I was just wondering if anyone had used the new Protoform Stratus shell yet? Can anyone tell me the differences to the old Stratus?

Racer X- Great paint job on the car last night. Last night was pretty fun. It was also cool to see Jimmy running stock. I think that we should have all ran stock last night instead of running mod. Send me some pics of the second body once you're done with it. Also....stop trying to steal the guys I stole from AE (Tom)

Later

Pit-Racer: Most likely the reason you can't find the parts is because they are for the Fireblade (off road car). Either order them direct or have your shop order them for you (as suggested).

STL: I need Tom for motors, what do you need him for?

Wow...this car is so awesome, and we've got them so finely tuned, that we apparently dont have anything to talk about...

Well the main topic of interest is the rollcenter mod, so there doesn't seem to be anything else to talk about.

I finally got those stupid pulley guides to stop falling off, so there went all my problems!

I would like this car to have diffs as smooth as the TC3 or XXX-S, but I don't think thats going to happen!

Gotta love these grey belts though!

I'm with you on the diffs...not sure why they are so rough compared to the other cars out on the market??? Even after I clean and lube thoroughly in a rebuild, they are really grainy feeling after a few runs...Speaking of diffs, I've been having problems with the plastic outer shields on the rear diff coming off partially...I may just need to replace them, but they wont stay snapped on...

Other than that, once the parts get here later this week I'm going to do the roll center mod on my car, then reset it for asphalt parking lot racing again...we lost our indoor carpet track..

Default a non roll centre mod subject!

What are people doing to work with the natural tweek of their chassis apart from the Warpspeed replacement. I try to set up my car for equal cornerweights using a minimum of lead. So, with A hitec HS925MG serco, Novak TC2 and Sanwa Micro reciver, 10g of lead between the servo and ESC, Ultra Metal Hydride batteries and transponder behind the motor:
After setting for even ride hight I get

.../|\
RF| LF
--------
RR|LR

with the stock (27x1) motor and 30/86 gearing (rubber tyres)

...../|\
300|330
----------
325|375

Then by raising the LH ride hight 0.5 mm over the RHS I can get the distribution to:

....../|\
310 | 320
-------------
340 | 360


Now, with a mod motor, which is (well mine are) 20-30g heavier than a stock motor, and smaller gears to give correct rollout (also moving the motor rearwards) (btw, 22/86 currently w/ 60 dia foams)I can run:

....../|\
310 | 320
-------------
350 | 350

(no tranny) Which will come 320 each side front by running the tranny outside of servo TC3 style and 0.3mm higher ride hight LHS

So those numbers are good on paper, and the car really feels better to drive, but then, no one else is whinging loudly about this, and Schumacher were happy to release the car in this configuration. Great for clockwise tracks, but the only one is 3 hours drive from me! I've also heard that team drivers are using bigger spurs to move thier motor forwards, which sounds odd to me.

Who's got comments?

I got a few non-rollcenter questions too.

-Any of you guys ever run without the sway bars? I tried it without the rear one engaged once. What are your thoughts about what its like without them

-What about using the number 1 hole in the steering arm instead of the standard number 2 hole. I used the number 1 hole with my AxisPro and it turns on a dime while never losing the rear end.

-What about the number 2 hole in the suspension arm, anybody ever use it?

I'm asking about this stuff because I know most people don't mess with these particular adjustments. Just looking for some input.

Darkseid.....Glad to hear that you finally got he pulley fences to stay on....did you have to weld them on Anyway I have always run my car wth the sway bars so I cant help you there. I have been running the outside hole on the lower arm for a while now. I feel it lets you run a softer spring and still retain the responsiveness that the stiffer springs offer, but with the added ease of driving with softer springs. The #1 hole on the steering hub will make the car react faster off center but may reduce you over all amount of steering throw.

And for the Diffs I can get mine just as good as a TC3 or XXXS any time. I dont think I do anything special other then lightly sand and polish the rings with Mothers. I use Associated diff lubes, Black on the thrust assembly and Stealth lube on the balls and rings. Most times when the diff feels grainy its the thrust assembly that is the problem and it needs to be replaced. I never replace the diff balls as they are carbide and thats a lot harder then the crome steel they use to make the rings out of. I have had my car from last November and have yet to replace the diff balls. So I only replace my rings when they get too thin or too badly groved. Also I feel the diffs work better when they are a little grainy IMHO.

Darkseid: I run only the rear sway bar about 1/2 the time. Next week, I'm going to go back to an old setup from my A2 which uses no sway bars (just to try it out). That same setup uses the outter shock mount on the arms, which makes the spring feel 1/2 spring (or 2 1/2lbs) heavier (so a blue 15lb spring will 'feel' more like a 17.5lb spring). There's more to it than that since the shock is also being layed down more making it more proressive, but thats the quick and easy explaination). As for steering, I've run the 1 1/2 hole for almost three years. #1 hole gave the steering too much snap for me, #2 was too passive, so I drill a hole in between the two and it feels 'just right'...for my driving style. Hope that took care of all your points...

Kevin K: no, no welding needed! I actually accidentally broke the pulley fence for the 17 tooth pulley. It was an emergency, so I glued it back on anyway just so I could make my next race. As it happens, the thing never fell off again! So I left it that way.

I use the Associated lubes as well. Some how I got my front diff to be as smooth as the Losi and Assoc. diffs, but the rear one is usually toast a few races after a rebuild it. So, I figure its time to replace the rings. Since you mentioned it, I'll also take a closer look at the trust assembly.

Racer X: Yeah, the number one hole in the steering knuckle is pretty twitchy, but I might give it a try this weekend.

Thanks for the input guys. Sorry, I'm out of questions for now. So its back to the role center mod questions!

Ah, I forgot to ask a question... last weekend I spun my center pulley. The pin that goes through it literally made a circle inside the plastic. I know Pat and Dominic both have spun theirs too, so it's not a un-common problem. What is the deal with such a small pin going into the plastic? Seems to me if the pin was a bit larger it wouldn't put so much pressure on a small point. I guess I'll have to buy the alloy pulley and use my 20t until I get it.

A couple of questions put together a misssion first what is the easiest way to loosen the diffs?And the next one is there is something making a clicking sound in the rear end some where can't track it down any one have any suggestions?Also the drive train seems really tight any thing to remedy this besides breaking it in?And the car does not roll at all when no motor is in it by giving it a push?Any help would be great...
Thanks,
Craig
