new orca motors are light as hell, around 155. New revtech's are around 160-165.

The purpose of adding weights of the extras is give an idea of how much the parts weigh. When you try to lighten a car every little bit counts. Weigh an extra 60 grams and say you're ok with adding them to your car.

Some would say that the paint was added weight so they barely skimmed paint on the body. Once dry it only adds a gram.

Looking at the TC5 on the previous page, I just noticed it lacks the motor mount so 470 grams seems more accurate. That still the lightest I have yet to witness.

I am wondering if any recent chassis comes close to this. Anyone can weigh a box stock TC6 or 6.1?

What about swaybars? I don't see them also.

heretic

True, I forgot to mention them.

So... I have to ask : how much weighs an empty A700 ?

Oleg Babich

A700L at the same complectation as on your photo, but with all steel screws and with motor mount and with our battery holders:

485 grams with 3,0mm chassis
460 grams with 2,25mm chassis

These data are from my CAD and the simulation was very precise.

Nice threadidea heretic!
My old TC5 was also equipped with the thinner ISTC chassis that was available in that time.

I will prepare my TC6.1WC for another race series in the next days. The empty chassis will meet the scale then

Good thread idea heretic

I try for the lightest car to create options for using a large capacity battery and or weight distribution options. Oleg beat me to the weight numbers. A700 is amazingly light considering it has almost no plastic on it

Built a hb tcxx yesterday.
Everything was out of the box except for the turnbuckles. These were the titanium options and the set is 4g lighter than the steel ones. Car weighted at 507g.
Ready to run was 1346g with power hd servo, sanwa 451r receiver, lrp flow works team without fan, lrp x20 10.5 motor and lrp 7200 big mama battery as well as hb light weight mazda 6 mps. Tires were vtec g32. Minimum weight with these tires at lrp challenge is 1380g and with cpx tires its 1350. So everything is save :-)

Now as promised the picture:



I was too lazy to remove servo (50gr. says Sanwa), receiver (10gr. says Sanwa), servosaver, MRT transponder and battery hold downs system (RSD).

The car has only aluminium screws and titanium ball studs. Just a few screws are made of steel. So the TC6.1WC is quite heavy...

Full race ready with X20, Flow Works, Reedy 6500 Lipo, VTEC CPX tires and lightweight Mazda body it weights in at 1315gr.

Mi4 CXL, 549g

Sorry heretic, I should have read your thread first before I posted on the other one. Now I understand why you needed bare chassis weights. I'm using cheap $10 scales from ebay so I can't guarantee its accuracy as I only needed a stable reference. I included a pic of 2 2015 quarters as a reference to other scales.

This is an Awesomatix A800 carbon chassis with optional carbon arms. It's a full kit build without weights, electronics and wheels, with wheel nuts and motor screws. With the stock aluminum arms add 8.4 grams or 461.2g.

vapourtrail

Geeze! These pics came out awful! The 2 quarters read 11.7 and the chassis reads 452.8.

Dude, I think that a small summary of the information collected in the first post would be a great idea...

How do we take into account the variance in how the diffs, body posts, and shocks are built?

There is likely to be a significant difference in weight between oils, and how they are built (ex: green slime vs no green slime).

Many people sand the edges of their CF plates. How do we account for the difference in our techniques - and what CA glue we use to seal the edges?

The ultimate number that matters is how much the car weighs - Ready to Race.
