Son of a gun, it happens to be Symmetricons birthday on saturday as well, which happens to be a great excuse to get out to the track
Symmetricon thinks your truck felt darn good with all things considered, and it should feel better once the clicker is locked down, and with lighter shock oils. It is crazy how drasticly different this truck can feel depending on the tuning.
I had to +30 on the subtrim on my servo once it was assembled. I checked and rechecked, with the servo alignment tool. My endpoints are around 80L 80R, and my D/R is around 80 also. No harm no problem.

sorry if this had been asked before but I am not reading thru 625 pages at work first.
What servo's are you using?
I got to run mine the first time and was told by a couple of people that one of the t-pro high torque servos from hobbypartz would hold up in this. But with three minutes in the main I striped out the servo.
I should have known better than expect a 12 dollar off name part to work.

One page one it has a list. I use a 6030. 240 ounces. If you check page one. Lists of how stuff works in this rig is "usually" what most of us are using. 
Yeah. Spektrum is a JR spline. The Futaba would not go on by hand. I truly used a hammer and force pounded it on. If It splits or spins out, I couldn't do it by hand; roughly 50 pounds of torquing on it by hand would not budge it and was bending the whole steering setup first. So I'm happy. I forgot the ^%%#$ blue disk around the servo horn though. /BadluckCoyote
Hopefully i'll get back on the track today.
Edit: Those guys saying to limit the steering and all is well?. No. =) I'm losing 45% of my steering one way or the other. That's "wrong" and my servo at 100% doesn't bind. I'm not giving up steering. Thanks for the suggestion though.

Now ThunderbirdJunkie feels like an idiot.
He used a 6040 and knew of the similarities between the Spektrum and Savox servos...
Since he used a Futaba arm on his Savox 1258, he figured it'd be a Futaba arm on the Spektrum servo too.
Always wondered why it was so tight on there

i use Ko Propo PDS2367ICS servos.. in just about anything..
Something i tried.. was the overdrive pulley this weekend.. and seemed the belt wouldnt tighten up that well.. i run my front locked.. no clicker.. and when brake hard.. i hear something clicking.. hoping its not the front diff, or idler gears.. lol.. i am going to be inspecting it tonight or tomorrow night..
Somethings i have done, to the stock truck.. to get the truck much better.. btw.. the truck when i bought it was built but never run.. and bone stock. nothing done to it.. i raced it like that.. then did the following
32,5 front shock, 27.5 rear.. that was one big thing..
then after a night of racing.. and loosness everywhere..
10k diff, front, 5k rear.. will be going up in the front again.. 15-20k this time..
Sway bars..
rear longer camber link.. and also put 2mm shim under the inner ball stud..
also moved the rear shock, to the outer hole in the tower, and outer hole in the arm.. trying to eliminate the roll of the truck.. may go back in on the tower some..
The truck feels great.. now.. something i been noticing..
I race Kyosho everything else.. and usually got things setup to be driven.. not thrown around the track..
with this truck.. it seemed, the harder i drove it.. the more it worked.. now.. me being tenative.. i didnt really like doing that.. i dont do much testing.. my testing.. is my qualis.. lol.. i just show up.. race.. try different things..
Everything i have done.. has had a positive effect..
Next week.. i should have the clutch basket on the truck.. with thicker front diff.. think i will go to the yellow spring in the rear to eliminate so much weight transfer.. got blues all the way around right now..
i want to try to get the truck to quit rolling so hard in the corners..

Thanks, guess I need to take a little time and look though all of this

Welp, normal Sunday All day at the track day.
No losi's today. 2 slashes, 1 ofna, and 1 other sc104x4.
We tore them up. Him and I were down right fast. He had the same track line in mind that I did so it was fender to fender awesome runs. He had a camera on his rig through some of it so i'm really hoping it gets on here and posts it like I asked. If you read this, Great driving!
I tore up another Idler gear today, and replaced it on the bench in 20minutes. My slipper is 1mm from flush, with stock pads and I stripped it. Which worries me. But I have 4 more. For 5 hours of fun. It was worth a fix.
This truck. I'll be a broken record: Kicks so much more butt now. I am a proud AE driver once again. The guys pulled off the track and just watched us battle it out and enjoyed every minute of it. Looking forward to tons more. My batteries are starting to go. Venoms that are a year old now and ran hard. They're starting to get warm and my motor temps are going up. (not a pinned mod difference, Already tested and taken into account. This is after that)
So it looks like i'll be eating my words about those damn Gen ace batteries and trying a handful. I'll use my T/P Batteries for race only.
Putting it on the table and tearing down a little bit and going over everything.
Edit: as far as the emulsion: I noticed it hates big bumps, but breezes the little ones. Being sideways and hitting a bump doesn't flip me as much. (sways, placement's same) So I'm happy with that. I don't like hearing it bottom out just on two sections but I can live with it. Lesser Evil.

The vids are not as epic. It is really bumpy and I was getting seasick while watching it. I did find that the footage my son had with the camera on the top of his truck was much better. I will wade through all of the video to pull out the highlights though. The most clear parts were the slow movement footage like pushing over flipped trucks.
If no rain I will be back out this Sunday.
Hope the mystery skipping doesn't come back.

Tried drilling through the shaft for the pin mod and broke the bit. I will have to go to my in laws to use his drill press. I did however charged up some packs to test some more changes I made and noticed something that I heard before but never paid attention to it until now. The first pass with the throttle the truck has power, then all the sudden it's gone. It still drives but it sounds like it's slipping. I did what Craig suggested by marking the slipper/plate with a marker because I lock mine down. Sure enough it slips like a mug. The power is gone and the motor heats up quick. I have locked it down to the point where I could snap the shaft. I am using the ht pads as well. What can I do for now to fix this. Take the spring out and fill it up with spacers or drill though the plates and bolt them together. This sucks big time. Anyone have any ideas.

EDIT: Checked temp on the slipper plate after 5 minutes of cool down and it was still over 140*F
