I love the swift but its the difference between Roseane Barr and Jen Lopez - both are beautiful women in their own way but I prefer J-Lo (don't know why though!!).

Have you considered that the Swift may not come with the best prop for getting this motorized aileron glider up, up and away?
The Challenger has a prop design that combines the best of a "climb" prop and a "cruise" prop for this motorized glider. Have you ever compared the Challenger prop to the Swift prop? It doesn't take a rocket scientist to see that the Challenger prop should provide some extra
oommph for getting up, up and away compared to the Swift prop. The size and configuration of the Challenger prop offers a better "climb" and "cruise" design then that on the Swift. Do your propulsive airscrew homework.
Swift's motor and battery power are such that a Challenger prop is more suitable for hand launching the Swift then the prop that comes on the Swift. Try launching the Challenger with its prop and then try launching it with the Swift prop. Bingo!
The irony is that at full speed the Challenger prop most likely requires as much or more torque then the Swift prop and yet the Challenger uses a smaller motor and battery then the Swift. The folks at HobbyZone outfitted the Swift with a prop as if the Swift were a zippy aerobatic plane.
