Hi - I have the motor that’s in the pictures I posted - it has similar specs to a graupner 700 but is out of a leaf blower 🤣.
I found an m5 45mm prop but not a counter rotation option so I will ha e to see how it goes with two right hand rotations . Anyone noticed much prop walk/ torque issues here ?
As a back up I have also purchased two 5mm to 4mm shaft couplings which are designed for motor to shaft applications but I might try and adapt them to the prop end by cutting an m4 screw for the prop end and attaching the prop that way if the props I have ordered don’t work.
Thanks for your help - it’s greatly appreciated
