Now that you have flown glo, why not try electrics?

You can go with slow flyers that you can fly in front of your house, or somethign like a twin jet that screams through the air at 70 MPH on two electric motors.

Zagi wings are fun, super aerobatic and almost indestructable!

Or go fully 3 D with a 14 oz cobra that is made out of EPP foam. If you crash, you bounce!

Maybe an IFO. Essentially a flying wing made out of carbon fibre rod and ripstop nylon. You can fold it flat and put it in your suitcase and take it with you. Fly it in the parking lot of your motel. It can handle some wind, fly in a Gym or even fly in your office.

Just some a thoughts.
