Please, enlighten us. :D

Old ATI too... Assuming this was probably the reason.

One would have to, to supercharge one without the legacy blower that the Thunderbolt and Hurricane had.

It would certainly assist in keeping the wind down tones loud, in comparison to say an unassisted rotor (like that of the T-128 or the 2001) where they get quieter as they spin down as less air is being sucked in; this design seems to keep the air supply up to the rotor. If you look for my Year 12 D...

Was $750 Not everyone can justify that cost if it's going to be used a handful of times, especially when the shipping cost would be frightfully expensive. Consider the cost of a 200kg siren head plus everything else that was listed in the auction if someone in Florida had it shipped from Oregon. Th...

The only thing is that the port size will have to change, and that'll reduce what already meager sound output the 2001 already has. Double edged sword. The lower pitch would actually carry further than the current higher pitch, but lower the dB SPL. It seems all Federal cares about is numbers on pa...

It would begin to look pretty dodgy pretty quickly when the court takes into account the other bidding processes that failed, especially when Federal conveniently dro...
