Why are you running that receiver pack as if you get a hump pack it will fix in the radio box with the receiver????? I hope to find a deal like I did on my Hyper 8 over a year ago shipped $374.

rEVOkING

its the 8.5 pro kit 6 spider diffs.. longer chassis,ect.. got it for $420.00 at a local shop. im new to buggys and all i can say is this buggy is so badass i want to buy another. it does everything perfect, jump, turn , stop.WOW. if i can keep up with a local pro with his mugen i cant wait until i get better im going to win a few

I know it is the 8.5 but why are you not running a hump pack and putting it in the radio box? It has the same radio box I am running on my Hyper 8 and I run a hump pack with it in the radio box. I know all about what has changed between the 8 and 8.5!

rEVOkING

lol i didnt even read who posted i just replied lol.. the buggy broke me $$ so im saving to buy some good parts. tires for the 8, and servos for revo..revo is sitting stripped right know.. iits only a few buck but when i go to the hobby shop i tend to buy alot. i want to get all my parts at once. and if i dont have cash..plastic suckers me in..hah

what is your setup. im running stock with the d30m 14Tbell/ stock spur?. need to count it..

i ballon in the front a bit but it jumps and turns great. braking is hard, i seem to float when braking,..i think its my tires mostly.

im curious what a good diff oil to use

i heard 4-4-4

7-2-4

i dunno yet..lol thanks bro.

Being mine has to be sanction legal most of this year I ran a STS D21B and next year will start with a STS D21T MKII. I run a 13 tooth CB and diff oil 7-7-3 but I do not have spider gear diffs. Does yours have spider gears all around or only in the center?

I know this is not great for some but for an old man of 53 half blind and only been racing for less then a year I am very content. I placed 10th over all in the Georgia Championship Sires, which consist of 8 rounds at 3 different tracks in Georgia. We had around 160 drivers participate in this event including pro divers like Ryan Lopez of coarse I was running sportsman class which was very competitive with drivers running pro lap times. Next year they will bump up! They awarded trophies and cash prices for the top 10 in each class. My Hyper 8 now has well over 8 gallons on it and has held up to my poor driving very well with very little breakage. Here are the winners.

rEVOkING

yes. i think so. well i think i might try your setup..

what tires do you run?

do you use wheel hub extenders ?

My Feedback: (3)

You have not checked to see about the diffs front and rear? According to everything I have read the US model is only suppose to have a center spider gear diff and standard front and rear. I have never run spider diffs not sure I would like them and they are heaver then the standard but from what I was told you normally run lighter oil in them.

For got to add I mostly run Bow Ties M3 as most the tracks I run on are hard packed Georgia Red clay.

nabanta

How long do the M3's last? I've been using the Bow-Ties M2's for a really long time. I probably have two or three gallons on my set and they still have a really good tread.

rEVOkING

it is real sandy and dusty where i race.. what would u suggest ?

46u

My Feedback: (3)

No the M3 do not last as long s the M2 but sure make a difference on hooking up on the tracks I run. I would say they last about 3 race days, which is around 1 gallon at the most. Now I normally will practice with M2 and race with M3.

Not sure what is best for sandy track but I would try Panther K2 medium if I had to make a guess.

FrankBlack

That must be a record, i find bowties are my favourtie tyre but the downside is they dont last long for me, 45min - 1 hr max and they are bald in the centre, the xtr's last a little longer but not much.

What is the surface like you run on?

FrankBlack

Hard packed clay, it blue grooves up nicely, traction roll city.





pics taken before anyone has run on it and after a heap of rain.

My Feedback: (3)

Strange as my Bow Ties hold up pretty good particularly the M2. Now I do not think I will get 3 gallons on them. Now this is what Georgia Red clay looks like and it is what they make bricks out of here!

rEVOkING

i bet it is awesome to race on.

ever try these tires..

http://www2.towerhobbies.com/cgi-bin...?&I=LXMXC5&P=0

how do the soft, medium, hard inserts foams work exactly ? what do they change ?

46u

My Feedback: (3)

Those look like they might work on the track you said was real sandy but if they have a hard compound that is what I recommend.

Hard, medium and soft inserts are like adding or taking out air in a 1 to 1 car.

Here is a cut and paste to help on deciding what tire to run.

