I have never been a big fan of the stock TTR S3 wing mount. This was mostly because I didnt like the look of it, put the wing almost directly on top of the rear shock tower. I also found the stock TTR wing mount to be very soft, which isnt always a bad thing, it will absorb impact better if its soft. But I did not like how all of that force was held only by 2 3mm bolts to the back of the tower. These bolts were always bent, or the screw holes on the bulkhead were getting stripped out.

I decided to try to modify a Jammin X1-CR wing mount onto my TTR buggy. Well it bolts up almost perfectly.
The first thing I did was to drill out my rear shock tower to accept the 4mm bolts for the jammin, I had to do this to both the upper and lower shock tower mounting holes. I also drilled the bulkhead mount holes so they would allow me to thread in the 4mm bolts and still allow them to tightn up.
Next I needed to trim down the upper mounting tab on the bulkhead, as the Jammin wing stays that pass through the tower have more material in the contact area. (see photos) I made the cut out big enough to allow me to use 4mm lock nuts on the inside of the tower.
I also need to use some thick plastic shims which come with basically every Jammin car, but never get used. (I think they were hub spacers for the old 9.5car)
I then mounted up my Kingz Head aluminum bulkhead brace and marked holes so I could drill a new cross bolt hole. I picked up a 3mm x 50mm bolt and again used the same type of shims as earlier and bolted it all up.
I did trim the wing stays down (the part that passes through the tower),but may not be nedded.
This wing mount feels much more stable, and with the 4mm bolts holding the wing on, I think I shouldnt have any more bent bolts.
I doubt many people will care about this mod, but if you do have questions, ask.

Thank's outtafocus, Those same quirk's with the wing have bein bugging me.
The stripped wing angle has the frt end lifting Not! when ya want
and makes learning to fly a bit more of a brake dance
than I care to pancake anymore.
I'll bet the stiffer thicker wing stays and bigger 4x50 will help with bending Ctr brace bolt.
My Ctr brace is tight[@1mm off] to the right and would like to try the TTR Alum' bulkhead bracket
but it also leaves several mm of 3x50
unsupported bolt=bending length.
You'r Post & Pic's are are above and beyond!! This is my first 1/8 scale
out of 10 rc models and am realy looking forward to putting down this
long car and a tunnell. Then I'll need want to practice, Eh!?

Straydog, as long as the weather stays nice and your track remains runable, I will be up in Edmonton for your leg of the CORCS series.
I will have this buggy with me, so feel free to come on over and chech it all out, you can see how I modded the bulkhead better in person.
By that time I should have at least one club race on the new wing mount, I will be be able to talk about durability a little too.

Anyone run one of these on your Thunder Tiger?



I'd like to get some measurements from you if you run this. I'm thinking of trying it out on a different rig.

Overall length of the posts
Length from bottom of threaded post to ackerman arm mount
Length from top of ackerman arm mount to top
Length from top to servo saver bellcrank
Lenght of ackerman mounting arms

Thanks!

Dont bother trying out that aluminum servo saver. Unless you want to use half of a plastic servo saver also.
The problem is that the aluminum galls together. (seizes)

I think the next project for this car is to find a better quality rear chassis brace.
I feel the threaded torque rod is rather a poor choice. With even olny a small amount of wear on the plastic rod ends, my chassis flexs way to much.

Any ideas yet??????
I have access to more Jammin stuff so I may try one of those braces.
Guess its time to start scoping out other cars in the pits.

Yah I was thinking the same!?! , again . Last Yr I was watching my flat chassis,Could be Titan, need another. I bought used as part of an ex TTR Team kit, The Ctr Rr brace realy likes to loosen the bottom screw and the cut/modded plastic wing brace at the top dosen't support enuff bolt. That Alum TTR brace is Beautifull! and set's a whole new angle to it, @ 10' left? Mine's dead straight. And interfiers with the radio box, especialy when the screw's have pulled out of it! and the load is on the Right of the wing brace.
All the style I've seen since x-ray's seem to be solid, plastic and alum' probably a way older idea although. Even seem's the Truggy's are using solid braces and tunning the yield or bending moment with size and matterial of the structure...bla bla bla I Like the Idea! Now what who's is going to take the least ??!!! to work? All the BEAM type I've seem are designed to plant both end's, locked to case & housing some 4! screws!!
I'm thinking that outafoucus Wing Mod a TTR Alum' bracket and some Post of a brace with at least 4mm btn & top may help.
But...when my Pit Man is a couple sec Faster than ME I'd better go practice for our Mothball Race#1 Sat, maybe Club #2 Sun! Or Team Straydog will be pitting his own car!!!

On the chassis braces, leave the ball end ones in. If they have a lot of slop put new plastic ends on but the flex is the whole point of the flat chassis. If you put beefy, slop free braces in it then you might as well go back to the extruded chassis (that worked great, remember ). Most of the top Mugen drivers scrap the CNC braces in favor of the ball end ones. The flex makes the car work better.

A Mugen fuel tank works in a TTR S3 I think. Check it out to be sure but the Mugen tanks are great.

My fuel take just decided to stop sealing when you close the lid.
Im popping in a Mugen tank so I can run this weekend.

With my tank crapping out, I didnt have a chance to given the jammin wing mount a good testing.
