Ford F-350 Juggernaut

[Arcocustom]

Wow Jay, that Jugg came out real nice ! Any plans to do any jumps to test out the cantilevers ?

Thank you Brian and no thank you. Thanks for the kind words but no thank you on flying it off any jumps to test the cantilevers. I have 3 Juggernaut's and 2 TXT's... I know how they behave when trying to overcome gravity all-to-well.

I stared and read about Youre Truck and its Awesome, Good Job!

Glad you enjoyed the thread on the restoration and upgrading of the 1999 Tamiya Juggernaut. Thanks for the compliments kind sir.

**2/11/2013**

Installed a Futaba receiver battery holder and power switch in the Juggernaut. Tekin suggests you do this if you are going to be running more than 8 cells or you if are using a high-powered servo. When running a separate receiver battery it is important that you bypass the Tekin Titan's built-in BEC. You can do this by simply leaving the ESC's switch in the off position and taping the ESC's switch so it can no longer be turned to the on position. The receiver battery switch is now used to turn on all the electronics (ESC, radio receiver, and steering servo) and everything operates off of the external 6 volt power supply and not the main battery pack. The Futaba 6 volt, 4 cell, dry battery box holder is secured to the electronics tray using a large section of Tamiya's double sided tape. The Futaba mini switch is mounted into an existing on/off switch mounting hole in the Juggernauts stock electronics tray.

Installed a brand new Tekin - AM Micro receiver (#TERX) for Futaba 75mhz AM radios and the corresponding futaba receiver crystal (FRC-170 FUTL49) that matches the transmitter crystal of my Futaba Magnum Junior T2PCKA transmitter. This particular model Tekin micro receiver is designed to accept a Futaba J Plug and Futaba crystal. The receiver is mounted on the electronics tray 3 inches away from the ESC and is secured using the double-stick tape that Tekin provided with the new receiver.

This truck is powered by twin Fantom Alloy 14 turn single motors, a Tekin Titan ESC, and a matched 6-cell Sanyo Nuclear Power 2000mah Nicd battery. Control comes from a Futaba Magnum Junior T2PCKA transmitter and a Tekin AM Micro TERX receiver.

The trucks incandescent headlights lights and the LED fog lights on the roll bar are still powered by the main 7.2 battery as intended by Tamiya. The lights are controlled by their own three position toggle switch that allows for no lights, just headlights, or headlights and the roll bar mounted fog lights.

Still have a few minor details to finish up. Hope to have it finished very soon though. Have some more progress pictures to share with ya.

Thanks for taking a look. - Arco​

Jay, have you driven the Jugg since you finished it? Just wondering if you get any wheel rub on the front or rear.

@th67ss
Well, with these named winter storms Nemo & Plato, I have not gotten a chance to run the Jugg with all the snow that has accumulated. No rubs to report on the body though because the Trinity shock springs are so stiff. I can tell you that the front tires do rub the steering servo mount/bumper brackets at full steering lock, but that is because I cut the steering stops and modified the front hubs to allow for more throw. To stop the tires from rubbing while making a turn, I'm using the adjustable dual rate on my transmitter to keep the throw where I need it and that eliminates any potential problems there.

**UPDATE**

Let's see now... during the first real test run I had a driveshaft drop out onto the floor afterwards, so there was a little more work to do there. Seems the 3mm set-screw on the new MIP driveshaft hub does not hold very well.​

The hubs also use 3mm set screws now which were not supplied, but luckily I had some on hand in my parts bin.

To help keep the driveshafts connected to the pinion, I took my dremel with a cut-off wheel and ground the end of the set-screw so it would have a better bite. Also applied some Blue locktite to the modified set-screw, then installed it and followed that with a second set-screw so the first one cannot back out.

(continued from the above post)

Managed to get the side-mirrors painted. Glued them together and installed them using some double-sided tape since the last update as well.

Unfortunately there is still over 2 feet of snow in the back yard so all I can do is snap some photographs...

Item #58232 - R/C 4x4x4 CUSTOMIZED MONSTER PICK-UP TRUCK JUGGERNAUT (FORD F-350)

Smashing through boundaries and breaking down obstacles, the Juggernaut doesn't stop for anything or anyone. A new arrival to the monster truck mayhem, the massive Juggernaut Ford F-350 is sure to cause a commotion. The Juggernaut is the evolution of the classic Clodbuster, with a host of new features learned from Tamiya's 4x4 experience. The sturdy aluminum chassis uses a parallel twin 540 type motor configuration and a newly designed gearbox for maximum power. The twin motors share a common spur gear. The separately available servo is centrally located in a 4-wheel steering setup. The chassis uses a coil-spring suspension system with a double shock system, 8 coil-spring dampers and 4 metal leaf-springs are used in total. The massive wheels and tires are 175mm in diameter, the Juggernaut itself is 353mm tall, 480 mm long and 372mm wide. The awesome dimensions of this vehicle are complemented by colorful stickers. Two 540 motors are included.

