boomstrikes during chaos on my dyna-x....
hey guys!
this has been bothering me for some time. while attempting to do the chaos. my blades would strike the boom.
i shimmed the heck out of the blade grips. now right after lifting off the heli would start oscillating.
i'm using the ramster metal hub, the center support inside the hub and T&T blade grips.
pics of the heli is in my gallery.
anyone out there have a remedy for this problem?
much thanx ---(mille man)

Milli man do you have hard dampeners in your Dyna? also do you have the center bearing in the head?

I have never had that happen to me. Also is your boom support stiff and fixed in place.

Strike
yes, it happens to one of the pilots with Dyna-X during Hard 3d, the reason was that the Main blades were not tighten enough in the blade grips.
if you planning to do hard 3d, make sure to secure this point

dampners
even with stock dampners and central unit it should not be possible to make boom strike unless the blades you use are very -very flexible.

we do have the hard dampners, and also the central unit.
