KST X06 V6 Servo - 1.8Kg.cm 0.07s 6.4g 7mm

Product Code: KST-X06

(26 reviews)

Price: $44.61

Description

The KST X06 V6 is a 7 mm thin servo weighing only 6.4g. Perfect for discus launched gliders (DLGs) and many smaller models. The incredibly slim casing is crafted from 7075 aluminium alloy, so not only do these servos look fantastic but they are also very rigid and robust. The new V6 version has the same great specifications as the old servo, but is also programmable using a PC based or a press-button programming tool.

The KST X06 has a hardened steel drive train and a coreless motor capable of running all the way from 3.8V to 8.4V (1S to 2S LiPo) making these WV (wide voltage range) servos will deliver the power and reliability you need. Although some say this tiny servo is too small for 1.5m DLG aileron surfaces it actually has more torque on 2S LiPo than a KST X08 has on a 1S battery.

The accessories include four strong nylon output arms, two double sided, and two single sided, one of which is low profile. This means that when the servos are mounted one in front of the other the control rod of the front one won't foul the rear one.

Compact and light weight design

Servos used in a V tail E-Res model. Seem very precise with good centering. Plenty of power for application. Well worth spending the extra $ for quality. As usual great service from Hyperflight

The usual well packed and quick delivery for these tiny, jewell like servos. Bench tested only at this time but speed, power and quiet operation are as expected.

KST X06 Servo

Have used KST servos in the past with great results. These X06’s are super light and accurate. They suited my needs perfectly. Also prompt service from Hyperflight!

Great. Fantastic. Outstanding.

OK I am a fan of hyper flight, but if your not it's because you haven't used them yet. The X06 is a servo, it's just a servo. Wow no chatting with its friends precisely doing what it's designed to do. Powerful little fellow too. Recommended 😁.
Delivery UK to UK one day. Outstanding 👍.

Lovely little servos

I bought a couple of these to replace the 2 Bluebird AMG's in my Elf because the constant buzz of the AMG's finally pushed me over the edge. The KST06's are totally silent and just about fit into the Elf with the lugs still on (with some trimming of the very central leading edge. Lugs left on because I'll rob the servos from the Elf later in the year). I'm quite happy to give up a couple of grams for the extra quality that the KST's offer over the Bluebirds

KST X06 Servo - 1.8Kg.cm 0.07s 6.4g 7mm.

Great Service as always from Hyperflight. These servos certainly compliment the rest of the KST range with a look of quality and very quiet operation, they have been installed using the plastic frames which are available from Hyperflight, make sure you keep the four very small screws supplied with the servo as you need two to hold the servo in the frame(there are no screws supplied with the frame), Not flight tested yet but will work hard being installed in a D40 so time will tell.
Thank You

Review by: Tommy

Usually never buying Mk.I anything but wanted to have slightly smaller servos for elevator and rudder on my newly acquired Progress dlg. First impressions are good, the Kst works very civilizedly and quietly. Much smaller than X08 which helped fitting them in. No flying yet.

KST NEW 06

Just got a pair. I wanted the "iphone11" of small servos, and I got that. Small, quality, quiet, smooth. Fine on 1S lipo. Just what I wanted, the Rolls Royce of DLG servos.
