Hacker Ditex Servo Review

kg isn't a measure of torque. Ncm or oz-in are the common torque measurements (you could do kg-cm or g-cm as well). Which servo are you referring to Drac1?
The 1609 hits 70-80% of available torque holding my Allure through a 2-of-4 point entry Split-S. That tells me it's too small for more advanced KE flight.

The 1609. I would be confident with that on rudder, but it's too heavy.

1609=62.3g, 0606=22.7g, 0806=40g, total weight in my allure = 187.7g, that's less total servo weight than any other combo of servos I've used in the past. Add 10g to get to the 2211 with 19.3 kg-cm torque at 7.4v. Keep in mind that given the throw distance needed on the rudder you are going to have more than a 1cm control horn on the servo and the corresponding resulting loss of force to the rudder cable/control rod depending on your install. I think I have 1.5inches (3.8cm) from center to each rudder cable, so with the 1609's 13kg-cm we're talking about 3.4kg of effective force on a very large and not counter-balanced rudder. Again, note the %-age of available torque being used just to hold my Allure level through a 2 of 4 at 1:20 in my flight. Now, imagine asking that same rudder servo to hold through a KE loop!

I fly GP. In my Xareltoo bipe, I use JR NX3421 - 30g, on ailerons and elevators. MKSHBL575SL - 53g and 16.8 kg/cm on rudder. It knife edge loops and knife edge figure 8's no problem. I have a new JR/DFA 3911 for the rudder. 20 kg/cm, 34g. Yet to be fitted.

Ail - JR/DFA 3911 x 2 = 68g, elev - JR NX3421 x 2 = 60g, rudd - JR/DFA 3911 = 34g, throttle - JR HV169 = 22g.
Total = 184g. Take out the throttle servo and it's 162g.

Thanks for the info, guys. My intention is to stick with the Ditex, if feasible. I did not find the 2211, but I do see the 2612S, which weighs in at 65g with 368oz/26.5kg/cm. I will probably go for this one.

question?
I am using the Ditex servos on my Proteus, and when I went into device explorer and converted the alternate pin output from servo to ditex, I can now see the telemetry and the servo works, but the transmitter beeps this:
and, it will do each one, one by one, (pins) that are ditex.
Why is it doing this?
