This is a 3D printed scale Bell 412 fuselage designed for the OMP M1 helicopter. It is not tested with other direct drive helicopter, but it may fit the other helis that are similar in size such as the Eachine E150, and the Goosky S1. The great thing about the OMP M1 is the power to weight ratio, which allows it to fly the 3d printed fuselage and still maintain its flight performance.

  • Scale: 1/42
  • Printing Material: PLA with 30% infill, with 0.8 mm wall thickness to all the parts
  • Rotor Blades: Replaced with old 150mm Lynx 30-R
  • Skid Support: 1mm thick steel wires wrapped with 1mm heat shrink tubing
  • Dimensions: Length: 310mm (Nose to tail); Width: 60mm; -Height: 65mm (Not including skid)
  • Weight: 48 grams (3D printed fuselage only); 172 grams (Total flying weight)
  • Flight Time: 4:30 (Main and tail motor stays cool)

Additionally, the fuselage design incorporates six magnetic points, using 12 neodymium magnets (3mm diameter x 3mm long) to connect the front and middle sections. This design facilitates easy access for changing the battery.

You can look for hours for a scale fuselage for the M1 and M2, there are a few but not the type I am looking for. They are fibreglass, not light and expensive. So when I found this model, got it, printed it in colorfabb lightweight pla, came out OK. Lots of stringing to clean up but that's normal with this material. I am going to try nylon 12 for the undercarriage then sanding and painting. Bit worried about the tail motor holder, if it fails then crash, so I will make out of 3mm aluminium and glue that in. End result with a bit of effort is impressive, so well done rcsplitair and keep them coming.

The design is amazing!! Everything fit perfect. I printed mine with PETG instead of PLA. Looks so good in the air and I couldn’t be happier with this build! Thank you for creating it.

Very nice model. Shape and size are accurate, fits the RC gear wonderfully. Prints great. Needs minimal supports. Thank you.

Excellent piece of kit! Prints easily, is beautifully detailed and the OMP M1 indeed drops in like a glove. The model is very strong and can be handled without being afraid to break anything. I'm making mine like the Dutch Coast Guard and there are free parts available for this upgrade ( radome, hoist amongst others). I vase-printed the tail boom vertically (opposed to as intended), I also vase-printed the hoist and horizontal stabilizer on my Creality Ender 3 V2 with Ultimaker Cura (0.12mm detail) with regular PLA. The skid cross-beams are made from bent 1mm steel rod, using the printed parts as template. I looked at pictures online to determine the location (I ended up with the forward side of the cross-beam being flush with the fuselage mid section front). I used a rat tail sander to make a groove for the steel rod, so it "fails" into the fuselage a bit. The prints are all dry sanded with 60-80 grit to get rid of the print layers, followed by a wet-sand with 150-180 grit. A first layer of primer is sprayed and then sanded with 600 grit (dry). For filling I used Tamiya plastic putty (marble dust) and sanded again.
