Actually Paul, more than "for the best" good on you for doing this. In our hobby, we all know someone who had a family member die, rolled the car into the garage and 35 years later it is still there. That plane was meant to fly and the single best way to honour your son's memory is to let it be flown! It is what he would have wanted. Memories are not stored in things, they are stored in hearts. So, well done my friend, a hard thing but absolutely the right thing.
