I agree Cobra. You sure can lift that kinda weight with the airplanes entered in those competitions. However they are finicky and just not good fliers in general. Not to mention the use of exotic materials and building techniques. Our answers were to the poster's question on a twin of the size mentioned. He may be able to use a Bruce Tharp Super Flyin King and get the job done. But even then the plane would need modification. But certainly doable. The best answer is to use lighter gear. And boost the engine size a little.

BTW I am not knocking you in any way. I am glad you brought those points in. Diversity is what this site is about. Who knows, maybe you gave some food for thought that brings about the solution to the problem.

Good luck with your project.
