These blades are very well made (for plastic ones) they are balanced great (less than 0.012 grms of difference between four of them),Also they have thickness reductions at the root to provide some degree of Flap in the blades.This does a good job but the tips having the offset I believe presents a problem in that it seems to place too much tip face area and this makes the blades difficult to tune in Hover and in getting the right transitional lift characteristics out of hover.I think that cutting the tips off will help this and once I have acquired some spare blades I will report my findings.
Overall though these are fantasic Blades and I believe that they are the Blade to use on the four and five blade heads!.Not to mention that price which is nothing less than BARGAINLooks great on my 5 blade head. Needs a little sanding to balance but for the price, cant be beat.Recvd a pair as ordered. Haven't flown these on my scale yet, so I can't say how they perform. They are heavy though and long. Ordered a pair of 335mm along with these and side by side these are longer. Hope the extra weight and length translates into a stable flght.Some people lucky to receive 1 blade.i did not receive any .an customer service ignoring me now.so one star from me.dont know what quality is likePeas de reposio na sua caixa de campo otimo para uma subistituio quando tenha uma lenha, s flambam um pouco, tem que ser feito voo papai e mame.ps para montar em rotor de com 4 ps.Nice Scale, not much lift compared to standard bladesooo uygun fyat kaltesn gorecezNo sei o que esta acontecendo pois j a segunda compra que fao de dois pares e s me enviam um.
