[Old_School_RC_1]

Been working on this one for a while on and off...I'll spare all the details on how it came to be and let the pics do the talking. Will update it going forward.

Specs:
650 Brushed
Tamiya semi tranny
Axial Dig Wraith tranny flipped and lockout removed (2/4wd)
WK rear axle
Hybrid Redcat/HPI/Tamiya front end
Custom 6061 chassis

Progress so far:
Start....always plan!


Laying it out


General progress shots




Approx. Stance


Most recent work - cut and detailed the chassis plates


Have started disassembling and finishing/painting the chassis parts. Most were just roughed out, and now "final assembly" is taking place. I'll post up some more progress pics as I go along

cool
just when i thought scratch build projects were ancient myths. you come along and prove me wrong. kudos to you good sir

[Old_School_RC_1]

Nah, scratch builds are alive and well. Check out some of the crawler-scaler forums. Some great stuff going on over there.

Some of my others...should remember some of these. Some old, some new.











How about a scratch built T-case? Not paying $60 for one. Made this for <$20...tucked into the Jeep chassis above

Been distracted with a few rally builds, a hurricane, new job, wrecked Xterra, but things have finally calmed down and have gotten back to work!

Got the chassis and assorted parts trimmed up and painted finally (metallic black just for something different) - didn't spend a ton of time with the files on this getting the cuts perfect, but it's all straight and square - good enough! Started reassembly. Doesn't look much different, but spent a ton of time shimming, spacing, and getting everything working smooth since most of it was just mocked up before.

Overall chassis progress:


Rear...specs:
Axial 14/36 HD gearset, stock WK axles
RC4WD straight axle adapters
Converted to 4 link ilo 3 link
El-cheapo shocks that actually feel butter smooth...and more importantly were the perfect length
Wraith swaybar set...the swaybar is sheathed in brass tubing that runs though the chassis, lubed and sealed. No play, and nice and smooth.
Stripped and polished off all the ano everywhere that wasn't blue.


Front..specs:
Axial HD gears to match the rear
Redcat steering converted over to bearings (that I'm pretty sure will be the first part to fail) shock tower and gearbox housing
Modified Tamiya Wild Dagger arms to get the right width for the body
Duratrax Maximum C's and spindles
Mystery parts box dogbones.

Almost done, just needs an upper plate to tie the steering posts to the gear housing - the stock Redcat piece worked fine with the built in camber of the stock chassis, but here it's all flat so I need to fab a slightly longer one. Thought I was done cutting metal - missed that apparently.

Took forever to get it all sorted out with no bump-steer or weird camber angles, but now it's got good travel and geometry overall. Now that it's sorted out, just need to go back and sleeve the links for strength.

Sweet! I'm watching now.

Thanks man - have patience...this one's a slow go.

So, got the front buttoned up. Using the existing plate as a template, I cut a slightly longer one and hollowed it out so I could access the set-screw for the shaft. Did a quickie job on it, but since it's buried in the chassis, no one will notice but me.


Front pretty much bolted up. Shocks are an ancient set of PL shocks I stole off my .15 Tmaxx. Super stiff, not sure if they are going to work. Have to wait till i get some weight on them and see where they are at. (would work great on my 1/6 Dodge though)


View from the top! Looks oddly bent in the pic for some reason, but it's as straight as a carbon arrow. Couple more specs:
All RR steel gears in the Axial tranny
Modified Axial dig (no axle lock) - just 2 and 4WD
Front shaft is a bunch of Wraith Shafts JB welded together. Rear has some JB weld in the extension, and the female part that is exposed is reinforced internally with an aluminum tube and some more JB weld. Have no idea if they are going to hold up, but they are pretty darn solid.


Finally, since it's now standing on its own, figured I'd bolt the wheels on and see what it looks like. Ride height is more or less where it'll sit when done. Me likey!

[Lille Buller]

That thing looks so awesome!

[Old_School_RC_1]

Thanks mate!

Got the tranny and steering servo mounted up.


Though the design is similar to my Dodge build, this one has a much lower COG..motor is about as low as I could get it, and mounted further back in the chassis. Since the Raptor will be geared for higher speeds, should help a ton.

Raptor chassis:


Radio and battery tray. Needs a ton of work yet. Going to trim it up, paint to match and need to mount a servo on the bottom somewhere for the dig

[Old_School_RC_1]

The test run..number 1. Note the lack of a servo for the dig, sorta popped itself off. Exactly why you test run.


Tweak time. "Dig" servo...fabbed a new bracket to hang off the radio tray, the one mounted to the chassis didn't work out.


3 speed shift servo...tried a linear servo here, but didn't have the torque to ram it into low gear.


Body mounted...standard clips in back, and velcro in front. Experimenting with wheels and tires here. Think a more rounded profile looks better than the square Flat Irons. Not sure yet...been trying out a few options. Started pulling parts off for bodywork too.


Sitting a little lower than I thought, WB needs a tuck in the back

Holy heck man, wish i had the confidence to start hacking away at stuff to make such awesome rigs..!
