The Hacker B50
Brushless Series
Masters of Power |
This family of large Hacker motors powers a tremendous
array of models all over the world - from Monster trucks to gliders with
6 meter wingspan...
Like all Hacker Brushless Motors, they offer the highest possible power
to weight ratio, and are versatile.
The direct drive motors are extremely popular in racing boats,
cars, helicopters, ducted-fan jets, and for running with other
reductions, such as belt drive, in Glow 25 to 120-class airplane
conversions.
The geared motors come with a special front motor plate with an
integrated adapter for the heavy-duty Maxon 3.7:1, 5.2:1, and 6.7:1
planetary gearboxes. Combined with a total of 4 motor lengths and
many Kv choices, you can
 match a motor and
gearbox for any application with ease. Two-meter hotliners and F5F
models are super with the B50 S + 6.7:1 gearbox, for one example.
