Octopick18 Kit 1.5mm (Carbon Only)
$ 18.97This frame kit is designed for 1S (flat) octocopters of 45mm props using AIO FC (F405 or above) and small 1S 4-in-1 ESC (rarely seen these days) to enjoy outdoor 1S digital FPV. To build this kit, you need to know how to use additional motors in Betaflight. For more detaile, please refer to my article submitted to Rotorbuilds ( https://rotorbuilds.com/build/30046 ) in which I made 1S octocopter of 40mm props for analog FPV.
- Kit Weight : about 12g (carbon only)
- Necessary Standoffs : 5 M2x18-25mm for Top Plate (depends on the height of VTX); 4 M2x20mm and 1 M2x14mm for Camera Mount
Notes
- 40mm camera cable in HDZero Whoop Lite Bundle is short, which limits camera angles.
- Insertion slots for Camera Mount Side Plate may be too narrow. If this is the case, please widen them by fining.
Bottom plate
- Designed for 1S octocopters of 45mm props
- Optimized for using AIO FC (F405 or above) and small 16x16mm mount 4-in-1 ESC
- Recommend combination is JHEMCU GSF405A and Racerstar Star4
- Motor Mount : φ6.6mm, M1.4 ; φ9mm, M2 (RCinPower 1003)
- Thickness : 1.5mm
- Weight : about 7g
Top Plate
- Designed for mounting VTX and Camera
- Compatible VTX Mount: 25.5x25.5mm, 20x20mm
- Thickness : 1.5mm
- Weight : about 2.5g
Camera Mount Side Plate
- Commpatible camera width : 14mm
- Mount Screw Holes : 2mm, 1.4mm (HDZero Nano Lite Camera)
- Suitable Standoff Height : 20mm
- Thickness : 1.5mm
- Weight : about 0.8g
Note: The 1.5mm-thick CF plate may not be able to be inserted into the kit top plate or camera mount top plate because the thickness varies from lot to lot. If this is the case, please widen the insertion hole by filing. However, even if it is too thin, it will not be a problem as it will be secured by the four standoffs on the camera mount.

Each arm, consisting of two bones, is supported not only by two adjacent arms but also by its diagonal arm. Replacing broken arms is not as easy as with a regular frame, but the interlocking of the eight bones eliminates the need for upper and lower plates for fixing.
As a toothpick frame (2S or above), it does not appear to be disadvantageous in terms of robustness or vibration in the field tests to date. This 3" modular frame is more robust than it looks.
- Wheelbase : 127.3mm
- Total thickness : 5mm (2.5mm each)
- Motor mount : φ9mm, M2 (2pcs. each)

Bone-Hex 3inch 2.5mm
$ 17.68This frame is designed for a toothpick style hexacopter.
If you want to mount additional ESCs under the frame, the Minimal Bottom Plate 1.5mm is reccomended for protecting them.
- FC and ESC mounting holes: 25.5x25.5mm, 20x20mm, 16x16mm, M2
- Motor mounting holes: 9x9mm -12x12mm, M2
- Weight: About 9.5g
- Betaflight Motors Mixer: HEX X
The recommended prop size is 3". As for 3.5", it is possible but a little bit tight for mounting a battery.
Using a not-too-simplified AIO flight controller which has enough soldering pads such as two sets of UARTs and a LED strip, it is not difficult to build a hexacopter by adding a 4-in-1 ESC or two individual ESCs. The following picture shows an example of a 3" build using a JHEMCU GHF13AIO FC F411 2-4S 13A with a 16x16mm 4-in-1 ESC by Flywoo.
GHF13AIO has soldering pads for LED_STRIP and I2C, I used the LED_STRIP (A08) pad for Motor 5 and the SCL (B08) pad for Motor 6. The corresponding CLI diff are as follows:
# resources
resource MOTOR 5 A08
resource MOTOR 6 B08
