These 15g stainless steel weights are compact balance inserts sized 21 x 28 x 4mm designed as add-on tuning weights for RC chassis. They are intended for use with the NT1/RX8 carbon battery plate weight balance system and can be fitted directly to the carbon battery plate to extend the number of installed weights beyond the stock configuration.
When used with the carbon battery plate weight balance set, the pair complements the two standard weights to allow up to four total weights for a wider range of front/rear and left/right distribution adjustments. The low-profile design also permits mounting at alternate locations on the chassis using small screws or double-sided tape, offering additional placement options to adjust handling for specific track conditions.
Manufactured from precision-machined stainless steel, the parts provide consistent mass and durability appropriate for repeated setup changes. Sold as a pair, the weights are useful for lowering center of gravity and achieving finer incremental changes in balance without changing major component positions.
Fit these stainless inserts to broaden ballast choices and fine-tune chassis behavior for different track layouts without moving major components.
