Shrink Tubing RUINED MY TBS Crossfire Nano Rx!

In this video I’ll tell you how I ruined a TBS Crossfire Nano receiver by pressing too hard on the button. There’s a reason I was pressing too hard on it and it’s because the shrink tubing wouldn’t allow me to press it easily and in order to push through I had to press really hard… too hard. I’ll tell you how to avoid this problem by switching from the stock shrink tubing to something a lot more flexible. I’ll also let you know in what circumstances it’s actually better to used the stock shrink tubing. Finally, I’ll go in to some detail about different kinds of shrink tubing and shrink ratios.

I love the content you are pumping out. Always high quality,clear and helpful. I just want to thank Pinch for being such a great ambassador of the hobby and for all the questions, he’s patiently answered for me throughout time. I love to see good people win!

[@PinchTune]

Thank you Manny. Awesome words. Thanks for the encouragement. I'll keep them coming.

[@scarfacefpv7822]

If your button broke just peal what is left off and there will be a little strip on both sides left if you touch one of them strips with a metal screwdriver to the center it shorts it like the button did so you can still use it you just won't have the button I have a couple like that.

[@slicksix8892]

Thanks so much for this video man, great info.👍😉

[@PinchTune]

Slick Six Very welcome!

[@espenchristensen9581]

I just broken mine exacly this way an hour ago, thanks for the sdolution and answer.

[@PinchTune]

Ahh, sorry to hear. Glad I could help though. I've only messed one up thus far.

[@padillaz]

Someone made a 3D printable holder specifically for the TBS Nano Rx on thingverse.

[@mikel3419]

This is all good info and stuff a lot of folks figure out through experience. I just did the same thing to a Nano receiver. There are some pieces of guidance that says you don't need the button if the receiver has not yet been bound to a transmitter. I can't even get the lights to come on on two of them so I wonder if there is a bad batch out there.

[@PinchTune]

I've read and heard of comments like this, but so far I haven't been able to get a Nano Rx into bind mode without using the button.

[@mikel3419]

@@PinchTune I got an email back from TBS and they said that if you use a small screw driver to short the center and out part where the button came off it will work like the button. I have done this before with another brand receiver and it worked. It was tedious to do by yourself but worth a try. I did finally get one of my NANOs to bind by plugging up my Tranus and opening the TBS software. It found the receiver, performed an update and it worked. Directions from various web folks did not work for me. Don't throw out the receiver.

[@LAOhiphop]

i have always cut a tiny hole in those shink tubing to press the button

[@PinchTune]

Yeah, that's a really good idea. That button is very fragile.

[@cletussurfsalot7190]

Same.

[@divingfalconfpv4602]

I also point holes for heat over chips lol

[@SPotter1973]

Even after the foil is gone from the switch it will still work. I had one compressed by the antenna and shrink wrap which seems to have destroyed the TBS nano, which don't do what they claim.

[@smooth_ops2942]

I just double side sticky tape it to the carbon where air flow helps keep it cool for the vtx.

[@PinchTune]

Smooth_Ops I normally insulate the VTXs out of habit, even though I conformally coat. I might start skipping the tubing on some builds. But since I don’t normally kill VTXs, I haven’t been too motivated to change.

[@shaneintegra]

Air will dissipate heat a lot better than wrapping something in plastic

[@ChillerFPV]

i don't shrink tube vtx and rx, i let them free in the air, good for cooling, BUT i use Drydrone to make them water resistand. Quad whent swimming couple of times and still works just fine

[@69RocketBones]

Thanks man, you may have saved my Nano.

[@PinchTune]

Sweet. Glad to help :)

[@garethhayman]

TBS style wrap is called PCV Wrap - Search on aliexpress/ebay the 5v VTX is 18650 sized but look for AA battery sized for the smaller RX type.

[@DronemanfromNepal]

And here I an using aircraft avionics grade shrink tube ! Stole a lot from the factory ! Super thin and place nicely after a hit on the receiver

[@minkorrh]

I've heat-shrinked every Xfire nano RX I have ever used. Zero issues. Mine or their tubing.

[@divingfalconfpv4602]

I try to make them great shrink in a circle. So there's a lil gap between top and bottom. If I don't glue antenna then I will zip tie heat shrink tight on antenna.

[@leflamantrosefpv1725]

you have to make the wire of the antenna over the RX with the UFL which is over the button like that no problem with the button, despite the heat-shrinkable sleeve, as it is (even the TBS, which to my sense is the best for heat dissipation ..), and it will not go nor press the button, and the UFL being bigger, protects the whole thing, by making the wire come out to the invert on the top. on the wire outlet side. (rx tx red and black) and normally once the first time, there is no longer any need to press the button, you have to bind with the tbs software, without radio and it goes by itself ...

