no worries. there's some good tips and tricks on the site i used to own, sold it a few months ago
www.funcoptermods.com
yes on the gyro
the 'wire' is used to change the pitch of the tail blades. it's a carry over from the
Corona 120 days, don't know if you knew this or not but the funcopter is just a slightly upgraded Corona 120.
if the wire is sticking out too much you won't get enough deflection of the blades and that will take the 'fun' out of the funcopter.
