Sorry to hear about your engine trouble,but congrats on no damage
I had the carb screw fall completely out in flight on my O.S. .46 on its fourth flight breaking in,
It lost power and started sputtering and landed dead stick.
Preflight I double checked every bolt on the plane but that one. I bought a pack of two allen head screws from the hobby shop.
Its good and tight now! I dont forget about it anymore.
I was all set to fly mine today,but the good ol Kansas winds were little too strong,maybe tomorrow.
I took out about half the up thrust on mine by placing washers on each side behind the motor mount.
I did th same on my 60 size extra 330L and there is very little change from half to full throttle. Although i dont usually need full throttle.
Good luck tomorrow[8D]
