Warbirds
It is amazing that you can maintain the degree of quality that you do for the prices charged. There is nothing like competition to keep manufacturers on their toes. I for one wish you continued success and hope that the quality of your products improve even more!
That said, I can tell you that I have built a Bobcat and began my P-38. Although there were a number of P-38s on the market, one of the reasons I purchased yours was due to its wingspan. For IMAA competitions, single-winged warbirds must have a minimum 80 inch wingspan or, be quarter-scale. I should think you would capture a larger market share if you built some others with this is mine. The P-61 Black Widow would be popular, especially if it is designed to take air retracts.
