This arrived today,

Difference between the stock and aftermarket end bell.

Another shot comparing the two.

End bell installed

Fan and cover

Installed and fits

Everything back together

[akrimmel]

Not sure how much this will help, but it moves some air.

[akrimmel]

Not sure why my words are so small

[akrimmel]

[SIZE=7]
Anyone I changed the size of the font

[akrimmel]

Maybe this fixed it?

[akrimmel]

It takes a little finesse to get the battery cover to fit

[akrimmel]

More parts on order, gonna bash until then.

[akrimmel]

Orange wheel nuts dont fit, too small.

[akrimmel]

Sucks they dont fit, they look nice. Will source from somewhere else.

[akrimmel]

Anyone else order them and have them not fit?

[.AJ.]

You need m5 nuts

[akrimmel]

I believe I found the right ones.besides the ability to make my text bigger

[akrimmel]

Why do I have change the size everytime?

[akrimmel]

So its appears to be fixed now.

[akrimmel]

still having to change it everytime

[.AJ.]

How long a runtime does the 9000mah give you?

[akrimmel]

How long a runtime does the 9000mah give you?

I could answer that question if I knew, and what I mean is I ran both of my 3s 6500's and upon using the 4s 9000 for the first time after about 20min I blew a wheel nut off and the hex bolt holding my upper limiting strap backed out as well. I was at the park from my house where I bash and no tool box with me that is why I don't know. I will go to my LHS to get the wheel nuts and I have hex's for the limiting strap. Wont be able to try again until Tuesday AJ.

[akrimmel]

I also went from the stock 27t to 31t pinion and I was still only getting 33-34mph, the limiting strap hardware must have already backed out, but I thought it was from the ground as it rained yesterday and the ground was still soft because it was burning out more than usual, just thought it was from the 4s. On another note the rear end temps were down literally 100degrees, the Udder Butter did its job, so that issue is fixed. Also I got the driveshaft rub marks from the GPM Brushless fan setup so I will take the fan and the shroud off and leave the GPM endbell on as its twice as thick as the original and its aluminum vs plastic from the stock one

[akrimmel]

These came I today

Rear upper suspension tie rod, they are almost twice as thick as the stock. Should help with some anti sway I hope as I'm waiting on aluminum front/rear sway bar rod kit.

[akrimmel]

I also have this for cosmetic and added protection for the motor/esc wires.

When I get the rear tie rods installed and the mesh wire protector I'll post the pics.

[akrimmel]

Today was a good day for parts,
These shocks look sick in person.

Aluminum servo arm

And tire bands to reglue these tires


More shots of the new shocks


Just the endbell on, took off fan and grill

[akrimmel]

So after putting on the new shocks, zipped her up and went to the park and this is why I came back home in less than 5min

Another shot better view

I turned it on got everything up and started to drive and it was turning left and right, once I got it on the grass is when it started locking out again, but permanently as in the above pictures. I guess I should have changed out the servo arm I may have noticed this, and yes I turned it off and on a few times to try to reset it with no luck. I will deal with this tomorrow, worst case I put the stock back on until I can decide on a new one.

[akrimmel]

On another note these shocks make a huge difference in the stants of this truck, with the old shocks I would drop the truck from my waist and it would bottom out with the new ones they are sturdier and when I drop it sticks and stays high like monster truck. 80wt in shocks 60wt in the rebounds.

[akrimmel]

came home today unplugged the servo and reset the alignment of everything and all appeared fine turned like it did when it was new so I went to the bashing spot. Drove fine for a quick 30sec and locked up to the left again and couldn't come back out of being locked. Went back home put the stock servo back in and went back to the spot. It handles so well with the new shock setup and when it lands it's like on pillows, doesn't bottom out when it hits the bottom of the ramp stays just slightly compressed and lifts off perfectly. I do have the actual shocks (front green ones) adjusted about a inch down and I will take that back out, makes it a little too light in the front. The front wheels want to lift a little while turning. So now that is taken care of I will take this offline for a few days, bashing that is as I need to do some more upgrading massive part shipment today and I will take the stock back out as a spare and wait for the waterproof servo to come in from power hd.
I will take installation pics of all the following.

[akrimmel]

Aluminum steering servo, front axle carriers and rear axle C hubs, no part numbers for the steering servo or the rear axle C hubs.

Metal front chassis protector

A better shot of them

Hardened front and rear driveshafts, new wheel nuts, and some NOS tanks.

New front bumper

Rear bumper with a slight wheelie bar

Aluminum toe links, not sure where these are yet

Some decals for the rebound shocks

Antennas from RC MART, one at a time.

[akrimmel]

This will keep me busy for a few days still waiting on a few things yet as well. Will also put In the 47t spur since the transmission will be apart for the driveshafts.

[akrimmel]

Bottom stock 51t above it 47t final spur for this transmission

Shows the 47t spur installed and re-lubed with udder butter, also put it in the gear cup behind the spur gear.

A shot of the new front driveshaft

That's all i did today as far as upgrades, didn't reinstall transmission as I have other parts to put on and it makes the truck way lighter turning over etc.

[akrimmel]

I did notice that when I went to remove the internal set screw that holds the shaft onto the transmission shaft, I didn't have to break torque on it and it was already a couple turns loose. Has Anyone else that swapped front shafts notice this? Even though the screw had that hardened thread locker on it I still put on medium (TL) before I installed it.

[akrimmel]

BTW if I knew how to post a video on here I would show the aerial assault that involves my POS savox 1230sg, a artillery shell and a crap eating grin on my face as it soars to new heights one last time. RIP 1230SG.

[akrimmel]

Here is the bolt that holds the driveshaft that was loose on the stock shaft

[akrimmel]

New front axle carriers, I do have anodized calipers on the way

Installed on both sides

[akrimmel]

The rear axle C hubs as well

[akrimmel]

I have all new anodized servo arm, and the steering assembly which I'll replace tomorrow, maybe a bumper or two and the rear diff skid plate from T-Bone Racing.

[akrimmel]

Rear diff skid



Orange sleeving on the motor wires

[akrimmel]

Steering assembly and servo saver, was having issues with CVD axle pins coming out behind the wheel hexes where they go in behind the front axle carriers, so no true pictures of the assembly


And the new servo to install tomorrow, maybe even a test drive

[akrimmel]

Shout out to WRESTLMANIA!!
First time with the body on to show the ride height. Also there's a few updates, but like I said its WRESTLEMANIA, been watching for over 34years now.

These came in today, but will have to wait due to some bashing injuries.

1st yesterday I replaced the steering servo assembly and the
Front Steering Toe Links and the servo itself. Where the to connect to each- Front Steering Toe Links and the servo assembly were rubbing and not letting the servo swing to its fullest extensions. So I had to file both sides of each to allow full extensions. I'll have pics of this tomorrow as well and while bashing on my 1st 3s today the temps were about 125 and the rear driveshaft was hot but not the rear diff. So I kept driving and put in the 2nd 3s and was jumping great and landing most. Temps were 130 and kept driving. I put in the 4s temps went to 140. I changed the spur gear prior to this bashing from 51t to 47t. After about 10mins with the 4s I noticed there was a loss of power. Upon walking to it, applied throttle and only the front were turning, picked it up and the rear driveshaft that connects to the transmission melted off just before the pin. I know the issue is in the transmission, just not sure because all was fine after the spur change manually anyways. I'll have pics tomorrow of the problems. Also the front swaybar where it connects to the frame came off, but I didn't see it until the driveshaft twisted off.

Have taken a break from the UDR, had to bash the summit a bit before it gets hot here.
