Has anyone had any experience with using pin striping tape on the side of
the canopy for sighting attitude angles?

I have seen this, and sat in a pits with it. My first impression the
focal length of my eyes is such that I cannot find a happy medium.
Either the horizon or the tape is way out of focus. By putting a
sighting device on the wing farther out it is easier to "look
through" the device and see the horizon. Or look at the device and
see the horizon in the distance.
Maybe I just need to admit I need bifocals :(

I am not currently building anything. I have some photos of some that
I could forward if you like.

I was just using this in a Pitts for some aerobatic refresher
training. (I haven't flown much acro for about 5 years and felt it
would be a good idea to have a good instructor help me knock the rust
off.) I know what you are saying in that, the tendency is to focus
your eye on the horizon which makes the tape go out of focus. I found
that I adapted very quickly and using it to determine pitch angle
relative to the horizon was not a problem.
OTOH, something no one has mentioned but is probably significant is
setting a lateral sight-point on the horizon. If you have a sighting
device out on the wing tip it will help you identify yaw when
horizontal or roll when vertical.
> Maybe I just need to admit I need bifocals :(
(Sorry, bifocals won't help because the tape and the horizon are in
the same plane.)

Bifocals will not help. Even with multifocal lenses, you can only focus at one
distance at a time. Putting the sighting device on the wing tip moves it far
enough that the eye considers it at infinity. Then the eye can focus on the
sighting device and the horizon at the same time.

I found this article by accident looking through some old IAC
magazines. I have searched for lots of info on the 55 and never run
across this. I have another article by Allan Cassidy that compares
the 55 and Sukhoi.
Enjoy.

Here are a few photos of a variety of designs.
I would also put a small streamer on the design for tailslides,
torque rolls, and any other maneuvers that are in reverse.

Here is link to a few photos of a variety of designs.

torque rolls, and any other maneuvers that are in reverse.
I also included an article that I found by accident comparing the 55
to a Sukhoi. I had searched for info on 55s and never found this
one. I had seen the review by Allan Cassidy before.
The page also has some old videos - 3 years old. I have some new
video of inverted spins and tumbles in the 52. I'll try to post in
the next few weeks.

Can anyone tell me what the max speed is for flying a 55 with the
canopy open?
Thanks,

Reminds of back in the late sixties (68?). Graham Hill was asked if he
thought using STP (car sponsor) at the Indy 500 (he won that year) was
beneficial. His response: "It doesn't seem to hurt anything and they pa
y
us a lot of money to put their logo on the car, so we use it."