1.2 Off-road tires
Off-road tires operate quite differently from on-road tires. They usually have some sort of tread pattern with pins that dig into the soil, or a series of small pins that scrape the top surface. This is entirely different from the friction model described above, where you had a smooth, hard surface and a uniform rubber contact patch.
Off-road traction is generally more complicated, the curves have more complex shapes, there are more types of soil, more transients, and there are more variables.
1.2.1 Tread Pattern
Size of the pins/blocks
There's a basic rule of thumb that says:"The softer the dirt, the bigger the pins need to be.". Long pins work by penetrating the (soft) soil, and short pins usually work by scraping off the upper layer of the soil.
Bear in mind that long pins and very soft compounds don't mix very well, then the spikes just bend over instead of penetrating the dirt.
Density of the pins/blocks
For a given tire width, the density of the pins is inversely proportional to the weight supported by each pin. There's usually an optimum, where the tire works best. For example: if a certain tire works very well when it's heavily loaded, but doesn't feel right when it isn't loaded, the tread pattern is probably too dense. This can happen in very dusty or soft conditions.
Tires for sticky mud usually have a very low spike density, because too much spikes cause too much stiction for the amount of traction they create, slowing the car down.
Pins or blocks
Round pins provide grip that feels the same in all directions, it feels consistent and it's somewhat easier to slide. Very useful on difficult, low-traction, bumpy tracks.
Square blocks feel more 'edgy', they can give the impression of generating slightly more grip, especially on smooth, hard surfaces. The forward traction they generate also feels nicer.
Center tread
Some tires have a larger tread pattern in the center, often shaped like an X, an I, or a T. In all cases, it increases forward traction dramatically.
Note that on 4WD cars, more forward traction from the front tires can also mean more steering.
1.2.2 Rubber compound
"The softer the surface, the harder the compound, and vice versa."
Some synthetic surfaces, like carpet or polished floors require specially formulated compounds, such as Schumacher's Yellow compound, and Medial Pro's Indoor compound.
Hard compounds
E.g. Losi Gold, ProLine XTR, Schumacher Blue & Green.
These work well on very soft surfaces, such as mud, damp, loose dirt and fresh grass. The idea is that the tire doesn't move, but the soil does.
Hard compound tires aren't sensitive to changes in foam insert.
Medium compounds
E.g. Losi Silver, ProLine M2, Schumacher Silver.
These compounds work well on most dirt surfaces. They're the best choice if the track is very dusty, or is starting to break up.
Soft compounds
E.g. Losi Red, ProLine M3, Schumacher Pink.
Soft compound tires work very well in blue-groove conditions, when there's enough rubber deposit on the track to make it darkish gray or black. They also work well on very hard surfaces, where the rubber compound is more important than the tread design.
1.2.3 Carcass shape
Round carcass
These tires have a rounded contact area, so they're not at all sensitive to camber changes. They're excellent for bumpy, rutted conditions; they'll provide consistent traction and won't hook into the ruts and make the car flip over. The downside is that they don't generate as much forward traction.
Flat carcass
These tires have a flat, or almost flat contact area. They provide excellent forward traction, and if camber is correct, also excellent cornering traction, but only on smooth surfaces. In bumpy sections, they feel inconsistent and can make the car flip over easily.

rEVOkING

thanks. i assumed that its the same as a 1:1 car but soft, and medium inserts dont serve much purpose of racing being that the tire ballons..right ? you would havd to have a really hard tire to make those compounds work i would think.

well i might just get some of those bull dog styles, but i have a set of oval spikes and they suckm. the bulldogs are simuliar to the ovals i wonder if i would have the same problem.

panther tires a expensive, and so soft.. what about ofna tires, anyone run'em?

nabanta

Thanks, I'll buy those for my next set.

scdrj

Agreed. You might even try Proline' Step up.

Jeff, congrats on the year's finish!

In my two 8.5s, the front and rear are just standard. I do not see why you would want one any other place than the center. The Spider diff is around 15g heavier. I sold my 8 for around a $50 loss, but since I had not bought any upgrades for it, I came out with the 8.5. My son's 8 has most of the upgrades already, so we will just buy the new radio box, shocks, and pin braces. I had already bought the motor mount, spider center diff, and chassis brace for his. You already have everything, so why change?

rabidsquirrel

Panther Komodo II's are probably the best all-around tire out there right now. Panther makes great tires!

OFNA Tires - Most of them suck. The ones that come with the new Hyper 8.5 seem pretty decent (A friend has been running them with success).

I'm sure that the GRP tires are good, but the one you linked to is probably better suited to grass or a muddy track... Euro tires tend to be designed for grass and other strange-to-american-racer surfaces. Not saying that this is 'wrong', just pointing out the differences...

rEVOkING

the stock tires that came with my 8.5 pro kit where ok but i foam is to soft, and i burned them up quick. the responded well, but suck when its time to break. has anypne use the badlands tire on a race buggy ?

My Feedback: (3)

I never use them, as I do not think they would work well on the hard packed Georgia Red clay tacks I run. Now on the sandy track you are talking about might. Now once again tires can me a personal preference type thing. You are just going to have to try and see.
