This thing is DANGEROUS!!!
I was using this on a 250W setup on 3S to pull an antique 1500g thermal glider, treating everything very cautiously. Both prop blades and the aluminium cone tore off on powering up the motor on the 6th flight. The blade material is ridiculously, i consider this a dangerously inferior item.

Beautiful workmanship - 5 stars

Mechanical design spinner - 5 stars

Mechanical design Hub - NO STARS

Propeller blades - Don't know yet....

Assembly design - NO STARS



The propeller blades have 6mm wide hub, and the mechanical hub has spacing for an 8mm hub propeller. This is an unusable design and is ABSOLUTELY UNSAFE !!! (See previous reviews.)



The mechanical hub extensions are actually BENT to 7.50mm spacing. ...will not engage an 8mm prop.

Do not exceed 300 watts as the blades will fail!
