RC Basics - What are Dual Rates? (D/R)

[@RcMcNutt]

Fantastic video. I really enjoy every minute of your vids bud. Clear, intelligent, well thought out and visual aids! Perfect for the new pilot. Thank you for taking the time to do these.

[@andreatanzi3191]

Thank you for the very simple explanation, much appreciated !

[@jasonlara]

A visual so simple, yet extremely effective. Done right.

[@Painless360]

+Jason Charger Thank you! :D

[@JaredElliott1]

Great explanation and the physical setup with the servo really brings it to light.

[@shotzsmith4854]

So simple. Watch flite test and they couldn't even tell me this simple stuff. Please make more videos. You just earned a subscriber

[@InvisiMan2006]

How does this differ from steering endpoints? I have both settings on my controller (rc truck) and this video explains how steering servo endpoints work.

[@Painless360]

I am only just getting into radio controlled cars so don't know how all that works yet. Sounds very similar though doesn't it?

[@martinpaksi]

great explanation, perfect visualization... thank you...

[@weewick7779]

Still helping new people in 2023, i never understood what it does.

[@alvinostime-lapse3038]

thanks for simplifying it to the max...........

[@umarkhan-ze8qf]

Great presentation, thank you.

[@fcmstreetfight11]

damn thankyou Ive always wondered what it meant

[@Bob_Burton]

Very clear, and I like the excellent visual aid in this video :-) One thing that annoys me is when people refer to "switching to dual rates" when what they mean is "switching to a lower (or just possibly a higher) rate.

[@Painless360]

UKHeliBob thanks Bob, thought you'd like it ;) Happy flying sir!

[@finnhoffmann3754]

You're talking about%. In my manual it says e.g. "Elevator" High Rate up 10mm, High Rate down 10mm. Should I measure the movement of e.g. "Elevator" from neutral and adjust% to the measurements fit?

[@Painless360]

Yes. See my OpenTX simple plane setup video... best of luck

[@buckreynolds1779]

good job ...years later ...good job

[@alfonso333]

Excellent video, lot of help for me

[@celestekwasman5649]

"I read the manual, and was really none the wiser..." is a perfect description of my entire rc experience, up to this point. lol

[@Painless360]

Yep, lots of names for stuff with zero explanation about that they 'thing' is for! :D A big part of this channel is aimed at those who then Google that 'thing' to figure it out. This video is an example of that.. Best of luck!

[@fklotaloi]

Sir, How can I decrease the twicyness of my heli default settings lets say XK110 heli ? I want the servos will move slowly (like slow motion ) not too fast . Wht functions of the radio would do so? Thanks

[@Painless360]

Expo is where I'd start... Helps calm the sticks around midpoint.. Best of luck

[@hankus253]

Like the old saying a picture is worth a 1000 words. Reading about dual rates or previously expo, is one thing but your visual presentation is excellent in bridging what it is and what it does. Thank you, thank you.

[@6thsun25]

Why is there only dual rates and not like triple or quadra rates?More advanced rc transmitters have more than dual rates?Maybe i find 80% also very aggresive and i want to set it to 60% or 68% .Can i achieve this with any other setting like epa throttle?

[@Painless360]

You can setup as many rates as you like with modern radios.. Check out the Opentx mix school..

[@rubens13]

Excellent video, very didactic!!!.....thanks for sharing!!

[@adnanulhaque8846]

This video in combination with ur other video on exponential is very good one. I m new to RC hobby and just finished building my first F450 quadcopter.....learning how to fly, just focussing on hovering...currently expo=0 in my TX (flysky fs-t6 mode1) ... I believe if i enable expo then it will give me more control on hovering as i cannot control my quad 2-3 ft above the ground...i m more comfortable when quad is above 10 ft...so, enabling expo will give me better control over my sticks when my quad is just 2-3 ft above the ground ...is my understanding correct?

[@mohammedabrarahmed3299]

Thanks for the info

[@bradfordtownsend9698]

Brilliant, thank you

[@MichelleSmith-ce2qm]

What would you suggest duel rate should be for a edf 70mm f16 jet

[@Painless360]

Depends on the model... Happy flying

[@GryteselvFPV]

just lovin this simple visual way of explain the subject!

