Cant wait to see you start this...Im glad more of you guys are doing Axial based MTs, I want to start another one soon too.

Great parts list too, I want to upgrade to the Vanquish products myself

[Rootar]

plotted out my chassis design



got my tires and wheels on the scale this one already has an slw hub installed

these are pigs!



Looks like im going to be able to flip my servo horn and hide the drag link and straighten things up.


Full size templates are always nice

[Ballistic17]

That is one killer build you have going. Can't wait to see it finished.

[mmatthews]

Looking forward to this build. Like seeing the use of the template. I'm a drafter by trade. If you ever want to draw one in Auto Cad hit me up, my office is down town.

[Kingclod27]

Damn.....looking good aleady.. I like how you have the servo setup. Ive only seen that on a few Wraith setups, I have Junfac carbon steel driveshafts that will go on the Bigfoot and the next Wraith tuber im doin.

wheelie bar - wheelie bar - wheelie bar!

Looking good so far. You sticking that axle/tire width or going with a different offset?

Dinky RC makes a similar design too.

looking good so far rossipoo..


i think im gonna shoot for 14in wb & 16in track width on mine.

should be ordering parts next week for my project.

still cant decide on a body just yet..


cant wait to get'em all side by side!!

[Rootar]

think 15.25" wide is as wide as ill go, i dont want the extra stress on components of going wider and i dont want a bunch of scrub in the steering either.

The frame will have a rear crash/wheelie bar just like a fullsize monster truck. It will also have a HR wraith swaybar setup.

[Rootar]

here is more of the frame i work on for a few minutes this morning

[701 Technique]

I have a pair of wraith axles laying around that I was thinking of doing the same thing with. Chassis looks great so far, looking forward to some progress

[tedo]

Awesome! Those tires are super hefty and awesome looking. Can't wait to see more.

[Rootar]

I pulled these axles out of my 2.2 bronco and honestly I'm not sure how much faith I have with them and the monster truck because 3 out of 4 universals were bent all to hell. And the little 2 gear axial diffs look pretty weak like a revo and are not that tunable since the 2 gear setup doesn't respond well to fluid changes (or should I say doesn't respond at all). They are also not sealed but you can put enough fluid in there to keep the gears lubed.

We shall see how they hold up but I don't expect them to be bullet proof by any means.

[Rootar]

a little more progress today

this is how you make sure you have matching sides,




and then you un bolt them and finish welding both



test fitting the skid and tranny



and here is the electronics layout

battery will go right above the tranny and everything else just above the front upper links where the rx8 is in the picture.



tomorrow ill get the upper link mounts done and get it ready for shock and body mounts.

[ROLANDROCKSHOP]

wth??

i thought you said this was going quick and easy..???



you should be out "Gooning" in your yard with it..

[Rootar]

I haven't taken much time to work on it only 30 minutes or an hour here and there.

[Rootar]

upper links mounts in



crossbrace as low as possible for battery mount (plate will go under the tube)



good view of link geometry and nice high upper links like a monster truck needs.



mocked up, ride height will be a hair lower and the body will be lower and cut aswell.



top view looking at links and drive shaft.



the axles are clocked a little with my servo plates and it gives a nice smooth drive shaft angle.



new lower steering setup and yes the horn will be down and the tierod will go under the drag link, it is inline line with the center of the axle tube.

[Szczerba]

Yes sir.

[ROLANDROCKSHOP]

getn there...

link geo-metery looks right on..


my parts should start arriving friday or saturday for my mt build..
