"Involvement" in the hobby!
Maybe I shouldn't say this.....
but it's a HOBBY to me...all of it.
So I can have an ARF 'ready to fly' over a weekend - great, but if I finished a $200 plane in 20 hours, that plane 'cost' me $10/hr.
On the other hand a $200 KIT that takes 100 hours to build is 'costing' me about $2/hr OF PLEASURE.
It all boils down to YOUR INVOLVEMENT - me it's a 24 hour passion - to others it is JUST SATURDAY MORNING at the flying field.
To each his own.

And besides, if it isn't 'fun' is isn't worth doing!!!!
