So, be as fussy as you like.

I wondered why you were using a McCauley governor. You're using it to avoid buying another one. Good idea, but it may not work too well. I have the MT governor with the MT prop on the IO-390 and, although there were some problems to solve, it works reasonably well. There are problems to solve no matter which one you use. Nothing is bolt on. Stan Sutterfield Do not archive I just discovered something very interesting. The gear ratio is different between a Front mounted governor and a Rear mounted governor - .947 to 1 (front) vs. .866 to 1 (rear). So that means that the McCauley governor that I have that I originally purchased for use with and O-360 won't even work with the IO-390. This page from the PCU5000 web site is very informative: http://www.pcu5000.com/pcu5000x.htm It details the various ratios and what not. I also found a PDF on the dimensions of the MT governor that Van's sells: http://www.mt-propeller.com/pdf/manuals/e-1048.pdf This MT governor is also 1" shorter than the McCauley governor similar to the PCU5000: http://www.pcu5000.com/pcu5000x_spec.pdf In this picture of the PCU5000: http://www.pcu5000.com/index_i/hmpg_pic.gif the PCU5000 shows an auxiliary control arm that might be very helpful in pushing the control cable out of the way of the fiberglass intake. Although, I think that just moving the control arm in by 1" compared to the McCauley is going to be plenty. At any rate, I've ordered a PCU5000X number "P-520-029/A-947" for my RV-8/IO-390 combination so hopefully I can move forward on this project...

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?
