This is absolutely the best explanation video for dual rates & expo I've come across!

I want to thank you for the way you share. Two months ago I got my first cp 450 blade. Going from the 120SR to this was a bit scary but once I dragged myself around with the training gear for about a week I finally started to hover. I watched your video on starting with a cp heli and it helped very much. I now have about three hours of nose out hovering and moving left , right. Taking it slow and easy with no crash as of yet. Thank you for explaining the radio info in a way that I understand. TY

THANKS FOR THE 101 CLASS ON DR/EXP,FOR PEOPLE LIKE ME JUST STARTING THIS IS AWESOME.THANK YOU SO MUCH.

Excellent description! Hits the points in real talk and clears up our confusion of the settings and why we use them! 9/10**

When you explain it ,it's easy ,good clear teacher ,greetings from UK 🇬🇧

FINALLY! Someone who can speak plain English when explaining D/R and expos. Thank you very much for the explanation and insight!

Thank you , very understandable and makes thing very clear learned a lot from all three of your videos now I understand how to adjust my tx. thanks again.....

This video is two years + old and still helping people out. Thanks for breaking it down. I felt like I needed confirmation and a visual and I got it. It'll also help me explain it to a friend :D. Of course i'll link him to this vid as well. Thx for posting.

Thank you, You are the first person that actually explained this so clearly that I totaly understand. Great vids...

Thank you so much. You really helped me understand what they do.

As a newbie to rc helicopter flying, your explanation about DR/Expo is first class. Thank you.

thank you frank i'm glad i can help nice people like you

Thankyou , had so much confusion regarding this. read and watched a few pieces but was if anything more confused. Your video has solved all that. very clear and well explained.

Thanks Ray for the video, your vids are awsome i have been learning so much from them.

best explanation of this topic I've seen. I sort of had it figured out this video just cements that. Thanks alot, subbed too!

Awesome video TY so much. I set up higher expo and wow now I can fly much better :)

Thanks for the videos, Happy Christmas to you.

Thank you So much for this info.

amazing! thanks for this awsome tutorial!

Very useful for a beginner with a chinglish instruction manual!

Thanks, just I figured. I have been flyin 6 ch. heli now for 6 months. I have kept all expo and rates at 0. The peoblem I have is not being able to stiffen up the throttle stick enough. So when I turn my throttle changes. Do you have any ideas on that?

Hi Ray, Thank you for the video...It will save me from crashing my birds. Your vid's are really helpful!

Thank you very much !!!

Very cool. Awesome tutorial.

Thanks brother! I just subscribed. 👍😊

Thank you very much, very clear and easy to understand.

Great explanation, it helped a lot!

Hi ray,I have here dx6i tx in 200 size heli w/ 3500kv motor,120t main gear and 12t pinion,what throtle & pitch do you advise for set up?

how does it apply to quadcopter? I heard Charpu(a famous guy in quad racing) said that he set his expo at 65. Can you explain it to me in a quadcopter view. Thanks

i searched entire youtube for this explanation thx alot

Excellent explination. You made is very easy to understand.

Thanks dude. Just starting out and this video helped immensely 👍👍👍👍

Great explanation. Thanks!

Excellent job thanks for making it.......

Good job ..DR and EXPO made EASY Thanks Ray

Excellent explanation! Now I get it!!!!

Great video... but I got a little confused! on my skyfly control and on Clear view flight sim, negative numbers in expo make it less sensitive in the middle not positive numbers? any idea why?

great teacher, thank you so much sir

I had one of these radios in 2007 in Australia when they first came out. They had a receiver. Think it was an AR 6000 or something. It had a satellite receiver. I had brownout issues and a few crashes since then I’ve gone futaba had no issues.

great explanation sir . thanks

Awesome video, really helped me understand what dual rate and expo does. Even though I am learning to fly planes I suspect the concept is the same?

Thanks it's the best explanation

great explanation!

learned a lot good video Thanks

THANX simple and to the point

Hi rey after I followed all your video setting up tx to heli,from mcpx to trex 450,wow it helps me a lot big thanks!!!last saturday I flowned my 450 several tyms my battery puff up and it doesn't went back to the same size,do I need to dispose it?iam using turnigy 2200mah 3s 20-30c.what battery do u recomend w/ longer flight time.tnx...

Hi Ray. Good Video again. I have a question: could you use a 2 cell 800 mah from a CX2 on the 120 SR Without burning out the main circuit board or motors ?? The CG and weight could be a problem I guess. Thanks for subscribing.

Thank you a very easy to understand explanation!

Nicely explained and very clear to understand. Thanks very much for this video.

You really helped me out Thank you

it depends on your flying style are you going to do basic flying or acrobatic .you can try the ones i put out in a video for my trex 450 pro they should work pretty good search my channel for align trex 450 pro throttle curves

Thanks bro!

great help!

Very helpful. Now, how do we change those settings within the DX9?

Thank you!

good job

im here to help

I would use a thunder power g-8 70 c 2250 mah lipo . great battery

thank you so much your video helped a lot

I have an RC car that can go 70mph with 30/87 gearing and have an LCD transmitter and 5ch receiver. Carson electronics pro 2 I think

Hi, yes, many newer radios, XK, Radiomaster, Futaba and many more use Negative values to decrease the exponential, so the rest of the video is fine but beware and check your radio first.

thanks!!

excellent session and really very very constructive please keep it up and prepare one about subtrims adjustment

thank you

Thanks that helped a lot

i would use a protek battery and i would use the one it calls for

the 120 sr uses a 1 cell pack so a 2cell wouldnt work

jeesh...i have rates at +40 for all 3...sooo...now im a "dummy" nice...thanks for the insight my friend...smh

If I had a dollar for everyone that doesnt use it because they DO NOT understand HOW to use it. I like to set my duel rates to make it EASIER to Fly my planes and helicopter. Those that just dont get it should get their plane , set it up and leave the setting program open so you can SEE what the rates DO.

I agree good job I have a better idea of what they mean thanks

Most confusion could be cleared up if better names were used for these settings, dual rate and expo mean nothing to beginners.
