In ETS 21.5t spec, the car has a total weight now of 1215g with my 81g heavy bodyshell. That is 85g below the weight limit of 1300g. The car without bodyshell is only 1136g. That should be plenty of margin to play with weight distribution, and to have the CG as low as possible.

Looking forward to use this at the next ETS. I’ll need to order more of the Hudy tungsten weights for next ETS.

Here is what I used to get the car down to this weight:

301020 X4'24 Alu Flex Chassis 1.5mm - Swiss 7075 T6 (83g instead of 108g)

913300 Hex Screw 110° for 301020 X4 Chassis – Hudy Spring Steel (necessary for 1.5mm Chassis)

LRP UltraLCG StockSpec 135C/65C 5100mAh 7.6V Lipo (248g total weight nominal, mine is 245g)
OfficinaRC Titan UFS Screws (saves about 10g total)
Titanium Turnbuckles (saves about 1.6g total)
2x #990101 Hudy Titan Pivot Ball D=4.9 / S=5 / 3mm Hex (2) (saves about 1.2g total)
2x #990008 HUDY Titanium Ball Stud D=4.9 / L=8 / S=3.5 / 2mm Hex (2) (saves about 1.3g total)
1x #990006+#990004 HUDY Titanium Ball Studs (saves about 0.5g total)

Now it’s time to order some Hudy Tungsten weights, to have the ballast weight placed neatly as low as possible on the chassisplate, to come back to the ETS minimum weight:

293081 HUDY Pure Tungsten Weight 5g (9.5x11x2.5mm)

293082 HUDY Pure Tungsten Weight 10g (19x11x2.5mm)

293083 HUDY Pure Tungsten Weight 15g (19x16.5x2.5mm)
