I don't know yet...

My preference is to use either center diffs or trannies with a slipper. Mike's slipperential...when it is released...will do both!

To answer your question...you can simply install the collar that comes with that center solid shaft on the DM-1 stock 2-speed. It should work fine....when you get to that point there are plenty of members here that can help.

Ooooo thats pretty....

I think you need to strip that servo top plate to match and round the edges, add a couple of zip tires and you are all set...

PS you may want to look at a gyro... ;-) (real men cheat)

Thanks...I have a D-Box gyro that I am planning to take off of one of my trucks. I have my Spek transmitter torn apart now doing the Lipo mod and waiting for the battery to arrive...geesh! The suspense is killin me. I wanna drive this thing...or should I say pilot this thing.

Very Nice!!!!!!!!

I personally like the solid shaft. A center diff unloads too much and spins the front tires unnecessarily and you lose power. Unless you put really thick oil, and then where is the benefit? Maybe on a track where cornering is vital, but these have so much power that it's easy to drift around the corner if you want to turn tight.

I don't know what benefit a torsen diff (if that's what you mean by "spider") would offer. I can see using it in the front or rear to keep one side from unloading on corners. But the combination of stiff suspension and sway bars helps that a lot. Otherwise, it kinda acts like a solid shaft if used in the center...

That looks great . I almost got that car instead of my gtp . Does the battery hang of the chassis much ?.

It is a really nice kit car...I am continually impressed with the quality of the Ofna products that are available. I guess about 1/3 of the battery hangs off the chassis. The is probably too much for your comfort as I recall from your previous posts a long time ago...but the tray is delrin, and this is a street racer, and everything is bolted down nice and tight...

I used 90wt diff fluid (which was the thickest that I had on hand). I am going to try the diff and then try the center spool. I just wish somebody made a heavy duty center slipper to go with that solid shaft....

your probably right :lol:. Since it's a onroad car as long as your tray is securly mounted it should be all right .

Yeah, that would be nice. But believe me, the tires slip enough. :smile: Seriously, I don't think the lack of a slipper is a big deal. Other than controlling take-offs, the other use of a slipper I can think of is to absorb drivetrain shocks when landing from jumps. Do you plan to jump this? :wink:

I would love to see the video of this thing move! The snow is here to stay with us in CO for a while but hope to have mine built soon and wait for Spring or the parking lots to finally be cleared!

Those are good points...no jumps planned for this car. I am going to give it a few runs as is. If it diffs out too much and eats the front tires I will definitely swap for the solid center spool. I just did not want to keep the 2-speed because I NEED reverse and I used all of these parts (center diff) because I had them on-hand.

Are you sure you used the right oil??? That there is shock oil, no good for diffs!!

Hello, winter project. :smile: just wanted to know, can you list the price of all your parts you used, including price of the car....esc...motor....etc....


thank you.

hey,
that is a sick looking project! let us know when you run it and how it does. any chance of a vid? have you done the body yet? if its the same quality as the build it will be awesome i'm sure.

I could be wrong but silicone fluid is silicone fluid...the stuff I used was 9000cst viscosity not 90wt. Its pretty darn thick and seems to work fine in some of my other trucks.

I bought a lot of the parts over a long period of time when they were on sale or when I had some good coupon codes...but as an estimation:

$329 DM-1 Spec
$50 RC Monster motor mount
$75 RC Product Designs battery tray and diff top plate
$125 three Ofna Spider Diffs
$270 MMM and Neu Castle 2200kv combo
$100 JR Servo
$285 Flightpower 5S 5000mah battery
$85 Spektrum transceiver
$95 HPI D-Box gyro (not pictured)

YIKES it adds up quick.

I will definitely get a vid for you all...eventually.

As for a body...I am planning to contact Team3six to see what he can do for me. Any cool ideas on themes? I was thinking something associated with Tesla or maybe nuclear energy.

dude,
i love Tesla!! my wife and i actually had one of their songs played at our wedding. 5 man acoustical jam is a great album. i just love the acoustic stuff. hmm, how could you incorporate a Tesla theme? "Signs, signs, everywhere signs. blocking the scenery, breakin' my mind. do this, dont do that, cant you read the signs?"
i know they didnt originally write that one but sure made it sound good.

If you want to see the biggest variety of bodies for this car...........

