E-Slayer Build

[rckcrwlr]

Well, I had to take the plunge.

Was so close to buying a Slash but was not impressed with the 2wd aspect of it.

When I saw that the slayer was based off the Revo chassis...I just had to have it...there is no better suspension geometry out there...








Under the hood is a beautiful thing...yes a 3.3 Nitro Motor on this thing...

[rckcrwlr]

OK, enough of that non-sense...

Out with the old power...






IN WITH THE NEW POWER!!!!



I would like to introduce you to.......

E-SLAYER!!!!!!!!

[rckcrwlr]

Now for the build...

Doing some research on here it came down to two options with this conversion; 1 Build it from scratch like I did my savage or 2 find a conversion kit to help with some of the modifying.

Going with number 1 on my Savage created a lot of headaches, wasted funds and foolish purchases. I opted for number 2.

Now came the research time...I found out that the Slayer Chassis is the Revo Platinum Chassis so any of the Revo conversions should work.

I opt'd for Tekno due to the known quality and the use of the clutch bell set up. Plus a cool t-shirt


This kit includes a 5mm flywheel/clutchbell adapter; adjustable motor mount; battery tray; radio box; ESC mount and detailed instructions.

So to start you need to remove all the Nitro stuff from the the chassis which includes:

Fuel Tank, Tubing and Mounting Post
EZ Start and Wires
Exhaust Pipe and Hanger
Engine and Mount
Left Radio Box
Throttle Linkage and Return Spring
Receiver, Switch, Receiver Battery
Right Radio Box

Looks great, and thanks for the info on the platinum chassis, i wanted one of those for my revo, (when ever i get one)

Now you need to remove the flywheel off the engine.

The kit comes with an adapter that puts the whole clutch assembly onto a 5mm shaft of a BL Motor...



You can then assemble the motor mount. This thing lays right in where the Nitro Engine mount set. It also gives you full adjustability for most popular BL Motors up to the length of and XL (what I am using)





It also gives you full adjustability for perfect mesh setting


Once you have that set...you are home free
Install the ESC Mount



Install the battery Tray and straps


You are pretty much done with the conversion...

Looks great did you stay with the 2 channel traxxas transmitter and split the signal for the brake/esc?I will receive my Slayer this week with conversion parts etc.

I used a Spektrum DX3R just because I had it and am planning on racing it against those fume sniffers...

Now comes the electronics...
When you are running a nitro tranny you must use the mechanical brake and disable the ESC brake. Wiring is easy by using a "Y" Connector where the ESC and Brake Servo go in the two sides and you plug it into the Receiver Throttle Slot.

So I had this small ESC laying around so I figured I would use it on this project... :o

It is a little thing called a Mamba Monster Maxx (MMM)...check out these specs:


The only way to appreciate the size is to compare it. The first pic is the motor wire next to a servo wire. The second is a stock bullet plug and the one's that come with the MMM. These things are huge!!!!



It comes with a built in fan that when it is spooling up sounds like a turbine...


So she is all ready to go...just waiting on a 5s LiPo to get this puppy going...

Here is the combo that I am leaning to...Anything more than that will be uncontrollable with this rig... (Thanks BrianG)

Looks good, trying to finish up my slayer conversion. Could you tell me what color springs it uses front and rear? Can't seem to find that info...

[rckcrwlr]

Well...bit the bullet and ordered the juice...

OK..the kit does not allow for mounting the side bumper and I really want to keep it on. I notched the battery tray and Shoo Goo'd the side bumper to the battery tray. I hope that it holds.



Next thing was to cover that huge hole in the windshield to avoid material flying through. So I did what I used to with my Nitros. I used some mesh that is uses for repairing lexan and Shoo Goo'd it in place. To make it look better, I painted it red...




Now I just need to get out and test it...

[rckcrwlr]

I was able, with my daughter's help, give the E-Slayer a test run...

OMG...this thing is sick and I didn't even change the gearing...

Didn't lock out first gear and may not...in the video, when you see the front come up... that was second gear... :gum:

Also, realized at top speed the brakes needed adjusted...



Cannot wait to get on a dirt track...

I am just using the stock set up...They are adjusted all the way out...I will probably preload them a little in the front to eliminate some nose diving but the rear are perfect...it handles exactly like a CORR Truck...

Looks like shes a speed demon for sure. Great build.
