Spinning up my G4 for the first time I thought the thing was going to flop over it was oscillating so bad. I actually started blaming the CGY750 but decided to get checking the head out a lot more. I found that the tracking was out 4/10s of a degree on one of the grips. Fixed that and it was smooth as silk. Not sure how I got the initial setup off that bad, think I must not have had the heli stand leveled correctly, but totally surprised me because my 90SE would gladly still fly with a whole degree out... it would just shake a bit, not like this...

Well anyways, thank dang goodness for digital pitch gauges! Paid for itself again and the G4 is a beauty in flight.

I have heard odd things about the CGY750 - including some things related to its tolerance to vibrations.

Maybe that was the problem?
The out of track blades freaked out the CGY750

Not sure, perhaps the effects of the vibration were amplified by the FBL unit? It was amazing how smooth it got afterwards... like a glassy pond of water, not even a ripple.

4/10s of a degree ???

How do you even measure that? Or even fix it?

I had that issue with Align 600 Carbon Blade switched to Flybarless type blades and the issue disappeared. I am running a Skookum 360 flybarless system with a spartan 760. Flies great!!

4/10s is measurable and fixable with a digital pitch tool like RCLogger. It just needs to be setup an zero'd out correctly.

Hrm, I have both blade types, currently have "flybarless" type on it. I have had a tough time determining what the difference between the two is though...seems like it means something different for every manufacturer, almost like a "flavor" preference on making just the right FBL blade.

There is an article in RC Heli magazine that talks about the differences between flybarless blades and flybar. They say that the bigger birds like 600mm and up that you can't tell much change between the blades. Since these machines are already some what stable. And where you noticed the biggest difference is on the smaller machines like the 425mm and smaller blade size.

When I put 3g blades on my trex 500 I could tell a difference. The blades are heavier for one thing. And it flies a lot different then it did with the flybar blades. In fact my flying has greatly advanced since switching to flybarless. I can't believe I waited some long.

I will be converting my titan x50 to flybarless, just as soon has I receive the head and flybarless controller. If it flies anything close to how my trex flies. It should be fantastic. I can't wait.

Oh you'll love the x50 on flybarless. I switched mine after only 3 flights with a flybar. I put the compass head on it and use the CGY750 on it as well. It set up perfect, dead dang on first shot, on the combo included carbon blades no less. That thing is rock solid and flies like a guided missile. I'm flying the crap out of those blades still!!! I do have a set of flybarless blades for it as soon as these go whack ;-) Then I can tell you of any differences from first hand, but regardless, the x50 FBL is a sweet machine.
