Need help finding 17mm hexes to fit on crt.5!!! Integy (designed for traxxas)Dont fit
 

I got my brushless crt.5 chassis off ebay and it looks pretty sweet! It is the PERFECT size for me... I wanted as close to rustler size as possible, and this will do it (mikes extended chassis).

Anyway...my biggest concern was putting these adaptors on it:
http://www3.towerhobbies.com/cgi-bin...?&I=LXTBP2&P=7

They fit the rustler axles just fine, so I was hoping/assuming they would fit the crt.5

They slide over and bolt up just fine BUT there is play/slop in them. I figured out that the crt.5 axle diameter is just slightly smaller than the traxxas axles. I tried sliding the crt.5 hex over the rustler axle to confirm this and it sure does NOT fit!

So... the integy hubs have a little bit of play when fully tightened down. I was thinking I could solve some of the problem by putting axle washers on in between the hub and the adaptor. I have not found any in my parts box yet (limited time to work on this truck when im at home). Think this would help, as it will pull the adaptor in tighter against the hub?

I am really diasspointed as I have tons of 1/8 tires I run on the rustler and REALLY want to run them on the crt.5!

I only have a single set (of 4) adaptors in my possession, so I was going to buy an additional set to run all 4 of the smaller offset (3/4 inch) adaptors since the crt.5 has equal length a-arms. Cant bring myself to make my parts order (need to get a lot of stuff... including my mod 1 pinions/bore reducer so I can actually run this little beast).

If anyone knows if another truck (rs4 mt?) or other have a slightly smaller axle diameter than the traxxas trucks, those would probably work. I just want to make sure before dropping another 25-35 bucks on some adapters (like new eras).


Any help is greatly appreciated!!!!!!

Dang! I was going with this idea also! CRAP!

I was going to use the New Era ones

http://www.neweramodels.com/item.cgi...=&part_id=8538

But I won now because im sure the problem will be the same as yours. Guess I have to go back to 30's series rims/tires now. Sigh...

I wonder if I can just use the 8mm axle hubs a truggy uses. And then have Mike, or someone make me something like his bore reducer to fit in there. I cant see any problems with that, other then getting them made. And then use something like the RC8T hubs for the offset, then we can run 0 offset, and have perfect width. Maybe Mugen, since I know my buddy has some I could have, and get this figured out

Time to get the ideas flowing!

You be the leader, I will follow...lol.
Proline 30 series are just too damn expensive! A full set is like 60 bucks..and I wanted to have at least one full set of dedicated streets and offroad (was thinking badlands and road rage) but im not about to spend 120 on two sets of damn rc tires/wheels!

I can get brand new 1/8 tires mounted on wheels off ebay for like 15 bucks a full set (was watching some badlands copy's and some slicks which would work perfect).

If we can make something happen, lets do it!

Alright, lets figure it out!

What kind of offset are you wanting to run on the rims? Zero right?

I can order some hubs (You want some also? I can get them alot cheaper then you can anywhere. PM Me if so)

And then we just need something to make up the dia difference. Im pretty sure the stock out put is 5mm (can you confirm this? I dont have calipers on hand) to 8mm. Would be cheap and simple enough to have Mike make us. And then bolt them up and go

I can get some Kyosho hubs, which are 12mm offset (or 1/2 in) So that would be plenty wide IMO, or we can do something like the RC8T ones, or some other brand, that has 3/4in off set, So we can have the car overall 1 in wider, or 1 1/2 wider. Either way works for me, Id probably pick the 3/4in ones my self, but what do you want?

We can do this for sure. Then once its all done, RCM Mike can sell them in his store, im sure were not the only ones that want this set up

This would be the equivalent to LPR's on the full size truggy, but here we use normal size truggy rims, with 2.2 truck tire stretched over them (and yes it looks, and works AWESOME! )

Ya all of my 1/8 rims are zero offset (the hubs connect to the furthest outside part of the wheel face).

I would be up for either the 3/4 or the 1/2... maybe 3/4, just for the extra width?

If you could shoot me a pm on the price of the hubs that would be cool. I am down at school (no access to rc stuff.. unfortunately its 150 miles away at home which sucks). So your saying stock stub axles are 5mm? Im not too sure...I was thinking thats rustler size? Maybe someone with a caliper and a crt.5 can help us out (maybe even mike?).

