Not real sure about the hurricane 550 but i think it is close to a 30 size nitro? I would think the HS85 being a micro servo would be too small. The 821 is a full size digital servo.

HS85 .
pecifications:

* Aluminum final gear
* Shock protected Pot
* Operating speed 0.16 sec./60° at 4.8 Volt
* Output Torque 3.0kg.cm (41.66oz.in) at 4.8 Volt
* Weight: 21.9g (0.77oz)
* Size: 29X13X30mm (1.14X0.51X1.18"

.
DS821 Digital Sport Hi-Torque Servo

Key Features

* Lower price point, but higher performance value
* New, longer-lasting plastic gear material
* Same size as standard servo
* Ball bearing-supported output shaft

Specs
Type: Digital Hi-Torque
Torque: 72 oz/in @ 4.8v, 88 oz/in @6v
Speed: .19 sec/60° @ 4.8v, .15 sec/60° @ 6v
Dimensions (WxLxH): 0.74"x1.50"x1.47"
Weight: 1.5 oz
Bearing: Single Ball Bearing
Motor Type: 3-pole ferrite
Gears: Composite
Application: Standard size-digital servo upgrade for sport pilot

If they will fit i would use the 821's if it was me.

Good luck.
