Mine doesn't leak in flight or on the ground. The water will enter if
you open it in the rain. So to prevent the water from getting into the
avionics I made a small eves trough to catch the run off and drain it to
the side of the aircraft.

After seeing many past threads on this problem and noting some builders
at Osh who taped the front seam while their planes sat outside, has
anyone done a redesign where the canopy does not use a pin hinge and
expose the interior? For example, Lancair has the fuse sealed, with the
canopy frame laying on this, and tilting up via two C arms in the comb
similar to many car trunk designs. Thoughts?

For the curious, I heard a story about a tip-up guy whose radio went out
passing through some rain. He supposedly poured the water out of the radio
after the flight.
>:O
You can bet I'll be trying to think like a clever water drop when I get to
finishing. :)
If you solve your problem, do tell. Thanks!

Dear Don;
We have just picked up our new RV7a(w/tiltup) from Florida and
did infact get into some rain coming home to the west coast, and yes
our feet did get wet. Once home and in the hangar, I found that there was
no rubber insulation in the tilt up hinge area, thus I believe that we have
found our problem ?

I'm building a tip-up, so for me this is not a debate about that option.
I just have a question for the tip up crowd with experience in IMC...
Does it leak when you're flying through occasional weather? Any pointers
from folks who have faced or addressed this problem?
I would like low odds that my planned glass panel goes zzzzzt should I end
up in some showery conditions...

My tip up did leak in flight, and did cost me a radio repair as a result. I
spent a bit of time working on it and it's been dry for a year now, though
it's probably only a matter of time before it leaks again.
There are several areas of concern:
The front edge of the canopy needs a good rubber seal that fills the whole
gap tightly. This can be tricky to accomplish, especially at the lower
front corners which have to "slide" over the side of the fuselage. This is
a less critcal area, though, as it's not likely water will get from there to
something expensive. When I finally got my installed correctly and tightly
enough to avoid leakage I then had to deal with whistles from air flow
sneaking past, though I eventually whittled them away by gluing in little
bits of foam here and there to fill gaps and damp vibrations in the seal.
The bigger problem is the hinges. I've not looked at the details on the -7
but I _think_ they're very similar to what's on my -6 and it's really tricky
to get it sealed up over the top of the hinges as they extend so close to
the forward skin and need to come up and forward as the canopy opens. If
you're careful triming the skin in this area to leave yourself enough
backing for the seal you'll probably be okay. I had to rely on stuffing it
full of profressional grade caulk and then carving out enough room for the
hinge to travel. Ugly but it did finally work.
The third thing to watch out for are rivets and seams where the skin
attached to the bulkhead and makes the seat for the front of the canopy. In
my plane there are a few small holes where the bulkhead was notched to
folder over in the curve and aren't _quite_ covered by the forward skin.
These have also been filled with caulk. (thankfully they're not visible
with the canopy down)
Finally, I have some pop rivets in my canopy assembly that needed to be
filled with caulk where the stem "popped" out and left a hole in the middle
of the rivet.
I've definitly heard folks compaining about leaks in their sliders too. For
what little it's worth, though, if I had it to do again, I think I'd go
slider and sacrafice the uninterrupted view (which IS spectacular) so that
if water got in it landed on my head and upolstry instead of my panel.
There is also the issue of rain on the ramp and getting wet behind the panel
just getting into the aircraft (which also happened to me).
I've not done it yet, but some kind of removable "splash shield" over the
top of the avionics to protect them has been lurking in the back of my mind
for a while.
