I think it is a great looking model and well engineered but not something we would consider at that size for a product. Although there are plenty of big one off models I'd like to take on
I think the kit including retracts is around €23,000 (basing on the cost of their large L39) but then add a P550 which is around €15,000 and you are already at 38k before you've built or added any servos, scale accessories etc... A lot of money certainly.
I wish them the best of luck and hope it does really well as I know the effort and heart ache that goes into designing and manufacturing these aircraft.