I am dying to bolt up my 1/8 tires onto this thing! I dont even have a desire to run it without them lol.

And I think doing it this way will be the cheapest too... cuz hubs are pretty cheap, and im sure mike can make some bore reducers relatively cheaply!

well I just found this searching for 30 series tires for crt .5...but this looks more interesting did you ever find the adaptors to do this?

I will shoot him a PM and see what the status is. A couple weeks back he had some of the parts and it was looking good.

Hopefully it works out! I am holding off on ordering my needed parts so I can hopefully order the extra widening parts and do the conversion.

bumpity bump

If Mike doesn't make then I did find someone interested in it - They just needed the measurements...

ok who's got the measurements?....common yappa jump in here with some help

I believe a few of you guys have seen my truck. Its not done, but closer..

Basically the widening mod, is using LS10 parts, they all fit no problems right into the normal stuff, but are probably .3 in at least wider per side (dont have the truck in front of me now...) And are ALOT stronger

You can run the upper arms if you wish, just need some lunsford or something turnbuckles that are longer, I just went away with them (no pics of that yet)

http://i377.photobucket.com/albums/o...Picture004.jpg

Still need my turnbuckles, drive shafts, bearings, and all that stuff. But once I figure that out, I know I think it was hpi nitro mt2 17mm adaptor hubs made by new era fit. So bam, and done!

Any questions, just ask

Great idea BOR! In the past I bought the LS10 steering knuckles to try on the crt.5. They are a lot stronger looking, but the bearings were smaller than the crt.5 so I didn't get around to actually trying them. That's awesome that the LS10 arms fit straight on to the crt.5 hinge pins. They do look quite a bit stronger than the stock arms.

I just added a bunch of power to my RCM chassis crt.5 (MM, Medusa 3300, 3S) so I'd like to beef up the truck even more. Over the winter I'll have to keep my eye out for a used LS10.

Keep us up to date on how the truck comes along.

Ya keep us updated :) I am anxious to see the parts list to see what it will cost to do the whole conversion.

This truck should be very beefy and bulletproof after all is said and done!

Thanks for doing the leg-work for us :)

Yea, the bearings are 5X10, not 5X11, duno why they did that

I had to dremel the front diff case a little bit because the arms have more material around the pin hole, But the rears fit absolutely no mods, and there is a good amount of play with the arms sliding, (not in a bad way) So you can mess with wheel base with shims, currently its shimmed so I have the most wheel base, but its something more to tune =)

For the conversion, maybe a 3rd of Mikes arms, But you cant beat machined alu arms, and hardened CVD's, but I dont have 200 or whatever they cost to blow on a set of arms... I wish I did, but I dont lol

The plastic parts, steering nuts and bearings should be about $30. Turnbuckles should be easy and cheap, $20 for steel. However the (4) CVDs are $60 forseeing the LS10 CVDs will work with the conversion. Have you found CVDs yet?

how did this turn into a widening thread from a 17mm fix thread?

i think it was kinda a two in one....

quote from post #11 "I think it was hpi nitro mt2 17mm adaptor hubs made by new era fit."

i think the idea is that with doing the widening mod, you can use the 17mm adapters from new era. and have stronger arms in the process. :neutral:

why cant neil explain things as nice as you.....:intello:

it does seem thought that this mod could cost as much as mikes extentions kit

I have not added it all up....I stopped when I hit $84 an decided the stock wheels are fine for now...lol

So the 17mm hubs dont need crazy off set, which jacks up bearings

:mdr:


Not nearly as much. And the arms are plastic, IMO I want my truggy to have plastic arms. The mod will cost alot more upfront to do, but once its done, its done, and arms are like 7 bucks for a 4 pack, c hubs are a few bucks ETC... Parts are alot stronger where Mikes arms still use the stock hubs and knuckles which would be a major week spot from what I found on my old .5

I will post a list of the needed parts when im done, but it will be fairly cheap, im not trying to make it insanely cheap, if thats wanted then use the stock set up, im just doing something for me being cheaper. If you like it, sweet, if not, then thats cool, just putting something else out there for people to try. Trying to give my part of time and money to do something cool like everyone else does testing parts, I just dont have any cash:lol:

dont get me wrong! :lol: I think its cool as hell. :intello:

i have just spent too much $$ recently to keep up, but trust me I will be watching your progress and looking forward to updates.

sorry if I came off negative, not my intension. I think the work you have done so far is awesome.:yipi:

Only as mike doesn't sell these....

