Bud Warren of Geared Drives offered his congratulations to Frank Braun of Yucca Valley, California, on the recent successful first flight of his Bearhawk with a Geared Drives LS1 firewall-forward engine package. This is the first Bearhawk to use the Geared Drives package.
According to the company, Braun reported engine temps in the 160 degree range, commenting that the gearbox temperature was so low that the EFIS showed it in the yellow. Braun said he expected gearbox temperatures at least the same as the engine. However, it is typical for the Geared Drives PSRU to operate at a temp much lower than the engine, the company says.
