• The propeller protector has been improved, the propeller will only seperate from the airplane when it hits something in the state of full throttle, and when you turn the throttle into the middle position or not more than it (half-throttle), the propeller will only stop rotating if it impact something instead of seperating from the airplane, that reduces the probability of loss.
