1/4 Scale Grave Digger Part 16 with Conley V8

[45olives]

hi i love your build i am building a truck my self very soon also but i am wondering were you bought the new servo from and how much it was and how do you have it hooked up i appreciate greatly if you could tell me thankyou

[rcWizzard]

To - @45olives

Check out part 17 for the new servo, and part FAQ for info/spec's on the Servo.

Thanks.

[RChero1010]

@rcWizzard Personal opinion, but even with the new servo in p17, I think you need to try to run dual servos. You can try to borrow the design of the Traxxas E-Maxx, like from an exploded view in a manual.(which you can view online, just google emaxx manual)

[DaliriusD]

fantastic job on the steering!

[KingRcMitch]

word of advice i wouldnt be running such a small steering servo on those big wheels just gonna ruin them

[rcWizzard]

To - @KingRcMitch

I advise you to check out part 17 :-).

[BlackSGMan]

The air cleaner is so cute :D

[Leonek1321]

That's an epic bulid ! Big respect for patience and work put in it !!!

[experenceturbulance]

if there was a belt on this you could put a cute little rad on it but that would be tedious and the fins would be very delicate, also i dont see anything for rad hoses on the block do i? and making the ports would be hard, anything on that little engine would be hard thats why i wanna know if it truley is a 4 stroke, anyway this truck is very awesome to say the least, in my point of view its ' dope 'anyway goodbyeim going to pay more attention to your video then watch more. answer some q's eh?

[experenceturbulance]

anyway so down to my question, i see your fuel tank there and im just wondering, that little v8 is a 4 stroke correct? i dont think it will burn so much gas up so you dont need such a big tank, a side note i wonder what kind of oil you put in that? must be very thin if so, ok about that fuel tank. i have to ask what is the purpuse of the water tanks? im not sure but to me they look like good fuel tanks unless your going to be cooling it with that but that would be silly,theres no cams on this?

[rcWizzard]

To - @experenceturbulance

Yes, it's 4-stroke. Watch the level in the fuel tank in part 1. It will go thru some fuel. And this tank is fairly close to scale. No oil in the engine, the fuel does the lubrication. The water tanks are to hold water to cool the engine. The engine has a singe cam shaft.

[experenceturbulance]

i like your brakes, very simple drum brakes and the simplicity saves you time, also isint even noticable when the wheel is on, well except for that pivoting piece, you could have made something like on a old motorcycle but smaller and with a little pully, anyway sorry if im not making much sence im just trying to throw something out there, ive seen all these videos, well atleast the later ones of this taking form, none of the frame building ones (if there was) and ive seen nothing past this

[rcWizzard]

To - @experenceturbulance

Check out part 18 for better brakes.

[yoyo199]

Do you have the new sway bars that the trucks have now so when you get some air if you plan on jumping it the sway bars wont snap and swing out??

[rcWizzard]

To - @yoyo199

No, these are like Grave Digger #7.

[wildefifi111292]

RESPECT !!!, I wouldn't have the patience

[rcWizzard]

To - @wildefifi111292

Thanks man!

[DcrawFBM]

looks great i like the way you did the tires you can take pride in them

[rcWizzard]

To - @DcrawFBM

Thanks man!

[elpocho1999]

Im guessing its remote control

[rcWizzard]

To - @elpocho1999

Yes, it's RC.

[akura2]

YOu mentioned that you were having issues figuring out the brakes, but aren't the brakes on monster trucks at the pumpkin?... that might be a solutiion

[rcWizzard]

To - @akura2

Actually no. With a differential, when the break is on the drive shaft, if a tire loses traction it will spin in reverse and the other tire will free wheel, meaning no brakes at all. If the axle were 1 piece then a DS brake would work but half the braking power of this setup. Check out part 19.

[kmart1303]

This thing is sick! Great job man! I'm not trying to hate, but how is this 1/4 scale? Looks much smaller than 1/4 scale.

