i started weighing stuff... so i dont forget or lose the bits of paper i write the weights on i thought id post them here.
also for those that don't have scales accurate / small enough i thought they might be useful.

IMPORTANT:
no need to say "good idea mate" or "stupid idea" or "can you weigh______" or add parts i haven't got or haven't added yet..
using different scales may provide a different weight?? who knows!?
i think the important thing is the comparison of parts not the actual weight...
so if you post results that were not done on my scales then i see them as of no use.

if you really wanna tell me something or ask something pm me please... i wanna keep the thread clean of comments so others can see the results easily.

WHAT I'M DOING:
im just gunna weigh every single part i have and post the results for people to see...

i have 4 identical scales so later after I've weighed everything i have, ill start cutting / grinding parts to see if i can make them lighter without losing too much strength... should be interesting...

my scales are accurate to 0.01 of a gram and ill be using the exact same 1 scale for each individual part so the comparison will always be the same..

well i guess here we go...

Hmm I can help with some of this. I don't have such a nice scale but hey, its at least worth something.

Let me know if you would rather I didn't and I'll delete.

Kyosho Stock driveshaft (no gears) = 1.8g

Reflex aluminum driveshaft (no gears) = 0.6g

Kyosho Stock steering arm- 0.4g

3racing aluminum steering arm = 1.1g

Stock swing shaft = .5 g each

3racing steel swing shaft = 1.4g each

plastic blue front tower cover= 1.4g

3racing front bulkhead = 2.1g

I have a whole notebook with more, I'll post later if you would like.
