A 3" frame for Nano cams, accepting two boards in 20x20 or 25x25, and have a 20x20 rear mount point (even a few mm slideable).

The arms are thick, the build quality decent, the 3D prints fit, it comes with a rubber pad and a strap and is also pretty light.

Not in the realm of perfect are the cheap screws and the "slippery" standoffs. I normally would reduce this to 4 stars, but for 20 bucks it's still a no brainer.

With this frame you can build a 1404 based 4s650 quad with ~180g AUW and get pretty good performance.

Last week I bounced cam first into a rock and the TPU nose just bounced off the quad and I kept flying. So its also pretty sturdy.

Like I said. A no brainer.

+ They're cheap

+ They're available all over the world

+ They're power is still on today's average of modern 2207

+ They're not overweight

- They bend easier than I expected it. I never broke a 5" arm, but bent several of those motors. Or pin-landing-force-separated the two part bell.

But they're still cheap.

They just work.

My 5" frame runs without a gopro at ~600g. For this weight this mildly ptiched prop delivery plenty of power and excellent propwash handling.

They are pretty robust and even if bent - just bend'em back.

...and I happen to still have ~10 set of it. So I'll keep using it.

The Torvol Pitstop Pro v2 is years old and still a benchmark for FPV backpacks.

Mine is a few years old and starts to wear. The velcro of the inner separators maimed the fabric of the inner walls a little, so the whole structure lost a bit of it's rigidity.

All in all it is still a pretty good backpack for FPV users.

More recently developed backpacks aren't that much better, that I'd improve noticably.

It was a fine frame, back then.

It only fits 20x20 Stacks, has flimsy-thin arms, it's out of production and the vendor doesn't exist anymore.

If you could get one, don't. Look for something newer.

Same for the Micro Reverb.

At least the buld quality was top notch

I bought some of these in 2022. They're all still in use on my old analog quads.

800mW, MMCX connector, a plug AND solder pads. With some cheap FC rubbers for M2 you can mount this M3 VTX on M2 frames and everything's fine.

I rarely needed more than the 800mW, so I don't really felt it necessary to upgrade those.

Its an analog camera with decent picture quality and its cheap. And its shipped with a little joystick for the menu. So on paper it looks like a very good deal.

The massive downside is the terrible delay. Several testers found this camera to add ~30ms to the whole FPV chain. This camera is slower than any modern HD system. No wonder walksnail felt smoother.

Avoid this product: You'll get analog image AND terrible delay.

this wing FC has all the bells and whistles regarding ports and connections.

And its really small.

So great?

Not quite.

Its really small. And is a bit weird to mount. So fiddling the servo connectors to solder and the FC itself into a plane is an annoying task itself.

After that its a truly great FC.

A brutal banger! It's so sturdy, that the motors become the issue.

It's a tight build. Everything bigger that a 20x20 VTX won't fit inside without compromising the rest of the build.

In the end that was the reason I send it into retirement. HD didn't fit inside.

If you search a TrueX armored Quad I would always recommend Botgrinders frame. Unfortunately not this one. The new one. The Demibot. It's got more room for your builds.

It's a frame so cheap you'll feel as if you ripped someone off.

Thingiverse & co provide a lot of 3D prints for the frame.

On the downside this frame was build for a different aera. A chunkin' 30x30/20x20 stack in the middle so badly placed, that you'll strugle to fit a non-nano VTX in there. On the other hand nano cams will feel lost inside. Its just disproportinate and outdated.

Under 20 bucks in the TBS store sound like a steal, but it's actually not.

I used it once: Crash on friday evening and good weather on saturday. The real spare part arrived on tuesday and the Source Two had it's glorious shine on saturday. Then went back into the void of old parts I don't think I could sell.

The module works.

It delivers up to 1W on 2.4 GHz.

The antenna is pretty flimsy, so I unmounted the module during transport. This made the JR connectors wear out (don't know if this is on this module or my TBS Mambo) and the module hs some sudden reboots.

