would having 3 gyros in a 450 sized heli make it a smother or one could say easier to fly?
of course the would only be used for regular flight not acrobatic, so no crazy flips, spins or extreme manoeuvres.

any thoughts would be great.

thanks

Thats called a VBar or Cylock

And they're great for aerobatics, too.

would it reduce the chance of the almost cretin 1st crash

It may, depending on what gyro system you get. Some of the gyro systems have trainer modes that make it easier to fly, but that limits what you can learn.
