"You mean "mowing" (not moving) 'cause this thing isn't going to get off the ground."

"yeah, but this was all just for laughs anyway. Nothing about hovering (never mind moving) 30kg for an hour is desperately practical :-)"

Euan Ramsay replied to Petar's discussion strong quadrocopter
"Try running some sims in www.ecalc.ch. Amusing exercise...assuming a 90k weight, I can only *just* get hover with 16 x Scorpion S4035-250's, and 10 x 14S 6000mAh lipos built into the weight...and a flight time of 5.4 minutes."

Euan Ramsay replied to Petar's discussion strong quadrocopter
"Given the very basic principle of 1kg = 24-48watts to hover*, you're looking at massive power requirements. Assuming the model weights twice the payload, that's 90kg. So worst case based on above: roughly 4.3kW. So for one hour,…"

"He's probably aiming for high torque propulsion. I doubt a electric power quadcopter can have the sustained lift force for 30kg for an hour."

Brian Yip replied to Petar's discussion strong quadrocopter
"I have been thinking of turbo shaft engines for awhile for my quad copter propulsion system as well. But I'm looking for a lighter and stronger airframe than Ti. My unsolved question is the fuel economy and the thrust it can…"

Jared Reabow replied to Petar's discussion strong quadrocopter
"You make absolutely no sense. You cannot have a quad copter powered directly by a combustion engine And it would be very big or have more than 8 rotors to be able to liftt in excess of 30KG. I suggest if you want to use a combustion engine to…"
