North American Sabreliner (N35CQ)

What the heck is a SBR-1? I remember the -40, -60, -70, -75 and the -80 but an SBR-1 does not compute.

SBR1 is just an ICAO designation that lumps all the different Sabre models into one category.

The plane in the photo is a Sabre 65 with Garrett 731 fan engines and a "hard" or heated leading edge wing.

The Sabre 40 and 60 both had Pratt & Whitney JT-12-8 straight turbojet engines with 3300 lbs of thrust per side. The 40's and 60's with their aerodynamic slatted leading edges had no heat for de-ice on the wings at all.

The hydraulic belly board or speed brake has no limitations in the air, you can use it all the way up to red line or the barber pole. It made a heck of a lot of noise at those speeds, but boy did it create an enormous rate of descent with the power levers all the way back