I think he was refering to Nikola Tesla--the scientist!

http://en.wikipedia.org/wiki/Nikola_Tesla

lol, when I saw "Tesla", I immediately thought of a Tesla coil, not the band (especially with the reference to nuclear energy). But the band was good too. :smile:

I was referring to Nikola Tesla and his Tesla coil...but the band is awesome too:party:

Cool link....but whoa...those 50 Euro international shipping fees will kill ya!:surprised: I like that they sell bodies made of 1.5mm thick lexan.

1.5mm Lexan is about 0.060" - the same stuff Proline uses for their bodies.

Yeah I like that stuff...its practically indestructable. The body that came with the DM-1 Spec is sort of flimsy (probably 1mm thick lexan)...especially given the body's large dimensions L23.5 X W12.5 X H6.5. I guess I can see where each thickness of lexan has their distinct advantages and application...but I like the 1.5mm lexan.

Anybody know where I can find a mfg that makes bodies for the DM-1 Spec (with affordable shipping to USA:whistle:)?

All I know is the Kyosho Inferno GT (not GT2) bodies will fit. I am not sure if any others than the Ferrari F430 GT, Aston Martin and Subaru Impreza is produced. About $70 on eBay.

Cheap and in the USA. Pretty nice body. A freind of mine has one on his GTP.

Thanks all.

Are you sure the Infero GT bodies will fit? The Inferno chassis is an inch or so shorter than the DM-1 Spec. I lined up the stock Proto Form PF8 GT body on my DM-1 Spec and there just isn't an inch of excess room...so I am thinking that if I were to try and fit an Inferno GT body on the DM-1 Spec that it would be too small:neutral:

Did you actually see a DM-1 Spec with an Inferno body? Did the owner have to mod the bumbers/body mounts to make it fit?

No. I have not actually seen the Inferno GT bodies on a DM-1 Spec. I have yet to see the DM-1 Spec! Researching I have noticed people selling either the Protoform and/or Inferno GT bodies and mentioning they will fit either. My understanding that the Inferno GT has a 325mm (min.) wheelbase and knowing the DM-1 Spec has a 330mm wheelbase.

Sorry if I mislead anyone but was under the impression the bodies fit both based on the way sellers post their descriptions. Maybe the wheelbase is close but not fit due to suspension packaging. Anyway, I have purchased the Inferno GT Ferrari body and have every intent to fit it onto the DM-1 once that arrives. I can only speak from experience then . . .:mdr:

hello all,,,,, not to go off topic but, can the Inferno GT onRoad 1/8 Brushless go 90mph. someOne on youTube has several vids on it?

Thanks. Let us know when yours arrives. The only reason I asked if you had actually seen one mounted is because I intend to have Team3Six order and paint the body for me...and I want to be 100% sure that the Inferno bodies fit (without significant mod) before I drop that kind of loot.

I have attached a spreadsheet which you can use to calculate potential speed for your application. I am not sure if Kyosho uses the same diffs in the GT as they do in the buggy. I would say 90mph is pushing it but is possible nonetheless . . .

This is the latest on my build. I took it out for some speed runs and made some modifications. I put in some thicker center diff fluid and I still am not happy (frontend "diffs out" no matter what I do), so I am going to install the solid center shaft with a 51T spur. You were right Brian...I actually ordered the parts today. When I switch the diff out, I will also clean up the steering servo bracket as suggested!

I installed my HPI D-Box drift assist and it really seemed to help keep it steady on the high speed straight aways.


I also installed one of Mike's new battery trays...it just lined up better and provided more "opportunities" to bolt it down more securely--particularly towards the center of the chassis. Everything seems more solid now and there is less chassis flex.

Lastly...I put my amateur paint skills to work and painted the stock shell. Eventually, I'd still like to have a better/thicker shell painted by somebody who actually specializes in that sort of thing. After painting this monster, I have truly grown to appreciate the amount of work and effort that goes into the whole masking, painting, cutting, and sanding process.

Very Nice!!:yes:

Thanks. I can see myself building more of these types of cars...

The same build....
 

But with a Ofna GTP. Local nitro guys call electric's "flashlights." Well I plan on a lot of flash in lighting the gas boys up.

Truly sweet! I hope to get you feedback soon about the Kyosho bodies. When you say "diffs out" does that mean there is not adequate power transfer? I will look into the solid shafts as well. My plan was to go with the Kyosho 46T spur--I hope that will not be too small.
