I do. I cannot afford not to.

On that note,
There is nothing on a plane that is more important than a good working receiver and battery packs and yet these are the most frequently overlooked parts. It just makes good common sense to make SURE that they are in good working conditions and repair or replace them of necessary. You can lose an engine, a servo or even have a control surface fall off and still get the plane down, but if you lose a receiver or battery pack, unless you are reall lucky,,, its all over.
