These are high quality, beautifully finished carbon fiber flybarless main blades for your 700/.90 size helicopter.
Designed specifically for use with the increasingly popular flybarless helicopters, the airfoil and weight balance of these blades has been optimized to give you the best cyclic response and control for your model.
Despite being designed specifically around flybarless applications, these blades can be used on standard flybar helicopter models as well. They excel in FAI/FC3 style flying when used on traditional flybar helicopter models.
Although the majority of these blades are perfectly finished, they are sold as "B-grade finish" blades which means there may be a bit of overspray or smudged paint lines. This in no way affects the quality/performance of these blades and most look perfect despite being sold as B-grade.
You wont find a better price on main blades of this quality anywhere else!
*Perfect for use with Trex 700, Raptor 90, Avant Aurora helicopter and other 700/.90 size helis.
Length: 690mm (bolt hole to blade tip)
Weight: 176g each
Bolt hole: 5mm
Please note: Pattern may vary from that shown.
Smart blades, rigid, balanced & 3D nicely! Could do with a little better finishing around the edges though. 5 mins with a bit of wet & dry, perfect. Well worth the money despite this!I received four sets of RJX 690mm carbon blades today. All of them are damaged and poorly repaired with gray lacquer. The carbon is also damaged so that it is not just a cosmetic problem. I would not fly these blades in the lightest 700 size helicopter.
Hobbykings support offered me $15 for over $180 I paid for these blades. They are all waste.
Feel ashamed Hobbyking for these blades and no quality of service. This was my last order on Hobbyking, after I have done over 30 one with a high volume of order amount.Attention! Don`t buy this blades! This is very dangerous. I bought this blades for testing, but I have made only 4 flights. After not so hard 3d one blade was broken in the air. Hopefully it didnt cause a crash. The blade was bended and cracked near blade grip during performing tic-toc, piroflip and another 3d.
I was lucky that the blade didn`t split into 2 pieces during flight.

Another thing is the weight of this blades 169 g against typical 195-200g. The rotor has less inertia and you must be very accurate doing autorotation. The rotor can quickly stop and quickly speed up. I saw blade stop and did it several times. Very funny!
But safety first! Don`t use this blades.Great blades, look unreal, balance really well cant go wrong for the price. I will definitely buy these again.So far so good. 4 flights on them including some soft 3d, pitch pumps, fast forward and fast backward flight. They're my first 700 helicopter blades, so I'm unable to compare them to any others. They came pretty well balanced.
They seem to hold up well at 2034 headspeed 12.5/-12.5 degrees collective 9 degrees elevator/aileron travel.exellente palles principale pour hlicoptre taille 700 ,trs bonne qualit de ralisation, quivalente a align ou sab en termes de vol mais un peu moins bonne au niveau de la finition, je recommande ce produit pour le prix et en racheterais sans problmesVery good quality even for hard 3D .I have not noticed any differnce between 690 align 3g.
The price is much better.Perfect Blades - Very Good Value for Money. Pretty Stiff. Flying F3C Style.hoi ,
ik heb deze gekocht voor mijn logo 600 se
mooie strakvliegende bladderen
goede balance gewichts verhouding
qualiteit prijsverhouding zeer goed
hebben hier en daar een klein verfschoonheids foutje
niet benoemswaardig,die op het vlieggedrag zeker geen invloed hebben
voor de logo 600 geen vulplaatjes nodig
wel 2 busjes van 5 na 4mm (niet bijgeleverd)
achteraf vind ik het jammer dat ik niet 2 sets bestelt heb
echt een aanrader
These are quite similar to the 600mm blades except they have a 14mm grip thickness.
Please make sure your blade grips supports 14mm before purchasing. Mine only go to 12mm making my purchase a waist. They are great quality for the price and have been able to resell for a 90pcnt of purchase price.
Finish on blades was great, and looked well constructed. If they perform like the 600mm blades they will be great
