Turnigy 1258 vs PDI-6221MG

[@xblumentopfx]

One of the simplest and best tests I've ever seen. Great video.

[@tommy23490]

I bought a couple of those Turnigy 1258tg servo's and could not be more pleased.. I ran them in my Yeti's when I had them and the worked great.. What sucks is they were only like $23 when I got them now they are like $10 more.. Which is still a deal.. My next order I'm gonna get like 5-6 of them.. Another thing to note is the Turnigy 1256&1257 are good too.. Nice video!!

I really wish Jang would bring URC back up as that thread had a lot of useful information in it, as did a ton of threads on there. I bought one of these servos to have as a backup a few months back and have finally gotten around to using it, and mine will not center itself, upon further inspection you can turn the pinion coming off the servo about an hour in either direction before the servo motor catches. It was only $11.99 so I am not going to complain to much about it, but it seems to have better speed and torque than the two Traxxas 2075 servos it replaced in my Summit. I am contemplating getting the 4 pack of them as $39 for 4 servos is such a steal.

jang is such a great content creator

[@peileed]

thanks for this man, here I'm wondering why my 20kg motor cannot lift a few grams...checked the voltage and seems to be fine

[@adithionugroho3158]

Can you tell me your arduino code for jx6221mg move 90 degree ?

[@viktortech4931]

which one is better in general the JX servos or the power HD servos ?

[@billdelong]

JX Brushless are better, PowerHD are very good too!

[@ninguemrjba]

Hi, do you known its power consumption on load (using its torque)?

[@billdelong]

I use a power analyzer: www.ultimaterc.com/forums/showthread.php?t=149200

[@ninguemrjba]

So, what is the 6221MG consumption on load? Thanks!

[@3dprintwiz378]

I'm about to buy it for my robot arm, do you have an idea of its PWM specs, maximum and minimum. Thanks for the review.

[@billdelong]

no clue other than what's posted on the product page

[@1000littlehero]

Hello Bill...Does this servo function using arduino uno? i try my coding with servo mg995 worked but on this servo cannot... can u help me?

[@kodratwirawanfauzi3984]

same with me, from the article, jx pdi 6221 need high current maybe

[@manuxs9]

Good afternoon. What is the code to control the servomotors or how to cotrol this?

[@billdelong]

I'm using a generic "servo tester" available on eBay

[@giacomozecchin6841]

hi bill can you tell me if these digital servo can be used with ARDUINO ? thanks

[@billdelong]

I don't have any experience with ARDUINO, I guess the question is if ARDUINO supports digital servos or not?

[@1000littlehero]

hello giacomo... can i ask u on how to opearate servo using Arduino? What is the coding? Do you manage to operate it ady?

[@lindeezylo6095]

Would you recommend the jx pdi Servo for the zd racing 1:8 buggy zre?

[@billdelong]

Yes, I think it would do well

[@pirkes1]

I have 5 of them on a 3D airplane and face some centering problem. Does anyone had those problems too? Is there any way to fix it? Thanks.

[@billdelong]

if the servos are more than 6 months old before you started experiencing centering issues, then chances are the gears have slop from excessive wear, I would take them apart and inspect them... replace gears if necessary.

[@marcio6498]

Can I use Jx in a hexapod?

[@fadi.almasalmah]

Hi .. Does any body have JX Servo PDI-HV2060MG ? I need the exact Dimensions of the motor and distances please ! I really need them now for my graduating project ... and it will not arrive before 2 moths from now! any one have an idea please??

[@interman7715]

Hey Bilk could you do a torque test on the 6221 ?Thanks

[@billdelong]

I don't own this servo anymore, I have since upgrade to the JX aluminum case brushless servos instead, they are perfect for all my 1/8 cars :)

[@interman7715]

No worries .

[@BradleyNeilSipaun]

how is the jx servo? would u recommend getting?

[@billdelong]

yes, the coreless and brushless versions are doing well for me, best servo for the money right now!

[@silviabeatriz5917]

hello truly the servo is good I'm asking you why I'm going to use it in a cuarte scale model! greetings Horacio

[@billdelong]

not sure if this servo is rated for your model, I would contact the manufacturer for your car and see what they recommend for minimum torque requirements.

[@kodratwirawanfauzi3984]

how much load do you use on this servo?

[@kodratwirawanfauzi3984]

pls reply

[@billdelong]

in the video, I used 5lb @ 1in off center = 80oz/in of torque

[@kodratwirawanfauzi3984]

i wanna ask more, how much operational current for jx pdi 6221 mg ? i use for atmega but it doesnt work? pls help me

[@billdelong]

I don't own this servo anymore, I've upgraded all my JX servos to the brushless version... anyway, I've never had any issues with my 2A BEC's on all my cars.

[@sourabhjangid7722]

Delay is very short

[@tonyallen8626]

there not lifting the weight their just straightening the wire, you need string that doesn't stretch

[@billdelong]

huh? the wire remains straight, the hole is exactly 1" from center of servo arm, lifting the weight, this is how you measure torque

[@tonyallen8626]

+Bill DeLong as soon as you twist wire around like you have to secure the weight it has a spring affect that's why your weights are swinging all over the place instead going straight up and down

[@billdelong]

@@tonyallen8626, they don't swing on the very first upward motion, that is the net effective test of torque... when I release the load and swing it back down quickly, then they start to swing, no big deal... if you see some of my other videos using the same method, there are some budget servos that can't lift the weight at all which proves the stated ratings for those servos were bunk.

[@JAWS1376]

Bill, I wanted to ask you if you ever had any problems with the JX. I bought one just to replace the crap servo on a Turnigy Trooper. I didn't need anything special it's mainly for my kids. The trooper is cool, but I thought the JX would be a cheap, great upgrade. The first one I bought would stick to one side. I guess the best thing to do would be to show you. kzbin.info/www/bejne/Z4LEkquPiJWshdU Surprising Banggood sent me another one and this one is a little better but still sticks to one side once in awhile. Could it be controller/receiver? I have Turnigy GT3X and whatever receiver that comes with. thanks for any info!!!

[@billdelong]

+JAWS1376, skip to 1:45 in my video and you'll see that I get a similar delay, not sure what the deal is with that, but fortunately I don't drive a car like that and don't experience that problem under normal use :D

[@JAWS1376]

+Bill DeLong would you consider it broken? even the no-name servo that came with the trooper would turn the truck. imagine coming out of a right turn, but the wheels never turns back. I can handle a little delay but not a 6+ second delay I've never seen anything like it.

[@billdelong]

+JAWS1376, yeah that's definitely strange, not sure if it's the servo, or if the servo is drawing more current that the BEC can handle? It's behaving like a brownout, do you happen to have an external BEC available? If so, I'd give that a try and see if the root of the problem may be that the servo draws more current than the internal BEC can handle? Maybe hook up a different servo to Ch1 and see if it can continue working without brownout when the PDI servo freezes, that will tell you if it's a brownout or if the servo is simply freezing up independently from the BEC.

[@JAWS1376]

+Bill DeLong Bill I appreciate the help. I hooked up the servo to my Talion's ESC and and it works perfect. I guess in the back of my mind I knew the Hobbyking Trooper (electrics) was the cause. man, what a big waste of money. I bought the Trooper for my daughter for Christmas and it's run fine for about 15 min. anyways thanks again!!!

[@billdelong]

+JAWS1376 glad to hear you got it figured out, those ESC's that ship with many of the HobbyKing RTR's are often under powered and anytime you upgrade any other component, then you probably need to upgrade all the electronics to play it safe.
