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.
