<p class=MsoNormal><span style='font-size:16.0pt;font-family:"Arial","sans-serif";
color:#1F497D'>As I said, I used the Graupner 8066 on quite a few planes
without a problem. Not that it matters, but about 4 years ago, I put one in a
Genesis (electric) and the canopy blew off on the first flight. Fortunately, I
was able to find it and it wasn’t damaged. I double checked everything
and saw that the latch was fully engaging into the bulkhead so I flew again.
The canopy blew off again, this time with pretty heavy damage to the canopy and
the LE of the stab it hit on the way down. I used tape for awhile and finally removed
the hatch latch and replaced it with a 4-40 screw. Starting with my next plane,
I’ve been using the red hatch latch because of the extra spring stiffness
and didn’t change anything else about my canopy mounting method and I
haven’t had any problems. My personal opinion is that the weak spring
tension on the 8066 will allow it to get pushed into the retracted under just
the right vibration and/or airframe torque conditions.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:16.0pt;font-family:"Arial","sans-serif";

<p class=MsoNormal><span style='font-size:16.0pt;font-family:"Arial","sans-serif";
color:#1F497D'>I had the 8066 in an electric Partner that I flew all season the
year before the Genesis and the rest of the canopy mounting method was
identical. In fact, the previous 5 or 6 planes prior to that had no problems
with the 8066 latch. My guess is that if you’ve flown your plane with
that latch and had no problems, you probably won’t. I just wouldn’t
pick that latch for anything I build in the future now that I know. If my
comments have you nervous, you can just put a piece of tape over the slot so
the pin can’t move and then remove the tape after your flight. I did that
for awhile with the Genesis and then replaced the latch with the 4-40 screw
after I got tired of doing the tape thing. With a little care and time, you
could probably remove the Graupner latch and replace it with the red one.
Winter’s a lot better time than at the start of the competition season.<o:p></o:p></span></p>

<p class=MsoNormal><span class=EmailStyle23><span style='font-size:10.0pt'>Right
the spring seams weaker that it should be. I like it because I install it
through a bulkhead. Now you have me worried. Maybe I should just go back to
making my own.<o:p></o:p></span></span></p>

font-family:"Arial","sans-serif";color:#1F497D'>I used to use the 8066 until I
had a canopy that kept coming off in flight. The spring tension is too low and
under the right vibration, airframe torque, or whatever, the latch will
disengage because of the low spring tension. I replaced the 8066 with the red
one and have been using them ever since. I used the 8066 on a number of planes
before that happened without a problem. I prefer not to chance it now that I
know.<o:p></o:p></span></p>
