Default Technical Trail... Honcho

I'm getting back into crawling after a long break. Ten years ago I had a built AX10 that was a lot of fun, and I later regretted selling it, so after playing around with an ECX kit for a while I dove back in to an Axial.

The goal was a scale-ish 1.9 truck that behaves similar to a 1:1 wheeler. I have a built flatbed Toyota on 37s so the Trail Honcho was a natural choice. I've been driving it for a few months, starting from stock, and this is what I've ended up with. The mods aren't too crazy, just enough to improve the weak spots and increase crawling capability.

SCX10ii Trail Honcho RTR
Bobbed flatbed 30mm, added fuel cell, trimmed fenders
DIY aluminum bumper and sliders
Pitbull Rock Beasts, Pitbull 2 stage foams with an extra stage added to the rears
SSD Steel Beadlocks
Axial U-Joint front axle shafts
JX 30kg Coreless Waterproof Servo, Axial aluminum servo horn (enough steering angle to rub the lower links)
Vanquish stainless steel link set
Traxxas TRX-4 GTS shocks, black "heavy" pistons, 20wt oil
Axial white 1.13 lb/in springs front, green 1.70 lb/in springs rear
Common Sense RC 5200 2s LiPo
Stock Axial motor/ESC
Axial 12t pinion for a bit more gear reduction

It's a pretty fun little truck now! I've done a bunch of trimming/adjusting/shimming to get everything set up well and I think it's pretty dialled in for now. I'll definitely upgrade the motor and ESC in the future, but the compact TTX200 transmitter works well and is pretty lightweight for hiking around with the truck so I don't see a need to swap that yet.

I also brought the truck up to Lake Chelan, WA, during a camping trip and found some rocks:

That's about it for the way it sits now! I'll continue to post as things evolve, and I usually get a few pics each time I take the truck out.

Thanks! It's a bit of a drive to the good spots but it's always worth it for a few hours of fun.

Beautiful shots!


Nice and simple setup (that is how I like it too). Can you please tell me how are the TRX4 shocks behaving on the Honcho.


Thanks in advanced and regards from Brazil

Thanks!

The TRX-4 shocks are great, very smooth movement though they seem to stick in place a tiny bit if the truck has been sitting for a few days. Once you cycle them by hand the sticking is gone. I'm sure a bit more Green Slime would solve that but I don't really want to take them apart. Lol

One thing to note is that the shock pistons in them are the heavier damped Black pistons, which are meant for the heavier hard-body TRX-4 trucks and the generic Traxxas shock oil (which is comparable to 30wt). On a lighter rig like my 5.8lb Axial that damping is too much so you would either need to switch to the Traxxas Red pistons from a TRX-4 Sport, or just run 20wt shock oil.

Otherwise they're a bolt-on affair. Even the Axial springs fit well on them.

Last time the truck was out it yeeted itself off the top of a rock, landing 3ft down onto another rock which bent the heck out of my bumper. I managed to work it straight-ish with some mallets/wood blocks so it'll work for now. I really don't want to build another... Lol.

But the bigger update is that I reconfigured my shock towers and mounting for better uptravel and motion ratios.

On the front, I moved the upper mount locations and added an aluminum brace. I couldn't do much else as the steering would bind with any additional uptravel (hey, kind of like a real truck).

For the rear... The towers are now swapped left to right which gives better angles. This also required changing the body post setup and new holes in the body. The shocks are now mounted to the lower link mounts which places the axle in a good spot for good uptravel while not hitting the frame/body. Add another aluminum brace and that's a wrap.

I think this setup will add some stability under flex, at the expense of a slightly lower belly.

That's excellent advice/information. Agree 100% when it comes to SCX10ii.

I've looked. Is there a source to buy those red pistons separately?



Is the difference three holes versus two?

I'm running very thin oil which is working, but I fear it will seep out faster than the thick.

Thanks

The TRX-4 shocks have different pistons, they don't have holes but instead have slots on the edges. These are the black pistons (in a rebuild kit):



And these are the red pistons, Part # TRA8261. They have larger slots to allow more oil to flow through:

Got some crawling in today at the usual spot. I like testing changes in the same location as I know how the truck has performed on certain lines recently.

These changes were... Awesome. The rear end is a lot more stable under flex while climbing, resulting in more traction. One side effect: more torque twist than the truck has ever had before. I did notice the lower belly and sliders as I was sliding on them more than usual. Still worth it!

Awesome, I'm curious how the damping compares to the black pistons. It will definitely be lighter. How heavy is your truck?

Good question. Not as heavy as my friend's TRX4 Bronco, I know that.

Trailed today with Losi 15wt in the rear. Still seems too stiff.

6lbs battery included using the not very scientific bathroom scale method. The one where you step on and off, with your baby in your arms and then without.

The LHS says the red plungers are going to take six to eight days (cue the Madagascar penguins) and I'm impatient. So I carefully enlarged the existing plunger slots with my Dremel (actually Ryobi) to roughly double.



Same oil, ten times better performance. Don't even need the red ones anymore, but I will try them and compare, for the good of the collective forum knowledge base.



To reiterate: 6lb rig, 15w 104cst oil, GTS AL shocks, green Axial springs. Rear only, so far. GTS shocks on order for the front.

Minor update, with a couple recent crawling pics.

The TRX-4 shocks have nice preload collars that spin smoothly... Too smoothly apparently. They loosened up after a couple runs causing less preload on the springs.

I gave each one a blob of RTV sealant to hold them in place. It seems to work so far, and will be easy to remove if I want to change the preload.



And some pics when I got out on the rocks this week. I gotta say it was a good day.

UPDATE

The red plungers having arrived, I expected to see bigger holes/gaps, but they appear to be smaller in diameter is all, allowing fluid to flow more freely around them. I would have thought smaller pistons were not viable, since the plunger sliding along the inner wall supports the rod, but if Traxxas say it's okay...

Anyway, red plungers at all four corners now and 15wt 104 cst Losi oil. Green Axial springs up front and white out back. I didn't have to do the trick where you back off the lower cap, add spacers, secure with tape, etc.

Bottom line, I dunno if Traxxas makes good crawler shocks, but I have an awesome Baja truck now. My Comanche floats over rough ground at top speed (3S) like a big ol' Cadillac.

And I'm kidding, it crawls beautifully with the new suspension.

Lastly, the plastic Axials in the obsolete parts bin look gross by comparison.
