Certain manufacturers further customize the way the propeller mounts to the motor. Some have D-shaped (single or double) cutouts on the motor, and the propeller has the missing material; this ensures that the propeller will not loosen itself in flight. Other manufacturers have been known to include other types of specific “male / female” motor to propeller connections as well. Newer propellers have a thread rather than a hole which is opposite to that of the rotation, and the motor’s shaft has the same thread, essentially tightening the propeller when rotating.
Helix labels look so professional it would be a shame if their product was bunk.. BUT after 5 weeks at 400mg of tren e and 300 mg of test per week, I've never looked so good so early on in my cycle, and my sides are under control.. Finally I have found an Aussie UGL that delivers on quality, strength gains are insane and no PIP. Not sure if my diet, sleep patterns or that Im injury has anything to do with these results...shoulders and chest is popping and my strongest body part legs are showing signs my outer sweep developement is finally taking my legs to a bodybuilder status.
