SRT T45 HV Coreless Digital Servo - 625 oz-in, Metal Gear, Crawler/1-8

A high-torque coreless digital servo for 1/10 and 1/8 crawlers that need serious holding power. 555.5 oz-in (40 kg-cm) at 7.4V, and 625 oz-in (45 kg-cm) at 8.4V on full HV. When a lighter servo hunts or folds on a ledge, this is the upgrade.

Why it is worth the money

• Coreless motor - smoother and more precise off-centre than a cored servo in the same class
• Steel and aluminum metal gear train with dual bearings - built for repeated stall loads
• CNC-machined aluminum case that sheds heat on long technical crawls
• Direct-drive potentiometer with a 2µs dead band, SSR-mode compatible, 25T spline
• Programmable high-torque HV coreless - standard size so it drops into most bays
