JKerr, Check out www.teamepic.net they have a setup link there for their chassis. Personally I think it's the best one on the market. I believe it's stock front tires with soft rears.

My TC3 dosen't run quiet.....? The belt driven cars are so quiet & feel smooth. My TC3 dosent feel te same. Is that o.k for a shaft driven car...? Or maybe something is wrong.......?

Please Help.

You should probably be asking that in the TC3 forum, but since I drive a TC3, you may want to check your srup and pinion to make sure they're clean and the gear mesh is correct. Also, have you broken in your ring and pinion gears? What you want to do is when you put the gearboxes togethter, Mark a point where the ring gear and the beveled pinion meet. This way, when you remove them, you can put them back in the exact same place. These gears were into each other and form a patteren and you want that pattern to stay the same. With new gear it may be a little noisy at first but as the gears wear into each other they will quiet out. Also make sure you're putting a little diff lube on those gears. There are a lot of other things that can make the car noisy but it everything is built correctly and tuned right, it shouldn't be much worse than a belt drive car.

Has anyone had a problem with the hpi front one-way? The people that I work with have had the same issues I have had. The plastic tube for the front diff/one-way breaks after about 2 min of running. The dogbones fly onto the track and then I have to go searching for them. Can anybody think of anyways to fix this or is the one-way a completely useless part?

Scarab RC · #**155** 12-13-2002, 10:08 AM

I called and wrote HPI about the plastic tabs breaking on the diff housing where they spline into the front pulley when you run the front one-way. They're very poor answer is that it shouldn't happen if you run the stock motor. You can also break them if you smack the boards to hard. I think HPI should be supporting this problem a bit more. They aren't even working on a new diff case design or anything. Everyone having this problem should call HPI and complain like I did. It's the only way they might address the problem. The HPI Customer Service Phone number is (949) 753-1099. CALL!

What are you talking about?

HPI made a alloy front diff case already!!!

Scarab RC · #**157** 12-13-2002, 12:39 PM

WHAT THE HELLL!!!!! I didn't know that!!!! The HPI customer service morons didn't say anything about it (I even called twice and talked to two different people!)!!! What's the part number? Where can I buy one?

Scarab RC · #**158** 12-13-2002, 12:45 PM

It's brand new on the HPI website. Part #72378. $35.00. Aluminum Front Diff Frame. It's about damn time. Wonder why the morons in customer service didn't know about this?

I went searching a few hours earlier and found the aluminum case. HPI should include it with the one-way because their is no way around breaking the plastic. I work at a local hobbytown usa and I know we will have to sell them together to get the one-way's out the door.
thanks for the info.

I just got my micro rs4. Any tips on building it?
How do I make it go fast!

I got myself a 10 tooth steal and this thing flys now. I was running the 11 tooth plastic for starters but the LHS didn't have the 11 tooth in just the 10. I'm really enjoying this car, can whip it out just about anywhere and runs times are at least 30 mins or more with the AA's I got. Can't image what a modifed and 7.2 can do, hope to get it on the local oval tomarrow and really get her smokin, maybee even show off to the other "larger" scale on-roaders. hehe

Tstalion79 · #**163** 12-13-2002, 10:06 PM

Guys instead of spending the 35 on that case, just get the GH front ball diff or one way. Smoother and more durable than the HPI one anyway. The HPI one also doesnt hold a setting well AT ALL. THey constantly change their "stickiness".

K_sw31,

That's funny!

!

GH is known for somewhat shoddy parts. I'd buy HPI and pay a higher premium for a better part. In most cases you get what you pay for. The aluminum case is new. My LHS's distributor doesn't even list it yet.

Question:

(This may be a stupid one, but in the Immortal words of Mr. Garrison, "There are no stupid questions, just stupid people.")

