Well, I would rather say no. They are too tiny and underpowered for the full size DLG. May work on the tail feathers though if you aren't a power launcher, but we wouldn't recommend it.

​@@flightpointrc I bought my first (used) DLG this week but broke one 8g wing servo before maiden... Started looking for a replacement. Seemed like i'd have to pay almost the price of the used plane for 2 servos... I remembered that i have two ES9051 in storage. They seemed too wimpy for my plane but Your site gave them 5/5 x2 so i installed them. :p I´ll maiden in a couple of days and report back my novice opinion!

Indeed!

Thanks for the suggestion. Therefore, we already have the article that summarises all the tests that we've done so far flightpoint.co/best-dlg-servo/ You can also download a spreadsheet with all the results (make sure your ad blocker is off). The only test that we are missing, and that was requested by our followers, is the spring-loaded one. Just to emulate the torsion spring setup on the DLG tails. But after a few attempts we have made, the results were no different from the non-load one. Enjoy)

@@flightpointrc awesome! thank you.

Thanks, you are always welcome!

Hi, on this particular setup, I believe it was Turnigy Multistar 21A BLHeli_32. However, these are out of stock for the last two years, so not sure if you can get them somewhere. If you care about having the 32bit one, as I do, check the HAK RC 35A one - it's about the same size and reasonably priced.

@@flightpointrc awesome. Thank you

Occasionally, there it happens, but I've got reports that it can be fixed with programming. We are planning on using these servos in some of the Receiver-Ready gliders that we offer, and will make sure that we do program them to center as precise as possible.

A taller gear train makes a servo slower with higher torque (the motor is the fastest element in the gear train, so less gears = faster).

We've done tests with and w/o load on different servos, but since it didn't change the outcome, especially centering, we just stuck with the no load tests for now. So you can be sure that the servos will perform under a reasonable load on the same level.

My pleasure!

These are 5.5g, and very good. However, for a heli, I'd recommend going KST X06, Chaservo HV06, or AGFRC 6g servos instead of these JX ones.

yeah, it's a little loud on this one. But D47 isn't too loud over all...

Yeah, I would say so... The only drawback of these is that you will need to plan upfront whether you will use 1S or 2S battery and get the proper version HV/LV while KST X06 will work with either or regardless.

@@flightpointrc I work in animatronics, so we almost always use a switching regulator to keep a steady 6-7.4V supply voltage. I am very excited to put these into some projects. I have some X06 and A08 coming as well. Thank you for these reviews!

@@Veektohr You are very welcome, glad to hear that you find it useful!

Considering that Chaservo also has HV06/LV06 I'd rather compare X06 to these. DS06 is clearly a budget option.

@@flightpointrc The fact you're considering these budget option servos is insane. The quality is still there! Mind you, I'm in love with the KST's I'm using.

Yeah, absolutely. If you are up for a budget build - it will do the job. I had people around me using these in Snipes and Falcons with great success. And for the price, you can always have a bag of spares in a pocket ;)

You are very welcome!

Yeah, absolutely, the thermal drift is a known problem with a lot of servos on the market. We might consider performing these tests in the future and will share the results afterward.

Havent' tested it with Altis to say for sure, but in theory, since Altis don't work through SBUS, I'd say it won't work out of the box. However, in case you will add FrSky SBUS Decoder (SD1) between Altis and your Rx, it may. Your scheme should look like ESC > Altis > SD1 > Rx SBUS plug

Always welcome!

Totally agree!

Thanks for sharing!

Well, I have tested them with 2s LiPo, but not on a video. They work great, faster than you see here. I’d use them with no doubts!

Haha, I bet you won't feel any downside of either or)

We have tested the servos under load previously and there was mostly no difference in centering. We have noticed that if the servo is centering ok w/o load, it will most likely center well under load as well. So decided to simplify the tests and run them w/o load.

@@flightpointrc without load is no use. Servos never operate unloaded. I've just replaced 4 of these in my Stike 3 DLG because they were useless!

Thanks for your comment! Usually it's becasue of some extra friction in the pushrod linkage, which may happen in small gliders. However, it isn't felt in flight in any time

lol

Thank you!

Thanks for making such great products!

Just bought 4

@@electricburning Ha, that's awesome! Great little servo!

You are right, on the manufacturer website, it's rated for 4.8v as a minimum. However, as you see on the video, it works great at 3.7v, and considering this is the lowest voltage you should fly your 1s on board, it should be fine. We have experience running 4 of these in the Hawk DLG at 300mAh 1s LiPo with a great success as well as 2x in the Elf. So, feel free to use them for your build, you won't be dissapointed

Definitely a good improvement over the V5 one.

I was told they center better on 2s power but evidently not. I test my servos in a similar fashion. The best centering sample drives the elevator and the worst (within reason) the rudder.

@@kirkglundal4289 that's right, there is no difference in centering at low or high voltage. Usually, these center good for me as well.

Thanks!

Good catch! Yeah, on the bench tests it's clearly visible, probably some unneeded twist in the pushrod linkage that causes an extra resistance, compared to the left. Never created any issues in flight though.

You are absolutely right! The purpose of this test was to see how the servo will perform on a 1s LiPo. Nevertheless, this is an HV one and we use it often on the 2s LiPo directly with no issues. So this one seems to be a universal weapon ;)

@@flightpointrc what do you mean "an other story"? . It won't work at 5V?

@@maldjab6248 It will work in a range of 3.7 to 8.4v - haven't tested on the 8.6 though. And the more juice you provide for it, the faster and more accurate and more powerful the servo will be.

@@flightpointrc thanks for the answer :)

@@maldjab6248 you are welcome!

Good catch! These servos are manufactured under a dozen of various brands, as mentioned in our article flightpoint.co/best-dlg-servo/. So there could be different stickers on top, say HEPF D47, Ripmax SD100, Futaba FS 31 Pico, etc., but all the same servo under the cover.

@@flightpointrc Thank you

They will work just great! I had over a hundred hours with my elf with Hitec HS40 with no issues. It's a great choice!