[@jknows170]

Thank you. Great job explaining. Helped me a lot

[@DeadmiXSoft]

Perfect. Thank you for this. I've got a dx6i and will fly a Quadcopter soon. But in my manuals is nothing explained to it. Great video. Now I can try to figure out what I need.

[@johnsargeant2041]

Thank u for braking it down in that way.. Very helpful..

[@Cosme422]

How can I correct one aileron throws more than the other on spektrum receiver channels 2 and channel 6?

[@Painless360]

I would use the travel/throws in the radio as a last resort. Use the adjustment in the physical linkages from the servo to the wing to get them both the same. See kzbin.info/www/bejne/a2TNk4mZgKaHpMU

[@rv5227]

Thanks dude

[@thelongestday64]

Brilliant! Very visual! Thank you!

[@Tickleme3090]

Thank you very good explanation!

[@NilsRohwer]

Very clear and helpfull, thank you.

[@BogdanBershadsky]

Hey, could be my car faster if I will buy controller with dual rates? Or all controllers use max power by default?

[@Painless360]

Throttle channel limits are not something you use dual rates with. The limits are set via the ESC calibration.. Best of luck

[@BogdanBershadsky]

@@Painless360 thank you!

[@Ken_412]

Excellent, thank you.

[@stephensweeney5167]

Hi again... Quick question about DR and Expo for Quads... I have flown planes for many years... Just got into quads this season. Is it better to setup expo and rates in the transmitter or the Mission Planner software? I don't see a place to get a switch working from Mission Planner to switch between rates, but probably has something to do with the CHX_OPT... I know some of the radio setting can confuse the Flight Controller. I am currently running a Pixhawk... But the question would be the same for Cleanflight or other FC software.Thanks Steve

[@Painless360]

The general rule for expo is to set it on the flight controller as it provides a much smoother result. I use both as I also like the option of changing it easily on the radio too.. In the latest series we are doing (iNav) the advice is remove all D/R and Expo from the Tx and let the flight controller handle it all..

[@Rick9482]

Fantastic visuals. Undoubtedly the best use of a toothpick I've seen this month. I've subscribed!

[@Painless360]

Thanks Rick, happy flying!

[@chrisgifkins373]

Thank you soooo much for this video. Have been trying to understand what these settings are for ages. Now that I know what they do, I can change them safely for my flying skill. Thank you Thank you Thank you

[@Painless360]

You're welcome! Please see the 'Introduction to Remote Control' for more of the basics explained in more basic terms for new pilots (and some not so new!) Happy flying!

[@markbradbury7959]

nice clear video but im still a bit confused..... so lowering your rates is like reducing the resolution of the tx controls.... im trying to fly my first multirotor on a kk2 board and I read somewhere its best to send the best resolution from the tx to the kk2 but this makes my tricopter hard to control. do I need to make the adjustments on the kk2??

[@Painless360]

The endpoints do not affect resolution, just the total travel on the channel. Typically a channel will move from 1000 to 2000 microseconds (1 to 2 milliseconds) with the midpoint being 1500 microseconds (1.5 milliseconds). Dual rates just limit how far the channel goes towards the 1000 and 2000 values. Stick scaling on the KK2.0 is about how aggressively the KK2 responds to the stick input. The lower the 'stick scaling' setting on the KK, the easier it is to fly but harder it is to do flips and rolls. Hope this helps. Happy flying!

[@ratelmike8825]

I'm an experienced flyer myself but I never bloody understood all the jargon like dual rates or exponential either. Even now as I head back into the hobby I heard unboxings and setups of a new plane and the waffle of these terms never being explained, so thank you very much. Excellent video. The yanks just waffle on soooooo much, it's great to watch someone get right to the point!! Hope you are still flying.

[@flatinnh1918]

Top shelf mate.

[@ambermeows150]

So the low rates is equivalent to rc rate in clean flight? And high rates is equivalent to rate?

