this build. Future availability of the new chassisbrace design will be probably be anounced in the vendors thread of the SuDuOne chassis, when ready. Here is a link:

NCD SuDuOne 2.2s/sportsman chassis

When I started this build my goal was to make this as “cost effective” as I could, meaning to use as many stock Axial parts as possible and only upgrade if nescesary for strenght and/or durability. Therefore I will start out with a totally stock Axial AX10 locked transmission with plastic gears, Axial spurgear and steel pinion.

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

That looks great! I always love watching your bulids cause they are soo clean and the pictures are nice and sharp :) Douwe showed me those new side pieces and they look great! What is the weight difference between the 2 different ones?

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Thanks Everett, and yes they do look very good "thumbsup"

I didn't get any weights at all on the chassis/tranny parts ... :oops: I'll get those when I get the upperlinks done ...

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

I just finished up installing the tranny in the chassis, tolerance is extremely tight where the motor hangs over the chassis plate. There is only room for a hair …. a thin one !! :mrgreen:

Here are some pics of the tranny mounted in the chassis ….

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Man that looks great...cant wait to get my chassis. Considering that my shafty rtr weight
Is at 3.5 lbs with the old aluminum black widow chassis i should be under that with the Sudu one. And better performance as well"thumbsup"

Great pics. Like your detailed description. Are you going to run a body only or go bodiless?

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Man that is looking good, love the v2 chassis braces. Gonna have to get a pair"thumbsup". I did notice a little flex in the chassis by the lower link mounts on the upright, the v2 should help minimize the flex

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Great looking build Ronald! Nice work.
You only need to use a little extra spacer for the upper links. To bring it a bit more away from the chassis. Just for clearance in movement.
I hope to receive my v2 also next week. So I can prepare it for the supercrawl in Germany

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Nice pics Ronald,i love de sidebraces is that the only different beween the two verslons
I have the new skidplate and the links all
I have next week my new airbrushes body

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Thanks .... chassisweight is around 60 grams with steel hardware, so you probably will loose some weight when switchting over ... "thumbsup"

Thanks Oz "thumbsup" I will run a body at first, and maybe switch over to bodyless later ... You just can't ignore the amzing looks of Tomy's redhot bodyless sportsman rig ... It is just wicked looking :twisted:

The v2 braces does add strength in the upperlink mounting area's but not very much effect on torsional stiffness, it is about the same as with the OG braces. Perhaps a added chassis spacer or a CF plate between the chassisbraces will add more torsional stiffness ...

Thanks Douwe "thumbsup" I received some 10mm delrin spacers with the sideplates, now I know where those are intended to go .... lol. I will check the clearance when working on the links and adjust if necessary ... "thumbsup"

Thanks Jan, and yes only difference with your chassis is the sidebraces ... Cool, I am curious how your body is going to look, who is painting it up for you ?

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

The painter is a friend his name is Karel and the end of this week i post some pics of the body
this a Nordic Crawler Design this Orange with Silver with on the two sides the Dutch Flag with my name
and i send Tomi a mail to order the new sidebraces and i come soon to you

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Those are nice colors, be sure to post up them pics. Just let me know when you got all your parts together and want to go at it ... "thumbsup"

re: Haastnooit's AXR10 2.2s NCD SuDuOne
 

Nordic Crawler Design offers several option parts at additional cost that are designed to work with the SuDuOne chassis. One … or actually two are the 4-linkmounts Front & Rear, usely available in aluminium or CF. They probably will work with other chassis’ as well, depending on your link set-up. There is no separate vendor thread up for these, if you are interested shoot Tomy a PM about it.

I will be running CF 4-linkmounts Front & Rear, I mounted them to the axle’s tonight … check it out:

Linkmounts Front & Rear

NCD Front 4-linkmount+E-tray
NCD Rear 4-linkmount

The front plate has a nice E-tray attached to be able to mount all your electronics on the front axle. Due to the extra slots in the servoplate you can mount your servo on the left, center or right.

http://i1123.photobucket.com/albums/...ps5d18d080.jpg

The complet rear axle linkmount consists of 3 parts, a CF plate and 2 delrin risers to attach the links to. I spaced up the delrin pieces with revo balls for the moment, I will be getting some taller pieces with a row of holes added when Tomy has them finished …

Those linkmounts look oh so very sharp IMO ... really happy with them "thumbsup"

Untill now I did not get any weights of parts at all, because I am not shooting at a specific weight I sort of forgot about it … BUT … for those interested in weight … I got some pics showing the weight of the half-assembly’s I got so far … enjoy :mrgreen:
