Now you just need to make some thick brass inner SLW lock rings with a coutnerbore for the hardware

Nad Why are you keeping the chassis under wraps? I wanna see what it looks like.

Thanks, Wraith knuckles have some "weird" contours, so it took some time to get them ready. But the efforts were worth it.

BTW, just waiting for some missing links and than you will see the final product. But if you know the name "Highfly", you should know what the chassis looks alike

Hello,

made some progress. Cap's on (1.3mm Carbon). Traxxas BB's made it. Here are some bad pictures:















Weight is RTR with 260g extra at the front axle. So now i need some time for testing

Greetings Frank

Awesome stuff!!! Wish we werent thousands of miles apart!!! Then maybe id see it in person one day, pics only make me salivate uncontrolably!!! Keep up the good work

[Dr.Frank]

Hello,

i followed the YTC Secet Agent treads for a while and can't resist. Ordered a SA and picked it up yesterday. I prepared the axle during the waiting time and start to put all together yesterday. The new links i made fit quit nice, but only in the front (same dimensions as Krawl wrote in his tread) fit perfectely. The rear one need some extra love, due to the fact that i use a front axle in the rear. I also put some special work on my Traxxas Big Bores to get them at 3.5". Now i would like to let you have a little look inside the dungeon of the doctor:









Max. skid clerance:



Ride height:



Full drop:



A double FXR burger with RX sauce and CC BEC made it on the Axle:



After i put all togehter i had to do a little test run in the dungeon. Now i know what Jeremy means with "suck down", man this thing is a "Sucker" (Don't get me wrong here). I just run it as it was, without any fine tuning and i'm very impressed about it.

Weight is with shaved Rovers, SLW V4's, 9 oz. knuckle weights and steel hardware 4 lbs. 15 oz. Some dietary sugar is on the way, so let see where i can put it.

Ah forgot, here are the measurements of the rear links:

Rear lower: 150mm
Rear upper: 145mm

With that lenghts it sits at 318mm (That's okay for Europe).

As far as i can say now, the Agent is worth every penny and minute i'm waiting for it

Hopefully there some sun at the weekend...


...to be continued

Wow. Considering you have 9oz of knuckle weights, your truck is light! Mine is 4lbs 4oz with blitz wheels I think i need to find some fat to trim.

[95geo]

Looks great! It looks like we have nearly identical components and mine is right around 5 lb 1 to 2.5 oz rtr with an 850 3s. I have about 80% alum fasteners but no weight savings with the FXR'S.

Keep up the good work!

Keep up the good work!

Thanks, it's still under construction.

During the waiting time for parts i give thought to a Wraith knuckle weight system:



It's inspired by YTC and would allow various weight types and positions.

It would only let me press "like" once

Thanks guys, we'll see how it performs.

I put some stuff from Germany, Finnland and USofA together and did some wheelworks:



...and mounted:



Not as light as YTC wheels, but with 6 braces/screws and 850 hubs not so bad

The weight system is under fabrication

Those wheels are pretty!! Nice job Frank!

[TSK]

For a beadlock, that's a light setup.

With those wheels on, and no knuckle weights, how heavy is your truck RTR?

[Tomy]

Looks good, Frank!

What thickness of Carbon Fiber did you use for the Beadlock discs? I would like to try this as well.

Do you have weight of the wheel without hub, tire and foam?

It's at 1850g => 4lbs.1oz. and i know, it's not in the super light weight league

I don't run light weight motors and only Axial LW gears in the rear...
...and only a few aluminum/Ti hardware.

Thanks Tomi, you made it possible 1 wheel is at 34g with aluminum hardware without hub. The discs are made of 2.4mm CF, the rings are made of 2.7mm Delrin. If you use 2mm CF for both the wheel will go down to aprox. 30g. With 2mm CF you have to take away a bit of the hubs centering ring, but only if you use button head screws.

After some testing, changing, addapting it's 95% ready to rumble

Balance point without wheels:



Balance point with wheels:



The new knuckle weights are 15mm further outside (90g each):



Cut and ground VP servo armour:



0.4mm Ti battery armour:



Made some spacers to preload the rear springs a bit:



Front end:



Back end with Egressor Ti Wraith width axles:



Rubber side down:



Front width sits at 275mm (10.83") with 725'er SLW hubs:



Back is at 265mm (10.43") with 600'er SLW hubs:



...and here is a poser shot:



I'm satisfied so far and like the way it reacts with 2080g (4lbs. 9.4oz.). As you can see, i didn't walk the super light weight way, but at this weight it's the best compromise for my driving style.

Greetings Frank

[slowride1]

how did you do the weights with the carbon plate? are you useing stock hubs or vps?

[CrawlrKing]

Love what you did with the servo armor and will probably follow your way, not too light but adapted to the driver...

[Hittman]

Super clean looking rig man. Nice work
