those Midmotor 22's and a few others that 'must' use short packs when in that conversion

On the other side, with so many companies doing Shorties now, if AE, Losi, Ofna, Tamiya, Mugen, etc. all start building racers that can take advantage of those packs, ROAR will update this ruling....

Oh...and as someone else mentioned somewhere: "ROAR who?" 99% of people who run these trucks will never get to a ROAR sanctioned race.... Most tracks/sanctioning bodies use ROAR rules as guidelines...and since most tracks I know of don't enforce ROAR approved Lipos, and some don't even enforce hard-case lipos, I can't see many enforcing this odd rule. (Though one track did enforce the "no blue bodies" rule....wierdos...)

Mantis, I fully understand how they work and have driven cars with them and played with them. I just don't own a pair. The kinetic friction constant (Fc) is much closer to the static friction constant (Fs) so when they do slip they are still pulling almost as hard as if they were locked up. The Fc of the stock pads are a good bit lower than the Fs so when they slip you loose a good chunk of pull. If I had to roughly assign a Mu number to the stock pads and the Garodisks I'd say its something like this:
Garo Static: 0.85
Garo Kinetic: 0.70
Stock Static: 0.75
Stock Kinetic: 0.50

On that b44, did you decouple it or leave it stock?

I thought the mid-motor could use saddles?

the 22 in mid motor can run sadles. The 22 is ROAR legal no matter if you are running mid motor or rear. Just because in mid motor you can run saddle packs which is a ROAR legall pack. And in rear motor you just have to use batt foams to fill in the extra room.

I have a question ...:confused:
I am new in SC10 4x4 .. and I am having problems at the time the car landed is always tilted to the right, what causes it? for hard shock was all the same I check the front and rear. For the same shock I put 35wt oil. I also tried a battery that is lighter but still no change. Can it be caused by unbalanced weight between the right and left?

Those are 5x11.5x0.2 and the stock ones are 5x13.5x0.2...but all the wear seems to be around 8-10mm....I'm 99% sure these will work just fine as an extra shim....probably better to put the smaller one on the inside I think....

The idea is to keep a car designer from coming out with a chassis that only works with a specific size of battery pack. This rule was created in due to the increase of the “shorty” packs but it goes further since they don’t want to see a new type of LiPo pack that is so different it can’t fit into anything but this new type of chassis it was designed for.

If they can stop that from happening it will keep costs down for the racer since they can buy a standard size pack from many different companies and it will fit into their car, and it will make it easier for dealers since they don’t need to stock special size battery packs designed for only 1 type of car. This will make it less complicated for everyone involved."
