SC10 4x4 Thread
On an unrelated note, I got my fans today. The 30x30 Yeah Racing fan puts out slightly more air than the 40x40 Speed Passion fan (the one like Pudge is running here: )

The YR piece will bolt right in (I already have a hole that size for the Novak fan) but I'm concerned about the amp draw on the BEC. Guess I'll find out soon enough, but I now understand why Cameron is getting his 540 to live. With that monster cooling it, it should never heat!
You wrote something patently false, I called you on it, you defend it by stating "some guy" told you so, I told you you were lied to (but feel free to believe it if you like) and then you defended your comment by saying some factory guy told you it was true? What a gyp. Do what you want, I don't care.

My fan is hooked directly to the battery post on the speed control. If you think it blows good on 6v wait till you see 8.4v

With a glitch buster and transponder I ran out of plug spots on the reciever.

Looks like that is the new Reedy 550 motor. Mayfield runs for Reedy so...
I know that the team Orion guys got the new 550 motors just before the event. Cav was running a 5.5 540 motor up until that so the reason he has a fan mounted.

Please believe me it was not false or a lie as you claim I am doing .....
again
stop trying to get on my goat ...
n
10 years !!!!!!

I have a head start on all of these boys cus I got me Sc4x4 a week before any of them when it was first released . oYeah !

Dang, there are a lot of mis-understandings going on. I feel left out... lol
Not to dredge up previous posts, but the main reason for the feel difference between bladder shocks and emulsion shocks is that on bladder shocks you only have air above the piston while emulsion shocks have air both above and below. Think of it this way:
Put a piston in the shock with no holes and assume it has a perfect seal against the body of the shock. Shock oil isn't compressible (or expandable) at all, so even with air above the piston (in the bladder) that is compressible the oil below the piston won't expand. The shock shaft will not move as the oil will not give whatsoever.
Put same said piston in an emulsion shock (after its been emulsified, good luck with that in real life) so you have air above and below the piston. Now, even though there aren't any holes in the piston for oil/air to pass through, the fact that you have a compressible substance on both sides of the piston means you can at least move it up and down a little bit compressing and expanding the air on each side of the piston.
As a patent pending product based on this notion, I'd like to bring back the AE volume compensator foam blocks used on the original tc3 shocks. With that below the piston and a bladder above you get the consistency of a bladder shock and closer than ever handling characteristics of an emulsion shock. Again, if mantis makes this product I demand my cut.
Moving on to the "scale-ability" of shocks and fluids that WC and MBA were talking about, they are both right. MBA, fluid dynamics don't change, but you cannot scale shocks and expect them to behave the same. WC was correct to say that shocks don't scale, even if he didn't know why.
If I wanted to build a scale model of an airplane wing that would normally fly at 200 mph and do testing on it I can't just throw a 1/20th scale wing in a wind tunnel and set the speed to 200mph (or even 10mph for a scale speed). You must also scale the fluid that the wing is in. That being said, you use a Reynolds number to calculate the density of the fluid you need to push your model wing through.
In short, we can't just copy full scale shocks and expect them to work the same. However, we can use things learned ON full scale shocks and appropriately modify a smaller shock to behave like the full scale shock, but it will be nowhere near a true "scaled down" model.

Wild cherry, if you haven't noticed, this guy thinks he's "house" and thinks he knows everything and can fix anything. All he does is troll and bash people from what I can tell. He's probably gonna bash me for this post but I don't care. I just wish this thread could get back to what its supposed to be about... helping people with there sc10 4x4's
My flame suit is on craig, it's only a matter of time!

to much pissing and moaning in here...
as far as the goat...it's dead, your goat was slaughtered by some paki kid and eaten for lunch, end of story...
secondly, who cares about a "team driver," they aren't gods.
