chevy prerunner/trophy truck build

[black-hawk]

Alright well we are gonna take this build a new route. For anyone who has seen cyconxc's trophy truck I am going to build something similar to that.
.
Waiting for my sheet metal to come to Home Depot but in gonna use a 16gage steel sheet for the bottom bash plate and for the rear end.
.
Gmade piggy back shocks
Castle creation 6900kv 4pole sidewinder 3
Traxxas slash 2wd front end
Wraith rear axle and transmission.

 

[black-hawk]

We'll got the front mostly put together. And Tare down is coming along about to have to buy a 1:1 car so I don't know if new parts are gonna be coming anytime soon.

Same work me man. These full-sized trucks are expensive!

Just about to got this one to paint ($900, and that if cheap!)

All right well got some progress. Got the rear axle all done just need shocks and pinion gears Wednesday when I'm in town I'll go to my hobby store and get a small one and a big one start with small get an idea of speed and heat of the motor and then see from there.

Front end is all done just need shocks and to figure out exactly how I'm gonna mount the body in the front. Got all the electronics mostly done they are running started the motor for the first time.

Since it's 2wd and these rims are weird and don't use hex's I just put it out side of it to make it wider.

Took the axle apart re greeced it with some waterproof Greece on the diff.

Just cleaning stuff.

Got me a 12x24" 16gage steel sheet for the chassis.

Got my lower suspension arms in today they are gonna work great and they look amazing and they where cheap.

Pretty scale.

Somewhat mock up. The battery is gonna be right over the back axle in the metle. I am hoping by putting the battery over the back it will keep traction better! Hopefully it won't wheelie like crazy. Really hoping this thing is gonna be freaking fast.

How she sits for now. Ran out of time today. But this weekend I will try to make the cardboard mock up of the cassis so all I have to do is cut the metal drill the holes in the same spot and she will be ready to run. I will need to paint the metal I am thinking of making it black i saw this and fell in love.

I want to make it exactly like this. Without the bypass it's gonna be black with the coil over though.

Rc4wd steel shaft

Update. Started making a mock up chassis. Also ordered the gmade piggy back shocks. I'm really excited to see how they perform on a trophy truck. From what I'm lookin at it is looking like I'm gonna have 3 inches front and rear. Kinda limited on travel in the rear u ordered the 103 for rear and 93 for the front. 103 is the biggest they had I really wanted the shot to have 2 inch stroke but it only has 1-1/2 so instead of four inches of travel I got three but it's Allright. 3 inches will be plenty.

It's coming along hopefully I'll have it fineshed in the next two weeks have it drivable. I'm gonna see if I can make a roll cage out of shoe goo and thick coat hangers i don't know we will see how it goes.

 

[Seanycool]

If you're using the wraith axle, you might want to watch out how much travel you give it. Unless your driveshaft is super flexible, you might have pinion angle problems with too much travel. Good luck on your build!

We'll went to my hobby store today bought longer upper links and pinion. My gearing now is 76 tooth spur 31 tooth pinion and a 6900kv 4pole engine I am gonna have to keep a close eye to to temps on this motor first run. It should be fast as lightning.

.

.

.
I'm gonna do spair tires like BJ baldwin's trophy truck. Like this.
.

These are the tires in gonna use for spairs. Not actually for rc though.

.

.
Gonna cut the body on the red line and then make the sheet metal as far out as I can. To the bedsides. But it's only gonna go out as far as the shocks unless I bend it still haven't decided on that.

.
Already have it on outside mounts can't wait to get my shocks in.

Thinking that for the rear mount in gonna use a Hollow metal toob and use it like an a audit pipe stilling three the bed side and then stick a clip threw it.
.

.
Thinking I an gonna try to make the roll cage with thick coat hanger and shoe goo.
.
If y'all have any advice let me know won't hurt. "Thumbs up"

Where did you get the lower suspenssion arms from and what are they made for?

 

[black-hawk]

Can't wait to get her up and running.

 

[black-hawk]

They are off of an hpi mini desert truck. I don't quite get what your asking when you ask what they are made for. It's a lower link but it has a section in the middle cut out to bolt the shocks into it. Because the geometry having the shock further up the link allows you more travel with a shorter shock. It pretty much gives you more wheel travel then it directly bolted to the axle. If you have a 103mm shock that you bolt directly to the axle you will have more travel if you bolted it into the link like that. You will see when I get the shocks.

