Trex 500 FBL head fit?

[SQRT(-2)]

Will the Trex 500 FBL head fit? Someday I may want to go FBL and the Tarot is $40.

Both have an 8mm diameter main shaft. I had a look at the standard trex 500 main shaft and it has a smaller diameter section on one end.

Same deal with the trex 500 FBL main shaft...

So you will probably need to use a gaui mainshaft.

I dug up an interesting thread on the topic:

You might want to send Sp00fman a PM and ask which FBL head he bought.

And if all else fails you could just spring for an X4 FBL head that is listed as compatible with the 425:

I know as much about going FBL as I do interior decorating. Very little. Hope this post helps.

After a crash I replaced the head with Align FBL. I have only shortened the main shaft of 12mm and redone hole Ø2,6 mm to fix the head.

I am not able to insert the image sorry
