Tresrey HT450 & HS400 V1.1 servos
Tresrey introduce the V1.1 versions of their HT450 off-road and HS400 on-road servos. They feature an updated motor for more initial speed, increased holding power during cornering and also more efficiency. All other features such as metal gears and the plastic/alloy heatsink case remain the same.
