!!!TomErickson!!! if you run the Exotek Chassis i think you haft to run more weight to get it 50/50. also the lower you put your weight the less grip you will have but it make it more stable. if you make your chassis stiffer with carbon to take the flex out you will also have less grip but add steering(witch i dont think it needs). the Exotek Chassis put the weight low and make the chassis stiffer( it adds weight but you can do that your self and make it more balance). the only reason i would run it if i was traction rolling or getting on 2 wheels.
but if i where you i would try the locked front clutch Exotek has!!! it give you 100% power to the front wheel and you run the rear to the % you like with the slipper (kinda like a center diff)also it make the slipper work haft as hard so your pads last longer and motor run a cooler.

Thanks for your ideas on the Exotek parts. I need to decide were to invest my money for this car. I can see the benefits you mention.
So I really would like some input on the 2-stage pistons. Some swear by them but the pro's aren't using them. Should I get a set? MIP or RCShox?

Honestly, start with the stock pistons and see what you think. If you feel you need more rapid suspension action I would then give it a look.
Me personally the RC Shox pistons were quite beneficial for really rough sections. They also worked fine on indoors carpet. I didn't see the need to change them out, just use the appropriate shock oil.
As for which pro drivers use them, don't, etc. I think Mantisworx can comment on some names directly who does, don't, etc. for his product line.

There are many pro's that use them, but just like most upper level racers, they are not going to say that they do. My "black book" of pros gets longer by the week! Lutz won a major last year with them on his SC, and there are others.

They use them, just not at WC's track

For WC's conditions, I am assuming your UFOs would be kick butt there?
By the way, I don't recall but what all were the differences you had for it versus what you have in your truck on hand (diff versus vts, etc).

why don't u put sth. like a steel/aluminium plate under your chassis? It's cheaper, the cog lower, u can move the weight more forward and you could even mill some slots into the plate, like the dex410 has in the rear skidplate.

I do prefer the RCShox design over the MIP. They have a defined action were the MIP design, while providing more tunability, is a little more unproven to me.

I don't recall reading here much on the MIP pistons. I think someone was using them, but honestly just don't recall if they liked them or not.
When you order your Center Diff, go ahead and order some more pins. they are relatively cheap from what I recall, so might as well save on second shipping cost and have some spares on hand.

If you have ever been exposed to the Pinewood Derby you will know that the dads are really competitive and show their boys how to win! One very critical item for Pinewood Derby is weight. Getting the car to 5 oz. is maximizes the potential speed. So companies are out there that provide performance components for them. One key item is weights. Tungsten has a higher density than lead and many other alloys. So pin pointing the mass of these weights using Tungsten has become common. I plan to purchase some of the tungsten weights from this company to perfect the balance of my car. They are very small and very heavy and come in BBs, cylinders, and even putty. I am confident with these weights I can get a perfect balance without adding too much weight.

I just purchased the rc shox center diff v2 and used it at the track for the first time. What is the purpose of the pins inside the spur gear. It seems some people use all of them installed while others only use some. When driving the truck it still seems pretty swirly on the straights when i gun the throttle. Any help would be greatly appreciated.

No its not even close. when a slipper slips you are losing power and acceleration no matter how it is set, which is why some will tell you that it seems like they are losing acceleration when the slipper is set "proper". With any differential it does just that , differentiates between the front/rear and left/right. Since there is no slippage full power is either going to the front, rear or a combination of the two. Now with that said if your pins/fluid are too light (too little pins, added by Cain) by nature the diff will send power to where it can go to via the easiest path. So as the weight transfers to the rear and the front gets light power will go towards the front.
This is why the V1 dif was so badass on loose tracks because when grip is low so much power goes to the front that the rear will not spin barely if at all. when the V1 dif was tried on high grip tracks you would lose acceleration because the rear tires would immediately gain grip forcing all the power to go to the front and the front wheels would "dif out". So those of you that were on this thread remember when Cam and I were testing and testing and testing to find the right combination of balls and pin location to allow the dif to adjust to these situations. Some see the dif as just a spur gear with holes in it and balls but trust me there is more to it than that. I honestly believe that an RCShox center dif with all pins will outperform any slipper setup on any track and any grip levels. Here is something to think about, having to run 30k front dif fluid is not optimum. It works but it is just a bandaid because of the slipper. By definition what does thick front dif fluid do?
It has been proven that the slipper can obviously work but its a compromise. It has also been proven that a center dif can also work, in the end it just depends on preference. But a slipper will NEVER work good on loose conditions where as a center dif will work on both high bite and low grip conditions.

- push on entry

1) two stage pistons? I want to try these and see that MIP and RCShox both offer them. I had assumed that these get installed to allow for a firmer pack for the compression stroke for landings and softer extension for rough terrain. Is this correct? Which set of pistons would you recommend
I can say any the on rcshox pistons but I have two stage pistons that I made and mip piston the mip need a different setup but are consistency in a box lap times with two stage 30 31 29 31 and with mip 30 30 30 30
I run a rcshox v2 ball diff with a slite mod ss plates and no spring if you need a pro4 4600 I have one I need a buggy motor how do you like the rc8 e pm me off topic
Light weight is grate with mip

No prob. Feel free to make any changes you feel to it and please report back what you find. Getting more info on it from people using it can only make it better overall for everyone.

That's great to see what will be my home track soon. What is your set-up for Dirtburners? Slipper or ball diff? 8mm mod or not?
I would really like photo1151 to change his style and show the track videos from the driver's stand. It's really not easy to see the layout from his videos. I'm sure the driver's wouldn't mind.
