IMHO,

You would wil have a blast with one.

The bigger they are, the better they fly and the Katana gerenally has has a bigger wing area (lower wing loading) than the edges, extras, caps, etc

If you can accept the high costs of engine, servos, props, fuel, etc and you have a vehicle that has enough space to cart the model to the field and back, then go for it!

Check out the GSP Katana as well
