Unit Weight (g):
Had high hopes for these props but they are extremely flexible and vibrate up and down like crazy at moderate throttle speeds. Unusable.The overall quality is quite good and the price as well. Unfortunately I could not test it on my quad because of missing nylon washers.
In order to install the blades on the hub you need 4 nylon washers. A part any consideration on the reason why they designed that with washers (could have made thicher the blade hinge) and on the difficulties of mounting a prop on the field (specially for an old pal with short sight), the blade are shipped with 4 washers instead of 8.This make them unusable. Besides, apparently HK does not sell the nylon washers separately. Too bad!!!!
