WHY? Main Shaft Bolts PLAY???

[Cym]

M2x14 socket screws & Main shaft holes, when bolts inserted they have noticable play or wobble, you pick the word. I have purchased 3 sets & they are ALL alike!!!
This causes when assembled play from the gears to the head.

Hi :-)

You are talking about main gear wobble, right?

I have not checked mine upon assembly but they all seem to behave fine. Make sure you only tighten those bolts "snug" or else they will warp the main gear and cause wobble. Somehow it seems that the main gear likes a loose fit.

The 'J' bolt & the bolt just above the tail drive gear, check them out, you will see play. My T-rex 450se V2 has no play.
