This machined aluminum servo mount replaces flexible plastic fittings on TRX4-scale trail crawlers with a solid 6061 T6 plate, lowering flex where the horn meets the chassis. The part holds the servo horn more rigidly and, combined with countersunk fasteners and shims, helps preserve correct horn alignment under load.
Fitting is straightforward but demands attention to alignment: use the supplied countersunk screws along with the provided shims and washers to set the servo height and remove any slop at the horn interface. A firmer mounting point reduces the need for repeated endpoint trimming and improves steering predictability at crawl speeds.
This upgrade reduces mounting flex for a more consistent steering feel and is suited to TRX4 trail crawler builds that demand precise low speed control and repeatable steering geometry.
