How fast do you fellows have to fly to get the tail to shake?
I'm still building my first HR-II, so I don't have any real-life
experience with tail shake. However, based on information from the F1
blog, I have added HS skin stiffeners and a HS spar reinforcement to the
thick-skinned -4 tail.
Here are the details:

Hi Danny can you describe the "tail shake" and how when it occurred?
Also could you detail your "upgrades" to the tail components ? I have a
nice -4 empenage with .020 control surface skins. I was considering
several reinforcements to the the horizontal and vertical spars / skins
, so any info would be great. I have heard the term "tail shake" but
couldnt find any info on how it happens etc and how to fix it other than
use .020 control surface skins ? Thanks for any advice / pictures

I pulled the horizontal stab off it to beef it up with some skin
stiffeners and spar doublers. I had too many "OH
SHIIIIIIIIIIIIIIIIIIIIIIIT" moments with the tail shake. With the recent
incident in CA I decided it was time to try and fix things. While I had
it apart I've up dated the GPS, autopilot and changed the stick to 4130.

| Subject: | Rocket - your TAS and stall speeds? Not book figures, I mean |
- yours
Guys, a quick question? I know the official answers are on FAQs all over t
he place, but would like no-BS from the horse's (pilot's) mouth answers. My
HRII seems to give me about 198 knots TRUE airspeed, at, say 6000 feet, WO
T, 2500 rpm. I would be interested to know in your figures - TRUE airspeed
@ power settings, sea level and at altitude, plus whether you're flying an
HRII, an F1 (Hershey Bar) or F1/Evo/tapered wing. Also, what airspeed does
your aircraft stall at?
'Ppreciate it. I'm toying with upgrading, although my trusty steed has give
n me 700 happy and troublefree hours, and I wouldn't switch her out lightly

He Lee,
I missed the 4130 stick story, why you changing it. Did you bend yours in
an 8 G Hornet pull?
