The HJK Monster1.1 flight plane is constructed in full carbon fiber laminate material (full CFK) and is usable as a speed model for extreme drive trains. This assured a very comfortable using of RC components inside the aircraft body. With high speed F3S drive trains the HJK Monster1.1 can reach very high speed ranges – rightly the sportsman of airplane devices. Neutral flight quality will inspire professionals and ambitious sportsmen as well.
Improvements to the forerunner model HJK Monster:

The manufacturing process and the quality of the HJK Monster1.1 were improved massively by using of CNC milled aluminium shapes. A new modified MH profile of the aircraft wing with razor-sharp borders matches fantastic flight quality with extreme speed ranges. The aircraft body has a large capacity for motor drive trains up to 14s (!) Lipo accumulators – this is a real unique selling point. Therefore, huge rotor electric motors (e.g. LRK motors) can be equipped in order to extend the borderline of feasibility in RC flight modelbuilding consequently. The diameter for the air-screw spinner is 60 mm (e.g. fitting for a Graupner precision air-screw spinner). All tails and the aircraft wing can be located in position easily and be screwed in place to the body. In sum, the HJK Monster 1.1 is a full CFK F3S speed model of superlative.

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.
