Preguntas Frecuentes (FAQ)

Q: What are the minimum and maximum recommended motor sizes compatible with the AlfaRC LR5-Grasshopper, and what are the implications of choosing a motor outside this range?
A: The AlfaRC LR5-Grasshopper is compatible with 14XX and 15XX brushless motors. Choosing a motor outside this range could negatively affect performance. A 14XX motor will provide more torque, ideal for tricks and slower flying, but could limit top speed. A 15XX motor will offer higher speed but may sacrifice some torque. It is crucial to consider the motor's KV (RPM per volt) relative to the battery voltage (3S or 6S) to optimize performance and avoid overheating.

Q: The frame has 20x20mm mounting holes for the flight controller. Which flight controllers are commonly compatible, and what should I check if I plan to use a different flight controller?
A: The AlfaRC LR5-Grasshopper is compatible with flight controllers such as Tower, Kiss, F4, F3, Naze32 and CC3D systems that use a 20x20mm mounting pattern. If you plan to use a different flight controller, check that it has this mounting pattern. Also make sure the flight controller has enough processing power to handle the FPV components you plan to use (camera, VTX, etc.) and that it is compatible with your ESCs' communication protocol (for example, DShot).

Q: The frame weighs 63g. How does this weight affect flight time and the drone's agility, and which components can I choose to minimize the system's total weight?
A: A frame weight of 63g is relatively light for a 5-inch drone, which is beneficial for flight time and agility. However, what really matters is the total weight of the system (including motors, ESCs, flight controller, camera, VTX, battery, etc.). To minimize total weight, choose lightweight components such as high-efficiency ESCs, compact flight controllers and low-weight FPV cameras. A smaller battery (within the recommended 850-2200mAh range) will also reduce weight, but at the cost of shorter flight time.
