Replacement Frame and Prop Guards
- A modular system which utilises the stock carbon and TPU portions of the Gofilm20 but allows you to quickly replace the plastic parts in the event of a breakage. Choose your VTX base plate (with or without rings), add the printed standoffs (x4 25mm, x1 22mm for the central rear standoff), then attach the prop guards to the carbon. You will need new screws to secure everything in place.
- Print the orange parts in PETG using 8 wall and 100% infill and the yellow in TPU.
¶ HOZV20
A new version of 3D print frame was designed by HOZV (formerly OzAk) inspired by the original replacement design. Design was tested and flown.
Rationale for design:
- Lack of important features and protection measures
- Too brittle original plastic frame
- Faster reproductible setup if a 3D printer is available
Feedback is welcomed for improvement.

¶ Real life pictures
¶ Step response
Here's the step response analysis done using PIDToolBox. Orange is using 4 blade prop, Red is using 5 blade prop. Both provide very decent and stable flights.

Dump made for Betaflight 4.5.1
¶ Important mentions and notes
-All parts were printed in PLA. VTX+XT30+ELRS holder and Camera holder can be tried in TPU or PETG. Materials not available for test.
-The new build was tested using 4S 650mAh CNHL Ministar and 4S GNB LiHV 720mAh. Recommended GNB LiHV 720mAh
-Build is custom, the only original part is the CADDX GOFILM20 frame and Moonlight Camera + VTX.
-Flight time was tested: 4:30 with 4S 650mAh LiPo CNHL Ministar, 5:30 - 6:00 with 4S 720 GNB LiHV . Paradoxally enough, 720mAh is 10-15g lighter also.
-The following parts were used:
- T-Motor F1404 4600KV
- HappyModel Super F405 HD
- Matek BEC 12V
- Matek Lost Model Beeper
- Gemfan D51-5 Blade
