E-Revo to E-Slayer conversion Project

[TruckBasher]

Ok, RCM Mike just shipped my revo hybrid diffs with lightning pro diff and got some ofna buggy diffs coming too. Not sure which to use so I got both. Shock and other chassis parts are being shipped too. The Slayer has been release just need to wait for a couple of days and I should be able to order the arms.

Now, Im on a dilemma of choosing the ESC, I got MMM on order but I you know the story of that. Do you guys think a Phoenix HV-85 or 110 with pistix can power my AXI 4120/18 and current build? this ESC is locally available and easy to purchase compared to MMM so I was thinking it would be a viable alternative.

Only problem with airplane ESCs is they don't have motor brakes. You could use the built-in "prop brake" as a drag brake, but it's just not the same.

[TruckBasher]

Yup, I read that too but SunnyHouTX was able to use it well just need to get use to it. However, know my nature I cant resist WOT so proper brake might be required

[MetalMan]

The motor required a custom shaft to work properly for this conversion:



The mounting-end of the motor will face the front of the E-Revo, and the other end will be supported by a couple bearings riding in another mounting plate.

You're the man Travis

Now this project is starting to take shape.....

[TruckBasher]

I just receive my hybrid diffs from Mike with the truggy diffs (that was fast)



Chassis and other stuff also came in (not fom Mike...sorry Mike )




(sorry for the poor lighting...too lacy to setup my flash

Now just waiting for those Slayer Arms, tires and body then assembly can start

Ohhh I still have to complete my other chassis with the motor mount from Travis

[MetalMan]

Got the drawings done, here is the pretty version:



Top left is the motor mount, top right is the rear motor brace, middle is the upper chassis brace (ties the front shock mount to the rear shock mount), and bottom is the skidplate. Also, the cutout shown on the skidplate won't actually be a cutout, but where a 1/4" deep pocket will be milled out. The skidplate will be 1/2" thick black delrin.

More pictures!







Obviously it's not done yet, but it's coming along.

[TruckBasher]

Travis, your inbox is full I cant send PM

[MetalMan]

Cleared .

[MetalMan]

More progress!






In the last pic you can see that I made somewhat of an error. To correct it I'll either cut out a lot of the delrin skid or the aluminum motor mount. But other than that, so far so good!

I can't believe I missed this thread.

Nice custom work for the direct drive. You should save some weight without a tranny. You'll want to make sure that the bottom skid plate you use mounts to the bottom 4mm holes in the rear bulks. These brace the rear bulheads and without it, the only thing attaching the bulk from the bottom is the 3mm shock mount scews. I found out the hard way that just using the shock mount scews tends to be a bit much under hard driving conditions.

I converted the RTR slayer a couple weeks ago and found I could not keep the truck from rolling like a tumble weed. Even with the Revo sway bars and camber adjustments, it was still out of control.
I have since mounted the front and rear ends to the E-Revo chassis and am just waiting for the E-Revo transmission to show up.
The stock body fits decent enough. Just trim the wheel wells a bit and ream two new holes for the rear.
I will hopefully have my new E-Slayer ready for the track this comming weekend. The lower center of gravity and longer wheel base should tame this rolling beast

[TruckBasher]

Thanks, I just thought of it but Travis made it real....

I am not sure if I got everything you've mentioned

Anyway, I have completed the front/rear bulkheads with the hybrid buggy diffs. I had to trim a bit to make it fit well. Ohh and yes there is a screw at the bottom of the bulkhead that goes with the skid..its the only think holding eveything now.since i dont have the chassis yet (its with Travis)..not sure if this is what you meant...

For the body, I have a proline hardcore truck on its way.....I am yet to buy a sway bar....

Travis, I'll PM you later...need to check with you something....

Any chance you could get a picture of this 4mm screw's location? I suppose it doesn't help that I don't have a rear bulkhead to be able to find it myself.

And a quick note, that skidplate won't be sitting so low when all is said and done...

The plan
- Make her into a mockup Slayer
- Use an Ofna GTP Porsche 911 body with stock arms maybe a Rally theme paint (body is about 13" while the wheel center to center is about 13.5"- 14" or so (buggy wheels but it will be sticking out of the body)
* or option is to get the Slayer suspension parts and Body
TBD
- RCM Revo Hybrid Truggy diffs
- Run a 2 x 2S2P 8000mAh TrueRC Lipo (4S) or fit my 5S2P A123 cells
- MMM V2 (I cancelled the order so this will have to wait)
- Powered by a direct drive to diff AXI 4120/18 (custom mount from Travis [MetalMan])
(Similar direct drive from sykeston34m)

Chassis is still being worked on by Travis so most of the parts are on hold. What do you think with the other things?

PS: Those who can help me with getting a used Ofna GTP 911 Porsche body just so I can test it, please PM me, thanks.

I did a body mod years ago when I needed a wider body...cut out the center of a clear slash body about 3 inches wide and paint it the color of the center section of your paint sceme and paint another body with a solid color in the middle and keep all your graphics to the sides. Cut it down the middle. Take the 3 inch section and mark your width. Run a bead of shoe goo on the 3 inch sections edges so the glue doesnt squeeze on to the main body. Staighten every thing out and tape it. When the glue is dry turn it over and spread the shoe goo out on both edges and bed every thing with fiberglass tape. I put in a few small screws and nylon nuts along the seam line.
