My scale is OK. I rechecked it several times. AE chassis are just very light (my TC5 was without electronics and tires around 460gr.).
My Lipo is 290gr., esc+motor are around 234gr., my receiver max. 10gr., the CPX tires around 100gr., the body is a HB 09X Lw with 70gr.. So I have relative light components. In my TC5 with titanium screws and Litemodz CVA's I had to integrate 170gr. of weight to reach the 1400gr. minimum weight.
I don't want to start a discussion here, but my opinion is, that the rules could be changed at least to 1300gr. minimum-weight. Or even lighter! After I knew the TC6 was coming soon, I converted my TC5 to a lightweight TC. In the end I reached a RTR-weight of 795gr. The car has the power of a normal 9,5t car and I had an overall driving time of 12 minutes with a 2200mAh 2S2P Lipo.
