Which is lighter ? 1 black or 2 nifties ?

Usually whenever someone uses 2 nifties they're told to switch to a black because it's 2 kgs (30 kg) lighter than 2 nifties (16 x 2 = 32 kg). But is it though ? To test this, I made 2 chassises, one that's completely airtight for the black and one that has 1 pixel of wiggle room for the 2 nifties (so that I can stack them). However, upon checking them both :






Looks like 2 nifties are in fact lighter than 1 black.... by just a kilo. So what does this mean ? It means that if your bot can afford to be at least 3 clicks tall then use 2 nifties to substitute a black as it's lighter (don't try to substitute 2 blacks for 4 nifties though, they'll end up heavier). But, if your bot can't afford to be taller than 3 clicks then go for a black.

Interesting findings.
However it doesn't really prove much as in a larger bot that would require more batteries the surface area calculations are a lot more complicated.
You'll need to look at which battery option allows for a lower surface area combined with other components in a chassis.

few issues-

the control board is larger than the nifty, so it should be used as the baseplate

once the chassis becomes larger to fit more components, those extra height clicks are exacerbated (the bigger the chassis, the more weight will be taken up by the extra height)

IIRC the control board is 1 pixel bigger than the nifty so it should still fit into the test chassis since it has 1 pixel of wiggle room.

But yeah, I'll get around to testing practical applications sometime soon, been pretty busy lately.

Interesting test, actually. I would definitely like to see it with a control board.

Alright, so I re-did the test on the 1 SnapperII + battery setup that every MW HS uses, and :




They're pretty much equal.

the chassis that has the black can be lowered even more

no it can't i've tried it

[09090901]

whatever you say bro

fyi at the lowest height for a black, only the black part of the cb should stick out

Welp turns out it does work :
