Hitec D845WP WV Mega Scale Torque
Brand: Hitec
Part No: 2221305
In Stock: Usually ships same day
The Hitec D845WP WV Mega Scale Torque servo (part number 2221305) sits in Hitec’s D-Series and blends industry-leading high-resolution control with ultra-response performance. Its 32-bit MCU and 12-bit ADC deliver exceptionally smooth movement and extensive programmability, while the broad 4.8–8.4V input range supports common battery chemistries without adapters or regulators. A 15-tooth HD output spline with 3mm hex screw ensures a secure interface for heavy-duty control linkages.
Designed For Demanding Use
Engineered for strength and longevity, the D845WP features durable steel gears and dual ball bearings. Waterproof construction and dust resistance rated to IP67 help protect the internals in harsh environments, and an integrated heat sink assists motor cooling during extended operation. The result is a robust servo that combines durability, quality and monster performance.
Advanced Control Electronics
A programmable high-response digital amplifier with MOSFET drive underpins the D845WP’s precise behaviour. The 4096-step resolution, teamed with the 32-bit MCU and 12-bit ADC, provides refined, repeatable movement and rapid response. The wide operating voltage range further enhances flexibility across setups that demand both torque and precision.

Yes that looks like it should fit
The stock LOSB0884 servo shows a measurement of 66 x 57 x 30mm. This servo measures 66 x 62 x 32mm, so seems very close.
Yes, we have seen customers running these in the HPI Baja 5B.
The 5765 is lower spec and non waterproof.
