Are you sure Grantothismo about those tires you have a link to, your tires look like:

[link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&W=000581428&I=LXDX80&P=K]http://www2.towerhobbies.com/cgi-bin/wti0001p?&W=000581428&I=LXDX80&P=K[/link]

Also, what is the difference on having those inserts.

Thanks a ton

It is a Ti chassis, and yes it is very light and like 46u said it is very pricey. Here is a link to the guys site that makes them. [link=http://f4iracing.extremevelocity.net/]http://f4iracing.extremevelocity.net/[/link]

I no this is a MT 2 thread but I have a question on my MT Racer. I finally got done breaking in my OS .15 CV-RX and got to run it hard today and I am having one problem or should I say my major’s problem. I read somewhere a long time ago about this but forget what the fix was. On one of my front left universal dog bones keep falling out of the cup on the differential. This is the only one and it is all most out just sitting. The other 3 are up in the cup much farther. All so I have the MT 2 shocks on the back. HPI says they are better then the MT because they thread at the bottom and do not come apart like the original. Bull my came apart all ready. Will check it out to night. PLEASE HELP.

What is the best pipe to run with the MT2 18SS? I was thinking of getting the THS Racing Pipe Set for Stadium 1/10 Stadium Trucks. Is that a good pipe for the price?

46U make sure you have 2 o-rings in the inner drive cup and 1 in the outer cup. Without all three there is too much play in the driveline. Also make sure your steering knuckles are tight and have no slop or this will also cause the bone to fall out. I got the aluminum knuckles and the CVDs and haven't had a problem since.

I have the CVD and aluminum knuckles. The CVD came in the MT Racer kit. The problem witch I fixed by shimming some what but I am still worried about is that the end of the CVD just on the front left is barely in the ball joint. The other 3 are fine. Like I said I shimmed it and it is better but still so close to the end. Here is a picture.

One thing is for sure the OS .15 CV-RX rocks!!!!!!!!!!!!!!! I all so like the 100cc tank I custom mounted. [X(]

Take a look at this and see the difference? The ones in the back are in a lot more then either of the front but he one on the right of the picture is the worse. Wish I could get it to look like the one on the left of the picture. I even took the differential apart and shim it where the ball end did not move in as much.

I purchased this chassis around Christmas, to start a project MT2. The project is going slow but I have made some head way on it, hopefully I will be able to post some better pics, and a progress report soon. I would like to take this time and thank everyone for the tremendous amount of information that they have shared on this thread and forum. I know that it has helped me out tremendously.

Thank you,

Bryan

P.S. Sorry about the fuzzy pic it is hard to get a good photo of the chassis because it is polished and the reflection from any light blurs the entire picture.

The only thing I do not like about the light chassis is with all the openings all the trash that gets in everything. I run on grass, leaves, pine straw and sticks it is bad enough with out all the openings. [8D]

You could try putting a small piece of fule line in the cups (I guess in the cup by the wheel) to push the dogbone in abit. Just like the rubber O rings but you can cut it to size. I have done this with mine. It may help, just dont make it to big or it constantly rubbs on the dogbone.

Also did you see they make a heavy duty titanium chassie, like the light weight one, but without the holes! hmmm i want it![sm=greedy.gif]

I have CVD so they all are one piece or should I say connected. I do have one small shim where the CVD goes into the bearing at the wheel and I cannot put in any more as if I do when you tight up the wheel nut it locks up the wheel. I all so took the ball cup out of the differential and put a shim on the ball cup before putting in the case just to make it where it did not fall out just by turning the wheels over by hand. I have not run it since I shimmed it and do not know when I will have a chance. I hate this as now that after all this time of building and buying parts I have it broke in.

Around 2 years and over $1,000! Like I said the OS .15 CV-RX really rips!!!!!!!!!!! It revs so fast at first I thought the slipper was slipping but it was OK. I have the stock flywheel and I am running on cut grass. I guess I am going to have to gear it up.

Yes I have known about these chassis for about 2 years. For what they cost I will stick with the 2.5mm heavy duty that came in my MT Racer kit.

Thanks all for your input!!!! Keep it coming.

My stock MT2 will be used for bashing around the yard, this truck I will be racing on a hard pack clay track, and also some on road racing. Trash and stuff should not be a problem (Hopefully).

46U:

When you got the CVD kit did it come with some plastic washers? If so they are used to space the CVD. Before you put the CVD into the rear bearing holder, place one or two of these spacers to space the CVD towards the diff. Should fix the problem. If you do not have the spacer you could try one of these and cut it down:

MT2 Beater:

I was using those tires, but have switched this last week. I'll post which I like best the Holeshots or the Bowties.

The CVD kits came with my HPI MT Racer kit. There is nothing about what you are talking about in the manual. The Racer kit is like what they call the SS kit now before they started making the SS kits. Came with a lot of up grades out of the box. I was looking at it tonight and notice on the front end the one wheel where the CVD is in the ball end farther it had more camber.

I have the titanium adjustable turn buckles and started to adjust them and if you put more camber they go in to the ball end farther. I now have where they are the same on each side. I have asked this question before and will ask again how much camber do most people run? Will some one send me a picture of their MT from the front with the wheels straight so I can see with the stock none adjustable turn buckles.

I have a camber gauge coming with a new set of wheels so I can set camber on all 4 wheels. Hard to do with wheels that have tires on them. I do not know if this makes a big difference on off road but has a lot to do with on road. Guess I will find out. I all so can set my toe in and toe out.
Thanks all for your input.

It always depends where you intend to run your truck... On a tight track you want more camber so that the truck slides in corners and not turtle. If there is lots of jumps, you want less camber, because you want the tires to have a little more surface to land, and it will make the truck less bouncy on landings. So trials and errors, to find out whats best for you

Running off road what camber front and rear seems to work best. For any one that might not know what I am talking about chamber is the wheels leaning in at the top, which is, plus camber and leaning out at the top minus camber. I wouldl think some plus camber would be best? What do others think? [8D]

As you all know I really like my HPI MT Racer and Nitro Rush. But I need something else to build besides my 1935 Harley VLD so I am going to get a Savage SS 4.6 kit in the next couple of weeks. Been spending a lot of time on the Savage thread lately. Every one keep this thread going.

This is just what I have heard and do not know this from experience. You will brake more parts and you better beef up the drive train as much as you can and it sill might not be enough. All so every thing fits real tight and you will have to make every thing work with the lack of room do to the big block engine. It will be harder to drive. Let us know if you try it and how it works.
