x50 flybarless head has play

[Adam F]

I have about 15 flights on the raptor x50 (with the TT flybarless head ) . I notice that the head has some play , its up and down and when you hold the blade grips and move them out and in I get some play . The play is very slight and has not caused a problem but was just wondering if anyone has experience this . Do i fly it so ? If I have to fix it, how do I ? I love flying this heli so much ,really hope its not a big problem .Thanks in advance .

The X50B I had this spring/summer developed some slop over the course of a few months. I used the factory FBL conversion head. This slop basically amounted to some wiggle of the blade grips. It wasn't a lot and didn't seem to affect flight, in fact the X50 was one of the best flying helis I've had.

As far as fixing it, I wonder if the head could be shimmed. If you can find a shim of the proper size, you might be able to place it between the head damper and spindle spacer. Just a thought.

Here are a couple of shims that might work for you.

Let us know what you end up doing. Hope this helps.

Thanks for the quick reply , I will look in to the shim but kind of hesitant to interfere with it because it fly real good . I let you know what I decide .

My flybar'd head was sloppy from day one.

You can maybe use method i used in my guide for building : https://www.helifreak.com/showpost.p...7&postcount=13

It's about in the middle of post #13 when i ask you to check for the play.

I have flybarred machine but there is no mechanical difference in FB FBL in this.

Thanks Koudy , I will take a look at your post . thanks for the help. .
I just love this heli

I assume it's the same FBL as I have on my X50E? If that's the case it seems all X50's have a little slop in the bladegrips (too little preload on the thrustbearings)

I read in some other forum that Nick Maxwell had commented about it and said its fine but you can put additional shims to make it tight.

+1 on this "My flybar'd head was sloppy from day one"

Some play is expected but this much is out of controll.Cant run light blades half to run heavy china made blades to compensate.My other helis dont have close to this much after many flights and this head only has about 10 on it my maverick fly bar head had zero slop before upgrading to fbl?

Think I will dissasemble the mavrick and see whats interchangable

building my kit tonight and the head is sold as a rock and silky smooth. about as perfect as it gets.

I got around to dismantling the head to see what was going on and really dont see anything as far as its put togeather correctly.The head and dampers are fine and there is no slop or play in and out so dont need to be shimmed.The grip bearings are glued in tight so the only thing it can be is sloppy blade grip bearings.Its so bad on mine that when I threw on some edge blades tracking is all over not getting a clean and tight swirl where you can see the blades give that opposite direction look it got the blurry look like there bouncing around.Im sure its causing havok on my allready way to sensative poopy 3gx.
