You should have seen em before I cut them. Well, I guess you can, a few posts up.

Thanks. It's finally getting some time devoted to it.

Will do, scratching my head on mounting the upper rear links now. Having to research rear 4 link trophy truck geometry.

[Szczerba]

Rear mounts for upper links and lower links. Took some 1"x1" square tubing, cut it down the middle and pieced it back together with some TLT mounts inside. Used a small flux wire welder. I am slowing teaching myself.
I will tie them into the cage and transmission. These two little mounts took about 3 hours to make.

There will be some clearance issues with the driver's side mount. I will cut one of these down to clear the spur/pinion. Start the install soon.

Nicely done!

But what is the purpose of the tlt bracket?

Thanks.

Pretty much used them as a template to get the correct width for the rod ends. There is no way I could have made the mounts correctly without them. It would have taken several attempts to get the correct width. I am not a detail guy and don't measure alot of things.
I don't have to use them but there is no play with the rod ends in there.
I will have to use some small spacers on the upper link mounts.

I believe the engineering term for those are "tolerance correctors".

All you need is some digital calipers and a deep appreciation for the metric system. Makes life and fabrication soooo much easier.

I have digital calipers but "ehh good enough" works good too.


worked out the rear link mounts. I'll have to box in the one I cut down. I plan on incorporating the cage into the rear link mounts. Still deciding on that layout. Have to tie the front part of the cage into the front suspension too.

Rear upper mounts on the axle might be too high right now.

decent sized lipo will fit.

Good call tying the mounts in with the cage. I can see them getting tweaked.

What size lipo are you going to run?

Yea, the steel pan isn't very thick either.

3S or 4S. Not sure on capacity. Have to do some measuring once I get the cage all done.

You know of a source up your way for 3/16" OD, .030" wall steel tubing? I need a couple feet.

Food for thought: I killed a 2200 30c 3s in my brushless Slash. I'd stuff as many mah's in there as I could or find a stupid high c rated battery if you have to go small.

I don't know of any offhand, probably could order some from a welding shop. What is the OD of 1/8" brakeline?

Yea, the final battery size is still not figured out yet. I'll decide on the lipo setup then. Big pack or two medium packs together.

Found some 3/16" OD , .035" wall steel tube from aircraftspruce.com. I'll just get it there and have to wait on it.

That's only 66amps man. Something around 120-150amp on the low side should get it with all that steel/alum and that novak motor.

Slash is lookin good man. I'm liking the chassis and cage. Please get some video when done!

Will do.
The truck right now is 6.5lbs. And I don't have much more tubing, probably 1-2 ft, to add. And then the battery, body and esc.

Yeah I know. Didn't say it was smart, just that I did it.

Thanks. You'll be the first to know, if do!

Deciding on a battery(ies) right now.

I can run two 2200mah's 3s or one 4000mah 3s. Both claimed 40c.

The 4000 would be a little bigger in the chassis, I would have to extend the rear tub about 7 mm on one side but it is 1 oz lighter.
Might mess with my chassis/rear link mount support plans though!

Or I could go with the two 2200's stacked. The COG would be a little higher and they would weigh 1 oz more but I would have 400mah more.

Cell phone pic of two 2200mah's stacked.

oh yea. ooopppsss..
You and ballin' might have to arm wrestle for it.
I should rename this build the Tuffguy, Ballin' and Szczerba's 2x4 to 4x4 Trophy Truck Build.

I am just waiting on the 3/16" tube to show up. Should be tomorrow or the next day. Ordered two 2200mah 3S 40c lipos tonight.
