So I could easily use on of my Reedy shorty packs in 7.6V 4000mah from my TLR as I have the correct adapter from bullets to the T plug on the 1060.......with a block of foam and drop the weight and push it back towards the middle of the car vs. the heavy front left wheel I have now.

Of course I am guessing for TCS I would have to use the full sized pack for a stock(ish) class, right?

EDIT: I put one of my shorty 4000mah batteries in with the proper leads and a small block of foam to keep the batteries weight out back for now and it came in at 1392 grams with the body......so about a 50 gram reduction. The car alone with no body or battery is ~1059 grams as is.
