Weight Specs - Stock vs. Modded

i seen a while back someone asked how much weight that you actually saved with a cheese grader chassis vs. a stock chassis. i figured i would get a weight thread started to show what some of those differences were. all weights will be displayed in grams using a digital gram scale. i will include a photo of each part being weighed and do my best to explain the modded parts in detail so you will have as much info on the part as possible.

let us start with the main chassis first. this chassis is a b-stamp chassis. it did not have the 2 small holes for the inline battery. these 2 holes were drilled and countersunk into this chassis before the weight was taken. sorry but this was done before i got the idea to weigh everything, but seeing how small those two holes are i feel it will much less than 1/2 a gram difference so it shouldn't affect the weight enough to really matter. this chassis weighed in at 168 grams.

next we have a modded b-stamp chassis. this chassis also has the centered battery cup holes. the chassis has had the sides cut down to 1/2". there are 30 half inch holes drilled in it. and the rear of the chassis has been narrowed for the rpm worlds arm conversion kit. and i don't want to leave out that this chassis ha an excessive amount of wear under its tail due to bottoming out on the street or where ever it was drove. this chassis weighed in at 124 grams.

so there we have it. there is a 44 gram difference in weight between the modded and stock chassis.

more weights will be posted soon.

That's more than I would have guessed. Not too significant with today's batteries and motors, but back in the day that could equal a few extra seconds of precious run time.

now we have the motor plates.

as before i will do the stock on first. it weighed in at 24 grams.

here is the modded one. i could have lightened this one a little more but i felt this was enough. it weighed in at 20 grams.
DSC01673 (Small).JPG
well it wasn't much of a change but aprox 16% lighter is a decent change. just think.. if you are one that likes to work on balancing you car out with weights then this is 4 grams you can place elsewhere.

now this one is a little different. this post will show the weights of a stock buggy nose plate, a stock truck nose plate, and a lightened truck nose plate.

lets get started with the stock buggy nose plate. it weighed in at 38 grams.

next up we have the stock truck nose plate. it weighed in at 29 grams.
DSC01669 (Small).JPG
ok no since the nose plate will be used on a buggy i had no need for the truck mounting holes. so i trimmed 1cm off the back edges. i felt this would save enough weight with all the other hack and slashing done to this chassis. it weighed in at 26 grams.

both chassis sets are currently at the powder coaters. i will weigh them again to show how much weight the powder coat job will add. but since powder can be sprayed on in different thicknesses these weights will only give a vague idea of what your chassis could weigh. as time passes i will post more weights of other parts.

Now you just need a cut down buggy nose piece to compare too!

It doesn't look like those Dynotech arms take dye very well, how long did you have them in the dye?

i left them in a good while.. the fronts did better than the backs.. the edges of the backs turned floru red very quick but didn't take on the non cut sides much at all. they would do black with no problem but colors are a waste of time to do.

if i ever get a precut nose plate i wont mind hacking it. i don't wanna thrash a decent one though.

I just bought a new digital scale and hope it's cool if I add some weights for comparison. Even though my scale is different, I think the numbers will be close.

Andy's black wide track front arms: 8 grams

AE old-style shorty front arms dyed black: 8 grams

Andy's black rear arms: 11 grams

Powder coated part weights. now take in account the weight added by the powder coat will very depending on the thickness of the coating. this post is just to give a rough estimate of the added weight to better inform you aprox how much weight it will add. these pieces in this post are also the exact same ones weighed above.

gold b-stamp chassis in first post. before powder coat it weighed in at 168 grams. it now weighs in at 185 grams. 17 grams added with the powder coat.

next up we have the gold buggy nose plate seen in the 4th post. before powder coat it weighed in at 38 grams. it now weighs in at 42 grams. 4 grams added with the powder coat.
DSC01800 (Small).JPG
now on to the gold motor plate seen in post 3. before powder coat it weighed in at 24 grams. it now weighs in at 25 grams. 1 gram added with the powder coat.
DSC01802 (Small).JPG
ok now lets move into the modded cheese grader chassis set.

here is the black drilled, cut, and hacked chassis in first post. before powder coat it weighed in at 124 grams. it now weighs in at 133 grams. 9 grams added with the powder coat.
DSC01805 (Small).JPG
next up we have the black truck nose plate that was trimmed down seen in the 4th post. before powder coat it weighed in at 26 grams. it now weighs in at 27 grams. 1 gram added with the powder coat.
DSC01803 (Small).JPG
and lastly we have the black motor plate that was cut down seen in post 3. before powder coat it weighed in at 20 grams. it now weighs in at 22 grams. 2 grams added with the powder coat.
DSC01798 (Small).JPG
total weight added to each chassis set is as follows.

the unmodded gold set added 22 grams with it's fresh candy blue finish.

the modded black set added 12 grams for it's bright bubble gum pink coating.

so less than one ounce for each set. i was expecting the weight that the powder coat added to be a little higher than this but i guess i was wrong. and this may help some of you out.

1 ounce = 28.349523 grams

so charlie you scale is right on the money :)
