A new paradigm in FPV frame design and 3.5" performance
Forget everything you know about frame design.
That’s what I did when this concept came to me (in a dream none the less lol, not even kidding here’s the doodle I scratched immediately after waking up)

This frame executes a simple idea in a variety of novel ways that all converge into a single purpose; uncompromised performance.

As you already know, I only like to make stuff I wish existed; and this frame is exactly that; it might not be the most robust or easiest frame to assemble or repair, but man does it hauls 🍑.

I would rather get this out of the way immediately, if you’re not confident in your building skills or you’re thinking of going bando bashing with it, this isn’t for you.

However, if you’re not one to shy away from a challenging build, and you want to push your flying to new levels, my guy do I have something for you.

Vertical, pretensioned, interlocked arms.
At the heart of the concept, the arms make the center piece holding everything together.

The vertical arms induce little to no prop obstruction, making the frame exceptionally quiet, efficient and fast.

Try lowering the nose on a juicy flick to engage warp speed as the arms align with the airflow.

This carbon fiber orientation also brings more rigidity to the frame than it has any right to be for 1.5mm thickness.

The pretension comes from tying the the tips with the motor plates, enabling remarkable motor vibration dampening.

This enables running with extremely lean filtering, improving pidloop latency and connectedness.

Lastly the interlocking arms makes for a uniquely stable assembly without the need for numerous hardware and high clamping force.

Meanwhile leaving the center open for electronics, safely nested within the heart of the frame.

Few but mighty printed parts
Quick swap, flexible battery mount
Stretches to size to quickly slide batteries in and out.

Lighter than a velcro strap, latches in place and adapts to any battery size, from 3 to 4S, ~450 to 650Mah.

Or for any other odd size the slots perfectly fit a 12mm velcro strap as well.

In addition, the TPU lipo pad helps keep the lipo from sliding, while offsetting it from the bottom sunk nuts.

Motor spacers
Structural components that help distribute the motor clamping force between both motor plates

Wingman HD Camera mount compatible
The cam pod has the same accessory slots as the Wingman for a HD cam, GPS or other.

Super efficient, stealthy and long flight time

Enough about how it’s made, how does it fly?

Well you can expect unparalleled performance out of that format.

The combination of super light weight, low prop obstruction and high rigidity make for an explosive cocktail that’ll leave you speechless.

Fly faster, further and longer than you ever have on a 3.5″

The survival cell
The whole geometry of this frame revolves around the ability to install the electronics within the center area of the arms.

While it does constitutes the major part of the assembly difficulty I mentioned earlier, it also makes for one of its strongest benefits.

To get the sticking point out of the way first, what I meant by hard to build was really just that it will only fit up to 33x33mm boards, and stack up to 12mm height

Which prevents a lot of current whoop AIOs to fit, but still leaves a few excellent options such as the HM CrazyF411 or the TBS Podracer AIO.

And while leaving a fairly tight space to work with, the whole stack actually assembles out in the open to the top plate that can then be then be lowered whole into the cell.

However this all should be no trouble with a little building skills and/or patience 😎

To sum it up

The X-Bow is simply a cutting edge prototype race/freestyle frame made for the most extreme pilots out there.

  • If you’re not afraid of a challenging build that will push you to improve your building skills
  • If you want to experience a new level of speed and responsiveness in your flights
  • If you want a silent and stealthy freestyle rig to rip around town without alerting the whole block
  • Whether you’re into juicy, sbangy freestyle flying that could benefit from the bonkers acceleration
  • Or you’re a 3 or 3.5″ spec racer that could use the extra top end and low weight in your courses
  • Or you’re just a sicko like me that would ride a Koenigsegg to the grocery store

Well then if any of these sound true, this was made for you too.

Build recommendation:

  • Motors: 1204 ~5000KV for 3″, 1404 ~3500KV for 3.5″.
    Props: Gemfan 3″ 3028-3 or 3.5″ 3525-3
  • AIO: Any 15-20A, 3-4S as long as the OVERALL DIMENSIONS NOT OVER 33x33mm
    See our Happymodel CrazyF411
  • Camera: Any 14mm micro cam. See our Caddx Ant
  • VTX: Analog: Any nano size VTX; see our TBS Unify Nano Pro32
  • HD FPV: HDZero Whoop Lite works great, walksnail should fit as well -untested-
    As long as your stack fits within 33x33mm wide and 12mm tall you should be good to go!
  • Battery: The strap should allow you to use about 450 to 550, 3 to 4S Lipos.
  • For weights, expect about ~72g for 1404 / 3.5″ and ~62g for 1204 / 3″

Best affordable squeaker toy
Color: Crinkle Chicken (Brown), Size: Large, Color: Crinkle Chicken (Brown), Size: Large
my dog is obsessed with this toy, this has became his new comfort toy and after having this for about four months the legs are falling off but it’s very durable. The squeaker also moved from the head of the chicken to the body of the chicken but that’s after it was played with every single day. I love that it has two squeakers and it’s the perfect toy for my dog.

My dogs favorite toy EVER
Color: Crinkle Chicken (Brown), Size: Large
I have a Belgian Malinois who loves any and every toy, but this one is definitely her favorite. She will walk around the house constantly carrying it in her mouth, which is honestly adorable to watch. The squeakers only lasted a couple of months, but I don’t really consider that a downside—I’m kind of grateful they didn’t last forever given how much she plays with it. It still remains one of her most-loved toys even without them. My only word of caution is that if you work from home, this toy makes a lot of crinkling noise. And I mean A LOT. It’s great for keeping the dog entertained, but it can definitely get a little frustrating for humans trying to focus or take calls. Overall, it’s been a big hit in our house and easily one of her favorite toys.

Super cute
Color: Bunny (Mauve), Size: Small
Super cute and fuzzy. Definitely perfect size for a puppy and not too loud. The fur is very soft and the nose is sown on not a hard piece that can be chewed on. Very good quality too.

Normally amazing
Color: Spiky Ball (Blue, Orange), Size: Medium
We have purchased these slightly spiky dog balls several times for our very strong jaw heavy chewer dogs and they’ve been amazing. They don’t break down they don’t get torn apart the squeakers don’t even pop out of them. So we ordered another package because we’ve lost a few outside to the lawnmower… oops and the package that got delivered today had only one ball that squeaks and the other does not. THIS IS A PROBLEM ! Unfortunately my female dog got to the new squeaking ball first and my male got to the non-squeaking ball and he was NOT happy. Basically once they claim a ball it’s theirs and the other dogs don’t go near the ball they claimed. So he’s following my female around and every time she squeaks the ball and I’m just waiting for him to attempt to take it from her causing damage to her. Normally… These are amazingly fun, tough, durable but also squeaking balls (that’s rare in a tough ball) that my dogs absolutely love. This time just got a bad batch I guess. When they squeak the dogs LOVE them. After several months of play the squeaker might break inside of the ball but the ball never comes apart or gets damaged. And we as the owners love that they don’t break down are not able to be ripped or torn even by our very strong jawed and big jaw muscle dogs. They are also great for in the house play because they’re small enough that they fit completely inside our dog‘s mouth but obviously not small enough to get swallowed so when we throw them in the house for fetch the dogs can jump up and catch them fully in their mouth so they don’t cause any damage to the walls when they hit the walls. They’re not super heavy but they’re incredibly durable. Definitely worth the price especially if you have heavy chewers or big jaw muscle dogs.

Best fun indestructible toy
Color: Crinkle Duck (Yellow), Size: Large
Truly indestructible no matter how much our oittie tries. She has owned it for three months works at destroying every day with no success. She carries it everywhere. Best purchase for chewer, more fun than the popular rubber heavy duty toy. Do not hesitate your pup will thank you for this fun distraction.
