First.....your friend needs a new instrutor. NEVER NEVER NEVER go taxi around an airplane, unless you plan on taking it off. The instructor should have never suggested to taxi around the plane, let alone around the house. Your friend was following directions, however I would question the instrutor's ablities, now

NEVER DO THAT AGAIN!!!

Your freind found out why you do not taxi a plane around.

If you need to break in the motor, put the wing on the plane and run the motor in the back yard.

To your question. You can buy a new fuse from Great Planes. If you are buying the plane with the radio and motor, don't pay more than a couple hundred for it, becasue a new fuse will cost about 80. A whole new superstar select is under 300.

A new SuperStar ARF plane is less than $100.00.

If its really cheap, buy the thing and fix it yourself. It will teach you a few things about the plane, so when you bust one up, you will already have knowledge of fixing them.
