First depending on the battery, there is only a negligible difference in weight between a short or standard battery of the same capacity: a standard ThunderPower 3800 pack came in at 240.1g while a short ProTek 3800 pack came in at 239.8g (according to my $30 digital scale).
I only ever ran my F103 once, and I experimented with both the short and standard packs, and found that the standard pack was easier to drive, though less responsive, not due to the weight, but most likely to the weight distributed over a wider area and needing that fraction of a second longer to overcome the inertia of a mass placed farther from the center-line of the chassis.
FYI, I was running just a stock F103 RS with Tamiya Type A tires, which still worked great after being in the box for 10 years! Wish they still made this compound as I was keeping up well with the Shimizu shod cars that day without having to use traction compound.
Would like it if there was a "historical" F1 class to run cars out of spec from the current adopted standard of 190mm and rubber tires--any F1 chassis/tire/motor combo.
