I´m just back from the first race with my MSX. All I can say this thing is ballistic.
Last time I used my old 415 that was indoors in april. For outdoors I had an other car. Now with indoor racing just beginning again what is rubber tires on carpet I´m back to the 415 again. With the MSX conversion now.
As some parts didn´t arrived in time I was going to the race with a half built car. Finished the car there with just enough time for one practice run before the heats started. But after about 10 laps someone crashed so hard into my car so the endbell of the motor broke and my practice was finished. It was just good absolutely nothing broke on the 415 even no tweak. Maybe because I´m using the 3mm chassis and the old suspension. But right from the beginning the setup was nearly perfect and I just tried some things in the heats then. Finally missed TQ by just 0.3 seconds, that´s with the addition of 2 heats (6 minutes each) according to our rules. A-Mains went similar with winning the first one and 2nd place on each of the 2nd and 3rd leg then.
Tomorrow I will have picture of the car. Now I´m just to tired after the way back to home.

TB EVO 3 Delrin Diff Outdrives

I was going thru my box of various Tamiya spare & option parts that I have collected in the past years & found NIP set of delrin outdrives & diff plates for the TB EVO3 that my brother sent to me a year ago. I currently have the other parts needed to make a diff unit. Was wondering though if the outdrives will fit the 415 for the rear. I can't recall if someone has done this already in the past postings when the kit first came out.

Any replies will be appreciated before I start building the diff.

Thanks.

Ran the MSX for the second time on the weekend, all i can say is i love this car, seems to carry a ton of corner speed and still has lots of steering. On a slow track i did a PB and was only 1 second off track record. Looking forward to our National titles coming up soon.

Hey JoeyE,

Which front diff did you use?

Thanks

You are better off sticking with the stock arms for carpet. You may have a hard time finding a good carpet setup with the LWT Arms.
The standard 415 with standard arms geometry was designed for tight, high traction tracks (typical carept tracks) where the LWT Arms were desinged for long, flowing tracks (typical asphalt).

If you switch to the standard arms, I have a killer carpet setup for foams if you want it.

Hi......I used the 415 rear diff joints. I put the joints on a lathe and filed them to where it fits the front. Just turn it on a lathe to the size you need and everything fits perfect! Make sure that you do both sides and not only one side.

I'll have to post all the pictures later of the coversion when I am done.

DESIGNED FOR ? I don't know where you have seen that really. It was designed for the TRF 404X, which later became the TRF 414 and from what i know, it hasn't been designed for FOAM. As far as I know, it's just a coincidence that it works well on high grip with foam. You can read that article about the development of the TRF 414 series.

Having said that, I can recall of Charlie Suangka saying he used the LW suspension indoors with foam, so I don't see it being a big problem. I myself use it on carpet with rubber.

Parx, good photos I've been unable to upload the photos of my modifications. I'l going to double check the shims I used under the posts. IN the front I used 0.3mm and rear I used 2x 0.7mm and 1x 1.0mm shim in order to get the plates to rest flat on the bulkheads.

When I used the 3mm shim in the rear, I felt it was too tall.

From my testing both sets of arms work well. The nice thing about the old arms is that they accomodate the front foam tires without any modifications. However the lw require you to run a very narrow front foam (like 25-26mm) or you will need to use a different steering knuckle like the hpi knuckle. Marc Rheinhard used the lw arms with the hpi knuckle when he won the vegas foam mod class. If you want a 2 degree caster option then the lw is the way to go, but if you don't need that option then the old arms work well.

Question Martin, I've built my carpet chassis using the standard arms to start. I have all the pieces for the LWT. When you say 2 degree option I' confused...I have an option package for the LWT steering C-hubs which say 2 degree and 4 degree.

Are your saying the stock LWT C-hubs are 2 degree and the 4 degree option adds an additional 2 degrees for a total of 4 degrees.

What's the castor on the standard arms C-hubs?
Thanks

standard arms C-hubs are 4° and there is no other available from Tamyia. The LW suspension does have 2 different C-hubs with either 2° or 4°.
What Martin wants saying is, if you want to have a 2° C-hub then the LW suspension is the only way to go. But if 4° is working for you then you also can go with the standard suspension.
