I built quite a few of those kits. Names changed but I had KYO, TMHK, Eureka, Mauritaka, They weren't great kits and were really sparse. They had nice spun cowls, the shock absorbing gear was not the best, The wheels looked good but I had them come off the rim often and they never gave you enough sheeting, not that you really wanted to sheet it as it would be too weak. I strip planked the fuselages and added more stringers to stiffen the framework. the big ones required really beefy control systems and they pulled like a team of mules. I weighed about 155 lbs at that time. The smaller 40 sized warbirds were great though and I probably liked the Bearcat best. Would I want one now, no! not even to put on the shelf. Like many things in the hobby they have a reputation far in excess of their real worth.
