Thread: MKS DS95 servo, 'very impressed

I recently bought an MKS DS95 servo from Phoenixtech to try on the tail of one of my 450s.

I just got a chance to try it today and I am very impressed. I must admit I am surprised at the difference the speed of this servo makes because the Acerlab is a respectable speed already. The MKS just feels super 'locked-in' and responsive.

Until now I have been using an Acerlab D12-MG on the tail and it has actually been fine and up to the task so far. But the MKS is on another level.

Without changing anything else on the heli I was able to run approx 20% more gain and still so sign of wagging! (at this point it was nearly at max gain using the gyro menu in the DX7 and solid as a rock).

With the Acerlab servo a pronounced wag would begin at a value of 81. I was running the MKS up to 99 and still no wagging (keep in mind that in the DX7 in the gyro menu the gain runs from 0 to 100 with 50-100 being HH, 50-0 for rate mode).

The current setup is;
Trex 450 SEV2, GY401 gyro, servo ball link centre at 7.5 mm from the centre of the shaft. KBDD tail blades, Align 325F and 3D pro mains, KBDD paddles. Stock Align 430X motor and Align ESC.

Maneuvers included aileron rolls, hovering and FF flight both upright and inverted, flips and loops, stall turns etc. So nothing too crazy

Speed figures by comparison are;

Acerlab D12-MG - 0.083sec @ 6.0V, 0.10sec @ 4.8V
torque 1.8kg/cm at 6 volts

MKS DS95 - Operating Speed (4.8V): 0.066 sec/60° degrees at no load
• Operating Speed (6.0V): 0.053 sec/60° degrees at no load
• Stall Torque (4.8V): 2.44 kg-cm (33.9oz/in)
• Stall Torque (6.0V): 3.05 kg-cm (42.3oz/in)

Interesting Sheryl. I am trialling the MKS DS8910 on my 450 Sport. Very quick and rock solid with the Quark, if a bit big!! But eventually, there will be another fuselage on it and bigger tail blades.

4.8V Speed 0.05sec/60degrees

Yeah the DS95 is blindingly fast (or it sure feels like it anyway). I bought it some time ago but with one thing and another I didn't get round to installing it till last night. Also I wanted to fly last time out with the Acerlab servo and find the point at which it started a fast wag.

I can only describe the difference in general as just a feeling of being much more locked-in and solid and I literally couldn't make it wag!

What was the cost of the servo please sheryl?

here is the price, special offer is still available at the moment. if you just like to try one ds95, it will be £40 including delivery.

thanks

Hi Trillian,Did you have to make a special plate to mount the servo.
Many Thanks,
Marty,

I just bolted it straight on. I have the Align blue metal servo mounts on the boom (Trex450SE) and it just goes on exactly like the previous servo.

Many thanks for that Trillian.
Yours,
Marty.
