TIG 520mm carbon fiber blades are ultra stiff and nicely finished. Will easily handle the hardest of 3D manuevers.
Length: 520mm (bolt hole to blade tip)
Weight: 97g each
Blades are OK for the price, my pair came well balanced and i use them on my HK550 modded to DFC for sport and soft 3D flying without any problem... Blades color is black and not very shining finish... I added some yellow adhesives to make them more visible in the air...Pales reu rapidement (1 etoile!).Les miennes sont INUTILISABLE tout simplement!!Une et courbe cers le bas et l'autre vers le haut...bonjour le tracking!Pour ce qui est de la finition,les bord d'attaque carrment ponc a la main (a se voit,plus de verni et rayure papier de verre).une d'entre elle a un eclat sur sont bord d'attaque en plein milieu de la pale,et ce n'est pas due au transport.Vraiment un tres mauvais choix!!
and one thing more, the blades are NOT stiff at all!!! it is a littel like plastic, i think the carbon are extremely thin, i buy a lot from hk i have over 115 orders-hk give some credit here....worst ever- orderd 2 sets one set is nearly ok- but other set are completly useless-on blade is bending up from middel about 20mm and other bending Down about 20mm- complained to hk and sent Pictures together with warrant claim and they say that they will help me- but guess what,,, nothing happens.
spend 82dollars one nothingI use it in my Logo 500 SE Flybarless and the blades are awesome! Well balances and a lot of noise :-) Only little surface finishing faults, thats why 4 Stars in QualityI have had very good luck with the 425mm version for my HK500. These ones balance so well with very little tape needed. CG was almost spot on with out tape too. The finishing was 98pcnt there as I found it didnt have as much shine (clear coat) like my 425mm. No shims with this kit either. I do like the hologram sticker but would have like to see it on the underside instead of on the top of the blade. The roots are very thick and finished very well with a copper insert for the bolt.
All up and very good quality blade set for the HK550.Overall, the finish is pretty good for their price. My blades were pretty well balanced. Not as good quality as big brand blades, but for the price who cares?Remove my Edge 523 from my logo and bolt this blades on, tracking is perfect and fly just as good as the Edge. Stiff and great for 3D, will buy again
I use these on my Gaui 550 , the stock motor turns these no worries, they track great. I highly recommend these for the sports style type flying that I do.
