公牛的Diatone鼻子整形螺旋桨5×4.5（CW / CCW）（红色）（2对）
Unit Weight (g):
they need to be balanced . but ye , its a propProps are well-balanced out of the package. After crashes, they can be bent back to straight and reused. Great value.
(Using them in a ZMR250, built with a nice, cheap frame I got from nyplatform on e_bay. I wasn't going to mention that, but the HK site rejected and erased my previous review as being too short, so here's some more text.)great props they are quite tough dont break to easy the are stiff but if you crash you can bend them back to shape most times
just brought 60 moreHelices perfectas para empezar a romperlas al primer accidente. Buena calidad y por lo general bien calibradasCool red blades. Efficient like gem-fan but cheaperThey work really good but you need to Balance them. Check it before the First flight. But for that Price a Bargain.Great props!!!! way better performance on my 250 quad than the standard 5030. i will never fly 5030 again.Cheap, strong and reliable. Awesome thrust. Definitely purchasing more.Excrement propellers. No need to be balanced, give heaps of thrust and are hard to break. They bend and can be pushed back in quite a few times without loosing stiffness. Recommended to get especially for this priceReally well balanced out of the bag.
They are really stiff, yet bend on impact. You can re-bend/straighten them a few times before they become too damaged to fly.
LOTS of thrust too, compared to 5045 Gemfans, even the carbon reinforced ones.
