RE: new to planes
The super cub probably won't take off in gravel. But it is super easily hand launched. If you get a nextar you won't be able to hand launch that. If you don't plan on getting an instructor than your possibility of success is much less than if you get a super cub. The nextar and the super cub are two different types of planes. It's like comparing a dirt bike to a harley. A nexstar wouldn't make a very good park flyer. As it is big and the electric version is somewhat underpowered. The nexstar would be great if you plan to continue the airplane part of the hobby. Where the super cub would be more of a plane to have fun with and fly just about anywhere.