[@StacemanFPV]

Oooo where did you get that 3-1 and 4-1 tubing? That'd be really useful in some cases

[@PinchTune]

sᴛᴀᴄᴇʏ ABSHIRE I’ve bought it online. I’d have to look where. It’s been a while. I bought a bunch and don’t use it very often. I think the last batch I bought on ebay. Keep in mind. It’s more expensive.

[@martin19117]

Use an exacto knife after using the tbs shrink tube. Take your time when using the knife when cutting the square behind the antenna on the receiver

[@omardjperez]

@PinchTune Mine recently stopped receiving! I had the problem where i couldnt tell if it was clicked when i was trying to bind i actually bound but and fflew but now its not working any solution ?

[@maceliusfpv370]

Yeah, I've broken those. You can take them off and just short the pads when you need to use it.

[@harrum2577]

I tubed my nano RX too, it is bound with my tango 2, but the radio keeps yelling at me the 'telemetry lost' warning. Then after like 10 - 30 sec its says: telemetry recovered. And then it loses telemetry, and recovers it againg .... so on. However, I can still control (fly) the quad, everything else seems fine, green light on rx, lq 1:100, 4 signalbars ect. Could this be the possible issue? (Oh I swapped the standard antenna to an immortal-T antenna, but I can hardly believe that it would cause any issues)

[@skyrotfpv]

Great tip! I am more often in the situation to re-bind my nano rx than I wish I had to. You really have to push very hard in the tight space beween the UfL connctor and the LED light. TBS shrink tubes that ship with their nano rx are very stiff to push down on that button.

[@509FUN]

Never had an issue with the small buttons, now the large buttons on the other hand I’ve ripped off rendering it useless

[@MrGunawan79]

I ruined mine too whit that thin heat shrink tube r.i.p my brand new nano receiver

[@KickPassingShot]

What was the indicator that let you know your button was ruined, aside from not being able to feel the feedback when pushing the button down? Were you ever able to bind the receiver?

[@PinchTune]

The button got stuck, so the receiver acted like the button was being pressed constantly. Then, when I tried to do something about it, I just ended up with the button in my hand. There is a method of binding without the button. I have to do a follow up video soon.

[@KickPassingShot]

PinchTune Thanks for your reply and for not thinking my question was a dumb one. I have one nano which no matter what I do I cannot bind, so I’m trying to make sense of it. I wrap all of my receivers with the same shrink tube you use from Fry’s.

[@PinchTune]

@@KickPassingShot There are no dumb questions. Just dumb answers. I'll try to make a new follow up video this weekend. Thanks.

[@CarbonGlassMan]

My nano RX has a solid green light on it at all times, it doesn't do anything except have a solid green light on and create a lot of heat.

[@PinchTune]

Definitely sounds like the button is stuck in "contact".

[@sptrader6316]

That's the Bind button right ? Just bind the receiver first, then put shrink tubing on it.

[@mr.b6917]

That's why TBS has the agent or you just bind from your receiver so you don't have to push the button

[@DannyCruzCreations]

True, but that's these days. For the longest time Agent was only available on PC. At least it's now available for us Mac users.

[@masslona]

You probably just saved me 😅

[@PinchTune]

Good! :)

[@mrtiefpvhowtoandreview1033]

I have Broken one as well:/

[@PinchTune]

Somebody in the comments talked about a way to get it into bind mode without the button. I tried, but I couldn't get it to do it.

[@choppergirl]

Man they cut corners on the nano, that's why I hate it.

[@pavalige]

I just did the exact same thing took a flight controller with it too :(

[@PinchTune]

Ah bummer!

[@HeraklionFPV]

But why you need to press the button anymore?

[@PinchTune]

Every time you update the Firmware in the module, you have to rebind your receivers. That's when.

[@HeraklionFPV]

@@PinchTune You don't have to press the button. You can bind over the tbs agent

[@PinchTune]

@@HeraklionFPV Yeah, I've heard there are other options. I'll try TBS agent next. Keep in mind that sometimes you just forget to rebind a quad. For example, you update your module, updates some of the quads, but forget one. You then a few days later take that quad out to fly and realize you forgot to rebind it. Quickest way in that case is to take off the props, plug in a pack and hit the button. This is the only Rx I've damaged out of 15 or so of them.

[@HeraklionFPV]

@@PinchTune Yes it happens. Today i tested the diversity Nano RX and i was extra cautious with the button and the heat shrink. :D

[@PinchTune]

@@HeraklionFPV Good! I just re-bound one using the button. But of course, as I said in the video, I use soft heatshrink now, so not a problem. :)

[@danjensen9425]

I’ve don’t that.

[@FarmerFpv]

That's a big log, do you have needle nose pliers big enough to stretch the heat shrink over the log? Lol

[@PinchTune]

Harbor Freight has everything dude. Haha.

[@ThomasShue]

Wow, that video was difficult to watch. It too 3 mins to say the thin shrink tubing that comes with the nano rx is too rigid once shrunk, and you have to press too hard and will break the rx. Wow. might I suggest a small hole cut into the heat shrink ro stop this problem
