Cavfirst,
Yes, that is why they sell brake enhanced version of Revo in Japan.
It is called Revo Elite Aurora. It has 8 magnets instead of 5.
For the people who have trouble casting light weight lures with Revo, you can easily add more magnet. See picture below.
It is in Japanese but you can see how he did it.
This is especially effective on Revo STX.
After adding magnet, you should loosen the mechanical brake so that
you are only using magnet for brake.
you can try diffrent sized magnet or diffrent number of magnet.
I use 2 of 3/16 inch X 1/16 magnet.
