Unit Weight (g):
Big and nice propellers. Was already in balance out of the box. Recommend to everyone for nice and slow flying.These props are great, but I wish they were stronger at the hub.Needed a fair bit of balancing for me - was using on tbs disco with extended arm kit - had a crash and two props snapped - going back to 12 inch with normal arms.Really excellent props. I am using them on a stretched HK X650F (about 670 mm) with Sunnysky 2814-11 700KV motors, 30 Amp Blue series ESC and a nano tech 3S 5000 Mah battery. My flight times with HQ 12 x 3.8 props are around 12 minutes before the low voltage protection forces a landing, with these props it now flies for just over 15 minutes. Motors and ESCs remain cool. Ordering a spare set now.quality etc seems pretty good, only down side is the hub seems abit too small for it's size. if it ever breaks apart in flight at the props i'll update this part here again, if not quality seems pretty decent. one blade had abit of bad finish. needs balancing of coursethese are some of the best props ive used for the price they are,These carbon props are very stiff and lighweight, they are ideal for your multi-rotor project, very efficient and give increased power with less current draw.
