Racerstar Sprog motor wrench

<p>Wrench for Racerstar Sprog motors. Does exatly what you think.</p> <p>These motors have in my eyes one big flaw. They have smooth mating surface for propellers. During yesterdays flight I had 2 loose props, so I designed this wrench.</p> <p>Just slide it from side around one of the three arms on top of the motor and tighten the prop nut.</p> <p>I designed this to work with my 2207, but it will also work with 2205 and probably even with 2306 - difference 1 mm in diameter shouldn't be a problem.</p> <p>As a bonus, you can use it like an emergency prop nut tool or to tighten/loosen M3 nylon nuts.</p> <p>If you have any problems with this design or function of it, just let me know and I will try to fix it.</p> Category: R/C Vehicles
