William Fraser's video: Solar kayak - new propeller test

Why an aircraft propeller? More on that here: https://youtu.be/4kL66c6T9po DIY 18V electric outboard motor. HRS 775 cordless drill motor and gearbox, APC 8" x 4" model aircraft propeller. First successful test with a brushless motor and new panel: https://youtu.be/6u-j1gxQRGc Trolling motor construction video: https://youtu.be/xgOfI49nCCM Nearly triple the propulsive power compared to the drone prop ( https://youtu.be/Yx29XnPp6Z0 ). No battery or MPPT electronics. The aim of this project is to optimise the solar-motor-propeller match. The solar panels have since been replaced with a 300W mono-crystalline smart panel and MPPT controller. The brushed motor has been replaced with a brushless motor and an entirely new drive train: https://youtu.be/wys0oQKtMpM
