Have you done anything to counter roll on yours ?
The 7" APC sport props that everyone seems to love so much are very heavy. They all suffer from significant torque roll. In fact, nearly all of my launch crashes were related to torque roll on the APC sport props. I eventually stopped using them.

The best 4S and 5S prop for going fast is actually the stock prop. If you want more thrust and you have an 80+amp ESC, get an Aeronaut 7x7. It's an extremely light carbon prop that has no torque roll issues and better thrust than the sport props. I've been using one of them on 4S for over a year now. Pulls a little over 1100w static and is good for not just unlimited vertical, but some very spirited unlimited vertical, and around 120mph level flight. Good batteries are obviously a must.

Conversely, I lost a prop in flight one time after I had glued the nose and had one shot to make a landing on a windy day. Ended up flying the plane to the ground rather than truly landing it. It skidded a good 100ft across a parking lot at 50+mph, hit the curb on the side of the nose, then launched into the air and hit a plastic fence. The nose stayed attached and only suffered some deep scuffs. Rest of the plane was fine.
+1 on this. Iv glued my nose on as iv lost a few coming out of dives or real tight turns and asd Awd said, it still damages the fuse on a crash anyway. And I also dont like the 7" sport props, iv had good success with the apc 6.5x6.5 pylon props on 4s.
