13T tail upgrade kit for Soxos Strike 7

The low head speed is not a friend of many models, as it affects the stability and the tail performance negatively a lot. But there is an elegance of flying with low RPM, many pilots like it. The main rotor performance remains satisfying with a 700 class helicopter, but the tail performance is declining a lot in most cases. The new upgrade kit is aimed to increase the performance in these circumstances. This change will result 30% better tail performance - promised by Heli-Professional. 

The kit price is 44.99 CHF at Heli-Professional
