Throttle Lock for Radiomaster Boxer with EdgeTX: My NEW FAVORITE!

There are so many different ways to setup a throttle lock on EdgeTX, the only real limit is your imagination. In this video, I'll show you a relatively simple but highly effective and SAFE throttle lock for your Radiomaster Boxer running EdgeTX. Of course this logic will also work on color radios like the TX16s as well. Thanks to PCBWay for sponsoring this video.

There is a huge community out there now small screen edge tx transmitters. Keep the tutorials coming with the smaller radios, highly helpful 💪

[@RCVideoReviews]

Appreciate the feedback. Thanks.

[@MichaelRogersJesusrules]

As a beginner and mid aged , Im amazed every time i watch your videos ! Gods blessed you with some awesome talents, thank you for sharing ,im sure i will use a lot of your instructions as i learn how to fly,build,programme,etc ! big thanx mate

[@RCVideoReviews]

One of the best things about KZbin is its ability to bring like minded interests together. Glad my content is useful for you...and thanks for the kind comment.

[@elisrcadventure]

wow, this tutorial video indeed helped me. i just bought a boxer and still figuring out its settings. looking forward for more videos for boxer radio. thank you

[@RCVideoReviews]

Glad it helped!

[@williamcox3852]

It doesn't take you long to figure out a arm-disarm switch when the model on the table suddenly becomes airborne. 😄 Great video John.

[@PockoRC]

wouldn't happen if you took the prop off😉

[@RCVideoReviews]

I think the beauty of EdgeTX as being discussed in these comments is there's always some way to do things that works for the individual, and that's the key point.

[@PockoRC]

@RC Video Reviews since setting a throttle cut up (which I've done loads) and accidentally hitting the +/- and not realising, model on the bench went full throttle when I flicked the switch. luckily no damage to the model and I was behind it at the time. I'll never set up a model with the prop on again. I got luck. others have not.

[@RCVideoReviews]

Yeah, you gotta do what works for you.

[@PockoRC]

@RC Video Reviews I use throttle cut but for the initial set up on the bench prop comes off while everything gets tested

[@bulufish8208]

This community will grow if we have more instructors 👍 like u. And not like some always saying the truth is on this channel. Thank you for your time and effort 👌.

[@RCVideoReviews]

[@MammothPaige]

I love my Boxer, it's a great value.

[@RCVideoReviews]

Yes they are. Amazing radio for the money.

[@Drones_Eye_View]

Thanks!!! This is great. I'd like to do another switch for "emergency" throttle off too. The more Boxer videos, the better. :D

[@RCVideoReviews]

"emergency" throttle off is basically what a throttle cut does. Just lookup any throttle cut video I have on the channel (there are several). Logically speaking: Use a switch to override throttle channel to -100.

[@zebzeb3219]

I happened to accidentally kill my motor twice during flight by touching the wrong switch...That's a great improvement to your already-good previous throttle lock, thank you John.

[@RCVideoReviews]

[@vavanetsp]

Perfect. Thank you for sharing the knowledge.

[@RCVideoReviews]

You're welcome. Glad to help.

[@PopeyeFPV]

Hey this was pretty cool and this makes good sense as well! While we're talking about throttle, I think all that could be needed or desired would be a reverse thrust option for landing. Some planes are heavier than others, as well its cool to stop any plane a lot faster with a reverse thrust feature. I really appreciate your content and have learned A TON from you. Thank you for all the knowledge provided, it has helped me more than you know. 👍

[@roystevenson9632]

Outstanding again, thanks. I recently got a Boxer 4 in 1 for my son and I to use with UMX BNF products. Although not a complete noob to RC, I kept things simple with my DJI controller with air units and vistas in my drones. There is a lot to figure out with binding, as some controls are reversed etc, but there are some older video’s covering this with a TX16. Just a suggestion, as I think the Boxer will become very popular, maybe a full tutorial on your setup with something like A Turbo Timber Evolution basic ( as this is one of the models I have!) would be beneficial. Thanks again.

[@RCVideoReviews]

Glad to help. Thanks for the suggestion.

[@wingsounds13]

Yet another way to do a throttle lock. Interesting that you choose to enable lock only when the throttle is down. I use a different scheme that will only unlock throttle when enable is selected and the stick is down, but throttle off lock will enable with the switch regardless of the throttle position. I see points for both ways, I'm just accustomed to throttle off lock NOW! No chance of failing to lock because the stick wasn't all the way down. Then again, there is the chance of accidentally killing the throttle mid flight. Easy enough to re-enable if you don't panic and forget how. I use my throttle lock on my boats too, on a three position switch: lock, forward enable, reverse enable. This way the throttle stick works full range forward and reverse and forward/reverse switching only happens when the stick is at full stop so you can't slam that poor drive system from forward to reverse at high power.

[@RCVideoReviews]

The real point is to show the logic. People can and should adapt to their specific needs as is the case with about every logic video I make.

[@wingsounds13]

Yes, I get that part. This is one of the amazing and sometimes frustrating parts of OpenTX/EdgeTX, there are usually many ways to achieve the same goal. Yes, I found your video and your solution interesting.

