I have a different take. I do love the shorty but could never decide which position to put it. Rear = awesome fwd bite ok ok jumping, front ok fwd bite great jumper great in corners.

So I bought the ip 3800 stick full pack, it weighs less than my shorty and spreads weight accross the chassis .

Or you could run the shorty right smack in the middle of where a full sized pack normally sits to keep your F/R balance the same.

yes and you can also move it forward or back if you feel you need to .

Yep, I just love the ip battery for punch compared to the protek 70C shorty which tapered off in 6 months.

On another note, has anyone tried running saddle packs one all the way near servo and the other all the way to back? In theory more weight on/near axles should help weight transfer correct? Mostly for low mid grip tracks. I will have to rewire my esc for that but will do it sometime next week.

I prefer running my shorty in the forward position and have flipped the rear battery holder around. No longer need to use foam spacers as it fits perfectly and is snug. If I ever needed to move it back, I just flip the brace around. If I want to run full size lipo, I remove the brace all together... R'Dub

Have you considered moving your transponder to the opposite side of the car of the reciever? Then you could reduce that weight used for lateral balance.
Just a suggestion.

I have my setup something like that, but the forward battery holder is all the way up against the servo and I have a piece of foam in front of the rear battery holder to take up the extra space.

Yes, it is. What I'm suggesting is that he move it to the left side of the chassis where he has some balast placed. I assume the balast is for lateral balance. If he moved the transponder there, he could reduce or remove the balast.
A minor detail for sure

I have never heard of IP batteries. Can someone send me a link. I have larger stick packs (orion 90c 65000MAH) and I'm looking to get a shorty pack for my RB6 and wanted to see if anyone had any recommendations.

Why would you mount a transponder back on the side...? It should always be in the front.

I appreciate the suggestion, thank you

I prefer the cleaner look and the car is balanced for my likinig. If I did run the PT on the other side, I would need either an extension (to run the wire around the cradle to the RX or to run the wires over or under the battery... Not fond of either route and I like having the PT closer to the front of my buggy.

Thanks again for the input!
