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...)
I thought the mid-motor could use saddles?

On one side of the argument, the rule states that you just have to be able to fit a regular roar approved stick or saddle pack, so if you build the truck so that it will fit either of those, and then use foam to pad it for the shorty, then you are still ROAR legal.

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?
Garo Static: 0.85
Garo Kinetic: 0.70

Anyone tried these washers/shims for the Diff outdrives (under the sungear)?

can you fit a full size pack in the car in the rear motor configuration?

Unbalance or....
I have a question ...
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?

It should work as an additional shim on each side.
Inside meaning - Sungear side or diff housing side?

That's not the point.
" Steve Pond who is the current ROAR president and did confirm the 22 is still race legal and he also confirmed that saddle packs are ok too.
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."