For this reason I mainly use Tracer.

I guess, that fewer mount/unmount wouldn't have led to my problems and would have given me a well made ELRS TX. With a flimsy antenna.

Really. If you buy this get a more rigid antenne. This one is a joke.

The 'regular' one (with one regular antenna) just ... works.

I don't know what else there is to say.

Same size than TBS (the de facto standard size)

Same connections, than any other modern receiver.

Same signal quality than other receivers I have.

Didn't burn itself so far.

So it's ok, I guess

What can you say?

It's small, so it's easy to fit in the plane

It's got ELRS, so you don't have to mind about failsafes

When using ELRS as PWM protocol please note that channel 5 is reserved for Arming and can only deliver 0% and 100%. You have to go on the receivers web interface and remap channels to avoid having a useless channel.

This annoyancs was presented by ELRS

PS: Though betaFPV is the vendor, it still works. Seems to be a good RX for flite-test-like foamies

I had a 180g 3" with Fettec AiO and this RX/VTX. The best quad I ever had. Until it landed in wet grass and gave me magic smoke.

For Tracer pilots this little thingy is a great "keep it simple" device, though not all solder pads are placed well thought.

The VTX delivers over 1W power and Tracer is way better, than its reputation.

If I stayed on analog, I would by a few more.

It delivers 350mW.

The mounting holes can be used to get M2 25x25 and 16x16 and M3 20x20.

What they forgot to tell is that M2 20x20 is also possible by using one of the 25 andone of the 16 holes. Fits perfect.

You also could just sticky pad it on the colling case and put a zip tie around it.

This thing is robust, light, has relatively large solder pads and jsutworks out fine. Solid recommendation for small analog builds.

A pretty good VTX. The exceptional power leads to a very strong signal. Which is good for obvious reasons.

The case seems to have a high buidl quality, but is a bit annyoing to mount.

M2 from below with just a few mm into the vtx (and not through). You have to get screws exactly as long as your VTX mounting plate plus 3mm for a good fit. If you want a bit more air below the vtx you'll have to use some spacers and get new longer screws.

Another downer is the lack of soldering pads. You only get the tiny litte connector with not very long cables. I had serious issues connecting to the solder pads on my FC in my 7" rig. Had to mount the FC sideways with USB directing to the back within the frame. Pretty annoying.

If this thing fits in your quad and you get it mounted well, it's a great VTX. In any other case just get another >1W VTX if you really need that much power.

Excellent googles for analog and HDMI in protocols.

Analog reception was top notch, google fit perfect to my head. A walksnail module had a great fit and a great image quality.

That worked up until some internal error appeared and the google only showed a dark ... nothing.

The replacement with my shop and Skyzone itself worked good (but took ~3 months). I now have a Sky04x v2, which is also great. And works.

I bought this to replace a Jumper T-Lite, which was just too small for my Hybrid-Pinch hands.

My Mambo has a Happymodel 1W ELRS Module in the back and that works out just fine.

The Tango/Mambo-recalibration issue happened only once after the shipped micro SD card broke. Since I replaced it with a proper one the radio never failed on that again.

The biggest downside is, that TBS Tracer never really took off. Don't get me wrong - 30 bucks for a receiver isn't that cheap, but still way less than the Futaba-insanity. And we don't need that many receivers anyway. The biggest bummer is, that there are basicyll no PNP aircrafts with Tracer.

Tracer itself is capable enough to never fail me, so I don't really have a resaon to change.

The Module bay wore out a bit after I attached/detached the module too often, so ELRS has now the risk of a sudden rebooting module (which I worked around by flying basically Tracer only).

Today I would propably buy a TX15, but as I have my Mambo, I don't change and retrain my muscle memory.

Big bonus: The opional transparent case: I spray painetd mine from the inside, so it has an icy look. Awesome!
