My HK450GT has these blades now and they perform perfect. I have the version which says Pro 3D. Going to convert my 450 to FBL. Would these blades be fine or should I better get another kind of blades?
Are these solid CF right through, I recently snap-crashed "Pro 3D" branded blades similar to these and saw a high density type foam in the centre of the blade covered by CF? I guess you do want your blades to give in at some point during a crash otherwise the rest of your heli will be worse off?! Any idea...
Hi Almost every blade in the market, from the cheapest to the more expensive ones, have foam of some sort inside. I own a t rex 450 pro, and I used to fit the RJX blades on it. I found this blades have similar flight sensation and cost a lot less. Not the very best blades on the market, but very good replacement for the money
Can anyone tell me why HK have 335mm blades for 450 helis? My 325mm measure 325 overall, but only 315 from bolt hole to tip? I thought from hole to tip was the way to measure. So are the 335mm actualy 325 blades? I'm confused.
your measuring method is correct.from blade hole to tip should tell the actual length as advertised..for me 3d cf 325 blade is my choice. no issue at all,i am learning 3d using this blade.and it light 21grm only and sturdy constructed
i used these blades on my belt cp v2. i used slighlty bigger than my stock belt cp bladed. but it turned out that it did v good 3-d and i have done several loops after these bladed. before i dont think the wooden blades would have made it possible to do 3-d as it requires bigh pushes and pulls.
yes , basicly if you are learnig the 335 are gona be more stable. Or you can use them for scale models.
325 are very good too. but the helicopter moves faster . SO it is indicated to 3D manouvers.
enjoy and have fun
No they don't break easily.They are strong enough and they are good for 3d flying.I have them and i am satisfied with them.I have seen some other guys using them for very strong 3d!They are satisfied too!
Some people swear by them and others prefer different types. Remember though, if a blade never broke it will cost you a bundle more in repairs to the rest of the heli. Blades don't just break without hitting something and if you hit a tree or something else solid if the blade didn't break the shock would badly damage the main rotor assembly, twist the chassis, fracture the flywheels damage the motor, need I say more. Id rather have a blade which broke on impact than one which didn't
I use this myself, as well as several friends, never seen this blade fail, even in 3D maneuvers.
I'm a regular buyer since I crash my 450 more often than I want to...
However, no one can be 100 sure, with this or other models of blades...
Any of the blade types will probably break if you have a crash. The advantage of Carbon Fibre Blades are they are stiff, heavy, and usually matched better. For just starting out and hovering around, you would do just as well as with very inexpensive wood, or plastic blades as long as you balance them properly...
Yes they DO, especially if you hit something,the object of the game is to not hit anything, But seriously, they are a good blade for the money , I use then on my 450s and my 500s and my 90 nitro converted to electric
NO... These blade are very hard. I hit the street and side walk... And the blade did not break. There is blade sold on ebay that look exactly the same but they are made of glass fiber. If you start, better use Glass fiber blade, because trust me it's better to break the blade than blade grip or bent main shaft
These Blades are very well balanced but beware they are only a single layer of carbon over a foam former there is no reinforcing around the root of the blade and they are not suitable for high rpm over 3000 as I found when I put onto a Beam E4 and as soon as I run up the Rotor speed they Exploded with Horrible consiquence and a longgggg list of repairs on my Brand New Heli. If your only flying casual Great Blades if not forget them they cost too much in the long run!.
I have bought 1 pair of these, and that will be also last pair i have bought. These are semi carbons with loads of foam between it. They exploded in mid air. with a RPM of 2800!!! Broken at the bladeholder. Just schredded to pieces. BUY DECENT BLADES! it wil cost a lot less afterwards!!!
Nice blades they balance well and fly nice. Sets are matched well, less than .09 grams between sets

2 thumbs up!
Well , what can I say. I used to love or still love this blades. Have used 4 pairs already. No problem for 3D , strong spins etc... But just set a new pair after a crash and as high rotation came up , the blades just exploded in air........ full damage on my heli..... I just got a bit scared . I still have 10 pairs left . kkkkk LOL..... Did anyone have the same problem?
Bought to test, still have to fly, but for the moment I'm nor very happy, the part that goes in the arm is not equal, and one blade wobbles up/down unless I tight too much. I had ti put some scotch for a good grip. Hope it last. Surface is a bit scratchy and edges have some very small bumps
