SKYRC Wireless Corner Weight System
Originally developed for R/C cars, these scales also work well for 1:32 and 1:24 slot cars. Corner weights are one of those "small changes, big results" tools. Measures all 4 corners in real time so you can see front vs rear, left vs right, and diagonal balance while you make adjustments to weight placement.
The best part is the workflow. No display box, no wire mess across your workbench or pit area. Each pad connects over Bluetooth 5.0 to the RC Gears app (iOS 9.0 or above and Android 8.0 and above), so you get a full-screen layout that is easy to read at the track. You can quickly confirm total weight, corner weights, and distribution, then re-check after each change. There is also in-app calibration support if you want to zero things in using a 2000g reference weight.
The system is compact and travel-friendly. Each scale pad supports up to 2000g (8000g total), with 0.1g increments (0.01 oz). Pads run on CR2450 coin batteries (NOT included), and SKYRC notes up to about 30 hours of continuous runtime. Each pad is about 68mm x 68mm x 22.5mm (2.7" x 2.7" x 0.9") and about 70g, so it fits easily in a pit bag without taking over your toolbox.
