$5 of electricity to lift an airplane 10,000 feet definitely seems low.

If you want to be really smug, you could say a gas powered plane requires $0 of fuel to glide for 30 minutes

Now that you mention it, they specify a maximum total weight of 25,000 lbs, so at 100% efficiency it would take 339MJ of energy to lift the fully loaded plane to 10,000 ft. That can be converted as 94 kWh, and at the current cheapest electricity price in the US of $0.1235/kWh, that's $11.63

Therefore, it is literally impossible for this plane to reach 10,000 ft for $5 fully loaded.
