Throttle scaling is a Betaflight and OpenTX feature that lets you tame over-powered quads like some 2S tiny whoop. But the feature works on any quad! I'll show you two methods to do it, one in the Betaflight Command Line, and one in OpenTX.

It turns out that you CAN switch the betaflight throttle limit on a switch. CurryKitten shows how here: th-cam.com/video/rwUdwUMMytI/w-d-xo.html
Use throttle_limit_percent>9000 to go really fast
Yoshitake Mizuno says: !SC-UP , use this to work around the 3rd low position affecting the throttle in a unwanted way.
You can use Sitcks commands too, left stick to left bottom and right stick left middle is profile 1 I think
when you have to do terminal commands, can you type /paste them into the description so we can copy/paste ?
What's solution for this

With all due respect Josh you are my favorite nerd.
This video saved my hopes of being able to hover my quad after destroying it on the first ever flight, now set to to just 15% throttle power, hovering like Magneto and new frame on the way. Keep up the good work.
I can't explain how precious your videos are for me as a beginner! Thank you so much.
This is EXACTLY what I was wanting to do. And you explained it so clearly and walked me right through it. THANK YOU!!!!!!
I would never have managed to get my first quad build airborn without your helpful videos and after losing it three times I now hope to be able to keep it. Many thanks.
Thanks for always working to make our flying life easier Joshua. Truly appreciated
Can’t thank you enough, just did this to my whoop and now I can actually fly it!
I make outdoor/indoor shots and I looked for a way to fast change throttle power. And this is it. Thank you!
Great Sienfield impression! Love it!
So cool! I add this switch and love it! Thank you JB
I wanted to setup my US65 to let some newby’s try it out.
I remembered seeing this video a while back and found it.
Using the switch is perfect for keeping novices out of trouble.
I also setup another PID and Rate profile to tame it.
As always...thanks for the knowledge.
Thanks for your help yet again...
Awesome video. I just now (barely) mastered what you taught and now I'm working on variable authority using the sliders. I've managed to get pitch/roll to be less/more effective with one slider by multiplying them in the mixer, but I am having a devil of a time using the other slider to give variable throttle authority. Keep up the good work!
Finally!!! First time I was able to have some semblance of control on my Mobula6!!! Was able to use your info on BF 4.3 GUI. Now, to charge all my little batteries and practice!!! Thanks!!!!
Your videos are a major help to a newbie like me brother. Thank you!
Thank you! This is exactly what the community needs!
I like using a custom curve tuned to each model, this allows me a fast ramp up to hover, a nice long slow ramp through the mid throttle then another fast/steep ramp up when I want balls-out.
Love your show, it helps us out so much!
Thanks Joshua, you are an excellent teacher! I have learned so much from watching your content, thank you!
Your videos is the best! I learned betaflight and how to assemble a quad from pieces, tune it and fly. Thanks, keep up the good work!
Wow Bardwell best teacher in this hobby. Thanks!
Thanks Joshua!!
I mostly fly my mobula in my small apartment, without throttle scaling, without any problems and I've only been flying for a few months. It has definitely helped my throttle management. And I don't have to mess with betaflight. Then when I want to fly it outside I just take it out there and open it up.
i love finding out new things about the taranis series. just makes the value of the x7 (even the x7s which i bought) so much more, compared to simple radios of the past. so many ways to customize it it's crazy.
Absolutely fascinating!
Absolutely brilliant video for FPV learners (like me). Having flown 700 Helicopters 3D its a whole new learning curve. JB (Joshua Bardwell) is the FPV Drone master. Sit, Watch and Learn.
im learning with my 5 inch quad and this is just the thing i needed. awesome video you always got the answers
Thank you!!! I was crashing into everything in my home with the Tinyhawk, scaled it down to 65, perfect for indoor flying (50% wouldn't take off 😂)
Hello JB
Have learnt something today again. Easy to follow and it works. Fantastic video and it works, thank you
regards
Jon
Thank you sir....cant wait to try
Dude, after years of camera drives, I just started the FPV hobby. I've watched dozens of your videos, but this one changed my life. I have a Tinyhawk II FS and a TX12. It used to ZOOM straight up on the tiniest bit of throttle. It is definitely more SANE now. Thanks a bunch!
