Here's the link to my video sample. This is a SPAD Debonair with the FutureHobbies 1 W system. The YouTube rendering does not do it justice. Powerplant is a Thunder Tiger Pro 46 with an 11x5 prop, and the plane will probably easily reach 50 MPH. The wings are 60 inches long, and attached with rubberbands. This system is easily transportable by car.

I think it would be ideally suited to what the OP has described, as long as he has the place to take off and land.
