Another question regarding the suspension arm inserts- For the front, does it follow the same chart as the rear? Looks like could be used to adjust track width as well?

Does anyone have a good base setup for a loose, rough outdoor track?

Yes it applies to the front also, each step adjusts track width.

My kit comes tomorrow, any tips before I start the build that might be noted for this particular kit? My MP9e went together flawlessly.

Put both cup joint sponge pads up front. One on the slipper assembly and the other on the drive gear shaft.

Why would you suggest this? Is the front center dogbone too loose or is it just because the car is more quiet then?

Thanks for the help. I'll give that a try.

Question: Since CC IN and CC OUT both equal a "0", what would be the difference? Another words, both fronts holders with C IN or both with C OUT? Thanks...

The track width would be narrower/wider, yet still have 0 degrees of sweep.

What's your shock setup? Seems like with rear motor configuration the rear end of the car just slaps like crazy I went to 4 different piston and oil setup with no luck however the buggy is on rails but it just bottoms out no matter what shock setup I did.

Small indoor track? 18t

Big out door track? 20t

With the orion vst2 6.5t no timing or boost no temp issues and plenty fast

Finished my ZX6. Just need to cut out a fresh wing and set the camber, toe, ride height etc.



There is only one problem... I was aiming for 1613 grams and overachieved apparently. Total weight is 1564 grams. Looks like I didn't need to buy the SMC 3500mAh packs and modify the battery posts! Not sure whether I'll just put in the SMC 4600 batteries (about 60g heavier) or add some brass/copper weights.
