Ordering custom carbon fiber airframe cuts? Learn how the service works, what to measure, and how to avoid costly mistakes before you checkout.
Quick answer
Order custom carbon fiber airframe cutting when you need precise, repeatable tube lengths and want to skip the dust and setup of cutting carbon fiber yourself. Measure each piece, account for the saw kerf, and submit clear cut instructions at checkout.
Why carbon fiber airframes are worth cutting professionally
Carbon fiber body tubes are stiff, light, and abrasive. Cutting them at home creates fine conductive dust and can fray or splinter the edge if you use the wrong blade or rush the feed. A cutting service removes that risk and gives you clean ends that are easier to bond and finish.
The trade-off is planning. You must know your final piece lengths before you order, and you lose the ability to trim on the fly. If your design is still changing, wait until the dimensions are locked.
How the per-cut pricing works
The service is priced per cut, not per tube. That means a single tube cut into three pieces counts as two cuts, while three separate tubes each cut once also counts as three cuts. Count the number of cuts you actually need, not the number of finished pieces.
Because fall-off pieces are shipped back to you, you are paying for the full tube either way. Plan your cuts to get the most useful pieces from each tube and keep the offcuts for couplers, test fits, or future repairs.
What you cannot assume about the service
The catalog does not list tolerances, finish options, or maximum tube diameter for cutting. Treat those as unknowns until you confirm them with the store. If your build depends on a specific edge squareness or a polished end, ask before you order rather than assuming.
The saw kerf is 3/16 inch. That material is removed with every cut, so your finished pieces will be shorter than the tube you started with by roughly that amount per cut. Build that loss into your cut list.
Decision rules for ordering custom airframe cuts
- Count cuts, not pieces: If one tube becomes three pieces, that is two cuts. If three tubes each need one cut, that is three cuts. Enter the total number of cuts in the quantity box. Double-check your count against your cut diagram before checkout.
- Write a cut list with tube and lengths: In the Custom Order Details section, state which tube to cut, then the length of the first piece, the second piece if applicable, and the third piece if applicable. Use the same units throughout. Keep a copy of the exact text you submit.
- Subtract the saw kerf: The saw removes 3/16 inch per cut. If you need a 12-inch finished piece from a single cut, the starting tube must be at least 12 3/16 inches. For multiple pieces from one tube, add 3/16 inch for every cut. Add the kerf allowance to your tube order, not to your finished piece lengths.
- Decide based on design stability: Order the cutting service once your piece lengths are final. If you are still testing coupler fit or motor mount placement, cut the tube yourself or wait, because the service cannot un-cut a tube. Lock your dimensions before you pay for cuts.
Product facts
- Custom Airframe Cutting - Carbon Fiber Airframes: PML will cut your airframe for you; you enter the total number of cuts in the quantity box and describe the tube and piece lengths in the Custom Order Details section at checkout. Knowing the order form asks for cut count and piece lengths helps you prepare a clear cut list before you reach the checkout page.

Is custom cutting right for your build?
Best for
- Builders who need multiple identical-length pieces from carbon fiber tubes
- Anyone without a dust-controlled shop or carbide cutting tools
