Hey Folks, :peace

What blades should I use for my Trex 550 for a 3D style of flying (Flips, Loops, Tictocs, etc) . Will be using the KBDD 84.5mm for the 550s and the stock align tail blade for the 520s. Any suggestion will be much appreciated!

520mm with 90mm tail

not a thing wrong with the 550's.

I love my 553 Edge blades, but this is one case where I think beauty is in the eye of the beholder. In other words, you can make an argument either way. For me, the heli "feels" bigger with the 550s. Autos are reportedly easier, but I haven't done any from altitude yet, so I can't say. You also don't need as much headspeed with the bigger blades, so you are a little more efficient if you are just sport flying.

Smaller blades are less expensive (at least than the Edge blades), but there are less expensive options starting to appear in the 550mm size that may change that equation.

+1 for 550's, but I think rtmoore4 is right. It's down to personal preference, there's no one right answer.

I like that little bit of extra pop and stability that the 550's seem to give.

Try them, if you like them keep them, if not you can always go back to 520's.

Well said on the above 2 posts:thumbup:
I absolutely love the Edge 553's. The heli really does feel a lot bigger and it is very stable, but still 3D bangin at the same time:peace

Ok thanks to all, I think I will give the edge 553 a shot, but i know my 550 isn't comparable to the 600e pro, in terms of stability and autos. Anyway, I love both helis nontheless :clappp

I tried Edge 553 after almost a year of flying 520's and the heli feels more like the sim now (I fly a 700E on the sim so this not a big surprise actually :YeaBaby:). It's incredible how much of a difference those 30 mm make.

553's all the way. I actually have my 550 stretched w/600 boom and I love the way the heli flies. I don't think you can go wrong with the heli being stretched with 553's.

donahue, is your 550E running a 6s pack or a 12s pack?. did you make any other changes when you stretch your 550E with the 600 tail boom?

Ok, i have finally decided to get a 550mm size blade to try out on my 550 . So, which brand should I get? Edge or Align, and why?

6s 5000 pack 40c Zippy and it flies really well, get the EDGE 553's and you will love your heli even more. Have fun

I believe the chord of the EDGE blades may be slightly wider too, which helps for auto's. They are a little more money though. Honestly, I think you will be happy with either or.

Still love the Align 520's. Flips and rolls quick. May try the 553 some day.

Just used 550's for the 1st time yesterday. I think I may like the 550's over the 520's. It might be my imagination, but it seemed to float a little smoother, and respond better to + and - pitch moves. I will be upgrading to the 700 main gear though, because one hard transition from + to - pitch stripped my main gear out completely.:wow2: Got lucky and brought her back in without incident. :banana

Ok, I just got the Align 550mm blades on my 550. First feeling of the 550 was that it feels large and "floaty" in the air. but i noticed that the tail is vibrating slowly a little bit. Is there any cause for this? btw, i am using the 84.5 kbdd tail blades

If your using the 550mm blades do you need to get smaller tail blades? Just wondering if the blades may clip them in hard manoeuvres?

I'm tempted but was unsure on this issue.

550 blades requires 86mm tail blades. 92mm will hit.

I prefer the 550 blades for 3D and aerobatic autos. There is a big difference in auto performance. Enough to make the difference of landing or crashing more extreme autos.

Flight time suffers with 550s. Obviously you need to run a lower headspeed on 550's, but even then I ended up with 30s less. Also 550's are harder on the ESC and batteries.

All worth it to me since I auto every flight. But for the longer 3D flights with less wear and tear on the electronics/batts 520's are better.

the 520 align blades would not auto?

Of course they auto. Just less hang time compared to 550's.

What kinds of heads speeds are you all running with your 553's ?

I just got a 13T to go with my Neu 1515 2.5DF which is a 1650Kv motor.
With the stock 170 main gear that still gives me a very fast head speed.

It sounds like the stock 550e had a head speed of about 2200 and I may be running closer to 2400.

I'm running a stock tail rotor, but have heard good things about the KBDD's.

I'm using the term "running" loosely. I still haven't had a maiden flight yet.

I`ve used the 520, 550`s and Edge 553`s, now I`ve got some 530 SAAB blades, my favorite so far... 3D all day plus autos are so easy, tons of hang time, never been so easy to do autorotations:thumbup:

What's so good about the Saab's, never used them before, just interested?

They are SAB's... Not SAAB..

Anyhow. ontopic: 603 rocks.:rotf

yes, if your 550 is stretched, think the op's is stock boom:thumbup:
