Which gets me 4 deg toe and which way is 2 deg toe. Nothing in the manual about it, nor durangos site.

standard way round for the hubs is the lug for the wheel scrapers towards the back (according to manual), so I believe:

for 4 degrees : run 1deg hubs with lug towards back
for 2 degrees : run 1deg hubs with lug towards front

Not put it on setup station to confirm yet though...

Ran into another few snags with the build...the first is there are several spots where a screw goes through a plastic part then threads into an aluminum part...however they didn't mold the holes big enough for the screw to just slide through so you can cross thread the aluminum if you are not careful or aware of this. I had to clean up one hole with a 3mm tap a bit and was fine...after that I made sure to drill out the plastic so the screws can slide through them and thread into the aluminum.

Also the instructions have great pictures but need some text clarification in a couple places and in others need to change the order of assembly. Most notably in the radio tray assembly as you have to take apart some of the car you had already assembled in previous steps to put the tray in.

lastly is...the 2100mah LiFe pack I bought doesn't fit in the battery box What batteries will fit? Has anyone cut away that part of the battery box and just taped in a bigger battery?

Here's some more info on roll center and roll axis. It's all the same info just different methods of coming to the same answer, doesn't matter if it's a Corvette or a RC car, they all have axis and planes the suspension geometry works on.

I ran this whole weekend with the Fisher setup, made some changes from what I ran at PNB and they were very good. I will try to post some more info later on.

Not that any of that really matters, the point is, how does the car feel different on the track, not, what is the theory behind it.

The protek stick lipo packs work. I have never ran a life battery. But any Mugen style pack will work too.

Thanks for the battery suggestions guys! I went back and looked at the pics on Durango's site and one of them has the battery in the car without the plastic box...right now I'm considering running my car that way. remove the plastic box assembly and just mount the reciever on top of the servo and the battery to the radio tray. I'll have to ponder that a bit before making my decision.

I have a spot on my battery box that is melted from the header. IDK if I would run it without a box or defiantly use support hanger.

I did the tank insert mod on my own Saturday evening after returning from the track. Tonight I went one further and used a ball end Dremel bit to cut a groove in the outside of the insert and the inside of the tank opening. I then placed a 3/32 or so thick o-ring in the groove on the insert with a bit of grease on the o-ring and slid it into the tank opening. This locked the insert in and also makes a completely clean fill with the gun.The 1st one I did worked ok but if you didn't know the Losi gun will fill faster with the gun fill lid propped open,this 1st mod worked great without the lid propped open but with no o-ring I it would still shoot fuel out the top around the insert and tank opening with the gun lid propped open. I use the fuel bottle cap to hold the lid open. With the 2nd mod with the o-ring I can fill the tank with the gun lid propped open and not loose a drop of fuel.
Sorry I dont have a camera to post some pics but it is not much different than what Tix did except I added an o-ring.
With Derek's Driving style he is usually making one extra stop in the longer mains and anything we can do to save time in the pits really means a lot.

After driving many new buggies the past few weeks I have decided to run Durango. This past weekend I drove one and I have to say it was amazing. With setup help from the team guys I cant wait to run some races with this car. For some reason my confidence with this car really has me excited about its potential. Great Job Durango!

That's a great idea with the o-ring. I was going to try an orange but I wanted to run it first. I cut mine pretty tight so I didn't get any leaking but the o-ring is a great idea. I'll have to do that tonight