[@RCVideoReviews]

I try and encourage people to do what works for them. To your point, there are many ways to complete a task.

[@53roger]

Thanks for the info.👍 As presented here: i view this just as ANOTHER way to setup arming on your RC, its not the only way. In nearly 45+ years of flying I have never accidently hit the disarm switch while flying (if you have maybe you need to consider if the switch is in the wrong place) or maybe that 1 time was a freak occurence. But lets think this through logically, on a plane, who cares if the motor shuts down (unless you are really close to the ground), just re-arm raise the throttle and move on, ever heard of gliding or dead stick landing??? On a quad its a little different...if the disarm switch is triggered it takes a second or 2 to get the flight controller to allow arming while you are watching your favorite flyer plunge toward the ground at break neck speed. Putting the switch where it is unlikely to be hit during flight would be the most prudent thing to do. But I guess that won't happen because the majority of RC flyers are old farts (me included) that are too old, stubborn, not tech savvy enough to be willing to make a change. So for me i want my disarm switch to disarm NOW, not after i also remember to lower the throttle. Another post mentioned to have a voice prompt 'Disarmed' or "Motors off" (which i have) to warn us when we do the unthinkable. 😁 Happy flying

[@RCVideoReviews]

Would be simple enough to remove the and condition from disarm logical switch if you want disarm to occur regardless of the stick position. That's the beauty of this EdgeTX--unrivaled flexibility to make it work the way you need it to work.

[@davidhogue100]

@@RCVideoReviews What would you set the and to in that case? I want the switch to disarm no matter what the throttle position is and only re-arm once throttle has been to zero

Thanks!

@@RCVideoReviews The radiomaster Boxer (4 in 1), is the first fixed wing radio I have purchased. I am hoping to get out this weekend for the fitst time flight. I have been using a flight simulator for about two months. I still need to bin watch about 2 hours of your videos, and I should be ready to fly Sunday. So far i really like the boxer. Again thanks for all the useful videos. Keep up the good work.

[@syros218]

I have a boxer but this is too difficult for me. I activate the throttle with the SE switch. Thank you for the video.

[@dronepilot260rc]

I do Throttle lock on all of my models with Radiomaster TX16S. Had a few accidents before that nothing serious lol

[@RCVideoReviews]

Good choice. I have some form of throttle lock on everything I fly too.

[@kevingearhardt5208]

Thanks for the video! I just went through the setup on my new Boxer radio, and it seems to be working as shown in your video. However when I flip the arm switch with the throttle up, the motors on my quad are still arming even thought the radio shows it's not armed. Am I just missing something simple? FYI I'm a total noob with iNav and my Speedybee F7 V3 flight stack.

[@pfeerick]

I use a slightly more complicated LS, but this is certainly a nice understandable one I'd like to see more people using. I prefer that if the arm/throttle enable is set, it can only be actioned on if the throttle was in the down position at the time of pressing the arm/throttle enable position, not for it to be able to arm just by pulling the switch down. i.e. if the throttle was not down at the time of pressing the switch, you have to pull it down, and then unset and set the switch again before arming occurs. And, if the disarm state is pending, with the throttle still up, I have it so the transmitter beeps to warn/remind me of that, so I know the throttle will be cut if the stick goes below -98. It's somewhat loosely based on the logic from Mr D's Open TX Ultimate Arm Switch, and I think ends up at 6 LS for the arm/disarm logic, and a 7th LS for the disarm pending check. Then there is just an extra Play Sound SF.

[@RCVideoReviews]

And that's the overall beauty of EdgeTX. These videos are meant to show techniques that can be assembled or used in ways that meet the needs of the individual. You know what I say: "Your money, your hobby". You have to make it right for you.

[@JustKeepLivingFPV]

You could program the momentary switch to copy all inputs? So im flying and want to keep doing a certain maneuver hold sf?

[@ciobanurivelino3844]

That one i'm using for many many years. About 10.

[@RCVideoReviews]

It's a very good setup.

[@geeves21312]

You do absolutely fantastic tutorials! Thank you. Wondering if it's usual for wanting some kind of criteria (such as min-throttle) for disarm? I viewed disarm as a way to kill the model in case of emergency, as well as to keep it safe before takeoff. Is this not always the case?

[@RCVideoReviews]

Hello and thank you for the great tutorials. Im used to use S1 for Arming switch. Am trying to configure this on Logical Switches but i cant find S1. Any suggestions ?

Ask for the pots to be added to the logical switch options. The 6p switch is and I believe it's considered a pot. You'll need to make a feature request here: github.com/EdgeTX/edgetx/issues/new/choose

This is a question for discord where you can show your configuration. I can't envision how you're setup so can't respond to the question.

[@BigWillieFPV]

Another great video 👍🏻My arm switch has always been SE, how do I go about doing this with 3 position switch? Thank you

[@RCVideoReviews]

Use the exclamation on your active switch which means NOT that position. For example, if I wanted SE up to be armed, and SE mid or down to be disarmed: !SEup = Override Chx -yyy That line is ignored when SE is up. It is active when SE is NOT up. (!)

