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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rwUdwUMMytI.html

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!

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.

@CurryKitten 5 лет назад

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)

@licensetodrive9930 5 лет назад

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

@RogerBurgess 5 лет назад

Only watched this as I thought he was going to give you a shout mate. Right lines indeed.....

@JoshuaBardwell 5 лет назад

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.

@JoshuaBardwell 5 лет назад

@@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.

@licensetodrive9930 5 лет назад

Joshua, ahh nuts, didn't realise, I thought that would be the simplest solution.

@FPVMgunit13 5 лет назад

Lmao I just said that 1 minute ago...look above... It seems like these guys follow what the others do

@licensetodrive9930 5 лет назад

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.

@FPVMgunit13 5 лет назад

@@licensetodrive9930 lol...joshua responded to me.... (wait until part 2 video)...

@frankbarajas 5 лет назад

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.

@licensetodrive9930 5 лет назад

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.

@ArchmageAU 5 лет назад

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.

@JoshuaBardwell 5 лет назад

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.

@yoshitakamizuta2920 5 лет назад

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.

@donmichaelcorbin4417 3 года назад

@mcrubens 5 лет назад

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).

@JoshuaBardwell 5 лет назад

This is a great tip. I didn't realize they tied the throttle limit to the rate profile.

@johnwhite1103 4 года назад

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.

@CarbonGlassMan 4 года назад

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.

@davidhuber6251 5 лет назад

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.

@michaelwilkes0 5 лет назад

@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.

Can't do it. I did everything like in the video and on the channels monitor it only shows any thrust output when the switch is in the position that corresponds to the mixer source. That is I configured three inputs: th1 at 100%, th2 at 75% and th3 at 50% and the channel monitor bar only reacts to thrust movements at 100% if I set the mixer source at th1 but doesn't react to stick movements in th2 and th3 positions at all. I can change the mixer source to th2 of course and then the stick only works in th2 switch position - at 50% of course, but still it doesn't let me change anything by switching to th1 or th3. Any result of such switching is that thrust becomes dead.....
