Heli-Profesional develop this machine using the original Strike 7 as a base, taking all the suggestions for improvement and making the STRIKE 7.1, the main priority was to increase the tail speed. The gear ratio is new at 1: 5.05. This means that a very good rear performance can be achieved even with a «low RPM». As a result of the reconstruction, they made improvements and changes also such as freewheel (Autorotation Hub), belt tensioner, canopy lock system, rotor head damping & others. The 5 different colored canopies, which also come with the matching rotor blades, round off the new development. This enables us to fully cover your needs. The new soXos STRIKE 7.1 is not just a helicopter, but an extremely convincing product that claims absolute market leadership.

• Made from a one-piece milled aluminum mainframe for minimal weight and maximum rigidity. 
• The intelligent design allows easy maintenance and replacement of individual components. 
• With the battery quick-change system, the batteries can be changed easily and quickly. 

• Thanks to the large battery compartment, Lipos up to 12S-6500mAh can be used. 

•  Heli-Profesional innovates again with a more robust simple system to lock the Canopy

• All common engines of the 700 to 850 class can be installed, with 6mm or 8mm shaft diameter. 
• The motor pinion is additionally guided at the bottom by a ball bearing. Thus motors with any wavelength can be installed. (At least 20mm, maximum 60mm) 
• The gear ratios go from 1: 7.94 with 19-pinion, to 1: 10.06 with 15-pinion.

• Strong and short rotor head for maximum precision in extreme maneuvers. 
• Specially developed rotor head damping for the highest precision.
• Direct and play-free control of the tail servo to the tail rotor through the torsion bar. 
• High quality of the rear timing belt which prevents a static charge.
