Now that gas engines are affordable and common, it's time to bring back the Giant Scale Performance Series planes. The Extra, Yak, and Cap. It's time. Lets get it done.
It's difficult for them to compete in a market already overly saturated with giant scale airplanes, companies like Extreme Flight dominate the market with a large number of offerings that can be flown as hard as you want and not break them. There's lots of other ones too like AJ Aircraft, PAU, Pilot RC, Aerobeez, Flexx Innovations, Hangar 9, etc. that all have a large portion of the market. I am thinking GP isn't finding the market for them to fit in.
