RC tools: calculators and model pictures
Free calculators for setting up your models, handy converters, and picture makers for your radio's model screen - no account needed.
How to start
- Open RC tools from the menu (or rcflyerpro.com/tools - it works without signing in) and pick a tool.
- Choose Metric or Imperial at the top of a calculator - it remembers your choice, and any numbers you've typed convert across.
- Fill in the boxes - the result updates as you type. Boxes marked optional add extra checks, like your ESC or stall speed.
- Read How it works under each calculator for the formula and the rules of thumb behind the result.
- For a radio picture: pick your radio, choose a photo (or one of your model photos), frame it, remove the background if you like, then download it - or save it to one of your models to download again later.
Tips
- Calculators: CG, wing loading, flight time, LiPo C-rating, prop thrust, prop pitch speed, motor and prop, power-to-weight, servo torque, and turbine fuel and flight time.
- Converters: an RC unit converter (weights, lengths, speeds, servo torque, wing loading, fuel) and a petrol and oil mix calculator.
- Results marked as estimates depend on your exact parts - check the maker's data and measure with a wattmeter or scales at the field.
- Radio pictures are made in your browser - your photo is never uploaded unless you save it to a model.
- Saved radio pictures are on the model's page under Radio pictures, with a Download button that keeps the file name your radio needs.
