I don't agree with the reasoning of not using a 90 to learn on. I know that a 90 is going to more expensive to operate than a .50 but if you use that reasoning you might as well buy a $29 PiccO. If a person can afford it a 60 or 90 is a great helo to learn on because it has a better presence and is more stable. You can get a .60 or .90 for not much more than a .50 though over all there are greater costs. My 2 cents, If I was learning I'd get a Raptor .60 or .90 and set it up for stability. I can afford it though and it sounds like Mr. harris can too. In fact I would even consider a gasser to learn on.