Along with this truck, Tamiya also announces two accessories...

Item #53369 Monster Truck Aluminum Damper Set
Item #53370 Monster Truck Light Set

... and the release of Item #17014 Juggernaut Jr.​

drill through the axle input shaft and use a pin screw from a axial kit drive shaft

 

[th67ss]

Forgot you guy's out east got that dusting of snow

This really takes the fun factor out of doing anything!

Hope everyone is doing good out that way!

@williamg
Yes sir, if the fix I just did does not hold it, that will be the next thing I do.

Well, it is the final day of March... Happy Easter everyone! March got started for my family and I with a 3,000 + mile move across America and about mid-way through the drive I was PM'ed that the Jugg had won RCMT ROM. Needless to say, this made my day. Thanks everyone.

OK, now we are settled-in, all my hobby stuff is unpacked, and back on display....

... it is time to start work on my Juggernaut 2.​

The Jugg 2 had been converted to TLT-1 axles back in 2004. They were flipped up-side-down to match the rotation of the transmission and mounted using a combination of the stock TLT suspension stays along with a custom made upper 4-link mount. Today I will be installing a stainless steel straight axle from RCP into a Dan Wyatt TLT-1 alloy straight axle housing from RC4WD.

The suspension stay mounting holes did not line-up on the new axle housing, so some customization was in order. Drilled and tapped two new 3mm mounting holes into the stays as well the axle housing.

Thanks for taking a look. - Arco​

Those rear axles from rc4wd do look sweet.

Got tired of Chaffee, so where did you move too??

Odd the tlt brackets don't line up. Nice fix

@rocpede4x4
Yes, they do look pretty neat. They are a tad bit bigger and bulkier than the stock plastic housings. They've been on sale for a while now. I needed to fill out a recent order so I grabbed a set. $45 bucks.

@william g
Thanks. Yeah I was surprised when the holes did not line up. :conf Had to break out my index, T-hanle, and 3mm tap.

Living in Washington State now. Ol' Lincoln wasn't cutting it anymore. The RI car tax proved to be a deal-breaker.

**UPDATE**

Modified the transmission in the Juggernaut 2 so the output shafts match the size of the 5mm pinion shafts on the TLT-1 axles. Removed the 6x11mm bearings, output gear, drive hex, and output shaft from the TXT-1 transmission and installed an output shaft, gear, and 5x11mm bearings from an original Juggernaut. This modification now allows the use of a 5mm yoke telescoping driveshaft on the Jugg 2.

Also replaced the soft aluminum, 18 tooth, Tamiya pinions with a pair of larger, 20 tooth, 32 pitch, steel pinions from RRP.

Modified the motor plate by elongating the upper mounting slots just a bit over stock to fit the larger pinions. A small carbide bit on my dremel was used for this task.

Modified TXT-1 transmission with 5mm output shaft and 20 tooth steel pinions.

This particular Jugg 2 is powered by a pair of matched Trinity "Monster Maxx" 23 turn, 550 motors with P-94 double shunt brush conversions.

Next, a set of #8181 "C-Drive Spline" driveshafts "for Axial AX10, Scorpion (2)" were built and installed.

Thanks for taking a look. - Arco​

The next modification made to the Jugg 2 was to shorten all the 4-link bars so that the drive shaft splines made more contact.
Below are a few photos for comparison tbetween the previous and current WB.

The Jugg 2's wheelbase is down to around 12 & 3/4 of an inch now.

Finally have all the parts for installing a Juggernaut 2 body shell. There needs to be a few modifications to the frame rails and MSC bed before they can be installed though.

Modifying the Jugg 2 framrails.

Started by masking off the area to be modified.
Next, using a dremel with a with a cut-off wheel, the stock shock mounts were removed.
A sanding drum on the dremel was then used to further clean up the rough edges where the initial cuts were made.

A couple of hand files were utilized to make the modified area perfectly flat with the rest of the frame rails.
The rails were then block sanded with 180 grit sandpaper to make the entire area smooth.

Below you can see the area of the rails that were removed so that the ESP shock mounts and tower braces could pass through.
After all the modifications were completed, both frame rails were block sanded with 400 then 800 grit sandpaper to achieve a uniform finish.

The battery tray and ESC mounting holes have also now been countersunk so they do not interfere with the ESP shock mount brackets.
Before the final installation, the frame rails were polished back to a factory molded look using Mothers "Mag & ALuminum Polish."

The stock MSC tray was also modified by removing all the mounting tabs and gluing in a patch for the servo made from the cover of the MSC.
Now there is a solid place to mount the ESC.

The entire Juggernaut 2 chassis was assembled using Tamiya's Hop-Up Options titanium and aluminum hardware throughout.

Thank you for the offer. I have a few of them on hand already but I will keep your offer in mind if I ever feel the need for another set.
