WEll, the BB/speed 300's shafts are the same diameter as stock, so it must have a different diameter, get some calipers or try to measure the diameter, and find the right pinion for it (they sell all sorts of pinions, ya just gotta look around) either that or call or email hobby people.

jkerr0043 · #77 12-06-2002, 01:58 AM

I checked them w/ a mic and they are both 2mm shafts, but the 370 is splined. I just hooked it up to a battery and held some sand paper up to it for a few seconds. Smoothed out the splines and it fits now. Thanks

Hey guys.

My LHS is opening up a micro rs4 track, it will be carpet. And I want to get a micro and race there. I only have $300 to spend and I had this as my setup:
Micro RS4 Kit ($99)
Big block motor ($40)
Novak Spy Speed Control ($55)
Trinity 6-cell NiMH Pack ($30)

And I was going to use a MX-3 later, but any old one I have around for now.

Then this guy says I need to get like $500 more stuff to get it to race good and if I have to get a lot of mods then I don't want to get one, I would rather get a hyper 7 then spend that much on a micro. He also said the spy is not good enough and that I need to get a quantium. So is the micro fine stock or do I really need all this other stuff(alum. parts, carbon fiber chassis, etc.)?

Crashmaxx--buy a BRP SC-18 for $100 + radio and ESC, you will have a rece ready car that will beat any Micro!!! If you need more speed you can get the Big Block motor and Pod.....

Scrad · #80 12-06-2002, 02:27 PM

Don't get the BRP car, that thing doesn't handle for crap and is not worth it in my opinion...

CrashMaxx, the stuff on your list if fine to race with. The SPY is great, you don't need to spend the extra money on a quantum. The only upgrades you may need is a rear ball diff, but not really needed unless you have a problem with the stock. I used the stock rear diff till it locked up on me. You may want to look into some steel front universals, since you plan to run the BB. And maybe a pan chassis.

I ran an Peak Turbo, SPY, Orion pack, with the stock rear diff and a Penguin chassis and I always finished 1st or 2nd. I ended up 2nd for our 1st micro season. I also did very well with the stock chassis too. But the Penguin did make it easier to drive. I probably only have 250 maybe 300 into my micro at the most...

Crashmaxx · #81 12-06-2002, 02:33 PM

I decieded to use the stock motor for now, we should have a stock class, and I will upgrade later as needed. Thanks.

SC-18_Racer · #82 12-06-2002, 02:35 PM

Scrad---- A SC-18 will out run, out perform a top of the line Hop-up Micro ANYDAY of the week. At my LHS track no Micro has beat a SC-18, the Micro is 3-6 laps down....

jkerr0043 · #83 12-06-2002, 03:23 PM

I've got a little tip for anyone running a GH rear ball diff. When I got mine, I could not get it tight enough to not slip without it locking up. I race with the guys from Team Epic and they showed me what they do. They take a Team Losi thrust assembly and install it on the rear diff. That tightens up the slip and you still get the super smooth diff action.

I'm sorry but I don't think that guy has any idea what he is talking about. Here is what I would get:

Micro RS4 $80 I can give you a link to the people that sell them for $80 if you want.

Speed 300 Motor $20 or Elite Mod $40

Decent speed control aprox. $50 ( spy, quantum, ect)

6 cell pack $25 ( I make my own because you ahve to for my chassis and it is slightly cheaper most of the time) The trinity packs are too expensive for nothing more than what you can get for half the price IMO)

Pan chassis $13-40 Not a must but makes a big difference. You can get the ARM chassis, Ratzas, Epic, or Penguin. I have the Epic myself. I got it for $40 and it comes with a battery hold down strap, two rear plates to adjust susp. stiffness. (You don't need a micro servo like it says but they are helpful)

Rear ball diff $20-25 ( not a must but makes it handle better)

Front one-way or ball diff $20-25( same as above)

Alum pinion $3

Foam tires $15

That all totals up to about $300 and that is everything you could need for racing them. You could do it with $200 too. It's all on how serious you are about it and how much money you have.
Ask your track they may have a stock class too.

