Remote Control Jets!
Abbey and I went to the Gardner airport on Saturday morning, to check out the RC planes. I was very surprised when I saw a model traveling very fast, and doing tricks. As I got closer, and stepped out of the car, I smelled Jet Fuel!! I also heard a jet spooling up. RC Jets!! Using real Turbine engines! They cost from $10k – $15k, so it is not something you would take up without flying lessons, or at least knowing the basic forces of flight.
Just Google RC Jets or search on YouTube.com for RC Jets. What a fun hobby.