PS the TX12 is the deal of the century and #BuddyRC rocks.
how :(😪
Thank you for the clear info!!!!!
Always loved graphing calculators
JB perfect timing for my 5s & 6s Mid KV build :)
Super helpful. Thank for your knowledge 👍
Thank you Josh, really helped me when learning to fpv. Good video
Great video. You cracked yourself up at the end with that Seinfeld inspired rant.
Serenity now!
Thanks! This is very helpful. I am learning FPV with a Freestyle 2 but the only place I have to fly is in the yard and there is not a lot of room and a ton of trees. When you don't have much space, a little power seems like a lot of power. When I fly at work after the workday is over there are big fields with small trees spaced out nicely. Full power is great. At home though, I'm running 1s to slow things down but I am still sometimes finding myself looking down on trees when I didn't think I had given it that much throttle.
Awesome, that saves me buying 3s batteries during my learning curve :) Thanks!
This really helped me alot..thank you JB
@Joshua Bardwell
I have been doing something similar for about 6 months now. I setup my throttle so that most of the range is very low, but the the very top of the throttle stick [>98%] jumps to full throttle. In other words, I have 0-75% throttle linear, and then 100% at the very top. So, for example, I cannot command 90% throttle.
I really like this because on my 6s quad, anything over 75% throttle is just ludicrous speed anyway. I did this with my spektrum transmitter rate adjust that lets you set points on a linear graph. I made a negative linear throttle curve for the whole range except chopped it back to normal at the very top.
The man has spoken
So helpful thank you!
love this trick
Brilliant!
Amazing this and your other videos are so helpful and make it so simple for 'beginners' to understand the concept, you know 'teach a man to fish as opposed to give a man a fish' ... ...... kind of way!! Learnt a lot from JC of project Blue Falcon on using Taranis and I continue to learn from you. Thanks for making this hobby enjoyable !!!
I use the openTX method on the same switch as my flip over after crash, that way my throttle is limited to whatever percentage I want but when I switch to flip over after crash, betaflight is reading a 100% throttle to flip and not my limited amount. That extra amount of power to flip is especially helpful with whoops.
I know this is old, but I'm glad I found it, I'm such a noob and have no control over this beast yet, I can actually control my sector 123 better (trust me that's not saying much) but I do need training wheels. Thank you for this video Joshua
That was the best outro ever!
Always enjoy your videos, always learning!! :)
Great I just built my Tyro99 You and others are great and a big help. Greetings from New Zealand. We have a few know it all renigages that will destroy it for us all here.
Great impersonation at the end Josh. I had to replay it a few times and still got a smile.
Well explained. Thank you.
WOW ! Great video Josh
Hey Josh, hilarious ending mate :)
i cant believe how easy this is....i love open tx and i love your videos... thanks a ton man
Check the 1st comment for a correction.
Yessir. Much appreciated on the reply... it tamed my trashcan right down
Well explained Video, I appreciate it. Happy New Year to Everyone,
This is pretty cool. I might put this and lower rates on my switch for trainer mode when I'm buddy boxing learners.
Then I can fly back and land or otherwise rescue them, but still using rates and throttle I'm used to.
Thanks!
Really helpful...as usual!
This is very helpful, Thankyou. I'm a patreon and it's so worth it... AND love the Steinfeld impression :) too good
Ahha, I did learn something today! Thanks Joshua
So darn useful! Exactly What I needed. Thank you
Make sure to read the first comment pinned to the top of the comments section here.
Thanks, Jerry:-)
Being a complete new, this is fantastic!! Thank you!!
That towel, lol
This hobby really is in sync with itself, CurryKitten uploaded a video about 9 hours ago talking about how to tame the Mobula7 using Betaflight throttle limiting. :)
Lmao I just said that 1 minute ago...look above...
It seems like these guys follow what the others do
Except CurryKitten has a great solution to being able to switch between indoor & outdoor throttle limiting - simply setup different Rateprofile's so you can use a switch on your TX to go between the two, without having to go back to Betaflight.