[rcWizzard]

To - @kmart1303

Grave Digger #20 is 16 feet long. This is 4 feet long. 1/4 Scale, Right!

Did you see part 11B?

[bassoundlikethunda]

what kind of transmission and stuff do you use? engine details?

[rcWizzard]

To - @bassoundlikethunda

The engine is a Conley V8. Trans is non-functional. It's there to look real and hold the out put shaft.

Want more engine details?? Go to ConleyPrecision. com

[foxrider89ify]

do u actually use it?

[rcWizzard]

To - @foxrider89ify

Use it?

I'm still building it.

[01161996bubba]

Will it be four wheel steer like the true gravedigger

[rcWizzard]

To - @01161996bubba

An axle with Drive and Steering would be difficult to make. So it will be 2WS for a while.

[local631]

have an idea for your braking system, why not take them out of the rims and put disc and caliber on shaft right where it meets the rearend you could mount the caliber onto the rearend and the disk could be drilled and mounted between the shaft and rearend yoke...thats how i did a race kart i built out of spare parts..

[rcWizzard]

To - @local631

Check out part 18.

[xXShadowRejectsXx]

good video! to be honest i think you apply for a guiness world record for like most scale grave digger or monster truck you may get a entry to a book! that would be cool!

[VanillaSwisher]

Will / Does it really run?

[rcWizzard]

To - @VanillaSwisher

Yes it will / check out part 1.

[24omw]

Wow you have the best rc monstertruck i ve ever seen .

[Infernostar18]

ok, you said your gonna have problems figuring out a steering system for a front end 4 wheel drive? its simple. i can help you out with a few drawings.

[rcWizzard]

@Infernostar18

Drawing it is the easy part, machining it is the hard part.

[Randomshit1353]

hey wizzard you need a stronger servo up front. that will not cut the mustard very good when you need to make a sharp turn instantaneously @ 30-50 mph.

[rcWizzard]

@Randomshit1353

Check out the new servo in part 17.

[Randomshit1353]

@rcWizzard i did looks good, maybe a TINY bit stronger, also put more articulation so it turns a tighter angle (36-45 degree angle)

[cwthemachinist]

As far as the brakes go, you've made all of these other cool custom parts, why don't you make a pinion brake set-up? Then you would have the advantage of torque multiplication with the gearing as well.

[rcWizzard]

@cwthemachinist

Check out part 19.

[onebadsavage26]

I've just started a 1/4 scale rock crawler and like your's it's all scratch built - not enough for a video yet, but I was wondering if you built the u-joints or bought them? If you built them do you have a cnc mill?

[rcWizzard]

@onebadsavage26

Are you referring to the drive shaft from the center Transfer Case to the rear Axle?

I do Not have a CNC Mill. :-( 

[onebadsavage26]

@rcWizzard... I saw in another video that you bought the rear driveshaft. I tried to buy some u-joints up here in Canada and they were like $160 each and I need 8 of them...4WD and 4 wheel steer...gonna try to machine them on my lathe/mill combo machine. You do some nice machining on that rear axle for no cnc. Awsome job.

[rcWizzard]

@onebadsavage26

Thanks man.

Yes, that drive shaft was expensive, made of Stainless Steel.

[MrBlaster24]

homemade. Thats how you spell R.C.

[Dejvd001]

this is home made ??? very nice car !!!!! 

[rcWizzard]

@Dejvd001

Yes, this Truck is all scratch built.

Thanks!!

[smallfish1960]

a single disc on the drive shaft diff side on the yolk ??? Just sayin IDK

[rcWizzard]

@smallfish1960

Watch video part "16 Again" skip to 4:30 mins.

[smallfish1960]

@rcWizzard LOL the video is 4:20 long,,,I see what you did,,,well done. Thanx for sharing!

[smallfish1960]

@rcWizzard yeah I saw it after I posted

[baptistedeschrevel]

how much does the tank hold?? a liter?? half???

