For the guys useing the RS PRO esc with 540 motors, what are your temps on the esc looking like? Also how many lights are you getting after a qualifier or main? I you have any ESC set-ups to try please post them, so I can give them a try.
I have the following:
RS PRO ESC
LRP 6.5 with 13mm rotor
14/62 (got a 15 to try next)
No timeing on the ESC
-5 timeing on the motor
Reedy 60c 5200 saddle pack
This set-up is so much better than my 4.5 Tekin 550. I had been running 15/93 48 pitch, but had a spur strip out on me so I went with the 14/62 32 pitch. The motor seems to be doing find temping at 140-145, but my esc actually hit thremal the other night during the race, once I switched my gearing to the 14/62 32 pitch. Would going up one tooth to a 15 pinion make that big of a difference? I see Ty Tessman ran 15/62 with the same motor I'm useing, but he used a LRP TC Spec V2 esc. Is the LRP esc more suitable for this since it has a fan? I've always used a RX8 with 4.5 550 in the Corr trucks I've raced, so this is my first go with 1/10th stuff. I just don't want to have to put my RX8 back in with this motor. I'm a pretty smooth driver, so I really love the 540 set-up.. I have all the power I want, without getting the truck all sideways with the big 550 motor.
PS. I run on a 1/8th scale style track that was super tacky Saturday from the rain we a had gotten earlier that day.

I've been wanting to see how much smoother a 540 would be but don't have a motor to put in and well... I'm lazy.Why don't you want to put the RX8 back in?

Im looking to get a little more on power steering in my truck .
This is a video of our track. I am driving the Black and Yellow Sunoco truck...

I'd really like to get my hands on your remote. I'm planning to go to your track next weekend so maybe then you can let me bash it for a lap or two. I've been wanting to see how much smoother a 540 would be but don't have a motor to put in and well... I'm lazy.

I'll let you wheel it so we can compare the difference.... I can tell ya this, if your anything like me, you will be buying a 540 after you drive it

Look at Roar Nationals this past weekend. Out of the top A-Main guys running....half of them were Losi SCTE's, including the champion. There was only 1 AE truck that made the final 10 in the A-Main compared to like, 1/2 the field which were Losi SCTEs. The "Top AE Drivers" (ie. Ryan's) didn't even run in the 4WD Pro 4 class. On a year where you can make a name for your newest, ground-up design? Sure, all of them are the worlds best drivers, but all things being equal.....even in the hands of Top Pros, the Losi is faster. Hell, the SC10 4x4s that did run at Nationals all had Saddle Pack Configurations in their cars. That should tell you a little bit that the AE truck is just well, not as balanced and not where it should be cmpared to the rest of the field.

And that was based on Travis Brock's set up.

Lastly, coming from an on-road background, I am EXTREMELY smooth. The problem with the truck is that it is stressful to drive it fast around the track. You have to wait to be pointing in a straight line to be able to accelerate well without the truck doing something weird. This is not how a 4WD should be driven, and this is where the advantage lies over a 2WD truck. A 4WD vehicle should be able to start accelerating sideways, and smoothly transition over to a straight line. With a light weight SC104X4, this is extremely difficult to do aggressively and this translates into lost time on the time sheets. Adding weight made this better. This is not an issue of it being AE or Losi or Durango. It is a stability issue, which can very easily be mitigated.
Oh, and yes, our track is big, very big. I did state this on previous posts, but I have a feeling you either did not read them, or simply you read what you wanted to read once again.

Only thing is I noticed in your pictures that the weight was placed on each side of a centrally mounted battery...at least if I'm seeing that right...I wonder where I'd put it in a stock layout and still have it be balanced.

2.You do not have to "wait to add power" with extra weight. As a matter of fact, adding extra weight allows the truck to accelerate better as there is more pressure being put on the tires. I'll put a simple and extreme example for you: try accelerating hard with a pick up truck and an empty bed liner. The truck will peel out all the way to Monday. Now add some weight to it. Up to a point it will accelerate quicker because it can generate traction. At a certain point though, the extra weight will make it sluggish. This point was found on the SC10 4X4 by adding weight slowly and looking at lap times. Once lap times stopped getting faster (and in one heat actually were 1 second slower) I took away weight. With this process I reached an optimum weight for the truck. This is a bit of the experimental method being put into action.
3.Weight adds stability, it does not take it away. This one is easy and I'll let you answer it: what's more stable, a Losi or an AE SC Truck? ....

I think from tunning standpoint you want to start with a lighter car and like you said find that perfect balance gradually (thus the comments of sc10 being more tunnable). Losi is easier to drive out of the box, why? cause that point has been reached or very close to (i.e. adding more weight will only make it sluggish) . Bottomline, its easier to add weight than having to remove it..

what if he wants a more planted and easier to drive 4WD SC instead of fighting the truck he has? The AE truck is just not well-balanced, and box stock, it just plain F'ing sucks. No ifs, ands, or buts about it. You need to go through a few tuning revisions to "get it right"...and even then, it is probably not completely there. For anyone who says you need to drive it smooth, etc....well, you should be able to push your truck when you need to. Not TipToe around the track hoping your SC10 doesn't get squirrely or traction roll it around a sweeper/turn. Bottom line is.....overall, the AE truck is just not as good as the Losi.

I would imagine if I swapped rigs w/ the local Losi's guy's I'd probably still beat them.

chassis brace
I know a few guys have made a few different chassis braces and a few have noted the improvements they have made ( belt tension for one ) but have there been any negative effects ? parts failures etc ? I have made one out of a titanium stem bolt from my 1990 klein mtb ( crude but light ! ) but am a little apprehensive to bolt it up until I see more feedback...
I am using the front overtray mount and the front centre brace bolt hole.
cheers.
