Traxxas Evo8 (1/8th buggy)

Thank you, I have seen that before and have read thru the whole thread. I have been looking a pictures and such from it for ideas. I found a link on there that sends you to a shoot-out that a online mag did and his truggy did poorly against the others. Then again it didn't have sway bars but it still means that I have alot of work to do to try and get this thing competitive. Cabbie did have an advantage on me... he has a mill while I just have hand tools but I do my best with what I have.

I saw the thread with cabbies truggy . That thing looked AWSOME .

I used to do that mod when I was shearing the 1/8th hybrid revo diff outputs or you could use these with stock centres:

Rchippie: Yea it was a pretty good looking ruggy/truggy.

Arct1k: Haha well those would have saved me a couple hours.

As far as updates goes I drew up a chassis design and my original layout idea.. would have made the chassis way to wide and heavy. This is the layout I was originally going to use..

I liked how all the batteries would be mounted on the chassis so that the COG would be low but it would have made the chassis way too wide. So after brainstorming layouts I found the layout that I believe I will be using..

Even though the COG is higher the batteries are closer to the center. This makes it so the higher COG doesn't matter as much. This will allow me to use stick packs and it also makes it so that my chassis can be slimmer cutting down on weight.

I'll be getting a final design done for the chassis today and hopefully cutting the chassis today to but that might have to wait till tomorrow.

Bulkheads and Chassis

First off today I cut the Bulkheads down so that the electronics and batteries could fit in.Before I cut them though I measured how far it was from the center of the Rocker post to the shock mounting hole. Then I got out the scroll saw and hacked away at the Bulkheads.

After I got those cut I finalized the chassis drawings. And taped them to the piece of 1/8th" 6061-T6 aluminum.

After a couple hours of cutting and filing I came out with this..

For cutting aluminum for the first time andonly having hand tools I think it came out good. But after cutting it I realized the parts where the front and rear of the chassis hook on are probably too thin. Unfortunately, I don't have material to make another one so this one will have to do for now until I get some 7075.Then I will put the diffs on risers so that the front and rear can be wider. I still have some more filing ,drilling,and bending to do but here is how it should turn out and how it looks right now.

This last picture is just to give you an idea of where the batteries will be going. Obviously they aren't going to be the actual packs that I will use. I plan on using some lipo 5000mah 7.4v packs.

Today I'm going to try to finish the chassis and mount the diffs. I will probably also start drawing the battery mounts and the shocks/chassis stiffeners too. Watch for updates. Actually I created a website for projects..
www.Teamkassanova.webs.com . There you will find all my projects and the latest updates on them (I will be posting updates first on my website)

Cool! nice updates Ethan....keep em coming!

Wow I haven't posted here in forever..moved to Mobile, Alabama and all my stuff has been in storage. Got everything out of storage and I have been able to work on this project here and their and I thought I would share.I have mounted the front end and rear ends and made the upper plates for both. I also got a battery tray mounted and to hold the batteries in it will use two velcro straps like the one in the picture. I'm very excited about how this project is turning out..:nod: and I haven't even gotten to the bodies, wheels, or tires. I will let the pictures speak for themselves..



Next, I will be ordering a Rc8 servo saver to complete the steering and some Revo drive shafts to cut up and put in the center to link the center diff to the front diff.

Nice work there!

I'm curious to see how this all plays out. The one thing I personally try to do on any conversion is minimize modifications to stock parts. That way, when/if something breaks, replacing it is a drop-in affair.

Brian: Thanks

Yea this project I have been trying to keep a lot of the stock parts on it. I think I have been successful where the parts will break the most.

Made a discovery today.. the stock rc8-e motor mount won't work on this because I want the motor positioned on the left side and the motor mount would put it on the right side so I will have to use a Tekno mount or a novak mount. Or I could move the battery to the right side and the motor to the left side. This would mess with the steering though since the Rc8 steering puts the servo on the right side. and I rather just use a different motor mount.

[nitrostarter]

Most buggies and truggies have the steering on the right side. Almost all of Mike's conversions have the steering and the motor on the right and the battery on the left. Itsa good balance.

nitrostarter: haha exactly.. which is why I need a different motor mount so I can keep the motor on the right side since that's the side the servo will be on and then keep the battery on the left as described in my last post.

WOW blast from the past . I forgot all about this thread . It looks good so far .

Rchippie: Haha thanks

I got the steering set-up and the mud guards in the mail. I decided to not put the mud guards on until I get the body to make sure I place them so the body fits tight. I did however mount the steering and it fits very nicely. I had to trim the bulkheads slightly because of clearance issues and had to move the steering rack from the tops of the bell cranks to the bottoms. It looks like this will provide good steering geometry. I'm very happy how the steering fits into place.





I'm awaiting the Revo driveshafts so I can cut them down to make the center shaft. I also purchased a used Tekno 36mm motor mount for $12 that should be here later in the week.

After a busy week of school and soccer and getting a job at a local movie theater.. I made some progress on the Evo8. First I cut up the Revo drive shafts and put a male half shaft in the middle of two female shafts to make the center drive shaft. Then I cut up the Rc8 steering top plate so the drive shaft could fit. I also had to grind a slot in the bulkhead upper deck because of drive shaft clearance issues. After I got the center drive shaft taken care of I took the parts I had used from the Slayer drive-shafts on the center diff and replaced them with the new Revo drive-shaft parts so that I had complete Slayer drive-shafts.

I got the mudguards mounted and had to cut down the chassis slightly in the front to make them line up. I think those turned out great.

Next, I mounted the Tekno motor mount by drilling slots in the chassis. As you can see from the pictures its alittle crooked so I will have to fix that with alittle bit more drilling.

Lastly, I got a piece of black vinyl from a teacher at school for free and decided to try wrapping the chassis in it. Its a little bit shinier than I would like and also has quiet a few air bubbles in it. I figure you won't see too much of the top of the chassis once all the electronics are in place.I didn't wrap the top decks yet becuase I'm still trying to decide if I like it.. what do you guys think? I know on the bottom with the vinyl or with it I will probably be a lexan chassis guard and so I really wouldn't need the vinyl on the bottom since I would paint the chassis guard black.







I also just ordered some 17mm adapters from a guy used for $7 shipped. He isn't sure what brand they are but he says they will fit so I'm hoping they will do.
