How to trim your fixed wing model all at once using OpenTX Instant trim

[@lorenzomacchietti9102]

Incredibly useful function. I get always surprised by how many tools taranis and openTX have!

[@mikekindon3923]

I don't know how you stumble upon these things, but im sure glad you do! all the best from NZ to you and yours.

[@timtheplaneman]

KZbin needs a "Wow" like for things like this.

[@jayfpv9376]

Wow! Thanks Lee. How many times have I trimmed a new plane hoping I wouldn't crash it in the process. That's great!!

[@dos4gwexe]

I recently used this for the first time on the Tango 2. It's basically required on that transmitter, as it doesn't have trim tabs. Once you get the aircraft flying more or less true, you can trim it out using the T2's jog wheel trim. It worked even better than I had hoped! With this feature, the T2 becomes a viable controller for flying fixed wings.

[@438fpv]

May I ask what you mean by jog wheel trim? I'm looking into fixed wings on the T2. But no trims kind of put me off. With the jog wheel trim, and the instatrim, I guess I need to buy a wing now 😌

[@dos4gwexe]

@@438fpv if you double press on the jog wheel, you can step through the different axes and then trim them by turning the jog wheel. It's cumbersome, but with the instant trim it works well enough. See this video at 3:15 for a more thorough explanation: kzbin.info/www/bejne/r5yxqJhmgbWUjZY&ab_channel=Painless360

OMG as many have already said. I never knew this was a feature. Thanks for posting and bringing to are attention.

[@skypilot23]

really nice to visit Painless 360 one remaining bastion after all the world's implosion

[@alex8527-w1q]

"one remaining bastion after all the world's implosion" You are so right. Thats why when I feel the urge to watch the news, I go back to building or flying RC. The ultimate stress reliever. Well, that and sex.

[@skypilot23]

@@alex8527-w1q feeling so very irritated with this veil of tears if not for my escapism I dunno (and my cat) fly every chance I get break things just to have a project it's nice to hear from a kindred soul usually it's not sexy girls addicted to RC though! lol

[@kwaaaa]

This is truly one of those under-the-radar features. I literally learned about this few months ago and it blew my mind that it's been around. Even many seasoned OpenTX pilots were unaware of.

[@upperechelon3456]

Excellent video [as usual]. This is a very useful, under the radar, and powerful feature. I use it to trim my planes in manual setting without interfering with the flight controller functions. The trim to sub trim feature that re-centers everything is a godsend.

[@RickMaddoxSr]

Well DANG. Why did I not know about this already? That will be a new feature I use a LOT. Thanks Lee.

[@rrenegadoo]

😱😳Whyyyyy😟😟..... I just did yesterday the maiden fly of my new✈ 70 mm EDF 🦇Vampire 🇨🇦Canadian Edition 🇨🇦 and really strangle with the trims, finally I managed to make it fly on rails. But definitely I'll use this fantastic option next time.... tank you for sharing all your knowledge and experience... 👌👍... greetings from Colombia 🇨🇴

[@z2kk]

Looks very useful. What happens if you use Instant Trim a second time in the same flight? Does it stomp the previous trims or add to them? Edit: I just tried it out and it adds stick positions to current trim values, so no stomping.

[@michaelmccarroll4202]

OMG I wish I had known about this long ago. Thanks Lee

[@100SteveB]

I have often seen this in the special function menu without even thinking about what it was for! Very handy indeed, thanks for pointing it out. But I must add that if my plane is too far out of trim I always prefer to land it and make physical adjustments to the control linkages. But, for those flight where you may have got the battery position slightly off, or something else is knocking the trim out I think i will be using the instant trim in future, looks so much easier than trying push the trim tabs individually. So great video, a very useful tip indeed - thanks!

[@MCsCreations]

Oh, that's fantastic! 😃 Thanks a lot, Lee! I'm definitely going to use it! Stay safe there with your family! 🖖😊

[@rydfree]

I use the DIY button mod on the back left side of the RadioMaster TX16 for this. It is in the perfect position to press without inadvertently moving the sticks.

[@Painless360]

Agreed! I've found my trigger mod installed for FPV. Combat perfect too... Happy flying!

[@urlawyer]

I like to get a good mechanical trim, so once I’ve dialed in the tx trim settings appropriately, I will land the aircraft, note the position of the control surfaces, zero out the tx trim and adjust the servo rods so that they hold the surfaces in the adjusted position with zero stick input/trim. That maximizes your range of control and your tx/FC resolution.

