I was testing Spitfires 100, at first I was impressed by the design - no washer, no rubber band, 1 1/2 cutting diameter, their were shooting like field points.
After reading number of complains of Spitfires not opening, I examined the blade locking system and the shape of rear tips of the blades (those little wings sticking out) I think that there is small possibility of the blades not opening.
Regardless how small the chance is, I don' t want to play the odds at the moment of truth when I have to concentrate on so many things.
Further more I' m not buying NAP' s explanation that sometime the blades will close after passing trough, as a result of sudden lost of friction, I was playing with them and just can' t see it happening. To me it sounds like very defensive move by the company, obviously addressing more than just a few complans, why don' t they use the same " wanderful" locking system on other mechanicals, all other NAP' s mech' s have O rings.
Please don' t get me wrong, I did not run a thorugh scientific test, and all my Spits opened, and I can imagine the great damage they can cause to an animal. All I' m saying is that I believe that a small possibility of failure exists.
Spitfire users, please be gentle on me[8D]