[rcWizzard]

@baptistedeschrevel

16 oz or so.

[bckillick]

steering is ingenious, the homemade servo saver is great...whens the next video coming out?

[rjtdog]

man that would have be cool if someone could sit in it like a 6 year old and he could have the remote in his had and drive it around

[crabbywelder]

hey did you give up? when can i see the new video

[rcWizzard]

@crabbywelder

Did not give up. #19 will be a few weeks.

[crabbywelder]

@rcWizzard hows it goin? still waiting patiently !!!!

[rcWizzard]

@crabbywelder

Got the brake parts, need to make a few spacers before the next video. So next weekend if not this.

[rdnk72182]

the new front diff looks much MUCH better my friend

[focaatdisney]

Were you the kind of kid who saw something big like a big jet or like a monster truck and wished it can be an rc that would act like a the real thing

[rcWizzard]

@focaatdisney

I still am that kid.

[JonK660]

put brakes on the driveshft

[rcWizzard]

@JonK660

Watch part "16 Again" skip to 4:30.

[s10kid9]

if your going scale you should put the brakes on the drive shaft just like the real thing

[rcWizzard]

@s10kid9

Check out video part "16 Again" skip to 4:30.

[eclips1990]

maybe a trany break would work better then disk

[rccunha100]

you sould get the bisk brakes that they make for the baja 5t or 5b

[rcWizzard]

@rccunha100

Check out part 18.

[colchilibeck]

have you thought about doing a tranny brake instead of rear brakes at the wheels?

[rcWizzard]

@colchilibeck

Check out video part "16 Again" skip to 4:30.

[popomonstor]

Can you tell me when we are gonna get to see her fire upp?

[rcWizzard]

@popomonstor

Check out part 1.

[Uberrallyman]

that is sexy

[rcWizzard]

@02468bc

2 springs inside, with the piston between them, on a threaded shaft.

I made it.

[TheFishman77]

The new front axle is sooooooooo much nicer Wiz. great swap. I was giving you hell about the old one, and it not being 4wd; but wow. that front end 4wd or not makes the project immaculate. aren't you glad there are guys like me out there? I can't wait to see her run!!!!!!! please finish her!!!!! Take care Wiz.

[urgeone]

dude! thats so awesome dont know what to say..

[rcWizzard]

@dua0001

Check out part "16 Again", skip to 4:30 minutes.

Then part 18 for the new brakes.

[hotface28]

that think is sick

[meaghanbeast]

when will it be done

[rcWizzard]

@meaghanbeast

Many months.

[Johnnytotal]

once again, awesome work.

[scorphound]

mount a brake rotor in front of your axle like rock crawlers do then you only have to use one rotor and caliper

[rcWizzard]

@scorphound

Watch video part "16 Again", skip to 4:30.

[Sierrascoperida24]

what did you make ths chassis out of it looks soldered???

[rcWizzard]

@Sierrascoperida24

Mild Steel, MIG Welded.

[irule255]

WOW i have followed from video 1 to video 16.When you post a video i would love if you could pm me i would love to see that thing run.

[mlbdrums]

I had the same prob with the video. I found that I needed a bigger hard drive, more ram and better video card, video uses a ton of resources. The hard drive issue seems to start causing havoc after its about 1/2 to 3/4 full.

Hope this helps.

[crabbywelder]

Sorry I'm in Canada. When is Memorial day.Ima getting anxious to see you complete your masterpiece!

[tbone9873]

Are you going to put rear steering on it too?

[rcWizzard]

@tbone9873

Doubtful, depends how well a front axle with drive and steering turns out.

[SumDumGoi]

You Sir, are the Norm Abrams of model building. You da man!

[vampirefreakliverup]

love the work you put into this an your results... makes me want to hook-up ol' machining hook-ups(lathe, mill, etc.) and see what i can build?.... 1/4 scale '68 firebird??? you rock! love the work an waitin 2 see final product....

