Terrible1's Wraith IFS

Bil's thinking what I'm thinking. ;-)
Sorry guys, I wish I could tell you but... A scale is something I'm yet to invest in
Well, I decided to rob my Bomber of its electronics instead of ordering something new. I've been waiting to get my hands on one of the HH Puller Pro 3500XL motors but they're not yet back in stock and it looks like I would've had to trim the rear lower link mount to fit it. not usually a big issue but, I'm not completely happy with the rear upper link angle. I still need to work out a rear sway bar and also figure out a good solution to a link riser specific to just the rear. I've got some ideas, just need some time these days to lay it out. If I can raise the link angle just a few degrees slightly greater than parallel to the ground, I'll be happy. Note the downward angle in the third pic below. Here's a few shots of the electronics and rear upper links. Super simple and clean. Oh and I need a longer sensor wire. The standard 5.5" yeah it fits but it's snug.
Anyways, I ended up having to do some "fitting" of the servo and link. What a pain in the a**! Screamer, you weren't kidding! I used aluminum servo mounts as spacers to raise the servo (for clearance), had to completely trim out the front lower link mount on the skid plate and definitely modify the servo horn (shorten). I've been working on lessening the bump steer and got it as good as I can. I haven't had the chance to get a good shakedown run yet because of the rain but hoping this weekend we'll see a dry break. Here's a top shot of turning radius:

So sick, love the first 2 pictures. Good job! "thumbsup"

If your looking for adjustable upper link mounts put in the rr10 skid. It also straightens out your trailing arms. I had the same problem on my ifs wraith i changed it out and its a win win.
Thanks guys! I finally had a chance to power this thing up and at least run it around the house. The weather has been too wet recently to get in any kind of good run. I'm pretty impressed with how she's handling (considering the lack of any sway bars). Still tons of torque twist but with some finesse in my trigger finger, it's manageable. I ended up with 16/56 gears on 3s and she boogies! The suspension is super plush but I need to fine tune the rear still. I'm getting just a tiny bit of slap between the rear axle housing and the back of the cage. I'm gonna try bumping up the shock oil weight to 50 and see how that goes. I ended up going back to the stock springs after initially thinking they were to stiff. The finished weight of the rig balanced out the stiffness. I'm hoping to get some decent video soon. I'll post it up here when I do.
I was originally considering this option when I first started this build. I wanted to see how things went first with the Wraith skid. I may still try out the Bomber skid down the road to see how it differs. Thanks for heads up!

Put some bump stops in the rear shocks. My new favorite bump stops are from the losi baja rey. That should help with the slap in the rear. If there to tall, cut a quarter or maybe in half and they should be perfect.
I'll check them out. I have the stock Axial ones already installed but they're just little guys. If I could just shorten up the rear end by maybe a few mm, I think I'd clear the rear axle. I was also thinking about modifying the rear of the cage too. It's just barely making contact!

The ones from baja rey will be perfect then since there way taller then the axial ones. And they compress too.
Sorry Screamer, I had a few runs in for test and tune but we got hit pretty hard with weather over the last couple of weeks. I've since torn the truck down though. I couldn't manage the torque twist in the rear even with the sway bar and also noticed the rear axle hitting real hard on the cage. The droop was pretty sweet on drop offs and in the air but, it sounded like a car crash when it came down! At high speeds, the truck was not manageable. It pulled so hard the whole front end would damn near turn sideways and cause the truck to pull hard to one side. So here's where I'm at:
Swapped out the rear axle housing for a Currie and changing TA's to BMRC. Swapped out the 5" Yeti rear shocks for 4" Bomber length. I'm waiting on a few things still but I already noticed a change in the rear end with just bolting up a stock AR60 to the shorter (and firmer) shock set up. I think with the added suspension travel in the rear and how soft I had it set up, I was leaving way too much opportunity for flex. I'll have an update once I have it back together and try to get some video at the same time.
Shhh... don't let my wife hear that. "thumbsup"
Alright, new update:
I finally figured out a sway bar set up that seems to be working better. I had a set of droop tabs in my spare parts that I flipped and was able to get positioned where I wanted.
The rear axle/TA's set up is just short enough now to clear the rear of the cage at full compression. I also ended up swapping out the skid for a Bomber and using DMG's trans plate to keep my Wraith set up. I didn't originally want to but, it just made sense to do so with the options for positioning the links and TA's. This build has quickly become a blend of different Axial rigs. And even though there are many similarities to my Bomber IFS, it's still a Wraith IFS in my book!
Oh and for any of you out there that have done this conversion, I ended up having to dremel a nice cut into the center plate to clear the MIP drive shaft. I'm assuming it's because I swapped out the skid and used the adapter plate for the trans. I don't recall having any rubbing issues with the wraith skid originally.
i got a very short test run in today and am super happy with the suspension now. Unfortunately, I blew out the (plastic) servo horn I had as a temp and ended my fun. I'm waiting for the metal replacement and with some luck in weather, I should be able to finally get some good run time and video. Until then she's posted up...

Both my Bomber and this rig are equally fast. I'm running the exact same gearing (16/56 with SSD high ratio trans) and power (HH PP 3500kv with MMX) to each. Here's my take though, for overall performance, my Bomber definitely performs better. I had to do so much modifying just to get this Wraith running, specifically to the steering. Which obviously affects the handling. I'm still tuned back to 60% on my end points (on an already limited steering radius) so the servo horn and end link clear the trans case. I may try finding a servo horn shorter than 20mm but in the meantime, I need a break from this project. Of course I'm running a Bomber skid for the options in link positioning which then meant if I wanted to stay with a Wraith trans I needed an adapter plate. This in turn raised the deck height of the trans just enough to cause all kinds of fitment issues up front.
For now...she runs. I'm hoping to get some time (and good weather) this weekend to do some test runs around the house of both. I'll try and get it posted when I do.
Dang then maybe I'll wait to here what you think if it was worth it to do this conversion or not.

Lol! Yeah, I know others have done the same or similar builds. It's not that it turned out bad (Once I work out the last bit of bugs it'll be one bada** IFS/TA Wraith). I think a couple of the decisions I made as far as the direction may have been what caused most of my frustration. It's a learn as you go experience. The challenge to make everything work together was exactly that, a challenge. By no means was this conversion a "plug and play." I think it was Screamer that may have said when I first started this build the steering was going to be my toughest challenge...he was right.
