i have been into r/c for years. i just got back into the hobby last year, and fell in love with 1/8 buggies. i have made up my mind to get a revo as soon as i sell a couple of other buggies. i visited www.prolineracing.com and discovered that 40 series tires seem to be the rage. why? what do you have to do to get rid of optidrive, reverse, and that electric start stuff? if i get one, i will immediately replace the body, wheels/tires (with 23mm hex adapters/40 series wabash wheels/40series bowtie tires), install the forward only conversion, and would prefer to use a shaft-start system, unless the electric start is pretty good. is the electric start pretty good?. i know these questions have probably been answered in numerous other threads, and could probably stand to be in another thread all together. my search didn't really turn up too much. thanks

The electric start works fine for me, reverse is easy to get rid of with the FOC, and the optidrive is as easy as taking it out and hookin the servos directly to the receiver.

The electric start is heavy. A shaft start is the best way to go. You get the convenience of electric start with less weight than a pull start. The traxxas easy starters are nice and convenient, but if you race, the weight is just too much.

does anybody offer an extended chassis for the revo? or does anyone know some links to sites that carry revo aftermarket stuff?

what size clutch bell does the revo use? 1/8 scale i am thinking?

RenegadeRevo

My Feedback: (1)

it's a 1/10th truck... *shrug* not sure... didn't really think about it.

jetphyxr

ballistic batteries offers a extended chassis.

http://www.ballisticbatteries.com/St...ShowLarge=True

it has a 1/10th scale clutch.

people running tz's are using 1/8th scale clutches, but it requires that the tranny be moved .250" forward.

i run a tm and have had no issues with a mip clutch.

you will benefit from the 1/8th scale clutch if you run a tz, or a .23 motor.

the rd racing bumpstart is THE only way to go.

thanks jetphyxr, looks like this project is going to be much more expensive than i anticipated.

jetphyxr

no problem,

let me know, i built mine to race, and i do every weekend. i will help any way i can.

just go by the path of removing weight, and improving durability.

i am currently not running a ext. chassis, but am looking.

lots of parts out there are just flash, and have no race value.

a stock truck is about 13 pounds, mine is currently at 9 lb, 5 oz with 23mm velos and pythons,
it is 8lb, 7 oz with monster clawz and bowties. (that is at race trim with fuel)

at those weights you dont need a big block, the tm is way fast, mine pulls the wheels shifting into second gear.

good luck, the revo is truly on top on the standard monster truck class.

what suspension setup do you have jet? body roll? rockers? shock oil? all that good stuff. I don't race but was seriously seriously thinking about it and I am curious how my setup compares to a non-newbie racers setup. I just took a stab at it and I think I'm pretty damn close to hittin the nail on the head.

Bruno

Hi, the stock truck is 9.4 lbs without fuel STOCK! I don't know where you got the 13 Lbs from?

Here, read this; (go to TECH DATA)
http://www.traxxas.com/REVO/revo.htm

I took mine at work, and it weighs 9.5 lbs on a digital scale. So that is pretty close to what Traxxas says, and it's stock (for now)

Cheers,
Bruno

bruno, my bad dude, a typo i guess, was suppose to be 10 pounds, my point is for a removal of almost 2 pounds. (unless of course you must run the heavy 23mm, and pythons)

afterburn,

this is my baseline set up for my home track. (the track is huge, and usually very loose.)

front suspension:

toe angle- 1 degree out
camber- 1 degree negative
p2 rockers
caster- 3 clips front, 1 clip rear
roll center- upper
pushrod- mid
bumpsteer- mid
shocks- orange springs, 5k oil, #1 piston

rear suspension:

toe angle- .5 degree out
camber- 1 degree negative
p2 rockers
roll center- upper
push rod- middle
reactive toe- mid
shocks- gold springs, 5k oil, piston #2

i run 50k oil in both diffs, it is advisable to run 30k.
i run 50k because of the rd racing quick turn. (it is basically a one way bearing on the front drive shaft. meaning that when the brakes are applied, it is only to the rear wheels.)

with that said, when my revo is in race trim, it has almost no brakes. (if i hit the brakes it will hardly slow the truck.) the only time that i brake is to correct in mid-air. this may sound odd, but with the quick turn you are using the engine as your brake. when you get off the throttle the compression of the engine naturally slows the truck, and with the quick turn, if you brake it will most likely spin the truck.

so back to the 50k diff oil, it impedes steering, and frees up the rear end, which allows me to drive deeper into a turn, and then throw the rear end out with out braking. make sense?

in high bite situations i run 30k up front, and 50k in the rear, unless i know that the track will go from high bite to loose during the course of the day, then i will run 4 rear caster, high bite, and switch to 3 rear, one front, as the track loosens up.

hope this helps, and doesnt confuse.

Cool! I figured it was a typo or something. I like yur racing set up. Steve Slayden has a very good set up here for racing as well;

what is quick turn? because otherwise, i am confused about usint engine braking with a centrifugal clutch to control the truck in the air.

jetphyxr

quick turn

http://www.rdracingproducts.com/stor...products_id=80

when the engine goes from wide open to idle with the truck at full speed, it will slow the truck.
the engine is resisting the drive train, as well as the natural tendency of the gearing to slow the truck.

with the quick turn, all that energy is going to the rear wheels. which in turn does not affect steering, and allows you to throw the rear end out.

as far as in the air, nose down give it gas to bring the nose up, if it is in the air nose up, using the brake will bring the nose down.

i don't want to use 40 size wheels, what is the alternative to the stock wheels and tires. i am not having much luck finding alternatives. or will the t-maxx wheels fit?

jetphyxr

traxxas hurricanes w/ traxxas responses!

Hey Zim, thanks for the CRX! It really turned my Revo on.

I'm considering several of the mods that you mentioned but for now I'm keeping the ezstart for convenience. I've got a set of responses/hurricanes and they are a ton better than the stocks. The Geminis are all cracked up after some fairly mild running. I have seen some 40s that fit the regular axles without the 23mm adapters. I may go this route and try to salvage the Talons if they will fit.

My next upgrade will likely be the quickturn. Maybe this will help my tendancy to over drive tight corners. The Revo really hooks up with the suspension set up in race stance.

glad you like it man, it served me well

It works the same way a one way front diff does in a sedan. It does take some getting used to when you fly, but those that can adapt really like it.

fhm101

The current hot all around wheel/tire setup for the revo is Panther pythons on either traxxas hurricane wheels or the same tire mounted in proline 40 series wheels. The pythons are a bit heavier than bowties or the new traxxas tires, but the extra weight does not seem to be a problem running an .18. The guy that won round 1 of the pro series west yeasterday runs pythons on 40 series wheels with an .18TM for power.
