Default Will any 325mm blades work in the Blade 450x?

After precisely one minute of flying my new heli I sort of panicked and hit the ground with the Blades. Anyway after giving it a good inspection, everything seems fine except for the blades, which came apart a little bit. Now if this were a much smaller heli a little glue would put the blades back together, but I'm not even gonna attempt that with this best. Anyway what I want to know is will any 325mm rc heli blades work with it, or do I need to get the ones made for this heli (which will run me around $40)? Also one question I have about my first flight. When I gave it throttle it spins a little bit on the ground, however in the air it does not do that. I'm assuming this isn't normal? What Settings to fix that?

Any 325mm blades designed for flybarless use should work fine. You definitely don't need to use OEM blades.

My favorites are the Align 325mm carbon blades available in blue or black for less than $20 a set. Very nice quality, look great, and usually well balanced right out of the box.

Regarding yawing while on the ground, have you tried spooling up the blades more gradually?

Best regards,

John

I guess one thing I'll add about different blades is that the root thickness can vary from brand to brand, but I've yet to find a set that wouldn't work on the 450X. I believe the stock blades on the 450X use shims to take up the gap and some others may or may not require the shims. So anyways, just keep that in mind.

The yawing on the ground happens when the torque of the main rotor is higher than the counteracting thrust being supplied by the tail rotor. Like John said, it can happen if the heli spools up too quickly, but it's definitely not a huge problem as long as you're ready for it. One you get a feel for it, you can definitely spool up softly enough that this doesn't happen.

Are you sure?... I have never damaged blades on a stock 450x without tweaking the feathering shaft.

Feathering shaft ALWAYS gets bent. ALWAYS

Spinning on spoolup can happen if the tail blades are at an extreme left or right position at startup.. I usually make sure that the tail blades are at or near neutral position before spooling up.

Went through it recently, twice. Took the feathering shaft out and couldn't tell it was bent, put a new one in and it corrected my issues. All I did was sit it down hard.

Search for RJXHobby blades (have not tried them yet).

Rc-hobbystar, the German KDS seller has them in shop.
There are cheap 15eur ones and the premium in different colors for 22euros

On my 3d I used Align 325d 3g Pro (flybar heli). Flew fine.
According to Monstertronic who sell them customers use them either for flybar or flybarless helis?!?


Some threads tell that suffix “3G“ means originally FBL?
Weird...every dealer and distributor tells his own FBL vs flybar blades story :-).


You will find Align 325e and 325f blades, as suggested above, too.

I use RJX blades on mine. They work great. I'll probably try out a pair of Zeal blades if I ever crash the RJXs.

An easy way to tell if your feathering shaft is bent is to remove one blade and then turn the screw holding the blade holder to the shaft. If the shaft is bent you'll see the other blade holder move in a circle.

Thanks for posting about the main rotor blades. Being a newb I did not know you could use other blades and I bought 3 sets from horizon hobby for about a hundred bucks when I had my first crash. Ouch! I still have two spare sets. At least now I know after crashes to come,I can save some cash with other blades.

The 450X feathering shaft is made of cheese. I've had hard auto landings that bend the feathering shaft while the rest of the heli is unscathed.

I agree. I have had a couple blade touches with the ground while learning to fly. Nothing but just a slight brush and each time it bent the feathering shaft.

Another vote for the $20/set black Align 3G blades. They need shims, but the stock ones work perfectly.

I haven't found the feathering shaft to be any weaker than any other comparable heli out there. Yes if you whack your blades on something you can expect to replace it. I also run $10 blades from ebay and there's not difference between them and the stock blades in terms of performance.

Gaui's X3 is a comparable model and you have to auger it in HARD to tweak the feathering shaft. I put mine in head first in a pretty heavy crash and the feathering shaft was still dead straight!

There are a few other 325-360mm machines that use a larger diameter feathering shaft than the 450X. I love mine, don't get me wrong, but it does have some rather weak areas. Just sayin'.

As far as the OP, you can't go wrong with the Align blems. They're cheap and they fly great!

I guess I haven't augered in my 450x. I have flown it into a goalpost, had a stock servo strip on an inverted punch out, and had a few "forced landings", but nothing too crazy. I agree though, I expect the X3's feathering shaft would be far more durable that the 450x's, it seems to be quite exceptional in this regard.

All the best!
