Maybe bigger and bigger jets is where the money is. I think the pool of buyers drops though. But maybe the profit margins increase. To wow the crowd how big do models need to get? Makes a 6x12 trailer seem small.
Of greater concern is the additional engineering that should go into these things that may not be happening. Landing gear has to get much more expensive to do the job for more than a few flights. Not to mention the airframes.
SM has so many models now. Too bad they don't have time to make what they have better builds for the money being charged.
