Very nice finish! Almost perfect balance, so I was lucky.
Very stiff and do not bend at all in flight. Quad is much more responsive with these props compared to basic carbon mixed ones.
Balanced them with piece of tape, took 15 minutes x 4 props.
I use them in a 450 class "reptile" type frame, NTM 28-30S 800kv, with 1.9Kg weight, very nice! Thrust is more than enough.pales molt maques i ben fetes. llastima que no vinguin equilibrades. bon rendiment i dures. les faig servir amb un2830 1100kv. variadors de 30 ampers. no s'escalfan gaire. estan molt be pero es tenen que equilibrar.Good and solid product ... but you need to balance it, and if you compare to common plastic slowfly props 11x47, this model gives less trust due to its design.
But for the price ... don't hesitate even a second !!!HK negative censorship police have been out again write comment with something negative about a product and you have a 95pcnt chance that your review will be deleted shame on you HK Let all the reviews good and bad remain otherwise you are a bunch of hypocrites my Propps was just garbage when the hole in the hub was not centeredtrue carbon propellers. they still last on my large quadcopter build. no hit could break them till now. just be sure to put thread locker on the screw, otherwise it's very dangerous if one of these flies off! happened to me and from then on I always put a lot of thread locker on the motor screw before fixing it!Used these on my Tricopter with Multistar 2216 800kv motors. Motors are still cool to the touch! Feels very firm. Finishing could be better but for the price...we shouldn't ask for anything more. One prop has uneven coating and a little of the CF was exposed. Had to smear some CA to patch that and re balance. Will need some balancing due to the uneven finishing. But good product overall. Do check for cracks or wear pre and post flight! Stay Safe!Have tried them , very stiff, but not using them for now, they have less flight time than my gws 1047 props.Awesome props - required little to no balancing. These have taken lots of hits and still going strong - have lots of bite to them and very powerful for my qav400 - have ordered more as backup.
