I haven't checked but I bet there are no Raven 2 carb ice incidents!
I'd save your energy if I was you. It's quite hard to get carb icing if there isn't a 'carb'...
But then, you already know that...
If injection is not required why did Frank bother to put it on the Raven2???
Because the Raven2 was designed specifically for hot and/or high operations. The Fuel Injectors are obviously going to give you more power than the 'carb' version. The lack of carb icing is an ancillary benefit. Or at least that's my understanding of the situation.
