This is a d*** hobby, If he can not afford a crash he has no business in the hobby, Tell him to stick it where the sun don't shine.

Lets see
Bad battery, Get a new plane form battery manufacture
Bad switch, Get a new plane from switch manufacture
Bad fuel tank, Get a new plane form fuel tank manufacture
Bad servo wire, Get a new plane from servo wire manufacture

Yea, just keep on dreaming.
