One more TXT-2 "Agrios"

[Mouc-RC 530]

Few hours of "decaling" later...

Body's wheelbase is a bit off (and I still have to mount that rear steering servo "behind the axle"), but I think I'm happy, with that orange marrying the sunset light well

First time I try to accentuate the panels lines! Tough job I found, steady hand needed! Before using a thin black pen, I "carved" the lines with a self-tapping screw. Gosh, I was nervous.

Finished the body-posts, today.

Seems that Monster Trucks by Tamiya is a family affair

First Run Yesterday. Sorry for the noise of those gigantic tires rubbing wheel arches! I'll need to trim them soon. Also definitely needs a fan on the TEU-106BK. Super fun truck. Glad I have it now

 

 

Tires are Golden Years from Jconcepts. As brilliant as their price, but clearly a step above "normal" tires & foam. Also really help the overall dampening/handling of the truck

Cool thread, i built an Agrios and used the Xtreme Juggernaut behind-axle servo mounts i got from ebay, that with removing the bumpers, Jconcepts wheels/tyres and better shockies make it look so much better. It is a really cool-looking truck once you do these mods.

The servo mounts do require a bit of work to fit properly without the tie rods clashing with the suspension but it is definitely worth it. I'll put some pics up of mine later

I got the ideas to mod this truck from some of the builds i saw here, very inspiring!

The (Brother driven) TXT-2 is really a good jumper. The Juggernaut also, but it's more difficult to go straight with it

No transmission were harmed during the making of the film. Only one polycarbonate body, but it's designed for this purpose, right?

lol at the Jugg body 

 

good stuff!

Hello,

Went back to a 8 shocks setup, finally. After the last run depicted above, found out that there's a lot of stress/forces on only 4 shocks, hence they do leak a bit more than usual, and the preload collars just pop out after a few jumps.

Had to use the 18mm length spacers included with the rims instead of "normal" 11mm that 4-shocks setup allowed to avoid the tires rubbing the springs. New stance, with wider tracks:

But now I need to upgrade the front steering servo, 6kg isn't enough anymore. You never stop spending money on those big machines!

Hello!

Just bought some new tires for the TXT-2:

I like all the details & the scale look, and they're super cheap right now: 16$ instead of 35+ . 2.6 inches in mounting diameter, but oddly only 140mm outside diameter (maybe they don't sell well because of this "small" size)

As I find that 160mm OD tires (or more) are a bit hard to handle for the TXT-2, I'll try these instead.

Where did you get them?   I know a few guys who got them for that price when they clearanced them a few months back, but haven't seen any for that price since. 

[Mouc-RC 530]

I'm afraid they're out of stock, now. I ordered (08/16 in the night, European time) from their website directly, but at this price the sale must have been quite short. :/

First picture:

The Juggernaut inherited of the JConcepts tires, for a more classic look (?). And the Agrios with the new Michelin MegaXBib. Actually, they're 145mm in diameter. And super wide, wider than the JConcepts ones .

Had to widen the TXT-2 track at the time for the Golden Years not to rub the shocks/springs, now I may try to reduce it a bit as the MegaXBib are "smaller" if one can say.

56 minutes of M2.5 wrenching (and blisters on my fingers) later:

Prefer it this way (-14mm overall width)

I've enjoyed reading the custom upgrades you've made on your truck. They really look good and well made! Thank you for sharing.

Thanks! But now I need some advice from you Guys I think...

Recently updated steering servos and BTA mounting plates on the TXT-2. Drag links are much more parallel to the main steering rod, which I like from a mechanical perspective

Did not change the design much, except I added some Tamiya stars for fun, but I switched for Low Profil Sävox servos, 18kg.cm each @8.4volts.

They work great, are a bit noisy as all Sävox I know, but they're a bit hungry for the TEU-106BK BEC system of the ESC.

Would you know Guys an ESC for twin-parallel brushed motors (Sport Tuned in my truck) with a 7.2v or 8.4v BEC?

Pretty sure that the Hobbywing 880 would do the job, but the BEC output is rated @6volts. It's a detail, but I'd prefer some higher voltage, as I run with 8.4volts battery packs.

Thanks in advance for any help!

Run a HW 1080, it'll give you 7.4v BEC.  I run the 1080 on my Sport Mod race trucks - dual 17t brushed Reedy motors. 

[Mouc-RC 530]

Thanks a lot, Sir. In this case I guess I'd better prepare for some soldering and programming card buying action

I know Hobbywing is very nice especially for the price. Don't they have any worthy competitors these days?

For brushed systems I don't think there's anyone else around these days to be honest.  I use the HW 1080 in nearly everything, even dual motor vehicles.  Just requires some soldering/wiring as you said. 

The 1080 came with a program card in the past, I think they stopped doing that with the recent updated version.  I think I have 30-40 of those cards from buying the old ones. 

[Mouc-RC 530]

Once again, Thanks to Sir @87lc2. My TXT-2 works perfectly fine now, with the 1080 from Hobbywing. No BEC fault anymore.

And good news, the TFU-01 fan from Tamiya that I got previously for the TEU-106BK is a direct fit on the 1080.

Awesome, glad I was able to help!   Have fun with it!
