I know this is me being lazy but can someone upload a setup sheet with the latest standard setup. I keep hearing using different arms and such. It would be greatly appreciated. In the mean time I will try and dig through the thread and get one filled out. I am an engineer I don't like to read just see pictures. ;-)

It doesn't make much sense since all of their other 90c packs have the 5mm bullets.

yeah, I converted my stuff to 5mm. No biggie to go back, just like all my packs to use the same bullets

I know what you mean. When I had my short course truck I used full sized packs with 5mm bullets. Was not a big deal as I just wired up a new change harness with a 5mm bullet. But it got tedious switching back and forth from 4mm harness to 5mm harness then back again.

Some tools that have I used (and still use) to learn and apply the effects of Roll Center:

http://thecartech.com/subjects/auto_...oll_Center.htm

The above link does a good job of explaining the geometry and calculation of Roll Center in very basic terms with diagrams.

Now, if you want to further that knowledge as it applies to your specific chassis, check out RC Crew Chief:

http://www.rccrewchief.wrightdesign.ca/Index.aspx

RC Crew Chief is a software tool used to model the chassis's suspension system. Once your model is in the software, you're able to make virtual changes to your suspension to see what those changes affect in terms of performance (push, loose, chassis roll sensitivity, etc.). You can see "where" the front and rear Roll Centers are. If you have a slight push, off power, you can make a virtual change in the software (change a camber link position, for example) to pre-determine the physical change you actually make on your car to overcome that push.

Another benefit includes choosing a good front to rear spring combination. In addition to Roll Center, "Ride Frequency" is another quality found in sprung suspension systems. Take the guess work out of what front springs will work well with the chosen rears. Take the guess work out of the "fine-tuning" of the springs by moving the shock mounting positions on the towers and suspension arms.

Anti Roll Bars are included in the calculations. See what changing the ARB will do before actually changing it.

Very powerful software. I've been using it on both my 1/8 Tekno eBuggy and the AE B5 with impressive results over the past 9 months. Beats the "seat of the pants" method of figuring out what changes we need to make on these complicated racing chassis's.

Feel free to PM me with any questions on the use of this software. While not overly difficult, there is a learning curve in both measuring your car (to get the information into the software) as well as knowing what you're looking for and how to go about setting your car up.

Jim

This is great! It applies to both on and off-road setups. I'm going to try and build my B5 tomorrow (no guarantees), I'll post some photos.

For the past few months I have been running the mid motor, with very mixed results. Ran my friends rear motor a few nights ago and liked it much better. Am I the only one going from mid to rear? Seems like its the other way around.

I get mixed results also. I have the conversion, so I can go back to RM fairly easily. I am giving the MM a little more time. It drives well, but my consistency when I really need it, falls short. I am still learning how to push the car and keep it from stepping out. The RM much more planted in the rear and provided more confidence. I am hoping the MM is just a learning curve.

Anyone running the brass front bulkhead? Just got mine in today, hoping it will help the car turn a little better on power.
