Tuning can be a challenge with 6″ props. The success of the 5140 and 5150 props has encouraged Azure Power to create a similar design for their 6″ prop. The 6145 BSP is here. BSP stands for Big Smooth Prop. We can expect to see this design in both carbon and polycarbonate. Not much info has been released by Azure Power, but we know JET (Jordan Temkin) is a big fan.
