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.

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.

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