[@BigWillieFPV]

@@RCVideoReviewsgreat thank you I appreciate you help 👍🏻

[@doublediamondrailroad5949]

What if I use Spring Centered Throttle? Work the same by pulling Stick Down to Stop, Hold it, then press Lock Switch. OR select Lock Switch first then pull Throttle Down! Only difference is i guess Throttle always in Middle by Default for running Drones or RTF Helis?

Try it...see what happens.

Logical switch order is not material in logic definitions. I skip lines to show groupings of events for videos.

[@cj910]

Hey Mate, gerat video! It looks like you are flying only, but maybe you can help us MT12 users. We try to figure out a cruise control, that works like on traxxas. The Idea is to have a switch locking the current speed... speeding up should be still possible by using the trigger and only breaking turns it off. And a poti should overwrite ch1 (or ch2) while its beeing locked so you can change the speed stepless🤔 Second idea I have is, that the Poti is set to center (0) and as soon it turns greater than 0 (so x >0) it should overwrite Ch1 (or Ch2), so the poti AND the pullingtrigger can take control about CH1 (or CH2) but the Poti only than, if the value is greater 0... What do you think about this ?

[@RCVideoReviews]

Maybe start with this: kzbin.info/www/bejne/n2WpdJ13lLtnn6M and sprinkle in a little of this kzbin.info/www/bejne/jaGmc5iFgbmjbZo

​@@RCVideoReviews haha I made it! I just Setup a second mixed value for Ch2, controlled by the Poti and a Max weight of 30 (because 30% for crawling is enough) and it worked just fine! 😊

[@RCVideoReviews]

Nice job!

[@Poundy]

yeh that one is pretty good until you lower throttle below the limit, and try to apply power 🤣 In all honesty, there are so many ways to skin this cat, it's hard to think any of them are "best" practice.... so I am OK with my current approach (one of your earlier ones) as meeting my needs, but i appreciate the added capability this does have. What i REALLY like about these vids though is how it can open your eyes tot he "simple" things you can use to build complex things. As a newbie I am sure there's lots of things I could do when I find a need, and I have the tools to start that learning and development...

[@RCVideoReviews]

You can move the throttle from 0 to 100 with the arm switch in the armed position. It only cuts if you disarm, then lower the throttle to zero. But you've caught the spirit of the video which is to show logic in use to give you ideas on creating your own solutions.

[@Poundy]

@@RCVideoReviews yeah i knew what it was possible to do - I just wanted to point out the "trap" that you could get into but hey, you disarmed it deliberately, a quick switch flip to get your throttle back is easy if you needed to. Absolutely these vids are excellent resources - someone can use it as their "true" solution if they want since you've given all the components, but again it adds to the building blocks that others have in their arsenal to build what they need

[@BooDevil65]

Thanks, cool stuff! But what happens if you bump your switch unknowingly ... then later happen to go to zero throttle to glide ... then when you go to throttle up out of danger, *nothing* ... seems potentially dangerous ...

[@RCVideoReviews]

There's **ALWAYS** **ALWAYS** a "but what if" when it comes to throttle locks. If something doesn't suit you, don't use it. In this case, it would take two mistakes in a row by the pilot to cause the situation you described. I would argue if the pilot is that careless with the controls on the radio, they shouldn't be flying. It's literally impossible to write throttle lock logic to please 100% of the people who watch these videos.

[@BooDevil65]

@@RCVideoReviews Of course - I write software for a living, and everything is a compromise. One could just as easily argue that someone who doesn't check their throttle every time shouldn't be flying either. My question was more from a "which situation do you think more likely with planes" standpoint - I'm a quad pilot just getting into planes, and i have never armed with the throttle above zero in my 8ish years of flying quads.

[@RCVideoReviews]

The basic throttle lock is a simple override. It's a one line config. Unfortunately, "bumping" the switch can cause an unintentional launch. I encourage people to consider the logic and adapt to suit. For me, I think it's a very very good idea to ensure the throttle stick is at its lowest position before arming. I've personally never made the mistake of disarming a model while flying it, but this method offers a 2nd chance in the event someone does.

[@marksherman630]

@@BooDevil65 I'm in about the same place as you - 7 years of building and flying quads, and just moving into planes. A quad using Betaflight on the FC cannot arm with the Thr above the min value. This is programmed into the BF firmware.There are other reasons for not being able to arm (like being connected to the BF configurator - remember you have to disable the FC on the motors tab to be able to test motor response). But the main error code we all get is for not having Thr all the way down. You don't have to set anything up on your quad for that. You do have to assign the arm mode to a channel and an input (usually a switch). On planes arming is not automatically prevented if the Thr is high, so they need to specify under what conditions the Thr channel is on and when it is not (Thr cut) via the Logic and Special Functions tabs in the model. I'm with jp7361 below when he says he prefers the Thr disarm to work no matter where the Thr is. It's probably because we drone flyers tend to fly lower and around obstacles, so a lot of our crashes happen with little to no warning, and you want to get the props stopped immediately before they cause a lot of damage tearing your quad apart on the ground.

[@malte9999]

You can add a voice prompt for (pre) arm/(pre) disarm so know when you hit it accidentally