Does Carbon Fiber or Graphite act as a conductor? I sandwiched a battery pack inbetween the lower and upper deck of my Ratzas chassis with no shrink wrap to cover the connections. I slapped some two-sided tape on the bottom over the exposed connections and went on my way. That pack was peaked the night before and when I wen to run it the next day the voltage was around 3.4v, which is wierd to begin with. I'm thinking somehow I shorted the pack. What do you guys think? (Don't scold me about the stupid-ness of no shrink wrap and the two-sided tape stuff. It was late)

I am not sure if carbon fiber is a conductor but I think two sided tape is.

Hey~
Way to go finding that aluminum front diff housing. I just bought my friend's Micro off of him a few weeks ago and it's already broken. I got it for 225 and it has all three of the titanium chassis' made by Hardcore, a front one way that either the splines that grap the pulley break, or the pulley strips (which is one of the things broken right now), the Big Block, 1100 mAh 7.2 volt battery, LRP esc, Futaba radio, and oh ya, the front steel universals. I think i'll be getting that aluminum diff housing soon, that should help a lot. If only they made an aluminum front pulley. Or do they? The other thing broken is of course the left front knuckle arm, but I ordered a Megatech replacement one, so it shouldn't break. Any suggestions by anyone on what or what not to get aluminum. I want to pimp the thing, but I don't want it to be so damn heavy that it's slow, or way expensive. Anyways, any suggestions for upgrades that I don't already have? One more thing? Any suggestions for a sweet 150 mm body? I know what ones are made, and I run a Skyline body right now, and it's way way sweet, but I want a new one, and I'm thinkin either 360 Modena, Skyline again, or M3. Yes, I know that's about half of the 150 mm bodies but does anyone have any suggestions? Thanx

jkerr0043 · #**169** 12-14-2002, 02:41 AM

I like the Modena. Check mine out a few pages ago. http://www.radiocontrolzone.com/foru...&pagenumber=46
GH makes an aluminum front pully. Here's the link for that. http://66.70.235.59/Merchant2/mercha...ory_Code=mp_gh
If you want a pimped out back end, check out the Ratzas pro rear deck with VCS shock. It looks awesome and I like the way the shock handles too.

metalry101 · #**170** 12-14-2002, 03:00 AM

Thanx jkerr0043. Ur Micro is off the hook. The paint job is way tight. Thanx for the link for the aluminum pulley too. 10 bux? Hell ya, I can afford that. I love the Micro, cheap hop up stuff. I have an E-Maxx too, and everything for that is way expensive. Anyways, I don't think my micro is going to look like yours because I don't really plan on racing it, but damn it's cool to tell kids at school that I have a car that's 8 inches long, 4WD, and pulls 30+ mph. Their jaws just drop, it's soo cool. Anyways, I gotta get some shut eye, but thanx for the info, and to everyone else in the forum, I could still use some suggestions on what bodies you like, and what hop-ups to get. Cya

Scarab RC · #**171** 12-14-2002, 09:30 PM

Anyone else have an answer to my question above?

metalry101 · #**172** 12-14-2002, 09:36 PM

Dude~
I have no idea if carbon fiber acts as a conductor or not, but I'm almost positive that graphite does. Hell, carbon fiber and graphite may be almost the same thing, I don't know. But I do know that you're not supposed to go fishing in a lightning storm w/ a graphite rod becuz you'll BBQ ur own ass (that would be kinda kewl). In other words, I think graphite conducts pretty damn well, but I have no idea about the carbon fiber. Hope that helps. Cya

jkerr0043 · #**173** 12-15-2002, 02:33 AM

Graphite, carbon fiber, all of those are conductors. That's why you alson dont want to mount your receiver directly on the chassis and you really don't want the antenna touching it if you can help it.

I tested my two-sided tape. There is alot of resistance but not infinite. So if your battery was left there long enoughit would short it out. You can use electrical tape in the future if you don't want use shrink wrap. Shrink wrap is the best though.

Scarab RC · #**175** 12-15-2002, 11:57 AM

I shrunk wrapped the battery and everything was peachy. Did we all like the little scientific experiment with conductivity?
