# rc prop calculator

Use this Calculator to assist in the power system selection process.

RC Calculators grew out of these calculators and will constantly be upgraded with more and more features. As with IC, electric motor manufacturers give a specific propeller size range for their motors but it's more critical that the range must be adhered to. DJI has just released the Mavic Air 2. Return to Recreational Boat Building Industry Home Page, Outboard Propeller Manufacturers and Propeller Industry Market Research Page, Propeller Calculator program from Castle Marine, Visit with owners of boats similar to yours that use them for similar activities, Visit with knowledgeable propeller marketing specialists / or a professional at a local prop shop, You might also try a book from Mercury Marine referenced by Stingray Boats as "Mercury Marine has a propeller guide with props for almost every boat. Input a propeller pitch in inches and its RPM to see the theoretical maximum speed in miles per hour. The first number is the diameter of the imaginary disc ('arc') created by the spinning prop i.e. Pitch Speed Calculator. There are countless stories of model pilots losing fingers, or suffering horrendous lacerations to skin on their hands and arms.

Fitting an incorrect prop would mean the engine would still run, but your plane would perform poorly. (a 15 inch pitch prop theoretically propels the boat 15 inches in one revolution). Then, this ratio is subtracted from 1. In one of the videos on the RCexplained YouTube ch, RC LiPo Battery Power & Configuration Calculator, RC Drone Max Distance and Maximum Flight time Calculator, Brushless Motor Kv – Measure a Motor’s Kv, Understanding Electricity – For RC vehicles, Measuring Electricity – Voltage, Current, Power, RC Electric Boats – Guide for Successful Electric Boating, RC Sailboat Controls – Radio Layout, Radio Setup. Pete. By using this calculator you agree to the terms of service of the RC FE Boat Calculator. motor size selections with motors larger than the 540 size. every single complete turn of the prop). Due to prop slip the boat is actually going slower than the theoretical speed. So here we are on 3S, 3 cells, APC 11x5.5 E prop, running 6987 RPM, 959g static thrust, 15.5A, 171.5 W in, 115.8W power out for an efficiency of 67.5%. They recognize our calculator as the inspiration for theirs near the bottom of the page. Enter motor KV and Cell Count The screw with the coarse thread will cut into the wood a lot faster than the fine threaded screw will. PP is the blade pitch of propeller (inches). Does an RC Motor and ESC provide Regenerative Braking.
