QuadCalc

Build the quad before you buy the parts. QuadCalc is a free FPV drone build planner that runs in your browser. Choose a frame, motors, props, battery, flight controller, ESC, VTX, camera, receiver and goggles from more than 1,100 real components, and it checks that everything fits and works together. As the build comes together you see the numbers that matter: total cost, all-up weight, thrust-to-weight ratio and estimated flight time. Swap a motor or a battery and watch the trade-offs move. - Compatibility checks across frames, motors, ESCs, flight controllers, VTX and goggles - Live estimates for cost, weight, thrust-to-weight and flight time - A guided build that takes newcomers through each part, step by step - More than 120 real builds from FPV pilots to start from or learn from If you're new to FPV, it stops you buying parts that don't fit. If you've been flying for years, it's a quicker way to plan the next build. Free. No account.
