I ran my mid motor conversion for the first time on black carpet a week ago and and have a few questions.
1. Has anyone tried the long arm set with the mid motor conversion on black carpet? If so is there any benefit to use the long arms compared to the normal length arms?
2. I purchased the AUSA-C01B-XAH-MM-3 right before the C01B-X-MMA alloy chassis was released. Is there any advantage of using one over the other?

Hey Jason
I ran mine practices at the Chill last Friday and was n/p matching Brent fastest lap time ...I ran with the long arm
# 2 question the would be debatable
With the long arm the car got too much steering at the chil for my taste l.I had to turn down the epa and but it drive very smooth..
fyi you might want to run or use bodies with low front down force

i have the long arms on mine with the carbon chassis and i got it pretty well set up i posted my set up a page back, i should have my aluminum chassis by Thursday, and ill be at the track all night friday saturday and racing sunday , i should have a good set up by then lol

Hey Franko, sounds like even though the long arms gave you too much steering it was still fast. Did you try the standard length arms yet? I currently have the stardard arms on and I thought it already had too much steering. And I will be trying a Mazda speed 6 body next to see if it helps reduce the amount of steering.
Certainly this combination is interesting to try on MMCX car also.

Noticed at our state titles here one of the guys running an A800X Evo was happy with his car on the practice days (running long arms) but as it gripped up he struggled, wheras my car came improved (A800X with std alloy arms)
Any plans (can I plead here?) for some more Alloy arm length options? +1.5 std and the +8 and +9 long arms would be ideal. There are a few of us here who run just the alloy arms as they are more consistent particularly as temps increase (and we're heading into summer here).

Our observations showed the opposite - the car with long arms rolls less. Calculation of the roll center behaviour at the side roll confirms this statement.

thus oleg would you say that since it rolls less that on very low traction there could be a struggle? We are running on ultra low traction and the mmcx on the long arms suffers from over rotation at the back during mid corner on power exits. Back becomes rather snappy.

First time with the Mid-motor conversion on black CRC carpet and really liked it over the A800 with the Kaki chassis, lap times dropped about 4-5 tenths per lap and overall picked up almost 2 full laps over my previous week. We have a practice session Friday night then a club race sunday, Here is what i got so far but still tinkering with it. Made 2 small changes if they work Friday ill post them on here 
That's a lot of track time. If you get it working well with the aluminium chassis please post your setup.

"Over rotation" is just a question of the balance between the front and the rear of car. The balance of MMCX car is very sensitive for example to the presence of the most front screw in motor mount and to the mode of ST55. On low traction try the MMCX car without this front screw in motor mount and without ST55.
since you're here can i ask the main differences between the bssx and ls2 steering system on the mmcx car?

In general our linear steering systems ( LS1/LS2) suit better to the large fast outdoor tracks.
BSSX is better on the smaller tight tracks with high grip.
Both LS and BSSX can be adapted to the given intermediate track conditions via proper choice of the steering arms ( AM14LS or AM14A or AM14-3) and via shims under the inner steering balls.
AM14A /AM14-3 steering arms together with less shims under the inner steering balls increase the ackermann for LS1/LS2 and it adapts "LS car" to the smaller tracks/higher grip.

Is there going to be a C01B-X-MMA hard chassis?
