New Servos from KST!!

KST is bringing us some new servos for our F5J planes with the HS08. They are nearly as small as the X08, but nearly as as powerful as the X10mini! These bad boys are going to be a perfect match for most 5J planes. I received some pre-production samples to check out and the 7075 Alloy case looks and feels amazing. These have been running smooth and precise on my bench tests thus far and I am really excited to get them into a wing soon.

The HS08 will come in an A and B version with the difference being the mounting tabs made to accommodate wing or fuselage mounting. The case measures out to 24mm x 8mm x 25.25mm and the weight is 11g. The gears are hardened steel driven by a coreless DC motor. I don't have pricing or availability info yet, but I wanted to get this posted to let you guys know about them as soon as I could. Here's the spec sheet:

  • Rated Voltage: DC3.8V-8.4V
  • Voltage Range: DC6.0V
  • Stalling Torque: [email protected]
  • Rated Torque: [email protected]
  • Stalling Current: 0.68A
  • Rated Current: 0.25A
  • No-load Speed: 360°/S
  • Rated Speed: 250°/S
  • Default Travel Angle: ±60° = 120° total travel
  • Operating Temperature Range: -20°C......+65°C

Look for More Info on the KST Site Here When These Get Posted

By the picture I'm guessing not interchangeable mounting holes with current X08?

F3K nothing. I see F5K written all over them.

Well, not really all over them. It's in really small print, down near the bottom. You have to use a loupe to see it.

These are going to be awesome for F5J models. Right between X08+ and X10 mini.

I like the look of it. So appears they took a 08 and simply enclosed the motor. Really hope the cost is sub $40.00

Like to see a review after they are in a wing and flown!

The specs are quite different than the x08 from what I’ve seen in both torque and gear train strength. I doubt it’ll be below $40.

Which fits the X08 frames too!

This may be old news but gear-sets are now available for the X08/+ so I went ahead and put X08+on the flaps of my latest build. I prob would have gone with the HS08 had they been available as I was considering the X10 minis.

Maybe I'll upgrade to the HS08 depending on how the XO8+ do.
