Dual rate and expo ,understanding how they work 

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

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

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

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!

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...

Thanks it's the best explanation

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.

Thanks bro!

Thank you!

great help!

You really helped me out Thank you

good job

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

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, 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.

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?

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?

thanks!!

im here to help

thank you so much your video helped a lot

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

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

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 that helped a lot

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

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

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?

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

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 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

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

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

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.

Thank you very much!!!

Awesome thanks!!!!
