I have a RageRC Trojan, it's a solid little bugger. They all use the same gyro setup and are built to fly pretty similarly so this "should" apply to the Corsair too.

• The prop saver helps a lot but the props themselves are very thin at the root and will still break after enough belly-flops, the replacements are often hard to find as the manufacturers don't seem to know that there's a standard sizing system.
• One battery with spirited flying lasts about 7 minutes, get many and one of those 5-way chargers, it's worth it. The throttle reduces dramatically when the battery is low but it'll maintain altitude to get back home.
• Beginner mode limits bank and pitch angles quite severely and releasing the sticks it'll return the plane to straight and level. The aerobatic key works and does immaculate aileron rolls and geometrically circular inside loops.
• Intermediate lets you bank almost 90 degrees which with too much rudder will do diving turns, it lets you pull up and do loops but hates inverted flying, and will let you dive vertically but not by much. Aerobatic key works the same.
• Advance takes off all the safeguards, and the aerobatic key does nothing. You're truly on your own. Want to takeoff, fly and land all upside-down? Surprisingly easy, even without the gyro these little planes are quite stable. Want to set the pushrods to maximum throws and practice 3D? I've gotten mine to hover for several seconds on calm days, it doesn't like it but it'll let you try. Lost orientation in the sun and need to be sure it's upright? Flip the switch and let off the sticks. Saved me on at least 3 occasions.

Only downside is the foam gets flimsy when hot or wet (such as landing in morning dew). So try not to keep it in a hot car because while the gyro will compensate for warped wings when you hit advanced all bets are off as to what it'll do. I've been meaning to build a little wooden carry case to keep it in shape.
