Is a Yeti right for me? (Plus Intro)

Background:
I got into the RC hobby within the last year. A buddy of mine got me into it and I ran out and bought a Traxxas Rustler. It didn't feed my itch. So I did some research, mainly focusing on Traxxas at the time not really knowing to much. I ended up buying a Slash 4x4 Ultimate. It has been a great truck, but I have already basically replaced everything. I only bash, I do not race (don't have the time or money for it really). Has time has went on and I got into the hobby further, I realized there are a hell of alot better options out there than Traxxas. But this is after I have already upgraded my Slash 4x4 to be more than your standard slash.

Current Trucks:
Traxxas Rustler (6yo Son's)
---VXL ESX and 3500
---A few RPM Parts here and there

Traxxas Slash 4x4 Ultimate (my truck)
---Castle 2400kv w/ MMP
---MIP X-Duty CVDs
---TeknoRC BigBone Center Drive Shaft
---RPM A-Arms, front bulkhead, nerf bars, shock towers
---SCTE Shock Springs
---T-Bone Racing front and rear basher bumper
---STRC Motor Mount
---ProLine Bead-Locs

----Geared for about 50Mph on 3S (21/50)

More Info:
I have learned alot as time has went on and I read over the forums, do research, watch reviews. I know a few things about the type of vehicles I want to add to my garage. I know that if I ever get into racing I will be buying a TeknoRC SCT410 or EB48.2, and I know in the future I will only be focusing on Kits and not RTRs.

Since I don't have the time to race, and I really only bash at parks and such since I only usually get together with my buddy to take out the RCs once or twice a week, sometimes we can only run one pack sometimes we run 2-3 packs. A few of the places that we go are very rough, while my Slash is at home at a BMX track for the big jumps, or even in a night flat park, it just doesn't have the ability to adsorb the terrain at one of our favorite spots. It is this failed dirt construction site that people usually run their ATVs and Dirt Bikes, so there are alot of ruts, rocks, drops, mud bog trails, etc

Onto the Yeti:
I will be keeping the Slash, it has alot of dynamic uses:
--Speed Runs
--Lower it and have fun in a parking lot with road tires
--Make or buy some tires and drift
--Still great for huge jumps and big bashing

Looking at the recent announcement about the Yeti Kit, seeing and RTR in person, and watching some of the videos. It feels like it may just fit what I want to do.


So my plan is to start of with picking up the Yeti Kit when it is released or shortly after. And building it up as things break or become weak.

My Starting parts list:

I am planning on waiting to buy the Tekin Motor/ESC, I will start buy running it with the 2400kv out of the slash and MMP+BEC. This will also be my first controller purchase so I will be also be switching the Slash over to the Spektrum system as well with a 2Channel Receiver.

Questions/Goals:
1) I would like to try to get the Yeti to run 35-40Mph on 3s (should a 3000kv motor handle this?
2) Should the servo I picked be up for the job
3) Anything I should plan on upgrading or replacing ASAP?
 
Try using the mmp and the pro 4 HD. That's what I use and it has more than enough getty up. and your already half way there.

Speed✅
Torque✅
And that servo will work good. It's the one I use. You will also need a bec for the servo.

First upgrade is probably gonna be the steering rack or knuckles if the kit dosent have an upgraded one.

3 cell for that motor is perfect. It will run cool and efficient.i would stick with the rx8 as it was designed to go with that motor.
 
The mmp is mostly a cheaper option a lot of us go for when spending the beef of the $$ on the pro4hd.

For upgrades I would add, castor blocks, vp rack and posts. Possibly wheels and foams as well. Then just fix the stuff that breaks as you go.

The yeti is a blast at a construction site, takes blunt hits against dirt piles very well haha. I'm in love with this rig just for the fact it is a very well rounded rig. It does a little of everything.

Here's a little video

I am thinking about picking one up here within the next month or so. Everything I read and look at seems like it will fit my needs perfectly.

I won't be doing a full on build like alot of people here, I am just going to keep focused and build certain areas as I go. I am going to focus on replacing the items in the front to tighten up steering and durability, as well as the trailing arms first.

After doing research I am having a hard time deciding between:

Castle MMP + BEC or Tekin RX8 Gen2
The plan is to run it with my Sensorless 2400Kv at first and then later throw in a sensored Pro4 HD 3000Kv

Also when it comes to waterproofing, I know that neither the MMP or RX8 Gen2 are waterproof and I believe the Sensorboard on the Pro4 HD isn't either.

I noticed the mmp has an adjustable bec ,up to 7v. I already had a castle bec. So I disabled it not knowing. I would be interested to see if the mmp can handle the savox servo by it's self.

As for the water proofing your right the tekin esc/motor & the mmp will need to be w.p.'d
 
I wouldn't attempt to run the Savox without an external BEC my man. I speak from experience. "thumbsup"

Savox servo's are voltage robbing, power hungry little demons, lol.
 
Also when it comes to waterproofing, I know that neither the MMP or RX8 Gen2 are waterproof and I believe the Sensorboard on the Pro4 HD isn't either.

I recently waterproofed an MMP and Tekin Pro4. I followed the video that Harley had done and improvised a bit on my own. It's really pretty simple and seems like it should be as secure as it can be. You'll just need the conformal coating.

The sensor port and empty screw holes were slathered with some silicone with the harness in it. Just make sure it doesn't push down too far into the screw holes and effect the motor. A limit,e dab "l do ya. Makes the sensor wire a bit messy to remove, but I'm ok with that trade for the protection from moisture.
 
I conformal coat my mmp's and the soak them in corrosion x just in case i didnt get it in all the nooks. As for the motor I soak the sensor board in corrosion x and let it drip dry overnight then I seal up the motor face plate and rear plate with a touch of silicone. Once its reassembled I fill all the unused motor mounting holes with grub screws and lock tite. Once the power wires are soldered to the motor I coat the connections and the area on the motor that the board sticks out with liquid electrical tape. I try to fill the gaps at the motor housing where the power posts pass through then I turn it upside down as to not get the stuff draining down into the motor. Ive done this on everything ive built and glad I did because we had a g6 with a ton of river crossings and rather than wait for the bridge to be clear I drove around it and usually submerged it in about a foot of water half a dozen times without issue.
 
My buddy grabbed me a Castle BEC for christmas. So I have decided to run the MMP+BEC with a Tekin Sensored Motor. At first the truck will be ran with a Castle 2400 just til I can grab a nice Tekin.
