When the BLS157HV is too much even for a giant-scale aircraft, the BLS156HV is the perfect alternative. 7.4V speed is comparable (0.12 second/60 deg. vs. the BLS157HV's 0.11), but torque is 292 oz.-in. - more than enough to ensure absolutely first-class aerobatic performance. Includes dual bearings and metal gears like all the others, plus a metal center case for extra cooling.