[crabbywelder]

hey that is very cool id love to see it working. I'm a welder fabricator ,my dad is a tool & die maker I can apreciate the work you've put in to it. looks great

[rcWizzard]

@crabbywelder

Thanks man!

[GM5778]

LOL I love the little wood wheel chocks!!!!!!

[333bigjoe]

when is part 17 coming out?

[rcWizzard]

@333bigjoe

hope to next weekend. 3/21/10

[austin6167]

hey how much would it cost for u to make me o??ne of those

[rcWizzard]

@austin6167

Around 10K, plus your engine.

[austin6167]

sorry if i had 10k i would but i dont have that much thanks eany how

[mindricofox]

i want too see it workig

[rcWizzard]

@mindricofox

Me too.

[riverhawk4488]

im sure youve already got your brakes working properly. but what if you made a brake system like one where the disc brake actually comes straight out the back of the axel?? just a thought.

[meaghanbeast]

hey does this truck run

[rcWizzard]

@meaghanbeast

The Truck, no.

The Engine, Yes. Check out video part 1.

[MrChevy369]

they make disk brakes for bicycles, i dont know if you want them to be scale though, because they probibly wont be. ive been watching your vids ever since you put the first one up. let me know when its done.

[rcWizzard]

@MrChevy369

Subscribe and Youtube will let you know when I post new video's.

[crabbywelder]

this is the coolest thing ive seen in along time. I look forward to see your truck run.

[novakandnick]

Can you make a little vid in action

[rcWizzard]

@novakandnick

It will be a few months before drivable.

[shadynebey]

Full scale monster trucks don't have brakes on the hubs, they have brakes on the propeller shafts on the differential side. May be a bit easier to manage that way, not to mention takes care of your space issue.

[rcWizzard]

@shadynebey

Watch video part "16 Again" , skip to 4:30.

[Helgso]

It sucks near the end where the camera starts to jump between frames ...

[TheChevyman360]

how much would just a frame cost and how much would just a set of shocks cost

[TheChevyman360]

how big is your servo and how much horse does that engine put out and how did you get the diminsons for the frame and your truck is so awsome I want to build one for myself but I dont have the money and HOW MUCH LONGER TIL YOU CAN DRIVE IT

[rcWizzard]

@TheChevyman360

This isn't the kind of project you throw money at and it happens. You have to make it happen, be able to fabricate parts, cut, bend, weld etc.

It will be a few months before drivable.

I used a 1/25 scale Revell Model for the dimensions, kit # 85.1901

[salemcripple]

Why not put a single disc brake on the drive line(s) like the real one has?

[rcWizzard]

@salemcripple

Watch video part "16 Again", skip to 4:30.

[salemcripple]

Ah, thank you. I gotta admit you threw me through a loop when you said "watch video part "16 Again"", and then said "skip to 4:30. lol, i thought you were telling me to watch THIS video again, and skip to 4:30. Which of course it doesn't have. But i found it all right. Awesome build by the way!

[Spd868]

so im going to mortgage my house for a truck like what what dealer sells them lol? :-)

[rcWizzard]

@Spd868

No dealer, It's scratch built.

[techno5213]

its coming along nice

amazing!

[magicmechanic86]

that servo is beast!

[rccardude04]

Correct me if I'm wrong, but don't the real 1:1 scale trucks have the brake disc on the driveshaft going into the front and rear axles?

[rccardude04]

As it turns out, I didn't watch everything. I now know the reasoning.

[offroaderkid]

@rccardude04 hey if u think u can do better send me a vid this is awsum work respect it !

[rccardude04]

Wow, you're a smart one. I was simply making an observation that was retracted when I saw another video. Calm down dude... lol

[wildbanchee3]

its big enough to actually ride in it

[pfereira]

Dude, try to do a twin steering servo system, this way, the front wheels can turn to right / left faster.

Good luck!

[Mudgrove]

Hey RC Wizzard,

Hats off to you for going the hard yards with this.