PM me for the rest of the number

Hi, Thanks for your inquiry. The first thing I need to know about your CRT is does is use axle pins in all four axles? If so, what is the diameter of the pins and the axles? You'll have to give me a call about the Slash. 308-730-XXXX Thanks -Rob

Hi - Just wondering if you could make 17mm adapters for a CRT .5 - There is a lot of interest at RC-Monster.com/forum for these.

Also 17mm adapters for slash.

Rgds

No no, I didnt take it that way, Just trying to explain my reason behind the mod. I know most people would rather buy a kit, and bolt it on.

I think half the fun is messing with my car, if it turns out to be more money then I expected, at least its done, and other people can do the mod if the feel like it:mdr:

Sweet. Id buy a set of those too.

It is always nice to have options!

The adaptors can be used for people who just want to run the 17mm occasionally, and the new arms can be run for those who want to run 17mm full time.


Maybe I will see if he just wants to borrow an axle/pin to get the measurements dead on.

I will post here when he replies.

Anyone ever find a solution for running 17mm hex wheels on the CRT.5?

Id like to be able to do this, but it doesnt seem that there is an adapter to work. If there is anything out there Id love any info anyone has.

Maybe Mike could make a set of arms and adapters that would take the 17mm rims and not put any strain on the rest of the drive line

Do my LS10 mod, and u can use the 17mm adaptors that anyone makes for the HPI mt2, I forget who has the LS10 with 17mm adaptors, I think its Rootar

I went back and forth for almost 6 months with Rob Forsberg from Wheel Extensions.

-----DO NOT DEAL WITH HIM! -----

I sent him my Hub/axle/carrier off my crt.5 (putting it out of commission obviously, for this whole time). He promised me he would take the measurements and test fit the parts and have MY parts AND the extensions/adaptors back to me within 2 weeks (perfectly ok with me!). So I sent him my stuff and I had to call him CONSTANTLY over the next 3 months. He kept saying he was busy and didn’t have time. I finally said forget it, send the parts and the extensions and I will make them work myself.

So I get a package in the mail with only 4 17mm adaptors (none of my parts). I contact him and he swears he sent the parts. Weeks later I get another package from him with SOMEONE ELSES PARTS! Looked like they were from some sort of buggy. I tell him he sent me the wrong parts and I need mine back. He states “O, those were just some random extra parts I had laying around on my workbench”. I said, why the hell would you send me some random parts knowing they are not mine?

So in the end the extensions would not work (the diameter of the extension is drilled too large and he does not have a functioning enough brain to realize all he would have to do is drill the holes a smidgen smaller in productions and they would be just fine. No matter how many times I told him this he couldn’t get it through his head. I even asked for some with a 1/8 inch pilot hole centered on the extension (meaning I would drill it out to the axle size). And he said “NO” lol!

In the beginning he promised me he would “send some profit my way” for all the help. Not only did he LOSE MY PARTS (never got them back) I also ended up with NO EXTENSIONS. My truck was out of commission for almost half a year and I was out 20 bucks. He finally refunded the money for the extensions I paid (20 bucks) and I was out the money for my parts (34 bucks).

Bottom line… go somewhere else for extensions/adaptors!!!

Lol so on that note….any ideas???

umm what a bummer, but these things happen and at least he made an attempt to get u the right stuff back to u, but definatly time wasted and time is Money in my mind. im sure something can be made to work even if u have to fit a sleeve between the slop to make a 17mm work,

LOL I wouldnt call not paying for my parts an attempt to make things right. I was out 6 months, close to 10 bucks in mailing plus all my phone calls to him. O well live and learn.

The problem is the crt axle is just a HAIR smaller than a rustler/stampede axle. This means that obviously any product intended for the rustler/pede will have slop on the CRT.5 axle.