@@licensetodrive9930 lol...joshua responded to me.... (wait until part 2 video)...
Good Point. It's great too since you get a lot of great solutions, variations, and the overlap helps reinforce what you decide what's the most common solution, simplest or best.
I remembered the most simple way of switching between Rateprofiles; by using Stick Commands.
There's literally nothing else to setup on your TX or Betaflight beyond a 2nd Rateprofile for the lower throttle.
edit: Scratch that, Joshua pointed out it changes PID profiles not Rate profiles.
Thank you! I learned something today. Time to buy some more stuff form you affiliate links.
I do the TX change via a mix instead of inputs and use a pot to change the amount. This way I dial up the throttle as required.
With this I can test hover a very powerful quad in a small area with almost no chance of a runaway. I set the power so low it barely hovers on max throttle.
The mix is:
CHx:IThr Weight(100%)
*= S1 Weight(50%) Offset 50%
+= S1 Weight(50%) Offset -50%
What this does is it changes S1 into a percentage (0-100) and multiplies the throttle by that scale. The next part uses the same S1 percentage to lower the min throttle so the base is always -100.
I also remove trim from my throttle (so that the any bump to the trims does not change throttle output). Quad's never need trims.
I came up with a way to do it using global functions and the input line, but it was hella complicated. Your way is far simpler.
@@JoshuaBardwell Thank you for the credit and mention on the Throttle Limit on Side Slider video. - th-cam.com/video/m9Gf95fapoQ/w-d-xo.html
Great video as always... I'd like to point out you can do that on many Tx's and set to a switch also..... I'd also like to point out another way I like anyways is to go into Betaflight/ pid tuning/ Throttle expo.... I'm running at .20 expo.... now I can keep it level a lot easier doing 90 around the house without bouncing it off the ceiling and still have full power.. lol... keep up the good work!
nice info...thanks
Hey Joshua, great minds thinking a like and all that, I did a video about this very subject earlier today - gives me confidence that I was on the right lines if you're talking about it as well :) Some people may have already mentioned it, but as throttle_limit stuff is part of the rateprofile, so it's easy to switch different throttle limits around this way. You could use the adjustment tab, but in my example (I was using the X-Lite and had run out of switches) I simply used the Betaflight OSD to switch rateprofiles - so very easy to move your limits for inside/outside (in the case of the Mobula7 at least)
The easiest way to switch between Rateprofiles is by using Stick Commands - don't need to go into the Betaflight OSD or setup a switch on your TX & corresponding Betaflight setting.
github.com/martinbudden/betaflight/blob/master/docs/Controls.md
Only watched this as I thought he was going to give you a shout mate. Right lines indeed.....
Hey CurryKitten. Kudos on the comprehensive video. I didn't realize it was tied to rateprofile and could be switched. I'll put a link to your video in a pinned comment.
@@licensetodrive9930 that switches PID profile, which isn't exactly the same as switching rate profile. If you have custom PIDs, then using stick commands may change you back to defaults, unless you have set PID profiles to the same custom PIDs.
Joshua, ahh nuts, didn't realise, I thought that would be the simplest solution.
Still a very good and informative video, indeed usefuld, thanks.
Yes, Joshua, there is such a thing, as I just found out on my maiden flight (GepRC Mark 4 HD GPS - my first fpv quad). :( I know you're going to show me the way. Thank you! Dang thing shot up in the air like a rocket and I got scared!
I'm new to PV, and it's weird that every time I have a question/problem, Bardwell seems to have a video about it. He's like some kind of FPVKnowItAll. :-D Thanks Joshua.
Hey Joshua, thanx for the awesome vids man, so much help for noobs like myself....;D...much appreesch...!
What I did on my Mobula7 was to simply move the throttle MID to 0.00 and then to add throttle EXPO(between 0.55 and 0.35 depending on skill level) in BetaFlight - now low throttle is nice and tame but still have full throttle on full stick deflection....so could essentially fly in and outdoors with the single throttle setting.(I don't have another switch on my DX6i to add the throttle switch the way you did) ...If all that makes sense...;P
Seinfeld impersonation thing at the end was so good 😆🤣
Mind....- blown !!
wow, this is really cool.. thanks
Thx Jerry
Reminds me of the preset modes on cheapo RTF’s we all started on
also you can change stick's Expo by S1 and S2 knobs using Global Variables
FML needed this big time 😂 thanx 👍
New dronie. Ordered a 75x 1s got a 2s. Need to turn down the throttle. Great help thanks.
