Bench-test note: Performance values are measured test data, not guaranteed aircraft-level performance. Current draw, thrust, efficiency, RPM and temperature vary with propeller, battery voltage and sag, ESC behavior, airflow, ambient conditions and test equipment. Higher KV, larger propellers and higher voltage increase system load; select the motor winding, propeller, ESC, battery and cooling for the complete aircraft.

Flight Controller / VTX Warranty Policy
 
At weBLEEDfpv, we are committed to providing high-quality products. However, due to the technical nature of flight controllers and VTX's the precision required for installation, our warranty policy for flight controllers is as follows:
 
1. No Warranty Post-Soldering: 
   Once any soldering has been performed on the flight controller / VTX's, we are no longer responsible for replacements, repairs, or refunds. The process of soldering can introduce various factors that may lead to damage, and we are unable to control or verify the conditions in which the soldering was conducted.
   
2. Pre-Soldering Inspection: 
   Before you begin soldering, we recommend carefully inspecting the flight controller  / VTX's for any potential issues. If any defects or issues are found prior to soldering, please contact us immediately for a replacement.
 
3. User Responsibility: 
   Soldering requires skill and experience, and improper techniques may result in damage to the flight controller, including but not limited to overheating or lifting solder pads. Please ensure you are confident in your soldering abilities before proceeding, as we cannot be held liable for any damages caused during installation.
 
4. Final Sale: 
   All flight controller sales are final once the product has been modified or soldered. We are unable to offer returns or exchanges on used or modified products.

⚠️ FPV DIGITAL SYSTEM NOTICE

HDZero, Walksnail, VTX systems, and ultra-micro FPV electronics generate heat quickly while powered and require proper handling during setup and troubleshooting.

Bench setup without airflow/cooling can result in excessive heat buildup.

Once powered, configured, firmware updated, soldered, flown, or modified, products are considered used.

Manufacturer warranty may apply for BNF drones and electronic systems.
