Should we start testing Servos on this channel similar to how we run performance tests on LiPo's. Do you think torque and speed values are accurate to a manufactures spec?
Yes, please.
Because most manufactures lie about performance.
Please, do science this!
Yes, please!
Include the cheap ones from Ali and HK.
Yes, pls
I have only started with RC hobby this year and I've ordered one servo so far as a replacement for RTR car. This vid popped up at the right time for me 😁 Thank you.
Perfect timing!
Really helpful. Thanks!
Glad it was helpful!
Digital in any critical application or expensive model, they are more money but a failure could cost more. I remember when digital came to 1/8th scale racing what a difference, better steering and less failure. Analog for cheap foamie planes that you are glueing in the servos, keep it cheap. Larry
For my 1:10 rc buggies, the Power HD R12s, low profile is my go-to servo price vs. performance.
Nice they look good
The issue I see is they seem to get the jitters a lot quicker than the magnetic pick ups
I’ll have to try these for my arrma infraction and arrma typhon (one is for dirt, one is for street)
Nice!
I just tried promodeler servos. For 400% more than an amazon miuzei i was pretty disappointed. Thing is louder mostly. Same goes for savox. The amazon red servos are pretty bad ass for $12.
Good to note. I haven't used promodeler.
Those Amazon surveys have been crapping my experience. My go has been hobbystar Servos. Brushless for $60
That sounds very good!
So which digital servo do you use or recommend?
I use powerhd in cars and boats and hitec or mks in jets.
How do you figure out the refresh rate/ operating frequency of a digital servo, if it is not provided in the specs?
Or what refresh rate/ operating frequency do you set in the transmitter, if that information is not provided?
Video coming out soon for this. If I don't know I ask the manufacture or leave it as the standard rate good for all servos.
@@RCexplained I like to swap the provided RTR transmitter and set up new models to run on my programmable Flysky NB4+. But when I do so, I need to input the servo's refresh rate, which is often not provided. So far I have had no responses from manufacturers.
But what would be the "fits all servos" frequency? 50Hz? Wouldn't that mean to give up the advantage of a good response time?
Can't wait for that video of yours! 👍🏻
@@christiannasca3520 Shame he wouldn't respond I was curious about same and looking at the same issue myself, I got a digi servo but cant figure out what hz it's rated for, makes me wonder it's not really a digital servo...
@PatrickBaptist Actually he did post a video about this topic after my question. I don't have it at hand right now. But you can surely find it on his channel. It is a recent video from a few weeks ago.
Everything is a waste of money if the servos aren't properly setup. I.e. there is no point in paying for digital servos when you have huge mechanical leverage but you reduce rates in your transmitter to 25%. You want to have your travels set to 150% or whatever maximum your TX allows and then if you want to reduce travel, you would mechanically adjust your linkages like using a lower position in your servo horn to reduce the leverage. This ensures you use the maximum torque and resolution that you paid for.
A cheap butter knife will always perform better than a surgical scalpel for buttering your bread.
Lesson - don't just throw money at things, it could be worse if you don't understand the fundamentals.
If you only use or mainly use "low rates," you are wasting money and performance due to incorrect setup.
@Toolbaggers Have you ever been accused of being an annoying know it all?
My rc crawler performs well with a digital steering servo set to 120°.
Really shines with a remote control transmitter having alot of tweaking ability.
Noise is the only downside
True, I normally don't hear anything while running my rc.
For 1/10 power hobby 209 work great
Nice servo!
One benefit of analog servos are they are much quieter than buzzing digital servos. Another benefit of analog servos are that they might be considered "cheaper" and thus will have plastic gears. Plastic gears have less slop out of the box and they don't wear out as quickly as metal gears. Plastic gears are also much lighter and it is cheap to replace stripped plastic gears.
You need to improve your videos. Most people, including me, won't bother watching 7min35s just for 5 reasons that could be read in 5 seconds. Add markings to the video's timeline so we can then dive deeper in the specific subjects that interest us.
Do agree, the channel can add chapters to where the 5 talking points are, and label them. Putting overlay keyword text of the 5 Points will help greatly too.
I can add chapters again. I did this year's ago and analytics showed that it wasn't used.
@@RCexplained That would be great! :)
Increased precision of a digital servo cannot be felt if the metal gears have slop!
Bashers and lazy circuit flyers don't need to waste money on top gear when the limiting factor is the operator. I.e. if you NEED to use a gyro like AS3X, use your time and money wisely to instead improve your skills.