I limit on my x9d with the potentiometer, 100-90-80 (full-center-min) for my FS builds. 100-85-70 on my racers. Audible call out as well :)
Do you think it’s possible to assign the throttle weight and offset to a potentiometer?
LOL @ the Jerry Seinfeld impression near the end 🤣 good one
Nice, i am waiting for my modular 7 :-)
Fantastic, JB! That should be really useful for rc planes as well!!! 😃
Thanks mate great help. Keep up the head wobble ;)
Thanks. Just in time before my mobula 2 is in the mail😜
I love you, that's all I can say haha, thanks so much for all your videos
They should add something like this to the OSD settings menu. For now, using throttle max endpoint on the Taranis is much easier and accessable in the field on the fly.
I noticed that on one of your last videos, you had the throttle at 89.
@@brandonwoodford579 I usually fluctuate between 60 and 99 on the throttle endpoint of -100 to 100 when I'm running 6S
Hahahahahah Holy ole Whoop,,Joshua! I will have to watch Your vid a few more times as i just received my Mobula2 and Taranis QX7 today. At 63 years young,,,im gona tone er down a little bit.( the whoop that is) I will take Your word for it, as this ole dog aint ever gona understand how they cram all that techy adjustable stuff into a tiny flight controller. Not to mention the complexity of rc transmitters we use to control are models, which i fear that someday i won't be able to find my way back out to the main menu. all foolishness aside,,,I want to say a BIG ThankYou for sharing Your knowledge in such a way that even i can ALMOST understand. Lol. Keep up the great work. Again,,,ThankYou Joshua! Rudy in cold Moncton NB Canada.
Thx a lot JB, my long range stuff just got a whole lot easier!
Hi Joshua, maybe this is some useful info. The throttle limit in Betaflight is assigned to a rateprofile. So if you would set up 2 or more identical rate profiles but change the throttle limits between the different profiles, then you can easily switch between the different profiles via OSD. Or if you use the "adjustments tab" in betaflight you can even put it on a switch. This is how you could easily switch between a "indoor" mode and "outdoor" mode of your quad (not only 2S whoops).
This is a great tip. I didn't realize they tied the throttle limit to the rate profile.
@@JoshuaBardwell curry kitten has the video he made on this.... this is what I ment to explain in my comment lol.... see I learn from all you guys...every TH-camr has things or says things in his video that are different (different way to do things)... so I learn from all...
@@JoshuaBardwell he made this same video 6 hours ago...(that's what I was talking about lol)... but he has stuff that you.dont and vice versa)
Josh Bardwell you sir are one of those rare cases that seem to be doing for a living exactly what you should be doing. I can only imagine doing something I love for a career and getting payed for it!. It must feel extra good to go to bed knowing that you made a positive difference in lives. I will continue to Dream a lill Dream. If there is anything I can do to contribute constructive assistance please do call on me. Im not a creeper, just a 42year old guy whom has found a calling inFPV. I WISH YOU CONTINUED SUCCESS.
for spektum on the tx in control setep you can just turn down the throttle down to to 75
Joshua is use the curve adjustment on the throttle stick.
Hi Joshua, great information for beginners.
But one thing I want to mention is, using 3-pos switch to change the throttle scale, by only using SC-UP and SC-MID, if you accidently switched to SC-DOWN your throttle output will be constant zero which means 50% throttle. This might shot your quad to the moon.
In this case I suggest to use !SC-UP instead of SC-MID, or put another 3rd scale on SC-DOWN.
Arigato Gozaimasu! That's also what I had in mind! OpenTX has a thousand ways to program stuff but a few are perfectly functional.
Hi Joshua, thanks for this video.
I was wondering if you could make an updated video using taranis qx7, because when I tried to follow and adapt this step by step I found out that the interface of the Mixer page is very different
Thanks for your excelent job 🙂👍