[@Painless360]

That is the ideal way to do it. I've covered setup in many of my videos (i.e kzbin.info/www/bejne/a2TNk4mZgKaHpMU) but it usually takes a bad experience from a pilot (or a more experienced one taking them through it at the field) that makes it stick. Happy flying!

[@matthewallen3375]

I Can't believe it is THAT simple! where have I been, and how did I think it was so hard? Thank you.

[@stephanreef8449]

Fantastic. Again a very usefull tip. Thanx painless 👍

[@jlarson42]

Very informative and helpful video. Thanks for sharing. 🤓

[@sparrow082]

That is a very useful tip. Thank you.

[@rougeneon1997]

Thats nifty. I didnt even know that was an option in OpenTX. Isn't it usually "frowned upon" using the tx to trim a plane a significant amount rather than fixing the model? I can definitely see that being used on a maiden just to keep it in the air essentially until you land. I do realize this CAN NOT be used with iNav like any radio trimming.

[@Painless360]

Some pilots get very sniffy about too much trim. That assumes that the model has been buult and setup perfectly to start with and has the nessessary roll bias to take care of the torque roll and the right amount of reflex from the elevator to keep the nose up. This is why I cover control position and throws in my videos as its a guessing game for a lot of the foamie models. Some of the 'instructions' for some models are laughable. happy flying!

[@rougeneon1997]

@@Painless360 I completely agree. I guess in watching your vids I usually "Take" them as a stand alone informative video. Do you own a "Nano Goblin"? Ive heard the shipping for them to the U.K usually out-weighs getting one. Its my FAVORITE flying thing. I think every fixed wing flyer should experience one. 😎

[@adamhale6672]

Occasionally I maiden an aircraft that (horrifically) requires more than the transmitter will allow me to trim out. I presume that the instant trim command maxes out as well, correct? Thanks for showing this useful tip Lee! I’m throwing it on my transmitter right now.

[@apachesmokemachining6487]

That was really useful, thanks

[@SonAndDadFPV]

Never new this existed 👍

[@its_Savian]

hi can you please make a video 1.2ghz video transmitter vs the 5.8ghz transmitter

[@Painless360]

I don't use 1.2 here but I have made a few videos that talk about it. See my videos on flying further i.e. kzbin.info/www/bejne/jp_HpphmbrJgoqs

[@jps99]

Wow, thanks for that awesome tip!

[@davidknox294]

nice one Lee....i had seen reference to insta trim before but thought it might be hard to set up ,so stuck with the land and manual trim method (noob pilot)lol. does this have to be set per model ..or could it be set as a global function ? i do like the set trim as subtrim too ...another function i wanted to try but never got around to ....

[@Painless360]

I set it for each model flown without a flight controller or stabiliser. It takes seconds to setup. Best of luck

[@sparkey044]

How about 5 clicks of up elevator on a switch, then after launch switch off to 0 trim, such as launching a wing. Have a video on this?

[@Painless360]

Lots of videos on the channel about that. I.e. kzbin.info/www/bejne/injIgK2EhbeUgKM

[@maxun1]

Is a nice feature but in the same time can bite you big time, specially if you are a beginner pilot, just be careful, looks nice, is not. A small bump during the switch activation or a dynamic movement from the radio and you fingers and you going down fast really fast.

[@Painless360]

Agreed. I find this very handy for models that come with poor setup instructions so you end up with a lot of pitch adjustment to just fly level. Frustratingly, then cant take your fingers off the control to trim in without the thing nosing into a fatal dive.. happy flying!

[@maxun1]

@@Painless360 100% Correct Lee, when I go up and plane is all wacky, specially other people planes in maiden, that always they said can you flight it first? The plane goes, nose down and then violent left or right and even out of balance, so I do one at the time in medium speed, first ailerons, then elevator and done. I make sure I got extended trims in the radio.

[@StevePotter]

I think it would be better to put this on a left hand switch so you can fly precisely while hitting the switch. What do you think?

[@Painless360]

You can use any switch for that you want. That is the beauty of OpenTX. My radio has a mod that makes it even better - kzbin.info/www/bejne/l17Ken6nmrt_r5Y

Great info 👍🍻😉
