Generally a medium weight blade works well, the light ones pitch in FFF the FBL ones tend to be too stable in my opinion.

If it tracks fine in FFF then keep the standard ones, i bought about 6 sets of FBL blades sold them all back on normal radix, stable yet agile when needed

Fbl bladed will add to the stability of the overall system. Remember it is easier to make a heli stable if its already stable.

By increasing the weight of the blades and making some changes to the CG of the blades this adds better stability overall when flying an FBL system.

Now, some people are using conventional FB blades on FBL systems and they will have a bit quicker response while stopping and popping but may not track as well in big air or auto as well as the slightly heavier FB blades.

FAI blades similar to FBL blades?
Are FAI blades similar to FBL blades? I've been looking for FBL blades for my Trex 250. They don't exist yet, but

MS Composites manufactures FAI blades.

Below is the only clue I have that ties FAI/FC3 blades being good for FBL applications too:

Can you guys confirm?

Typically FAI blades will be even heavier than FBL blades often over 200+ grams where as FBL blades are in the 185+ gram range and FB blades are around 175+/- grams.

There is that sort of "sweet spot" with blades so that you can get great aerobatic performance as well as auto performance.

But the CG of flybarless blades is different,
after reading the replies, i still do not know what to do..

I'm just trying to look at the benefits of fbl blades, can it be said that fbl blades, obviously designed for fbl systems, will put less strain on your heli's mechanics, servos, electronics ? mainly because
of the cg difference and the way fbl systems is designed and woks mechanically?

2: they are more stable, meaning more accurate for longer periods with less input however the trade off is you loose the pop.

Does it somehow make you feel disconnected from the heli ? Like an autopilot ? or cause slow heli reaction ?

The benefit is that the helicopter will feel more stable in the air and track better during maneuvers. It will also auto better.

Those are the benefits of FBL blades, a good flying helicopter.

Electronics don't care what blades you fly as they continue to do their job either way, it just comes down to how your model feels when it flys and generally FBL blades will give you a better overall feel.

I consider it similar to setting up your tail rotor system properly mechanically first, which then helps your gyro do it's job better/easier. If the gyro is fighting against a poor mechanical setup, then you'll see it in performance when trying to fly fast backwards for instance.

With FBL, a good sound mechanical setup, which to me includes proper CG'd and weighted blades, would help the electronic system work better/easier. I don't think FBL blades ease any strain on the servos or control system, but they can help reduce any unwanted tendencies in a FBL rotor system.

I tested a certain set of FBL blades on my Tazer that I fly NOE (NO Electronics), and these blades were horrible! The heli was unstable in the hover, pitchy in FFF, did wierd things in flips and hard collective climbouts (not at all like another Brand name set of FBL Blades that I currently fly on ALL my birds).

To be fair to these particular blades, I installed an electronic stabilizing system. For the most part, it certainly calmed down the bad tendencies of these blades, but I could see that the system was struggling to keep them in check, for instance in FFF the heli would porpoise, which told me that the blades were trying to pitch the heli up, the electronics were counteracting, pulling the nose back down.

Putting on my Favorite set of FBL blades, and the porpoising disappeared. NO other changes were made. Now the electronics didn't have to fight with the poor blades, making for a MUCH better flying helicopter.

Chris, any chance of revealing both these blades, or maybe through a
PM?