It's coming along real nice mate.

beautiful!!

[Thebigmac135]

where can i get that engine

[sk8anSrf]

theyre pricy but you can find them at ebay or brand new at conely motors search that up i forgot the sight name

[Thebigmac135]

thanks

[rcWizzard]

@Thebigmac135

Check out the new version, The Stinger 609, that's 6.09 Cubic Inches at ConleyPrecision. com !!!

[454NitroBlock]

Very good, you have been coming along quite nicely. Keep chugging along. I need to paint my Toyota GT-1 TS020 body for my HPI Super nitro after rebuilding it.

all about having time and resonable tempratures to paint haha!

[rcWizzard]

@wafel1

Not drivable yet, that will be a month or two.

[Patternforlife]

whats all up weight at the moment?

[rcWizzard]

@Patternforlife

About 90 lbs.

[Patternforlife]

@rcWizzard

nice i am into the 1/8 scale buggys and stuff, but this is insane

[rcWizzard]

@Patternforlife

You're lucky, you can go to a hobby shop and buy the parts you need. :-)

[rcWizzard]

@robmurray12

I want to see how this gearing works out before making a Drive/Steering axle.

Check part "16 Again" regarding the brakes.

[Deathheads69]

nice work man

[themaster91156]

never mind about the straps it lkooks like you didnt anyway

[m16figure8]

so i didnt read all comments, i apologize, but if the inner diameter of the wheel is limiting brake options, maybe wheel spacers could be an option? cool truck.

[spinracing]

Might want to entertain some inboard brake rotors with splined hubs that pass the axle through.. Or you could simply broach the axle and key the hub for the brake rotor...

Or as mentioned elsewhere I believe.. a brake rotor on the pinion yoke.

Granted the brakes on either side of the diff could give differential braking if you chose to....

[rcWizzard]

@spinracing

Check out part "16 Again" .

[ootsam]

Badass! why don't you put a rotor on the driveline?

[rcWizzard]

@ootsam

Check out part "16 Again" .

[Z0102030]

I think two server is more powerful than one

[rcWizzard]

@Z0102030

You mean 2 servo's. I agree.

[themaster91156]

well how are you gonne power that i know with a battery but just one server i hate haveing to recharge dont you

[onetoughtechie]

what about a brake caliper from a moutain bike some are hydraulic and some cable operated i've seen some really small ones for BMX bikes just a suggestion your idea is good though nice and hidden. You are the master. This is the best scale model i've seen great job.

[rcWizzard]

@onetoughtechie

I've looked, calipers are still to big.

[robertjdm]

Ok! Never mind! I just saw your video "16 again"!

[robertjdm]

Could you not have put the brake rotor on the very front of the axel? (where the drive shaft goes into the axel) Then you'd have the room! Not to mention it would look nice! If you can build this tick ass truck, I know you can think of a way to do that!

[aznkid221]

im jw if you sit on it can it runn and pull you along with it if u sat on it?

[spikonaleash]

@aznkid221 thats really dumb

[aznkid221]

Hows that dumb? you can ride on it.

[torqtoyz]

very nice work.forget all other negative comments,its beautiful

[jonesm16]

i would love to see the baja 5b in action. it looks like a really good car.

[rcWizzard]

@jonesm16

Search for Baja 5B, there's videos all over Youtube on the 5B.

[PerrisJettison]

wow what a waste of money

[isantimn]

dont hate on the guy its his money..

[80MOOSE08]

i know most people aged 50 buy a boat os something lol

[thespaz24able]

are you going to paint the chassy green

[rcWizzard]

@thespaz24able

It will be Powder Coated green.

[rgishire]

Any room to maybe try a disc break set up between drive shaft and the diff ? kind of like the real grave digger has ? just an idea kinda hard to tell with out seeing it in person so if any body would know if that would work it would be U ! Have to say this is the best home build I have ever seen !!!

[rcWizzard]

@rgishire

Check out part "16 Again"

Thanks.
