Estimate RC plane propeller diameter, pitch ranges and thrust requirements from aircraft weight, wing geometry and flying purpose.
Enter values or load an example.
Enter your aircraft weight, wingspan and wing area, then choose a flying purpose and motor count. Add the operating conditions, lift coefficient, motor weight limit and planned propeller dimensions. Calculate to explore suggested diameter and pitch ranges before selecting a specific powertrain.
Read stall speed, target speed and total thrust as aircraft requirements before choosing components. The thrust target covers all motors combined. Propeller diameter guidance depends on aircraft geometry and motor count; pitch guidance also uses the entered diameter, blade count and flying purpose. Recalculate when any of those inputs changes.
No. These are sizing targets, not measured thrust or a verified motor and propeller match. Review any example values before relying on the result. Use the fixed-wing calculator next to estimate the performance and electrical load of a specific motor, battery, ESC and propeller.
Setup Finder estimates aircraft requirements and propeller size ranges; it does not select or verify a specific motor model. Use those targets to choose candidate components, then evaluate the combination in the RC plane propeller calculator.
The thrust target is the combined requirement for all motors. Keep the motor count consistent with your aircraft when interpreting propeller sizing results; a total thrust target is not a measured output from one motor.
Check physical clearance and the motor, ESC and battery limits for each candidate setup. The suggested diameter and pitch are starting points; calculate current draw and thrust for the actual components before choosing a combination.
