Well, I've got to the mourn the loss of my Estes V-2 (not maxi). My wife wrecked it beyond repair while sitting on the desk here at home.
For some reason, she thought it would be a good idea to vacuum up my hobby area. See where this is going? She's always been a bit, er, clumsy shall we say and ended up knocking off and vacuuming over my V-2. Not even a single flight on it yet.