 

[black-hawk]

We'll shocks should be here by the end of the week. Cut the body last night. Here is what I am thinking for the back end.

not much progress just been fiddling with little things measurement for the metal placing everything. It's gonna be hard for the rear tire holder when I'm trying to fit it and everything it's hard with cardboard so I'll probably make it a little long and cut it down to size till it works. I'm gonna have to wait to make the the chassis out of metal til I get my shocks and can figure out why I need to do for that.
.
Also I'm thinking since the space between the to sides of the chases are far apart I'll get a long screw have three nuts a screw and put the screw all the way threw both. I don't know if you getting the picture but you will see. It's coming along.

 

[K.O.M.]

I'll probably get a TON of beef for this post and please understand that I'm saying this in the nicest way I can.

I've been watching your thread (build) since day 1. I'll have to say, I like where your head is but the building is absolute junk. [snip...snip] I just couldn't hold my tongue anymore...

You are still building after all this time, so I really applaud you for that.

Again, please don't take this the wrong way, but as I was reading the ENTIRE thread, I basically have the same sentiments as the person I qouted above.

I was bit by the RC bug when I was just in middle school, so while we all know you are just 15 or 16, think of how much less access to resources I had when I was just 13?!

I would like to ask you an honest question: What is your goal with this truck? Do you enjoy the building/fabricating or do you enjoy the driving more?

If you enjoy the fabrication aspect of this hobby, then that is where there is really a major disconnect between your ideas and your ability to turn your ideas into reality. You will be short on access to the proper tools and materials to make what you envision in your head. If you look here on the forums, there are a bunch of us here that still can't make anything properly even with access to a full machine shop :lmao:

The first observation I have, and my main complaint about the younger folks I have to train at work, is the general "meh, that looks like it will be good enough" mentality. If that really is the best that you can do with what you have, then I guess that's fine. But if it's just simply access to tools and know-how, I'm sure that you can find a machine shop or sheet metal place that can help with your ideas in exchange for some grunt work like sweeping all the chips off the floor (run away if they want any type of "favors" if you know what I mean).

The second observation I have is that you are trying to re-invent the wheel. I fully appreciate that you may want to make something that is truly your own, but trust me, everything that you want to make, someone has already made it. There is a lot more to suspension and chassis design--even in RC.

My suggestion? Modify or adapt an existing design. Here's an example of a well thought out, mainstream design that you can adapt to what you already have:

Hardcore Slash G10 Upgrade Kit

Incorporate some of your ideas into this design.

That search took me about 5 minutes. That's one advantage that you have that I didn't 23 years ago--the internet. If you were, ahem, meticulous about your work methods, you could estimate the mounting locations of a lot of those components with at least 80% accuracy just from the photos alone. Your accuracy would go up even more if you went and measured some of the stock parts being used on that model and used that to scale off the rest of the chassis.

Well, I'm off my high-horse, so I'll keep my eye on this build to see where you are. Good luck and I would like to see where you end up with this truck.

 

[K.O.M.]

Something to give you some inspiration on meticulous work methods. This guy made this with NO POWER TOOLS! It is a very clean fabrication.

Look at page 14 and 15 of the thread. The bottom of page 15 shows all the tools this fella used to make his project.

Thank you for all the advice. I would like it if you haven't to go to YouTube and find cyconxc and look at his trophy truck you can look at his rigs and you will see kinda where I'm going.
.
I realize that I need better parts. That's why I decided to buy a traxxas slash front end and shock tower, and rear links.

 

[Seanycool]

Oh yeah u should follow cyconxc's trophy truck build on the traxxas forums. It's really amazing to watch what he's doing!

Got my rear shocks in today was able to get her done so now all I have to do is cut metal sheet to smuggle size. Have everything measured. So gonna get it cut up tomorrow! I'm finished with school so I have more time. Post more pictures as it comes. Here are the shock. These things are bad ass they are soo smooth.

Niiiiicccceeee! Pretty jealous lol. Why not longer ones for more travel?

Gonna be running 3 inches of travel in the rear. The 103mm which I am runnin in the rear is actually the longest shock they make. So I'm kinda out of options. Cyconxc said his only has like 3.5 in the rear and 2.25 in the front I'm gonna have 3 all the way around. I'm pretty sure that's how much idk when I get it bolted on I'll measure again but I am at max currently. Using the 93mm in the front because that's all my arms will allow I can't get more then three inches in the front which will be substantial.
.
I also forgot that I am gonna make a sway bar but I haven't gotten to that I will do that when I Finnish the chassis.
.

Now for the sketching and cutting tomorrow.
