Just a side note............My RC Allen electric gyro has been the LEAST
reliable part in my entire airplane. I have had it back to their shop for
repair and overhaul three times, and finally demanded that they replace it
entirely. The new one has been in service for about 6 months now, and seems
to work OK, but the original one was terrible.