Scrad · #85 12-06-2002, 04:17 PM

SC-18, you must have some crappy Micro drivers if they can't beat the donut BRP machine. We had one person try his and it did donuts every where and then he got pissed off and threw it at the wall. Every person I know around here that had a BRP said it sucked and they like the Micro much better. Plus why are you coming into our thread anways? You have your own opinion and thats ok I respect that. I just wish I could show you my micro and put some money down on a race...

That guy has absolutley no clue what He is talking about, get 6 cells, ball diffs and your fine

Crashmaxx · #87 12-06-2002, 07:55 PM

I think I know what I am getting. Thanks.

k_sw31 · #88 12-06-2002, 08:01 PM

No prob

Got Speed · #89 12-07-2002, 12:07 AM

Yea, he seriously dosn't have a clue. lol

If your running the same cells, motor, and tires as the other guy you have the same chance.

Got Speed · #90 12-07-2002, 12:10 AM

SC-18 Racer- Seriously now, why are you posting here. You arn't adding to the discussion about micro RS4s. You have your opinion I have mine. I respect yours I ask you to respect mine.

InspGadgt · #91 12-07-2002, 01:29 AM

No...actually he does have a clue...it's like pan cars VS touring cars. On a well prepped high bite surface a pan car will eat up a touring car because they are so much lighter and have a lot less drag in the drive train. But on a less then perfect track the 4wd of touring cars gives it a decisive advantage. The BRP/HPI comparison is exactly the same. The BRP car is essentially a 1/18th scale pan car. So give it a track with very good traction and it's performance will be awesome. However very few tracks are in that kind of condition anymore so the Micro will be faster as it's 4wd makes it more adaptive to less then optimum track conditions.

ugman · #92 12-07-2002, 07:15 AM

Well, I'm getting a MicroRS4 for christmas and I was wondering what hop-ups, if any, I should get first. I'm getting the RTR version so that I have an extra radio just incase something breaks on my new one. Lookin forward to posting in here often...

No I was talking about the guy who said you needed to get $500 of upgrades to make a micro raceable.

None are needed but the most popular and "best to buy first" upgrades are.

Elite Mod or Big Block(speed 300)

6 cell battery

Ball Diffs

Pan Chassis

k_sw31 · #95 12-07-2002, 02:56 PM

Well, the most needed thing for a micro (stock) would be these:

Aluminum pinion (definatly)
Servo mount (if you really hate servo tape

)
6 cell battery pack (for more speed, 4 cells is good for tooling around the house)
If you want extreme speed, get a speed 300 motor, but with this you need other hop ups to deal with the power (new tires more often, front and rear ball diffs, etc.)

Hope this helps

InspGadgt · #96 12-07-2002, 04:00 PM

oh my bad...I thought it was just another BRP vs HPI thing...this forum gets so many posts its hard to keep up with them all

Crashmaxx · #97 12-07-2002, 09:50 PM

I went to the track. It isn't real big and everyone was using a stock motor. You really need the softer tires to grip on the carpet. I got to drive a micro, but the AAs were almost dead, so it was boreing, but not to hard to drive. All I think I need is a good 6 cell pack and I should be having fun. Racing starts sometime next month, can't wait.

k_sw31 · #98 12-07-2002, 10:03 PM

Crashmaxx- Instead of picking up the trinity pack for 30$, I suggest you pick up the pro-match 6 cell pack here, I have heard very good things about pro-match batteries, and plus it is cheaper than the trinity packs, I hear pro match cells can last up to 3 years in top condition

PS, If am correct, i think foams are really good for carpet.

k_sw31 · #99 12-08-2002, 01:20 AM

Hey guys,

I was just browsing through ebay and i came up with some interesting micro rs4 chassis.

THey are the wide kind where you can mount lots of stuff down low

PLus they have different colors

THe Item # is 1924212705

jkerr0043 · #**100** 12-08-2002, 02:22 AM

I just bought an Epic chassis and rebuilt my micro for racing next season. New body too as well as a hobby people 370 motor and Pro-Match cells. This thing is a little rocket. I can't wait until race season starts again in January.
