Big monsters

HJK Big Monster is a F3S high-speed, full-CFRP model for extreme drives. The model is made in full-view carbon fiber and thrilled by even larger hull volume like his little brother. With high-speed F3S drives or turbines, the model reaches extreme speeds. The very good-natured flight characteristics will inspire the professional as well as the ambitious model sportsman alike. The HJK Big Monster is rightly the extreme athlete among the aircraft.

Through the use of CNC machined aluminum molds, HJK Big Monster impresses with its high quality level. The wing's fast MH54 profile with razor-sharp nose and tail rails combine fantastic flight characteristics with extreme speed ranges. Another unique feature is the space available in the fuselage for drive units up to 16s (16 serially connected LiPo cells).

Thus, huge and high-speed external rotor motors can be used to consistently expand the limits of what is possible in model aircraft construction. The hull even offers enough space for a tank of a turbine engine!

The diameter for the spinner is whopping 63 mm for a front or inboard engine. The tail units

can be easily locked and glued to the hull, thus ensuring an ideal EWD. The wing is attached to 3 points with M4 screws.

All in all, the HJK Big Monster is a super-CFK F3S superlative speed model:

+ At the Speedcup HJK Big Monster reached a speed of 511 km / h (14s in one direction, setup available from us). The flight model shows high potential and craves more!

+ Due to the high wing depth, HJK Big Monster achieves an enormous gliding performance (thermal crawler)
+ Extremely good-natured flight characteristics, flies like a coach.
+ Fly with top speed like on rails.

HJK-Speedwings recommends protecting all HJK Sichtcarbon models from direct sunlight after flights. This is because all models are made of Sichtcarbon, which heats up significantly due to its black color. Additionally, storing HJK models in cars, especially in warm temperatures, is discouraged as cars can heat up considerably, potentially damaging the materials of the models.
