Hacker C50 (Geared 6.7:1)
The Hacker C50, fitted with an APC E22 x12
propeller (as shown here) is a very powerful
combination and will allow an unlimited 3D
flight schedule. The Speed Controller used was
Hacker’s own Master 0-90-Acro unit, which per-
forms very well and gives nice throttle
response. The batteries are a pair of ‘Thunder
Power’ 6000 mAH Lipo's, connected in series,
which give 10 minutes duration.
Note:
This complete motor/battery/speed con-
troller combination weighs almost 2kg, and you
have to be
extremely
careful with the assembly
of the model to keep the ready-to-fly weight
under the 5kg limit for contests.
C-ARF recommend that you use a separate
battery for the Receiver, to prevent any chance
of R/C interference which can occur when
using a BEC system - or a voltage regulator to
use current from the Flight pack for the receiv-
er. In this case we used a 4 cell 600mAH
Nicad, fixed under the Flight pack support, and
this gave correct C of G with the set-up shown.
Of course, a small LiPo pack for the Rx would
even save a little more weight here.
The speed controller can be fixed directly behind
the motor, in front of the LiPo’s, and secured
with double sided Velcro on a balsa plate. Make
sure there is enough cooling airflow over the
heatsink, which gets quite warm.
The photos show how the 2 bulkheads are
installed. The front of the motor is mounted to
the 2mm thick C-ARF carbon motor mount, with
the standard fibreglass circular plate that is sup-
plied with the motor sandwiched underneath it,
using the four M3 bolts supplied with the motor.
The whole assembly is then fitted to the back face of the supplied carbon/ply nose ring with four
M4 bolts, which pass though the plastic grommets with a 2mm thick carbon washer either side
