FFF Rest assured, being totally wrong won't be sufficient to stop me posting
Anyhow, folks, all the very informative posts, above, leads me on to another question.
The last time I did any aerobatics, was about 6 years ago in a Citabria. It was a venerable, but docile taildragger, & the only electrical item in it, was its one radio. And it did not have any form of vacuum pump.
I therefore seem to recall that it did not have ANY gyros, but I stand to be corrected, AGAIN!
Its only instruments were: wet compass, airspeed indicator, VSI, RPM guage, oil temp & pressure guages (no DI, AH, or turn co-ordinator)
...... AND a very old fashioned Bank & Slip Indicator
Does a Bank & Slip Indicator have a gyro?
If so, or if not, how are they normally driven?
As I have booked up to go spinning again, in few weeks time, in a C152 aerobat, with an instructor ('cos I am not that brave/mad), I have been reading this thread with interest
