I have been using these props for all the my Ultra Light 5" builds like the 2Fiddy, Rakon 5, and Transformer 5". These props are very quiet and lots of grip. I also like how durable it is compared to the HQ props I was using. I never had any issues with the prop exploding at the hub like the HQ props. But some would say it was my fault because I over tighten them. :)
Just enough to give my ultralight extra punch! I will recommend!
