Not as good as I wanted but better then I planned.

Overall the portals and drive train held up great. I had a bad pick for tires in the rear. For this place I would go with lug fronts and almost bald lug rears or pins.

I need to rework my upper geometry though in all honesty. I did practice quite a bit at home but this traction was incredible. It caused the truck to do some wierd waves with the front. At my home spot its hard to judge the truck because Ive been going there for 8ish years. Everything is doable to me now, the truck was making Pro lines so I felt good.

But I def learned some stuff to try and am not bailing on the ideas

Shifting gears to 4wd buggy for Turf Nationals in 3 weeks and Oval in 4 weeks. Jumping back on this one once some snow falls or I find the 8th day in the week.

More weight on the front will settle it down.

That will solve it but odds are he won't use them because they're too heavy. Bob is of the (wrong) opinion that flyweight rigs are superior. One day he will see the light.

What was the running weight?

Whats the bias?

And.. Did it drive better than a losi unstuck? Lol.

My current sporty is at 4lbs. 60/40.

Hi Robbob, I wonder if how you manufactured those links? Are these just a rod with threads on both ends and female rod end screwed in? No tubing at all? If so, what material is the rod from - titanium?

The lowers are just VP Ti rods that I bent and the uppers are 1/8 Ti that I threaded the ends for 6-40 thread.

Is it much more difficult to cut/bend/thread Ti rods when comparing to alu? Do you need better tools or just more patience/effort?

Thanks

Aluminum is much easier but if you have patience with Ti it can be done.

6-32 on the uppers is easist for 1/8 rod since the diameter is closer to the thread major. 3mm dies work but it takes some time and work to do them becuase its a finer thread.

If you have a lathe you could turn the ends down on 3/16 Ti and thread them. the diameter is too big for a 4mm thread but you could do 10-24 threads.

Bending its just a bit more pressure to bend Ti but not bad.

Love this build.
I'm not so sure about the portals but the build quality is awesome!

I'm also looking to make my lower links in Ti and I'm looking to make them out of 4mm Ti.
I don't what to cut them in M4, I would rather do it is an imperial (more coarse), tread but I have now idea which one...
The 6-32 worked wanders on the 3mm Ti!
Imperial treads is like black magic to me...
Any idea on a nice size to cut the 4mm?
