Bedford,

I scratch designed a weed whacker sport plane that I’ve been flying for years. It’s my all purpose fun plane and flying test stand. 80” span, 14” chord, about 14-15 lb empty depending on what’s installed at the time. Our field is at sea level with a 500 foot paved runway. I had a Quadra 35 on it at one time and wanted to see what it would lift. I hung a 1.5 gallon water dropping bucket underneath and had to add two 5.5 lb barbell weights before I ran out of runway length to get airborne. It still had some climb performance to use up. I’m guessing it might have hauled another 5 pounds if I had more runway?

It got me thinking about range. The Q35 drinks about an ounce a minute at full power, and does at least 60 mph wide open. 60 is a mile a minute, at an ounce a minute, is a mile per ounce. 21 pounds of gas at 6 lb/gal is 3.5 gallons, which is 448 fluid ounces. So 448 miles covered in about 7 and a half hours. And this is with nothing done to maximize efficiency. Yours should out do that by a good bit?

Are you building it for, fun or for an event??
