"Typical finished weight of a metal Chipper is 625 to 630 pounds with a Rotax engine and 21" tires. Useful load is greater than 600 pounds, and engines up to 120 HP may be used. With my upgraded Rotax, I'm cruising at about 92 knots with huge tundra tires and long Alaska main / tail gear @ 5.4 GPH. Furthermore, my Chipper is set up with nearly 50 gallons of usable fuel, allowing a remarkable 8 hour range. This has aided my flying into remote wilderness in northern Canada and Alaska."
