Wrench for Racerstar Sprog motors. Does exatly what you think.
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.
Just slide it from side around one of the three arms on top of the motor and tighten the prop nut.
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.
As a bonus
