The main things that will give the most weight saving is the battery (a 2cell lipo in a 1-cell hardcase, weights only 156gr) and a lightweight body set (80gr).
Along with some screws from alu and also titanium, i removed the battery posts & battery holder
You also save some weight with universals with alu swing shafts.
I'm still able to loose some extra weights here and there.
For example, using the alu wheel hexes (this would give a weight saving of at least 5gr but it narrows the car a few mm's) a light weight spoiler set with the spoiler stands to be trimmed inside (this will give some extra weight, about 5gr and it looks more realistic to)
You could also add some very expensive titanium wheel outdrives (53681) to the universals and this will give (so i think) another 8gr or more of weight saving)

For now i have the electronics on one site but to have a more balanced car i should re-locate the ESC to the side of the battery.
All these things will be done before the next race, my little girl runs the car in a junior series (only silvercan motor allowed).
I've been doing this because our next races are on large outdoor tracks were speed can be a big advance
When all these things are done i will do my best to take a picture of it.

So stay tuned
