Precise Center of Gravity Tool for CARF ViperJet
Print Profile(1)
Description
This self-designed CG Tool (Center of Gravity Tool) was specially developed for the CARF ViperJet 2.50 m and is 100% field-tested.
The tool is attached between the fuselage and the wing. With the help of a builder's line, the complete model can be easily, safely, and reproducibly balanced – even alone in the workshop.
✅ Why this CG Tool?
The included CARF tool offers:
- ❌ too few adjustment points
- ❌ incorrect center of gravity positions
- ❌ no possibility to set the truly optimal center of gravity
👉 The ideal maiden flight center of gravity for the ViperJet is approx. 10 mm behind the wing tube – precisely this point is not provided by CARF.
🚀 Advantages of this CG Tool
- ✔ Center of gravity adjustment in 5 mm increments
- ✔ Free choice of CG according to personal preference
- ✔ Very high repeatability
- ✔ Quick & easy to handle
- ✔ Perfect for maiden flight and fine-tuning
- ✔ No modification to the model necessary
🛠 Technical Notes
- Designed for 3D printing (PLA / PETG recommended)
- Precisely fitted for CARF ViperJet 2.50 m
- Use with standard builder's line
📌 Note: The responsibility for correct center of gravity adjustment lies with the user.
