 |
|
I have completed some excellent Unusual Attitude training in a Cap-10 which included loops, rolls and spins and will soon complete additional aerobatic training. Then I would like to try some of these aerobatics maneuvers in my RV-6. However, I am a little concern that the gyro tumbling and/or G forces of aerobatics may hurt my instruments. I have an AI, HSI and S-TEC autopilot all containing electric gyros and would hate to damage them. What has been your experience with aerobatics and instrument damage? Should I be concerned about this?

In my humble opinion, aerobatics should not bother your instruments at all. I do a lot of it in my 6, and everything goes on working fine. Four years of it.

One failed instrument after 5 years, 500 hours, dg…..(not high quality to begin with, made by falcon) mix of loops, rolls, clover leafs, also use to do them In a C150 believe it or not, with no instrument failure in 10 years (about 600 hours)….shouldn’t be a problem IMHO

I'm glad it's worked out for others.
I went through two attitude indicators in a year doing "light" aerobatics
and decided to overhaul my panel to glass.
The first one I don't know the history of so it could have been old to start
with and on its last legs anyway.
But the second was new out of the box and becoming unreliable within a
little more than a year of flying.
In theory, the rate of turn instruments (turn and bank, etc) should be okay,
since they don't care where up is -- just what rate you're turning. But I
think there are some absolute hard mechanical limits inside the AIs, at
least in pitch. It certainly didn't break on my first loop, but like I say,
it didn't last the years and years I expected.
When I looked at the price of a "basic" experimental EFIS compared to yet
another new AI, it was pretty clear that the days of gyros are numbered.
Of course by the time I was done I'd spent significantly more, but my
airplane is way more capable too. 
Just another anecdotal data point.
Scott.
