NW Helicopters did not build the fast fin and strakes... BLR did.
Definitely. But NW Heli has a knack for building incredibly clean and very awesome Hueys with every option available... except the 212 drivetrain. Probably a testament to the fact that they have a graveyard of H1s that I assume they use for parts to build and/or support their fleet of completions, especially in the US.
Gordy, can you attest to the power of the stock UH-1 tail rotor setup with the BLR toys on a Huey? Never met anyone that said the stock UH-1 T/R was solid (without BLR) when flown commercially at high GW and DA.
