Default Switch vers RJX

I have a D380 that flies super with Switch 383s but wonder about RJX.
Looking at the pics they esp. look different at the root.
Anyone try both the same size. I run my D380 3300 and 3450.

I have both for my 500. Switch is basically rebranded Edge blades. I have and still not much of a fan of them. A lot of people like them though. I have RJX blades and at least with my HD Cell 500, they perform great. I don't know about your size, but I personally like the RJX blades better.

Only Aligns I use is on my 550V1. The head speed isn't that high on it.
Other that that I wouldn't trust them. Besides the balance is usually off. My 500L came with a set 7.5 grams off and took lots of work to balance them and then after about 10 flights they fractured around the brass insert. There good for maidens and while still learning and crashing.
I use blades with a safety strap and are grade 1/A factory balanced.

Well Switch vers RJX. Put 520s on my S500G, they weighed 105 grams each for a total of 210, weight real close and cog good but on a blade balancer with the magnetic poles the one hit the table. Amps shot up and internal ESC temps jumped 25deg and lost flight time. Even lowered the head speed a tad from 2700. Went back to Switch 500s 86grams and amps as well as ESC temps dropped and flies great.
The 380s for the D380 perfect weight and cog, perfect on the blade balancer. First flight noticed lack of lift. When hanging the RJX blades they had no lead characteristics at all while the switch had a slight 2mm lead and now the RJX blades are tossed aside.
Maybe good for paint sticks?

So you are trying to do a comparison with RJX 520 and Switch 500? Trying to compare apples and oranges? You have 40mm more of surface area, of course weight and everything else is going to change. I have Rail 516 and I can tell a difference from my 516 and 500 mm blades. I prefer the 500mm better.

I have not had any issue with the Align 360s I have not tried the 380s.

The same goes for switch and RJX, their QC seems great I've had some RLX that were out of balance, but only just a little

Apples/oranges is blade size per each heli and performance.15G heavier for 4% longer blade same width killed agility and what good is the high quality finish if the balance is that bad for a blade that heavy.
The 380s had no lift with dimensions the same as Switch except the RJX was 1mm thicker. Yup apples to apples and oranges to oranges blade comparison per 500 and 380 sized heli and the RJX didn't cut it.
Even know what lead or lag characteristics is? that determines blade performance besides weight an width? RJX had no lead.

I get it, throwing a jab in there at the end. To be honest, I am 47 yrs old and not an up and coming pro. I don't worry about whether a blade is a few grams heavier. I fly it and see if I like it or not. If I do I keep it. If not, it's gone. All I was trying to say earlier was that comparing weights of different length/brand blades isn't going to be a direct comparison As you and I know, adding and subtracting length can affect different factors.

Same here, as long as they track ok and don't cause vibrations, I can dial most in to fly how I like with my FBL settings

Picked up some Align 380s for the heli I'm working on right now. They sure have a good price on them. Hope they aren't as awful as the OP said they are. I haven't got to balancing them yet so I don't know yet on that, but if they don't hold up that pretty much nixes the low price.

Over the years I've used align blades, I've seen one lemon pair of 360s that were way off(2g IIRC). Occasionally align can do that, but to be fair I've also gotten Edge blades and Mavrikks that were awfully unbalanced.

Otherwise I have never had an issue with them. I let multiple pairs of 360s scream at 4100 on my x3 and its been great so far. Run many pairs of their 520s at 3000 rpm and got their 720s on my max at 2450. They hold up just like any Funkey made blade I've seen.

I did take time to get them dialed in but they didn't cut it. The G500s is already heavy as everyone knows and the heavy blades although stable killed the agility no matter what and was a dog to fly with the RJX 520s not to mention the balance issue.
The D380 lost it's pop and unlike the 420 has higher disc loading. Added pitch, increased the S pitch curve added roll rates on both the 500 and 380. No fun to fly at all.

The only problem with Aligns is with high head speeds, they have a tendency to fracture at the brass insert. My 500L at 3200 cracked both blades with not to many flights.
I run Switch and KDBBs and never had them crack around the brass inserts.

To be fair, blades that are 7.5g off are probably defective in more than one way. I wouldn't even bother balancing a pair of 700 blades that much off, nevermind 500 sized heli. Good blades are made to be passable out of the box with no balancing and should be within .1g - .2g of each other. 7.5g is ridiculous.

Have you failed a pair that was reasonably balanced out of the box?

I plan to run those Align 380 blades at 2800 rpm. I was thinking 3000 rpm, but from what I've read 2800 is still pretty punchy with a Protos 380. Would rather get the longer flight time as long as it still has good power.

The RJX 520s weight was close, made them perfect with cog spot on and then on the blade balance the one dropped hard to the table like the brass insert was off and could not balance them. The Aligns with my 500L, junk,7.5G off and just did a set of Align from a 470 kit and one took a entire width of packing tape to balance them.

Align reversion their 425mm blades this year with bigger brass insert, no fracture anymore.

RJX is not on the cutting edge of blade design.

Yes the Switch molds are from the Edge blades in the sizes available back then. I feel they are dated. The 383 Switch was a brand new size designed from scratch. After trying 4 different brands (not RJX), they have become my favorite on my Goblin 380, more lift and bite than the others.

Seems a bit like an overstatement for making the EDGE 353 mold 3cm longer
