We got tired of parts that did not fit.

SkyBit is an FPV shop run by people who fly what they sell. The reason this site has a 3D builder is not that 3D looks good on a shop. It is that the usual way of buying drone parts, a list of dropdowns and a lot of hope, ends with a box of components that turn out not to go together.

A 30.5mm stack does not bolt to a 25.5mm frame. A 16x16 motor does not sit on 12x12 arms. Both are knowable before anyone spends money, so the shop knows them.

What the shop checks before it takes your money

Ten rules run against every configuration, in the builder and again when the shop asks whether a part fits the build already in your cart. Six of them stop the order. Four say their piece and leave the decision to you, because a pack that sags under a hard punch is a judgement call and a stack that does not bolt to the frame is not.

Stops the order

The parts physically cannot go together.

Stack against frame
A 30.5mm stack does not bolt to a frame drilled 25.5mm. The holes are 5mm apart.
Motor bolt pattern against arms
A 16x16 motor will not sit on 12x12 arms. Two of the four screws land on carbon.
Prop diameter against frame clearance
A 5.1in prop on a frame rated to 3.1in strikes the arm on the first roll.
Pack cells against motor rating
A 6S pack through a motor wound for 4S runs the windings past their voltage.
Pack cells against ESC maximum
A 6S pack into a 4S ESC fails the capacitors, usually on the first arm.
Thrust against weight
Below 2:1 the craft will barely climb and cannot pull out of a dive.

Says so and lets you decide

It will fly. You should know this first.

Peak current against ESC rating
42A per motor into a 25A ESC is fine for short punches and hot on a long climb.
Pack output against motor demand
A 25C pack behind motors that want 180A sags. It flies, it just will not punch.
Prop size against frame class
3in props on a 5in frame fly, and leave thrust and efficiency unused.
Thrust to weight, high and low
Under 4:1 is soft for freestyle. Over 14:1 is a racing setup and twitchy to learn on.

Every picture here is the part, drawn from its own measurements

There is no photography on this site and no per-product 3D model. 9 archetype meshes are generated from a script, and the scene scales them by numbers out of the catalogue: plate width, arm length, bell diameter, board size, pack length.

Adding a product is a row of numbers, not a modelling job, and the render and the live builder cannot disagree because both read the same row. The product images are exported from the same layout function the builder runs in your browser.

Four motors, framed at one scale

Every render in a size group is framed at the size of the largest member, so a 1404 micro really does look smaller than a 2806. Framing each product to fill its own tile throws away the most useful thing an image can tell you.

What happens after you place an order

  1. You configure it

    Pick the parts in the builder. It checks mounting patterns, prop clearance, cell counts and current headroom as you go, and will not let a combination that cannot physically go together reach the cart.

  2. We build and bench it

    Soldering, a Betaflight configuration for your exact parts, motor direction, and a props-off arm test. Anything that misbehaves on the bench does not get boxed.

  3. It ships from Batumi

    Packed with the spare hardware from the frame kit and a printed parts list, so a repair a year from now does not start with guesswork about what is in there.

What is not built yet

This is a young shop and some of it is honestly unfinished. It is better that you read it here than find it at checkout.

Card payment is not connected
Checkout collects your details and clears the cart. The Bank of Georgia and TBC pages are not wired up, so we call you to take payment. The redirect point is marked in the code.
The catalogue is a file, not a database
Every part lives in one TypeScript file. Each field was written to become a Postgres column, so moving is a schema translation rather than a rewrite, but that move has not happened.
No accounts and no order history
The cart lives in your browser and nothing about you is stored on a server. Stock is read from the shop's own inventory: where a product is linked to it, the number on the page is the number on the shelf, and where it is not, the page gives no count rather than a guess.
Performance figures come from spec sheets
Weight, thrust to weight and hover time are computed from published manufacturer numbers, not from a bench test with your pack. They are labelled as estimates everywhere they appear.

We fly the same parts we sell, and we post the footage.

The builder is free to use and there is no account to make. Take a configuration as far as you like and see what it says.