[@Painless360]

+Amber Meows not really. Rates on the radio are simply about the travel of a channel. Happy flying!

[@ggweslie4145]

[@Klipschsynergyf30]

Can you please post a video explaining expo using the same servo + diagram?

[@Painless360]

We have one in the 'Introduction to Remote Control' series already. Best of luck!

[@theobuiatti6420]

Good one thanks..

[@garyvale8347]

Great video....finally someone who made a video explaining what D/R and Expo means ..... I have the DX6 Tx ...is it alright if I set up my duel rates and expo settings on my 3 position switch "G" instead of a 2 position switch?.... 1st position 70-30 % , 2nd position 100-30% , 3rd position 100-0%.....I am flying a helicopter .....( Blade 200 S ) what do you think.....thanks....Gary

[@Painless360]

The settings in the manual look good to me for a starter for ten. I'd never fly a heli with no expo at all, I'm, not that good a pilot..

[@garyvale8347]

OK.....I am adding expo back into the 3rd switch G position.....I also moved the " panic " feature from the " I " button, over to a 2 position switch ..."A'...do I still need to keep the AUX 1 reversed?

[@JT-jy2sy]

I have been watching your CC3D series and that was all I needed to build my first racer 250 quad. Brilliant series! A question relating to this video. How does this works with CC3D? I have dual rate setup in my transmitter (radiolink at9). What is the relationship between dual rate in transmitter and the input scale bar you see inside librepilot RC input tab? I am a bit confuse. If you move the stick of the transmitter to the furthest point the RC input scale reading will go to the max independent of the dual rate setup in the transmitter . Many thanks in advance.

[@Painless360]

+Jack Truong I would never used dual rates on a flight controller, this is more for fixed wing models. Once the flight controller is calibrated to your radio you should only have to alter the expo.

[@JT-jy2sy]

+Painless360 very good point. Many thanks.

[@Jimgoodwin846]

On a plane-what would be a good place for a beginner to start with dual rates? I have the dx6 transmitter. I am a beginner. Only 4 or 5 flights on my sportsman s trainer that practically flys itself. I built a Flite Test Trainer...that I would like to set up with dual rates. Thanks Jim

[@Painless360]

It really depends on the model. Most models have a range of movement in the manual for the control surfaces so I would normally set the high rates for the throw in the manual and set low rates for about 60-70% of that movement. Also worth adding some extra expo to the lower rates too to help with fine control.. Happy flying!

[@Jimgoodwin846]

Ahhh, I’ll bet that’s what the high/low gauge is for...thanks

[@nutleighgrove3658]

Another excellent video - thanks! I’m a bit confused with my Align T-Rex 450 heli: As I change the the rates, for example, on the tail (blade pitch/rudder), the throw distance remains the same but the servo response is much quicker or slower. This kinda makes sense as it’s the “rate” of change. So could you tell me why your video refers to the ‘distance’ of travel? 👍🏻🚁

[@Painless360]

Have you got any flight stabiliser or gyro on the tail?

[@nutleighgrove3658]

@@Painless360 Yes 👍🏻 It comes with the standard “Align MiniGRS Flybarless System”. It’s nicely stabilised. On the bench, I can flick ‘throttle hold’ to see the tail blades change pitch left/right. It confirms what I experience in flight. The servo mounted on the body has a long rod to the tail. This alters the angle of the tail blades while they spin the same direction & speed. Sorry if you already know this 🤩. So basically the same as the rudder on a fixed wing plane. My point is that playing around with rates, I can see at say 10%, the servo takes a couple of seconds. Where as at 100%, it happens in a split second. In each case, the distance of travel (or throw) is identical 🤔

[@Painless360]

Then it sounds like the way that the flybarless unit is affecting how that all works. I've not used that one here. Best of luck

[@nutleighgrove3658]

@@Painless360 Thank you, it is a bit odd! “Rates” meaning speed of change does make sense if you think about it. Can you confirm it refers to the distance/throw of the servo, not the speed at which the servo moves? 👍🏻
