Default Mini magic Extra .20

I never thought this plane would be very quick, But wow i did my first flight yesterday and it was nutz.
Iv got a OS 25FX running a Master Airscrew 9x6 Plane weighs 2lbs 2 oz and the motors producing 4lbs 7 oz's of thrust.
Me and my buddies were guessing maybe around 70MPH in a diving pass, were just waiting for the wing to fold, i went through the whole fuse with thick CA and reinforced every joint and every stress point. But after landing i knowticed i completly sheared the gears in one of my HS 81 servos in the left wing.
Im running a 6v RX battery so there putting out about 46oz of tourqe, so i decided to rebuild all of them with the metal gear sets.

Do you think that will be enough for a plane this fast??
It made the strangest noise in high speed passes like a low pitched wistle almost, anybody know what that may be ??

Thanks for all future help [8D]
This is my first post on these boards, thinking i could really get into fast planes after flying this.

You may have flutter that stripped the gears in your servo. Metal gears wont help if that is the case. The high speed pylon guys usually use nylon gears.
